What is the Formula of Sum of Cubes of n Natural Numbers?

Answers

Answer 1

The formula for the sum of cubes of the first n natural numbers is:

(1^3 + 2^3 + 3^3 + ... + n^3) = (1 + 2 + 3 + ... + n)^2

What is  the formula of  sum of cubes?The sum of cubes of the first n natural numbers is the sum of cubes of the numbers 1, 2, 3, ..., n.To find the formula, we can start by using the formula for the sum of the first n natural numbers: (1 + 2 + 3 + ... + n) = n(n+1)/2.We can then cube this expression: (n(n+1)/2)^3 = n^3(n+1)^3/8.Expanding the cube on the right side, we get: n^3(n+1)^3/8 = n^3(n^3 + 3n^2 + 3n + 1)/8.Combining like terms and simplifying, we get the final result: (1^3 + 2^3 + 3^3 + ... + n^3) = (1 + 2 + 3 + ... + n)^2.This formula can be used to efficiently calculate the sum of cubes of any set of natural numbers, without having to sum the cubes individually.

Step-by-step explanation:

do it

Answer:

Step-by-step explanation:

The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope and b is the y-intercept.

To find the slope and y-intercept of the equation 2x - 6y = 24, you can first isolate y by adding 6y to both sides and then dividing both sides by -6. This gives you: y = (-1/3)x + 4

So, the slope is -1/3 and the y-intercept is 4.

we plan to turn over the first 3 cards in a well-shuffled deck of 52 cards. compute the probability that both the second and third cards are the same suit.

Answers

Answer is 1/104. Probability is a branch of mathematics that deals with numerical descriptions of the probability of an event occurring or the probability that a statement is true.

What is the probability that both the second and third cards are the same suit?

Probability that the first card is a club = 1/4. (There are 13 club cards in the deck, and 13/52 = 1/4). Probability that the second card is a 3 = 1/13. (There are four 3 cards in the deck, and 4/52 = 1/13). Probability that the third card is red = 1/2. (There are 26 red cards in the deck, and 26/52 = 1/2). The probability of an event is a number between 0 and 1, where 0 represents approximately an impossibility and 1 represents a certainty. The higher the probability of an event, the more likely the event will occur. A simple example is mining a fair (impartial) coin. Since the coin is fair, both outcomes ("heads" and "tails") are equally likely; the probability of heads is equal to the probability of heads; and since no other outcome is possible, the probability of "heads" or "heads" is 1/2 (which can also be written as 0.5 or 50%).

Probability that the first card is a club, the second card is a 3, and the third card is red = 1/4 * 1/13 * 1/2

= 1/104

Jackson invested $320 in an account paying an interest rate of 3. 2% compounded

continuously. Assuming no deposits or withdrawals are made, how long would it

take, to the nearest tenth of a year, for the value of the account to reach $410?

Answers

If Jackson invested $320 in an account paying an interest rate of 3. 2% compounded continuously, assuming no deposits or withdrawals are made, it would take: 3.37 years

for the value of the account to reach $410

To solve this problem, we can use the formula for continuously compounded interest:

A = P * e^(rt)

where A is the final amount, P is the initial amount (320), r is the interest rate (3.2%), and t is the time in years.

Solving for t, we get:

t = (ln(A/P)) / (r)

Plugging in the values, we get:

t = (ln(410/320)) / (0.032)

Approximating this, we get:

t = 3.37 years, rounded to the nearest tenth of a year.

So it would take about 3.4 years for the value of the account to reach $410.

Laurie sold a house and made a commission of $14,050. She charges her customers a commission fee of 2. 5% on the selling price of the house. How much was the selling price of the house Laurie sold?

Answers

The selling price of the house that Laurie sold was $562,000.

The selling price is the amount paid by the customer to purchase the goods. The actual selling price is the amount paid by the customer for a product or service. This is the price that is more than the cost of products and includes a proportion of profit.

The cost price of an item is the amount spent to buy it or the price at which it is manufactured.

Let's call the selling price of the house "P".

The commission fee of 2.5% on the selling price of the house is equal to 0.025 * P.

Since Laurie made a commission of $14,050, we can set up the following equation:

0.025 * P = 14050

Dividing both sides by 0.025:

P = 14050 / 0.025 = 562000

When Kyle doesn't study for his tests, he has a 45% chance of passing. If Kyle didn't study for15 tests this semester, what is the probability he passed at this semester?

Answers

The probability that Kyle will pass all 15 tests if he does not study for them is approximately 0.0017.

This is because the probability of passing each individual test without studying is 0.45, and the probability of passing all tests without studying is equal to 0.45 multiplied by itself 15 times, which is 0.0017. This means that the odds of Kyle passing all 15 tests without studying are very slim.

Mr chua bought a vanguard sheet with dimension 75 cm by 90 cm . He cut squares of identical size from the vanguard sheet such that there was no wastage


(a) What was the largest possible length of the side of each square he cut out?

(b) What was the total number of squares he cut out?

Answers

Answer:
(A) - The largest possible length of the side of each square is 15 cm.

(B) - The total number of squares he cut out is 6750 / 225 = 30 squares.

Explanation:

(a) To find the largest possible side length of each square, we need to determine the greatest common factor of the length and width of the vanguard sheet.

The greatest common factor of 75 and 90 is 15, so the largest possible length of the side of each square is 15 cm.

(b) To find the total number of squares he cut out, we need to divide the area of the vanguard sheet by the area of each square.

The area of the vanguard sheet is 75 cm * 90 cm = 6750 square cm.

The area of each square is 15 cm * 15 cm = 225 square cm.

So the total number of squares he cut out is 6750 / 225 = 30 squares.

(a) To find the largest possible length of the side of each square he cut out, we need to find the greatest common divisor (GCD) of the lengths of the two sides of the Vanguard sheet. The GCD can be found using the Euclidean algorithm, which states that the GCD of two numbers is the same as the GCD of the smaller number and the remainder of the division of the larger number by the smaller number.

75 cm and 90 cm have a GCD of 15 cm, so the largest possible side length of each square is 15 cm.

(b) To find the total number of squares he cut out, we divide the area of the Vanguard sheet by the area of each square:

Area of Vanguard sheet = 75 cm * 90 cm = 6750 square cm
Area of each square = 15 cm * 15 cm = 225 square cm

Total number of squares = 6750 / 225 = 30

So, Mr. Chua cut out 30 squares of side length 15 cm from the Vanguard sheet

Answers

We can use (A) V = 16lw as a volume function.

Because the volume of a rectangular box is given by the product of its length, width, and height. In this case, the height is fixed at 8 cm, so the volume would be calculated as V = 16 x l x w, where l = 2w.

three sandwiches were given to each adult and two sandwiches were given to each child that went on the field trip. there were 40 people on the bus and a total of 89 sandwiches were given out. how many adults and how many children were on the trip ? (PLEASE HELP)

Answers

Answer:

the number of children on the trip=31

The number of adult=9

Step-by-step explanation:

Let's call the number of adults on the trip "a" and the number of children on the trip "c".

We know that:

a + c = 40 (the total number of people on the trip)

And:

3a + 2c = 89 (the total number of sandwiches given out)

We can use the first equation to solve for one variable in terms of the other:

a = 40 - c

And substitute this into the second equation:

3(40 - c) + 2c = 89

Expanding and simplifying:

120 - 3c + 2c = 89

120 - c = 89

Subtracting 120 from both sides:

-c = -31

So c = 31, the number of children on the trip.

And the number of adults on the trip, a = 40 - c = 40 - 31 = 9.

Answers

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is 9980

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is calculated by summing the area of each subinterval under the midpoint of the interval.

The formula for the midpoint Riemann sum is given by:

Sum = (width of interval) * (height of midpoint)

For this problem, since the width of each interval is 16/4 = 4, the midpoint Riemann sum is calculated by:

Sum = 4 * (1 + (16/4)^3 + (32/4)^3 + (48/4)^3)

Substituting the values for each midpoint, we get the following equation:

Sum = 4 * (1 + 4^3 + 8^3 + 12^3)

This simplifies to:

Sum = 4 * (1 + 64 + 512 + 1728)

Answers

There are 23,311,945,600 possible ways to deal the cards to the four players and choose one card to be turned face-up in the middle.

We can calculate the number of ways to deal the cards to the four players and then multiply by the number of ways to choose which card is turned face-up in the middle.

First, there are 24 choose 5 ways to deal the first hand, since each player receives 5 cards. Then, there are 19 choose 5 ways to deal the second hand, since there are now 19 cards left. Similarly, there are 14 choose 5 ways to deal the third hand and 9 choose 5 ways to deal the fourth hand.

So, the number of ways to deal the cards to the four players is:

24 choose 5 * 19 choose 5 * 14 choose 5 * 9 choose 5 = (24! / (5! * 19!)) * (19! / (5! * 14!)) * (14! / (5! * 9!)) * (9! / (5! * 4!))

Now, we need to multiply this result by 4, since there are 4 possible cards to turn face-up in the middle. So, the final answer is:

4 * 24 choose 5 * 19 choose 5 * 14 choose 5 * 9 choose 5 = 4 * (24! / (5! * 19!)) * (19! / (5! * 14!)) * (14! / (5! * 9!)) * (9! / (5! * 4!)) = 4 * 5,827,986,400 = 23,311,945,600.

How to Calculate Maturity Value and Interest on a Loan?

Maturity value and interest on a loan can be calculated as follows:

Maturity value: it is the amount of the loan plus the interest charged on it. It can be calculated using the formula:

MV = P + I

where MV is the maturity value, P is the principal (original loan amount), and I is the interest charged on the loan.

Interest: it is the amount charged by the lender for the use of their money. It can be calculated using the formula:

I = P * r * t

where I is the interest, P is the principal, r is the interest rate, and t is the term of the loan (in years or days).

Therefore:

Exact interest: 4,400 * 6% * 172/365 = $375.44

Answers

The best surface tolerance and finish would be gotten if all inside vertical corners had a fillet radius of (b) > 0.125 inches.

The choice of fillet radius is an important factor in determining the surface tolerance and finish of a machined part. A fillet radius is a rounded corner between two flat surfaces. A fillet radius that is too small can result in a rough surface, while a fillet radius that is too large can weaken the part.

In this scenario, a 1/4 inch diameter mill is being used, so the best surface tolerance and finish would be achieved if the fillet radius is greater than 0.125 inch, but less than 0.25 inch. This will ensure that the part is not weakened and the surface is smooth. The exact value of the fillet radius will depend on the specific requirements of the machining process.

x * 2a - b = 3x + 3a - 2 * 2a + 2b

Combining like terms:

x * 2a - b = 3x + 3a - 4a + 2b

x * 2a - b = 3x - a + 2b

Now, we can isolate x on one side of the equation:

x * 2a - 3x = a - b + 2b

x * 2a - 3x = a + b

Multiplying both sides by -1:

-x * 2a + 3x = -a - b

Adding 2a to both sides:

x * 2a + 3x + 2a = -a - b + 2a

Combining like terms:

x * 2a + 3x + 2a = -a + 2a

x * 2a + 3x + 2a = 2a

Finally, collecting all x terms on one side:

x * (2a + 3) = 2a

Dividing both sides by (2a + 3):

x = 2a / (2a + 3)

The value of x for the expression x 2a-b=3(x a)-2(2a-b) is x = 2a / (2a + 3).

help me pass alegbra class. the second screenshot is question 6.

Answers

The linear system of equations in the question are resolved as follows;

Question 4

The true statements are;

The point satisfies both equation 1 and 2The point is a solution to the system

Question 6

Solution: (1.5, -1.375)

What is a linear system of equation?

A linear system consists of two or more linear equations that operate simultaneously.

Question 4;

The system of equations is presented as follows;

Equation 1: 10·x - 2·y = 15

Equation 2: 4·x + y = 6

Plugging in the values of x = 1.5, y = 0, we get;

10 × 1.5 - 2 × 0 = 15

4 × 1.5 + 0 = 6

The point (1.5, 0), satisfies both equations in the system of equations, therefore, the point (1.5, 0) is a solution of the system of equations.

The true statements are therefore;

The point satisfies both equation 1 and 2The point is a solution of the system

Question 6;

The linear system of equation is presented as follows;

-4·x - 8·y = 5

x = 4·y + 7

The substitution method can be used by plugging in the value of x = 4·y + 7, in equation (1) as follows;

-4·x - 8·y = 5

-4·(4·y + 7) - 8·y = -24·y - 28 = 5

Adding 28 to both sides, we get;

-24·y - 28 + 28 = 5 + 28

-24·y + 0 = 5 + 28 = 33

-24·y = 33

y = 33/(-24) = -11/8

y = -11/8 = -1.375

x = 4 × (-11/8) + 7

x = -11/2 + 7 = (-11 + 14)/2 = 3/2

x = 3/2 = 1.5

Solution: (1.5, -1.375)

flip a coin. if you have flipped t tails, you need to flip t 1 consecutive heads to win the game. what is the probability to win the game?

Answers

The probability of winning the game, given t tails, is equal to [tex]0.5^t[/tex] .It's important to note that the outcome of each flip is independent.

The probability of winning the game in which you have flipped t tails and need to flip t consecutive heads can be calculated as follows:

Each flip of the coin has a probability of 0.5 of landing heads and 0.5 of landing tails. So, for the first flip, the probability of flipping a head is 0.5. For the second flip, the probability of flipping two heads in a row is

[tex]0.5 * 0.5 = 0.25[/tex]

For the third flip, the probability of flipping three heads in a row is

[tex]0.5 * 0.5 * 0.5 = 0.125[/tex]  , and so on.

Therefore, the probability of winning the game, given t tails, is equal to 0.5^t. For example, if you have flipped 2 tails, the probability of winning the game by flipping 2 consecutive heads is

[tex]0.5 * 0.5 = 0.25.[/tex]

It's important to note that the outcome of each flip is independent, so the probability of winning the game given t tails is constant regardless of the number of tails flipped prior to the current flip.

how many turning points does -3x^{3} 2 have

Answers

The polynomial -3x^3 + 2 has only one turning point.

A turning point is a point on a curve where the curve changes direction, either from going up to going down or vice versa. In other words, it is a point where the first derivative of the curve changes sign.

For the polynomial -3x^3 + 2, the first derivative is given by:

d/dx (-3x^3 + 2) = -9x^2

Since the first derivative is a monotonically decreasing function (that is, its slope is always negative), the polynomial -3x^3 + 2 has only one turning point.

Slope of first derivative

d²(-3x^3 + 2)/dx² = -18x

pls help Use your response to question 1 to write a recursive definition for the amount of medication in Aldi’s bloodstream after each dose of medication. Is your definition arithmetic, geometric, or neither? Explain.

Answers

The sequence is neither arithmetic nor geometric.

What does mathematical sequence mean?

Informally, a sequence in mathematics is a list of items that are in some order (or events). It possesses members, much like a set (also called elements, or terms). The length of the series is the number of ordered elements in the sequence, which could be unlimited.

Also, Arithmetic sequences, geometric sequences, quadratic sequences, and special sequences are the four primary categories of distinct sequences you need to be familiar with.

Squares, rectangles, circles, cones, cubes, and other shapes that can be created using geometry are known as geometric forms. In structural, civil, and architectural engineering, geometric forms are frequently used.

How to identify the type of sequence ?

The sequence in mathematics is the order of value of items or events. Usually, it contains a number or a series of numbers with a length of series that can be unlimited.

If the sequence has common differences from one value to another it can be considered as an arithmetic sequence, for example, 2,4,6,8. If the sequence has common ratios from one value to another it can be considered as a geometric sequence, for example, 2,4,8,16.

Since the response in question 1 doesn't have either common differences or common ratios, so it is neither arithmetic nor geometric.

(exercise 2: find the critical points of the gompertz equation (1). (is y = 0 a critical point? does it solve the algebraic equation you get?).dy = ry In(K/y

Answers

y = k asymptotically stable critical point because f'(k) < 0 and f'(0) > 0. So y = 0 is an an asymptotically unstable critical point.

The Gompetz equation is dy/dt = ry In(K/y).

In order to find critical points equate dy/dt equal to zero

dy/dt = 0

ry In(k/y) = 0

Here, k and r are constants

y In(k/y) = 0

y = 0

In (k/y) = 0

Eliminating In

k/y = e^0

k/y = 1

Multiply by y on both side, we get

k = y

y = 0 and y = k

The critical points are 0 and k

Since zero is a critical point

dy/dt = f(y)

dy/dt = ry In(k/y)

Differentiation on both side

f'(y) = ry In(k/y) - ry × y/k × k/[tex]y^2[/tex]

f'(y) = r In(k/y) - r

f'(k) = r In(k/k) - r

f'(x) = -r < 0

So that, y = k asymptotically stable critical point because f'(k) < 0

f'(0) > 0

That means y=0 is asymptotically unstable critical point.
