Let's call the two numbers x and 5x. We know that their difference is 1016:

5x - x = 1016

Expanding and solving for x:

4x = 1016

x = 254

So, the two numbers are 254 and 5 * 254 = 1270. These are the two numbers that have a difference of 1016 and satisfy the given condition.

Step-by-step explanation:

Answer:

1+5x=1016

Step-by-step explanation:

The nth term in the given AP is given by aₙ = 125000n - 124990 and the nth term in the given GP is given by aₙ = 5×4ⁿ/2

An arithmetic sequence has a constant difference between each consecutive pair of terms. This is similar to the linear functions that have the form y=mx+b. A geometric sequence has a constant ratio between each pair of consecutive terms. This would create the effect of a constant multiplier.

Given that, an arithmetic sequence has a common difference of 125,000. A geometric sequence has a common ratio of 4. In both sequences, a(1) = 10.  We asked to compare the sequences,

The formula for AP =

aₙ = a + (n-1)d, d = common difference, a = first term, n = number of terms and aₙ = nth term

The formula for GP =

aₙ = arⁿ⁻¹, r = common ratio, a = first term, n = number of terms and aₙ = nth term

The common difference and first term are, 125000 and 10 respectively,

aₙ = 10 + (n-1)125000

aₙ = 10+1245000n-125000

aₙ = 125000n - 124990

Therefore, nth term in the given AP is given by aₙ = 125000n - 124990

The common ratio and the first term are, 4 and 10 respectively,

aₙ = 10×4ⁿ⁻¹

aₙ = 10×4ⁿ / 4

aₙ = 5×4ⁿ/2

Therefore, nth term in the given GP is given by aₙ = 5×4ⁿ/2

In the AP, nth term will be multiplied to 125000 and the product will be subtracted from 124990, and GP nth term will increase by product of 2.5 and 4ⁿ,

Hence, the nth term in the given AP is given by aₙ = 125000n - 124990 and the nth term in the given GP is given by aₙ = 5×4ⁿ/2

Table A of conditional percentages answers the question of whether the region where one lives affects whether or not one has health insurance.

Table A is the appropriate table of conditional percentages to discover if one's region of residence influences if they have health insurance.

Table A provides the overall percentage of individuals who are insured and uninsured in each region of the country. It gives a clear picture of the proportion of people in each region who have health insurance coverage. The data in this table allows us to compare the percentage of uninsured individuals across different regions.

In contrast, Table B provides the percentage of uninsured individuals among the total number of insured and uninsured individuals in each region. This type of table does not give us a clear understanding of the overall proportion of insured and uninsured individuals in each region.

Table C provides the percentage of uninsured individuals among the total population in each region. However, it does not provide a clear picture of the proportion of insured individuals in each region, which is crucial information to determine if the region where one lives affects whether or not one has health insurance.

Step-by-step explanation:

To determine the missing values in the Venn diagram, we can use the information from the problem to set up a system of equations. Let's assign variables to each section of the diagram:

X = number of students who play tennis only

Y = number of students who play soccer only

Z = number of students who play volleyball only

W = number of students who play tennis and soccer only

y = number of students who play tennis and volleyball only

Using the information from the problem, we can set up the following equations:

X + W + 3 = 21 (21 students play tennis)

Y + W + 4 = 16 (16 students play soccer)

Z + y + 5 = 19 (19 students play volleyball)

W + 3 = 3 (3 students play soccer and tennis)

y + 5 = 5 (5 students play volleyball and tennis)

Solving for one variable in terms of the others, we can substitute into the other equations:

X = 21 - W - 3

Y = 16 - W - 4

Z = 19 - y - 5

Substituting into the equation for W, we find:

W + 3 = 3

W = 0

Substituting W = 0 into the equations for X and Y:

X = 21 - 0 - 3 = 18

Y = 16 - 0 - 4 = 12

Finally, we can substitute X, Y, and W into the equation for Z to find:

Z = 19 - y - 5

Z = 19 - 5 - 5 = 9

So the missing values in the Venn diagram are:

Soccer: 12 students

Volleyball: 9 students

Tennis: 18 students

Soccer & Tennis: 0 students

Volleyball & Tennis: 5 students

Volleyball & Soccer: 4 students

Note that the number of students who play none of the three sports is not explicitly stated in the problem, but it can be calculated as:

13 = total number of students - (X + Y + Z + W + y)

13 = total number of students - (18 + 12 + 9 + 0 + 5)

13 = total number of students - 44

So there are 57 total middle school students

The equation be x²(x + y)³ - 2xy²(x + y)² then the factorization be x(x + y)²(x - y)(x + 2y).

In mathematics, the term "factorization" or "factoring" refers to the splitting apart or "factoring" of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, which when multiplied together yield the original number, matrix, etc.

Factoring is a useful skill in real life. Examples of typical uses include splitting something into equal portions, exchanging money, comparing costs, understanding time, and performing calculations while traveling.

Let the equation be x²(x + y)³ - 2xy²(x + y)²

Factor out common term [tex]$x(x+y)^2= x(x+y)^2\left(x(x+y)-2 y^2\right)$[/tex]

[tex]$=x(x+y)^2\left(x(x+y)-2 y^2\right)$$[/tex]

Expand [tex]$x(x+y)-2 y^2= x^2+x y-2 y^2$[/tex]

simplifying the above equation, we get

[tex]$=x(x+y)^2\left(x^2+x y-2 y^2\right)$$[/tex]

Factor [tex]$x^2+x y-2 y^2=(x-y)(x+2 y)$[/tex]

Answer: 5

Step-by-step explanation:

Using order of operations, you multiply 1 and 3 first to get 3. Then you add 1 to it to get 4. Then add 4 to get 8 and subtract 3 to get 5.

Answer: 5

To solve this equation we must do PEMDAS.

Parentheses, Exponents, Multiply, Divide, Addition, Subtract.

There is no Paratheses, or Expenonets so first we divide 1 by 3.

Our equation would now be

1+3+4-3.

Next we Divide, once again there is no division so we move on to addition. The firs thing we add is 1+3, which is 4. Then 4 plus 4 which 8.

Our eqatuion would now be

8-3

Lastly we subtract 8-3 is 5

This means our answer is 5.

Consequently, when a1 is provided as 3 and the expression for the following term is a = 5an-1 + 1, the value of a5 is 2031.

An algebraic progression is when there is a continual difference between terms that follow each other in an series. For illustration, the decimal number 5, 7, 9, 11, 13, and 15 is an example of an algebraic expression with a tolerance of two. A advance with a set tolerance among any two consecutive numbers is referred to as a "arithmetic progression" (A.P.). Two types of algebraic progression are plausible: series in mathematics with a finite length A finite geometric evolution is a series with just a finite number of terms. The early, late, allowance, and frequency of terms may all be calculated using the terms in the series.

given

a1 = 3

a2 = 5 * 3 + 1 = 16

a3 = 5 * 16 + 1  = 81

a4 = 5* 81 + 1 = 406

a5 = 5* 406 + 1 = 2031

Malik's mixed number is not correct and he needs to revise it to match the correct answer of 3 3/5.

A mixed number is a combination of a whole number and a fraction. It is written as a whole number followed by a fraction.

In Malik's case, the answer he found was 3 3/5, which means three and three fifths. However, he wrote the answer as 6 3/5, which means six and three fifths.

When adding a whole number and a fraction, the final result must still be a mixed number, with the whole number part representing the sum of the whole numbers and the fraction part representing the sum of the fractions.

In this case, adding 3 and 3/5 does not result in 6 and 3/5. To see this, we need to simplify the fractional part.

Dividing 5 by 5 gives us 1, so the fractional part of 3 3/5 is 1 3/5.

Adding 3 to the whole number part and 1 3/5 to the fractional part, we get 4 1/5, not 6 3/5.

The inverse function of g(x) is:

f(x) =  (x - 2)^(2/3) + 3

Two functions are inverses if their composition is equal to the identity, then if f(x) is the inverse of our function, we must have that:

g( f(x) ) = x

Here we know that:

g(x) = (x - 3)^(3/2) + 2

Evaluating this in f(x) we should get:

g( f(x) = (f(x) - 3)^(3/2) + 2  = x

Now we can solve that for f(x).

(f(x) - 3)^(3/2) + 2  = x

( (f(x) - 3)^(3/2) =  x - 2

f(x) - 3 = (x - 2)^(2/3)

G(2, -6) is reflected in the line y=-2, the image is located at G' is (2, 2).

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given that, G(2, -6) is reflected in the line y=-2.

Since y=-2 is a horizontal line, the reflection will be vertical

So (2,-6) will reflect down 6 spaces vertically.

Step-by-step explanation:

The surface area and weight of the cylinder is 45.1805 in² and 11.107 lbs respectively.

A cylinder is a three-dimensional geometric shape that has two parallel circular bases and a curved lateral surface connecting the bases. The bases are located at opposite ends of the cylinder, and they have the same diameter. The lateral surface is a rectangle that has been bent around the circumference of the circular bases.

The height of a cylinder is the distance between the two bases, and the diameter of the bases is the distance across the circle through its center. The volume of a cylinder can be calculated by multiplying the area of one of its bases by its height. The formula for the volume of a cylinder is:

V = πr²h

where r is the radius of the circular base and h is the height of the cylinder.

Cylinders are commonly used in many real-world applications, such as in the design of pipes, cans, and other containers. They are also commonly used in mathematics and physics, where they can serve as models for objects with cylindrical symmetry, such as pipes and wires.

In summary, a cylinder is a three-dimensional shape with two parallel circular bases and a curved lateral surface connecting the bases. The height of the cylinder is the distance between the bases, and its volume can be calculated using the formula V = πr²h. Cylinders are commonly used in real-world applications and in mathematics and physics.

The following formula can be used to determine the cylinder's volume:

V = π × r² × h = π × (d/2)² × h = π × (1.35²) × 7.45 = 42.63374 in³

The following formula can be used to get the cylinder's surface area:

A = 2πr² + 2πrh = 2π × r² + 2π × r × h = 2π × (1.35²) + 2π × 1.35 × 7.45 = 45.1805 in²

The cylinder's weight can be determined using the formula below:

W = d × V = 0.259 lbs/in³ × 42.63374 in³ = 11.107 lbs.
