21÷3=7

21-14=7

21÷7=3

Step-by-step explanation:

The missing values are 5, 32, 3, 14, and 3 after using the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

8⋅______=40

8+______=40

21÷______=7

21−______=7

21⋅______=7

We can use the arithmetic operation to find the unknown values:

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56 etc. are the numbers.

8x5  = 40

8 + 32 = 40

21 ÷ 3 = 7

21 - 14 = 7

21 ÷ 3 = 7

Thus, the missing values are 5, 32, 3, 14, and 3 after using the arithmetic operation.

Answer:

k(t) =  (sin3, cos3, 2) + [(t - 1)(cos3, -3sin3, 7)]

Step-by-step explanation:

For a path r(t), the general equation k(t) of its tangent line at a specified point r(t₀) is given by;

k(t) = r(t₀) + r'(t₀) [t - t₀]            -----------------(i)

Where

r'(t) is the first derivative of the path r(t) at a given value of t.

From the question:

r(t) =  (sin3t, cos3t, 2[tex]t^{7/2}[/tex]) and t₀ = 1

=> r(1) = (sin3, cos3, 2) at t₀ = 1

Find the first derivative component-wise of r(t) to get r'(t)

∴ r'(t) = (cos3t, -3sin3t, 7[tex]t^{5/2}[/tex])

=>r'(1) = (cos3, -3sin3, 7)

Now, at t₀ = 1, equation (i) becomes;

k(t) = r(1) + [ r'(1) (t-1)]    [substitute the necessary values]

k(t) =  (sin3, cos3, 2) + [(t - 1)(cos3, -3sin3, 7)]

Answer: (x+-0.5)²=0

Step-by-step explanation:

4x²-4x+1=0

(2x-1)²=0 ⇔ completing the square

--------------------------------------------

since the question asked for the x should be 1, then we should divide 2x by 2 so to get rid of the 2 in front of the x.

this will change the original equation into: (x+(-0.5))²=0

------------------------------------------------------------------------------------------------------------

You can also directly divide 4 from 4x²-4x+1=0 to get rid off the terms in front of x.

x²-x+0.25=0

(x-0.5)²=0

(x+(-0.5))²=0

(6, 0) is located on the x-axis

Explanation:

For a point to be on the x-axis, its y-value must equal 0. (6, 0) has an x-value of 6 and a y-value of 0.

"(0, 5) is located at the origin" is not true because the origin is at (0, 0).

"(0, 5) is located on the x-axis" is not true because its y-value is 5, not 0.

"(6, 0) is located at the origin" is not true because the origin is at (0, 0).

The (6, 0) is located on the x-axis option (C) is correct because the y-coordinate is zero on the x-axis.

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

It is given that:

The points are (6, 0) and (0, 5).

After plotting on the coordinate plane,

For a point to be on the x-axis, its y-value must equal 0. (6, 0) has an x-value of 6 and a y-value of 0.

"(6, 0) is located at the origin" is not true because the origin is at (0, 0).

Thus, the (6, 0) is located on the x-axis option (C) is correct because the y-coordinate is zero on the x-axis.

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Step-by-step explanation:

The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side. hope this helps you :)

GIven that:

The set is :  {l, 2, 3, 4.5.6}

To Prove that:

If four numbers are to be chosen , at least one pair of the selected numbers must add up to 7

From the data set given, this set has three pairs of number which can add up to 7. These are:

{1, 6}  i.e 1 + 6 = 7

{2,5}  i.e  2+ 5 = 7

{3,4}  i.e  3 + 4 = 7

So, if four number are chosen from the set that contains six numbers, then that the possibility for such to occur is either by selecting two pairs out of the three pairs or one pair and two numbers.

Thus, in both cases, at least one pair of the selected numbers must add up to 7.

Step-by-step explanation:

2(1500mL + 375mL + 1L)

=2(1875mL + 1L)

=2(1.875L + 1L)

=2(2.875)

=5.75

The recipe will yield 5.75 liters (L) of punch when doubled.

To find the total volume of punch that the recipe will yield if doubled, we need to add the amounts of each ingredient and then multiply by 2.

Original recipe:

Fruit punch: 1,500 mL

Pineapple juice: 375 mL

Ginger ale: 1,000 mL (since 1 L = 1,000 mL)

Total volume of punch in the original recipe:

= 1,500 mL + 375 mL + 1,000 mL

= 2,875 mL

Now, if we double the recipe, we need to multiply the total volume by 2:

Total volume of punch when doubled = 2×2,875 mL

= 5,750 mL

To convert this to liters (L), we divide by 1,000 since 1 liter is equal to 1,000 mL:

Total volume of punch when doubled = 5,750 mL / 1,000

= 5.75 L

Hence, the recipe will yield 5.75 liters (L) of punch when doubled.

Step-by-step explanation:

in the state of Texas, about 3/100 of the population lives in the city Fort Wroth.

Let the population of the state of texas = X

Fort wroth population= 3/100(x)

the population of Huston, Texas, is about 3 times the population of Fort Worth, Texas. = 3*(3/100(x))

the population of Huston, Texas, is about 3 times the population of Fort Worth, Texas. =9/100(x)

The fraction of the population of Texas that lives in Huston is 9/100x.

Let the population of Texas be represented by x.

Since the state of Texas is about 3/100 of the population lives in the city Fort Wroth and the population of Huston, Texas, is about 3 times the population of Fort Worth, Texas, then the fraction of the population of Texas lives in Huston will be:

= 3/100 × 3 × x

Answer:

Explained below.

Step-by-step explanation:

At the start of every month the price of gas started out at 100¢/gallon.

Then every day since, it has gone up 2¢/gallon.

The variables are denoted as follows:

d = the date

g = price of a gallon of gas

c = total price required to fill up my car, in cents.

(a)

The function that gives the price of gas on any given day of the month is:

g (d) = 100 + 2(d - 1)

The (d - 1) represent the number of times the price has gone up by 2¢/gallon.

(b)

The function that tells how much money it takes to fill up my car, as a function of the price of a gallon of gas is:

c (g) = 10 × g

Since the car takes 10 gallons of gas.

(c)

The composite function that gives the cost of filling up my car on any given day of the month is:

c (g (d)) = 10 × g (d)

            = 10 [100 + 2(d - 1)]

c (g (d)) = 1000 + 20 (d - 1)

(d)

On the 11th day the price of gas has increased by 2¢/gallon for the past 10 days.

Compute the total price it takes to fill up my car on the 11th of the month as follows:

c (g (d)) = 1000 + 20 (d - 1)

c (g (11)) = 1000 + 20 (11 - 1)

             = 1000 + (20 × 20)

             = 1000 + 400

             = 1400¢

Thus, the it takes to fill up my car on the 11th of the month is 1400¢.

(e)

The total price to fill the car on the nth day is 1040¢.

Compute the value of n as follows:

      c (g (d)) = 1000 + 20 (d - 1)

          1040 = 1000 + 20 (n - 1)

1040 - 1000 = 20 (n - 1)

              40 = 20 (n - 1)

          (n - 1) = 2

                 n = 3

Thus, the day on which it cost 1,040¢ to fill up the car is the 3rd day.

Answer:   2

Step-by-step explanation:

You only need to evaluate at the limit point.

f(x) = 4 - x  ; x ≠ 2

Consider the solution if x = 2 (because the limit is x → 2)

                                          f(2) = 4 - (2)

                                                =   2

We know that f(x) = 0  ; x = 2

                                         f(2) = 0

but we are looking for the y- value it approaches - not the y-value it is.

Look at the graph.  You will see that as x gets closer and closer to 2, the y-value gets closer and closer to 2.  This is the limit.

Given, a particle moving on the x-axis. Its position is:

Let's assume unit of x is m.

For t= 0,

For t = 1,

a) Velocity at time t=1

Velocity = displacement/time = (-6- 4)/1 = - 10 m/s as it moves to the left

b) Speed at time t = 1

Speed = distance/time = (4 + |6|)/1 = 10 m/s

c) Acceleration at t = 1

Acceleration is rate of change of velocity.

It took 1 sec to change velocity from 0 to - 10 m/s

So acceleration is:

A: The probability of a number rolling less than 7 is 100% or 1 because a dice only has numbers 1,2,3,4,5, and 6. 1,2,3,4,5, and 6 are all less than 7 so you are guaranteed to roll a number less than 7.

B: The probability of a number rolling more than 7 is 0% or 0 because a dice only has numbers 1,2,3,4,5, and 6. 1,2,3,4,5, and 6 are all less than 7 so it's not possible to roll a number more than 7.

C: The probability of a number rolling to be a multiple of three is 33.33(repeating)% or 1/3. Out of 1,2,3,4,5, and 6, the multiples of 3 are, 3 and 6. 3 and 6 is two numbers out of six numbers. 2 out of 6 simplifies to 1 out of 3.

D: The probability of a number rolling to be less than 4 is 50% of 1/2. Out of the numbers, 1,2,3,4,5, and 6, only 1,2, and 3 are less than 4. 1,2, and 3 is three numbers out of six numbers. 3 out of 6 simplifies to 1 out of 2.

E: The probability of a number rolling to be an even number greater than 4 is 0.166(repeating) or 1/6. Out of the numbers, 1,2,3,4,5, and 6, 2,4, and 6 are even numbers. Out of 2,4, and 6, only 6 is greater than 4. 4 is one number out of 1,2,3,4,5, and 6 (six numbers).

F: The probability of a number rolling to be a number not less than 3 is 50% or 1/2. "Not less than" actually means greater than. In the numbers, 1,2,3,4,5, and 6, only 4,5, and 6 are greater than 3. 4,5, and 6 are three numbers. 3 out of 6 simplifies to 1 out of 2.

The value is [tex]P (I | L ) = 0.63[/tex]

The probability has increased

Step-by-step explanation:

From the question we are told that

   The percentage that are from outside the country is  [tex]P(O) = 0.70[/tex]

    The  percentage that logs on everyday is  [tex]P(L) = 0.60[/tex]

    The  percentage that logs on everyday that are from the inside the country is     [tex]P(L | I) = 0.80[/tex]

Generally using Bayes' Rule the probability that a person is from the country given that he logs on the website every day is mathematically represented as

     [tex]P (I | L ) = \frac{P(I)* P(L|I)}{ P(O) *P(L|O) + P(I) *P(L|I) }[/tex]

Where  [tex]P(I)[/tex] is the percentage that are from inside that country which is mathematically represented as

       [tex]P(I) = 1 - P(O)[/tex]

      [tex]P(I) = 1 - 0.70[/tex]

      [tex]P(I) = 0.30[/tex]

And [tex]P(L| O)[/tex] is  percentage that logs on everyday that are from the outside  the country which is evaluated as

      [tex]P(L| O) = 1- P(L| I)[/tex]

       [tex]P(L| O) = 1- 0.80[/tex]

       [tex]P(L| O) = 0.20[/tex]

[tex]P (I | L ) = \frac{ 0.3* 0.80 }{ 0.7 *0.20 + 0.3 * 0.8 }[/tex]    

[tex]P (I | L ) = 0.63[/tex]

Given that the percentage that are from inside that country is  [tex]P(I) = 0.30[/tex]

and that the probability that a person is from the country given that he logs on the website every day is  [tex]P (I | L ) = 0.63[/tex]

We see that the additional information increased the probability
