[tex]54 \pi \text{ cm}^3[/tex]

=========================================================

Work Shown:

[tex]V = \pi*r^2*h\\\\V = \pi*3^2*6\\\\V = \pi*9*6\\\\V = \pi*54\\\\V = 54\pi\\\\[/tex]

This is the exact volume in terms of pi.

To find an approximation, replace pi with something like 3.14 and simplify.

The units for the volume are in cubic centimeters, which can be abbreviated to "cubic cm" or to [tex]\text{cm}^3[/tex]

Each week Raisa earns $5.25 for doing chores. After saving money for 12 weeks, Raisa spends $13.45. How much money does Raisa have left?

Answers

Answer:

$49.55

Step-by-step explanation:

She earns $5.25 every week for 12 weeks, so we multiply her weekly income by 12.

$5.25 * 12 = $63.00

Then she spends $13.45, so we deduct that from her earnings.

$63.00 - $5.25 = $49.55

That shows us that she has $49.55 left.

Step-by-step explanation:

Given the following question:

[tex]10\frac{2}{3} \times3\times6\frac{3}{8}[/tex]

In order to solve we will convert the mixed numbers into improper fractions and then solve by multiplying the numerators by the numerators and multiplying the denominators by the denominators.

[tex]10\frac{2}{3} \times3\times6\frac{3}{8}[/tex]
[tex]10\frac{2}{3} \times3[/tex]
[tex]10\frac{2}{3} =3\times10=30+2=32=\frac{32}{3}[/tex]

[tex]3=\frac{3}{1}[/tex]

[tex]\frac{32}{3} \times\frac{3}{1}[/tex]
[tex]32\times3=96[/tex]
[tex]3\times1=3[/tex]
[tex]=\frac{96}{3}[/tex]

[tex]\frac{96}{3}\times6\frac{3}{8}[/tex]
[tex]6\frac{3}{8} =8\times6=48+3=51=\frac{51}{8}[/tex]
[tex]\frac{96}{3}\times\frac{51}{8}[/tex]
[tex]96\times51=4896[/tex]
[tex]3\times8=24[/tex]
[tex]=\frac{4986}{24}[/tex]

Simplify by reducing:
[tex]=\frac{4986}{24}\div2=\frac{2493}{12}[/tex]
[tex]=\frac{2493}{12}[/tex]
[tex]\frac{2493}{12}[/tex]

Find the average rate of change of g(x)=2x2-8x from x=2 to x=5

Answers

Answer:

The average rate of change is 20.

Step-by-step explanation:

To find the answer, plug in the 2 and 5 for x.

g(2) = 2(2)^2 - 8(2)

g(2) = 16 - 16

g(2) = 0

g(5) = 2(5)^2 - 8(5)

g(5) = 100 - 40

g(5) = 60

g(5)-g(2)/5-2 = the average rate of change

60/3=20

What is the equation in point slope form of the line that passes through the point (2 , 4) and has a slope of 3?

Question 4 options:

y=3x-10


y-4=3(x-2)

Answers

Solution:

Step-1: Use point slope form.

y - y₁ = m(x - x₁)=> y - 4 = 3(x - 2)      [Option B]

Step-2: Identify the equation of the line.

New data collected on roller coasters, comparing height of the initial drop to
the speed of the coaster, found that the regression line equation is actually y 0.502x +12.250.

Answers

The regression line equation y = 0.502x +12.250 is a linear regression

The predicted speed at a drop of 100 feet is 62.45The predicted speed at a drop of 500 feet is 263.25It is unlikely that the speed of the roller coaster would reach 263.25

The predicted speed at a drop of 100 feet

The regression line equation is given as:

y = 0.502x +12.250

Substitute 100 for x

y = 0.502 * 100 +12.250

Evaluate the sum

y = 62.45

The predicted speed at a drop of 500 feet

The regression line equation is given as:

y = 0.502x +12.250

Substitute 500 for x

y = 0.502 * 500 +12.250

Evaluate the sum

y = 263.25

Step-by-step explanation:

Like a lot of algebraic manipulation associated with average rate of change, it is not difficult, but it can be tedious.

a)

  [tex]f(x+h)=2(x+h)^2-(x+h) +2 = 2(x^2 +2xh +h^2)-x -h +2\\\\\boxed{f(x+h)=2x^2-x+2+4xh-h+2h^2}[/tex]

3/4 of a number is greater than 3/16 of the same number by 81. What is 1/2 of the number?

Answers

Answer:

  72

Step-by-step explanation:

The given word description can be translated to math symbols this way, when x represents the number:

  3/4x -3/16x = 81

Multiplying by 16 gives ...

  12x -3x = 1296

  9x = 1296 . . . . . . simplify

We want to find the value of half the number, so we can divide this by 18 to get ...

  x/2 = 1296/18 = 72

Half the number is 72.

The points (-6,r) and (2,5) lie on a line with slope -1/4. Find the missing coordinate r.

Answers

Answer:

r = 7

Step-by-step explanation:

Calculate the slope using the slope formula then equate to - [tex]\frac{1}{4}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, r ) and (x₂, y₂ ) = (2, 5 )

m = [tex]\frac{5-r}{2-(-6)}[/tex] = [tex]\frac{5-r}{2+6}[/tex] = [tex]\frac{5-r}{8}[/tex] , then

[tex]\frac{5-r}{8}[/tex] = - [tex]\frac{1}{4}[/tex] ( multiply both sides by 8 to clear the fractions )

5 - r = - 2 ( subtract 5 from both sides )

- r = - 7 ( multiply both sides by - 1 )

r = 7

Answer:

[tex]\displaystyle 7[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m\\ \\ \frac{-r + 5}{6 + 2} = m \Rightarrow \frac{-r + 5}{8} \hookrightarrow -\frac{2}{8} = -\frac{1}{4} \\ \\ \boxed{7 = r}[/tex]

Which is the volume of the solid? The solid is made up of 2 cuboids. First cuboid has length as 4 unit cubes, height as 1 unit cubes and width as 2 unit cubes. Second cuboid has length as 1 unit cube, height as 3 unit cubes and width as 2 unit cubes.
A. 14 cubic units
B. 16 cubic units
C. 21 cubic units
D. 35 cubic units

Answers

Answer:

14 cubic units

Step-by-step explanation:

The Formula for Volume is

V = L x W x H

Since there are 2, you need to add the two totals together.

Cubic one:

4 x 1 x 2  =  8 (it also doesn't matter what order you put your numbers in, you will still get the same outcome. Its called the commutative property of multiplication)

Cubic Two:

1 x 3 x 2 = 6

Now just add the totals together:

6 + 8 = 14

Answer:

A) 14 cubic units

Solution:

Here, we have to find the volume of the solid which is made up of two cuboid. We know that the volume of cuboid is given by:

V = l × w × h

The volume of the solid will be equal to the sum of volume of given two cuboid

For 1st cuboid :

l = 4 unit h = 1 unit w = 2 unit

Therefore, Volume:

V = l × w × h

V = 4 × 2 × 1

V = 8 unit³

For 2nd cuboid:

l = 1 unitw = 2 unitsh = 3 units

Therefore, Volume:

V = l × w × h

V = 1 × 2 × 3

V = 6 unit ³

Now, Volume of solid :
