first one is 42/7 = 6

11*6 = 66

second one

Answer:

Question 4

You have actual length of the stage is 42 feet and the scale drawing is 11cm: 7ft. Divide the 42 by 7 and the answer is 6. You would need 6 of the 7 ft increments to equal the total of the 42 ft stage. If you multiply one side of a ratio, then you have to multiply both sides. 11 x 6= 66!

Step-by-step explanation:

42/7 = 6

11cm x 6: 7ft x 6

66cm: 42ft

Question 5

You have an actual length of the garage is 8 1/2 inches, or 8.5 inches on the blueprint. It take 2 of the 1/2 inch segments to get 1 inch. You need 8 1/2 or 8.5 total inches. You have to multiply 8.5 by 2 to get the total number of 1/2 inch increments that you need. 8.5 x 2 = 17. This tells you that you would need 17 of the 1/2 increments to get your total blueprint length. If you multiply one side of a ratio, then you have to multiply the other side. 17 x 1 1/2 or 1.5 = 25.5

Step-by-step explanation:

1/2 inch or 0.5 inch x 2 = 1 inch

8 1/2 inches or 8.5 inches x 2 increments = 17 increments

1 1/2 ft or 1.5 ft x 17 = 25.5 ft

Which function has the greatest rate of change on the interval from x = 3 pi over 2 to x = 2π?

vodka [1.7K]

The average rate of change for the function f(x) can be calculated from the following equation
$\frac{f( x_{2})-f( x_{1} )}{ x_{2} - x_{1} }$

By applying the last formula on the given equations
(1) the first function f
from the table f(3π/2) = -2 and f(2π) = 0
∴ The average rate of f = $\frac{f(2 \pi)-f( \frac{3 \pi}{2} )}{2 \pi - \frac{3 \pi}{2} } = \frac{0-(-2)}{ \frac{\pi}{2} }= \frac{2}{ \frac{\pi}{2} } = \frac{4}{\pi}$

(2) the second function g(x)
from the graph g(3π/2) = -2 and g(2π) = 0
∴ The average rate of g = $\frac{g(2 \pi)-g( \frac{3 \pi}{2} )}{2 
\pi - \frac{3 \pi}{2} } = \frac{0-(-2)}{ \frac{\pi}{2} }= \frac{2}{ 
\frac{\pi}{2} } = \frac{4}{\pi}$

(3) the third function h(x) = 6 sin x +1
∴ h(3π/2) = 6 sin (3π/2) + 1 = 6 *(-1) + 1 = -5
 h(2π) = 6 sin (2π) + 1 = 6 * 0 + 1 = 1
∴ The average rate of h = $\frac{f(2 \pi)-f( \frac{3 \pi}{2} )}{2 
\pi - \frac{3 \pi}{2} } = \frac{1-(-5)}{ \frac{\pi}{2} }= \frac{6}{ 
\frac{\pi}{2} } = \frac{12}{\pi}$

By comparing the results, The function which has the greatest rate of change is h(x)


So, the correct answer is option C) h(x)

You started this year with $440 saved and you continue to save $11 per month.

oee [108]

11m + 440 = s
($11/ month plus your already saved $440 equals total savings)

9(1 + w) – 5w = 5 W=

RoseWind [281]

Answer:

w= -1

Step-by-step explanation:

Use PEMDAS to solve.

9(1 + w) - 5w = 5

distribute 9 to everything inside the parentheses.

9 x 1 = 9

9 x w = 9w

rewrite equation

9 + 9w - 5w = 5

combine like terms

9w - 5w = 4w

rewrite equation

9 + 4w = 5

subtract 9 from both sides

9 - 9 = 0

5 - 9 = -4

rewrite equation

4w = -4

divide by 4 on both sides to get w by itself.

4w / 4 = w

-4 / 4 = -1

Hope This Helps :)
