Answer:

  1. 63 mph
  2. 3 donut holes per kid
  3. $0.70 per pound
  4. $2.25 per km

Step-by-step explanation:

In this context, "per" and "for" mean "divided by."

  1. 630 mi/(10 h) = 63 mi/h
  2. (24 dh)/(8 kid) = 3 dh/kid
  3. $3.50/(5 lb) = $0.70 /lb
  4. $32/(14 2/9 km) = $32/(128/9 km) = $(9/4)/km = $2.25 /km

miv72 [106K]

Answer:

(1)7 (2)9 (3)6

Step-by-step explanation:

\left|\begin{array}{c|cc}X&f(X)=X^2+7\\--&-----\\2&11\\3&16\\4&23\\5&32\\6&43\end{array}\right|

(1)The average rate of change between x=2 and x=5

\dfrac{dy}{dx} =\dfrac{f(5)-f(2)}{5-2} =\dfrac{32-11}{3} =\dfrac{21}{3} =7

(2)The average rate of change between x=3 and x=6

\dfrac{dy}{dx} =\dfrac{f(6)-f(3)}{6-3} =\dfrac{43-16}{3} =\dfrac{27}{3} =9

(3)The average rate of change between x=2 and x=4

\dfrac{dy}{dx} =\dfrac{f(4)-f(2)}{4-2} =\dfrac{23-11}{2} =\dfrac{12}{2} =6

B) 20

Step-by-step explanation:

By <em>Length · Width · Height</em>

A)  (5) · (4) · (2) = 40

For part B, the length and width are the same, but the depth (height) of the water is only one foot, so we can replace the height value from the first equation with 1.

B) (5) · (4) · (1) = 20
