xxMikexx [17]

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of amount of pears picked by Kim.

Solution:

We know that,

$\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100$

$\%\text{ increase}=\dfrac{287-250}{250}\times 100$

$\%\text{ increase}=\dfrac{37}{25}\times 10$

$\%\text{ increase}=\dfrac{370}{25}$

$\%\text{ increase}=14.8$

Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.

Answer:

Average rate of change: $-3$

Step-by-step explanation:

Remember:

The average rate of change of a function over an interval $[a,b]$ is $\frac{f(b)-f(a)}{b-a}$

Given:

$[a,b]=[1,7]$

$f(b)=f(7)$

$f(a)=f(1)$

Calculation:

$f(b)=f(7)=-(7)^2+5(7)+14=-49+35+14=-49+49=0$

$f(a)=f(1)=-(1)^2+5(1)+14=-1+5+14=4+14=18$

$\frac{f(b)-f(a)}{b-a}=\frac{0-18}{7-1}=\frac{-18}{6}=-3$

Therefore, the average rate of change of the function $g(x)=-x^2+5x+14$ over the interval $1\leq x\leq7$ is $-3$ .

Petra jogs 5 miles in 40 minutes. At this rate, how long would it take her to jog 7 miles?

Wittaler [7]

(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min

At the same rate, it would take Petra 56 minutes to jog 7 miles.
