$f(t) = -16t^{2} +48t + 100$
Average rate of change from t = 3 seconds to t = 5 seconds = $\frac{f(5)-f(3)}{5-3} = \frac{(-16( 5^{2})+48(5)+100)-(-16( 3^{2})+48(3)+100 }{2}=$ $\frac{(-16(25)+240+100)-(-16(9)+144+100)}{2} = \frac{(-400+240+100)-(-144+144+100)}{2}=$ $\frac{-60-100}{2} = \frac{-160}{2} = -80$

How much water must be evaporated from 36 ounces of a 8% salt solution to make a 9% salt solution?

topjm [15]

Answer:

4 oz of water must be evaporated

Step-by-step explanation:

If we let x represent the amount of water to be evaporated, the relation between the solutions is ...

0.08 · 36 oz = 0.09 · (36 -x) oz

0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36

x = 36· 0.01/0.09 = 36/9 = 4

4 ounces of water must be evaporated.

Let the average profit or loss in year 2006 be x millions,

The average profit for the 8-year period, is the total sum of the profits (or losses) of each year, divided by 8:

so we have:

$\displaystyle{ \frac{3.40+2.10+x+0.60+2.10+0.20+1.30+0.75}{8}=1$

$\displaystyle{\frac{10.45+x}{8}=1$

$10.45+x=8$

x=8-10.45=-2.45

Answer: the loss in 2006, was 2.45 million dollars
