The height of a baseball after being hit by a batter is given by h(t) = -16t2 + 60t + 4 (where h(t) is the height and t is the time after hitting the ball). You are asked to find the time it takes the ball to hit the
ground. After substituting zero for the height and solving using the quadratic formula, you determine
that the time is approximately -0.07 and 3.82 seconds.
5. Do both of those answers make sense?
Why?
6. What is the final solution to the problem?

11

step-by-step explanation:

32.50-7.50=25

225/25=11

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
