Answer:
57 dollars
Step-by-step explanation:
95-40%
95 - 38 = 57 dollars.
The zeros are the values of t for which f(t) = 0.
i.e. <span>-16t^2 + 96t = 0
16</span>t^2 - 96t = 16t(t - 6)
16t = 0 or t - 6 = 0
t = 0 or t = 6
Therefore, the zeros are 0, 6
The time taken for the ball to hit the ground is the value of t when f(t) = 0.
i.e. t = 6.
Answer:51 minutes
Step-by-step explanation:
If it looks like this:
A -------------------- B

C -------------------- D
Then BC is the hypotenuse of a right triangle with sides 16 and 30. Using the Pythagorean Theorem you can solve for the length of the hypotenuse:


F(0) = 0 + 4 = 4 Because 0 < 5
F(6) = 8 Because 5 < 6 < 7
