Answer:
2/17
Step-by-step explanation:
Given, , to find the difference, first look for the common denominator of both fractions.
Common denominator of both fractions is 17.
Divide the common denominator by the denominator of each fraction, then multiply the result by its numerator and solve as follows:
The answer is 2/17
= 2/17
Answer:
- 112 ft
- 3 - 7 seconds interval
Step-by-step explanation:
<u>Given function:</u>
- f(t) = -16t² + 96t + 112
<u>The height of the platform is the y-intercept, when t = 0:</u>
- f(0) = - 16*0 + 96*0 + 112 = 112 ft
The ball's height is decreasing once it reaches the maximum, which is at vertex.
<u>The vertex is at x = -b/2a:</u>
- t = - 96/ - 32 = 3
<u>The ball hits the ground when f(t) = 0:</u>
- - 16t² + 96t + 112 = 0
- t² - 6t - 7 = 0
- (t - 7)(t + 1) = 0
- t = 7 (positive root)
The interval is between 3 seconds and 7 seconds
