Answer: 4 seconds
Step-by-step explanation:
Given: The function
can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get

Put h'(t)=0

Also, 
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
Answer:
127 7/9
Step-by-step explanation:
144 - 2/9
144/1 - 2/9
(144×9)−(2×1)/1×9
1296-2/9
1294/9
= 143 7/9
143 7/9 - 16
= 127 7/9
Answer:
$12
$8
Step-by-step explanation:
Amount Jatin received = (ratio of Jatin's share / sum of ratios) x amount shared
sum of ratios = 3 + 2 = 5
(3/5) x 20 = $12
Amount Arnav received = (ratio of Arnav's share / sum of ratios) x amount shared
(2/5) x 20 = $8
or
$20 - $12 = $8
