A.) Jennyfer threw the ball higher because her maximum height is 19.12 while Aiden's maximum is 15.04

B.) Aiden because his initial height was 6 feet while Jennyfer's was an initial height of 5 feet

C.) Jennyfer because her v value is 30, while Aiden's is only 24

D.) Aiden's because his max height time was .75, which you can multiply by 2 in order to get 1.5. Jennyfer's flight time is 1.88.

Step-by-step explanation:

Jennyfer's maximum height can be found using the following steps:

$t=\frac{-30}{-32} =.94\\\\-16(.94)^{2} +30(.94)+5\\-16(.88) + 28.20 + 5\\-14.08 + 33.20\\=19.12\\\\(.94, 19.12)$

Aiden's maximum height can be found using the following steps:

$t = \frac{-24}{-32} =.75\\\\-16(.75)^2 +24(.75)+6\\-16(.56) +18+6\\-8.96 + 24\\=15.04\\\\(.75 , 15.04)$

Goodness, that took a while to type.
