The equation that models the height of the baseball is determined as H(t) = 5 + 49.64t -16(t)².
<h3>
Maximum height reached by the base ball</h3>
The maximum height reached by the baseball is calculated as follows;
H = y₀ + v₀yt + ¹/₂gt²
Assuming negative direction for upward motion
H = y₀ + v₀yt - ¹/₂gt²
0 = y₀ + vt -16(t)²
0 = 5 + 3.2v - 16(3.2)²
0 = 5 + 3.2v - 163.84
3.2v = 158.84
v = 158.84/3.2
v = 49.64
<h3>Required equation model</h3>
H(t) = 5 + 49.64t -16(t)²

Answer:
A. 5^20 x 7^40
Step-by-step explanation:
The exponent outside applies to each factor inside parentheses. The rules of exponents say ...
(a^b)^c = a^(b·c)
so, you have ...
