Answer:
second option
Step-by-step explanation:
Given
+ 6x² + 5 = 0
let u = x², then
u² + 6u + 5 = 0 ← in standard form
(u + 1)(u + 5) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 1 = 0 ⇒ u = - 1
u + 5 = 0 ⇒ u = - 5
Change u back into terms of x, that is
x² = - 1 ( take the square root of both sides )
x = ± 
= ± i ( noting that = i ), and
x² = - 5 ( take the square root of both sides )
x = ± 
= ± 
= ± 
× = ± i
Solutions are x = ± i and x = ± i
Add all 3 and you get 264 then divide by 3 and you get 88
Based on the given graph, the time when the softball reaches its maximum height is about 1.8 seconds.
<h3>When is the softball at it highest?</h3>
The softball is at its maximum height at the point where the curve begins to go back down.
This means the maximum height is 50 feet.
The time when this softball reaches this height is between 1 and 2 seconds at 0.8.
The time the softball reaches its maximum height is therefore 1.8 seconds.
