Darryl Dixon shoots an arrow at a zombie. The path of the arrow can be modeled with the equation y=-x^2 42x-80, where x is time in seconds and y is the height in feet. How long does it take for the arrow to reach its maximum?
We need to find time taken to reach arrow to its maximum.
The path of the arrow can be modeled with the equation [tex]y=-x^2+ 42x-80[/tex] .
Differentiating the given equation w.r.t x and equate it to zero.
[tex]\dfrac{dy}{dx}=-2x + 42 \\\\42 - 2x = 0\\\\x = 21\ seconds[/tex]
Putting value of x = 21 sec in given equation, we get :
[tex]y=-x^2+ 42x-80\\\\y = -(21)^2 + (42\times 21) - 80\\\\y = 361 \ feet[/tex]
Therefore, time taken to reach maximum height is 21 seconds.

Hi there!
[tex]\large\boxed{-40 + 20i}[/tex]
Recall the rules for the imaginary number "i":
i = √-1 i² = -1
Given:
(5i) (5i) + (5i) (4 + 3i)
Multiply:
(25i²) + 20i + 15i²
Simplify using the rule above:
25(-1) + 20i + 15(-1)
-25 + 20i - 15
-40 + 20i
a = -40
b = 20
