Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>3</u></em></h2>
Step-by-step explanation:
<h2>Given,</h2>
11x - 16 = -49
=> 11x = - 49 + 16
=> 11x = -33
<em><u>=</u></em><em><u>></u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-3</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Hello :
<span>f(x) = (-1)^x
if x=3
f(3) = (-1)^3 = -1</span>
4 is 10 because as you can tell -20 + 10=-10 + 10 = 0 + 10= 10. So it would be letter c
Answer:
A. The maximum height of the ball is about 342 feet, which occurs approximately 4½ seconds after the ball is hit.
Step-by-step explanation:
The height of the ball is demonstrated by the equation:
The given equation is a quadratic equation. The maximum/minimum of a quadratic equation occurs at the vertex.
The vertex of a general quadratic equation of the form:
occurs at x =
Comparing the given equation with general equation, we get:
a = -16
b = 148
So, the maximum value will occur when t will be:
From the given options we can see that the closest to 4.625 is 4 which is given by option A.
So from here we can conclude that : The maximum height of the ball is about 342 feet, which occurs approximately 4½ seconds after the ball is hit.
