When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!
Answer:
(-4,-4)
Step-by-step explanation:
Anytime you reflect a coordinate point across the x-axis, the y-coordinate becomes its opposite and the x-coordinate stays the same.
In this coordinate: (-4,4)
Reflecting (-4,4) across the x-axis means the x-coordinate (-4) would stay the same and the y-coordinate (4) would become its opposite (-4).
The new coordinates after being reflected across the x-axis are (-4,-4).
It’s organized on which is more important and which is least important and they Wright about a subject then they put a picture to tell you about it
Answer:
4
Step-by-step explanation:
3n-2-n=6
2n-2=6
2n=8
n=4
U have some vertical angles....vertical angles are equal
5x + 2 = 3(x + 14)
5x + 2 = 3x + 42
5x - 3x = 42 - 2
2x = 40
x = 40/2
x = 20
JNM = 5x + 2.....5(20) + 2 = 102
KNL = 3(x + 14).....3(20 + 14)....3(34) = 102 <===
