Answer:
Step-by-step explanation:
vertex is 1 units left.
y is always positive.
y=|x+1|
Positive 18, going off the assumption that the tick 2 spaces away from -1 is positive 9.
7 is the distance from school to his aunt
44/5=8.5
8.5-1.5=7
Answer:
the answer is 67.980
Step-by-step explanation:
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!
