Answer:
the 2 one is a linear and the rest are non
Your answer is 2 because 11 times 2 is 22
(x-1)(x+1) = 0
x = 1 or x = -1
Ans : -1 and 1
-5 -4 -3 -2 -1 0 1 2 3 4 5

It would be the second one because to make a equation perpendicular, you have to flip the fraction (and if it was a whole number like 6 it would become 1/6) and then make it negative.
So your new equation would be y=-6/7x+4
Answer:
After 1 second, the ball will reach a maximum height of 16 feet
Step-by-step explanation:
The height of the ball after t seconds: h(t) = -16t^2 + 32t
The graph of this quadratic function is parabola which opens downwards. The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola
t = -b/2a = -(32)/2(-16) = -32/-32 = 1 second
then
h(t) = -16(1)^2 + 32(1) = -16 + 32 = 16
After 1 second, the ball will reach a maximum height of 16 feet
