it takes 5 seconds to reach a height of 40 ft. and It takes 2.5 seconds to reach maximum height.
Let h(t) represent the height of the ball at time t.
Given that the height is given by:
h(t) = -16t² + 80t + 40
1) For the ball to reach a height 0f 40 ft, h(t) = 40, hence:
40 = -16t² + 80t + 40
16t² - 80t = 0
t(t - 5) = 0
t = 0 or t = 5
Hence it takes 5 seconds to reach a height of 40 ft.
2) The maximum height is at h'(t) = 0,
h'(t) = -32t + 80
-32t + 80 = 0
32t = 80
t = 2.5
It takes 2.5 seconds to reach maximum height.

A and E are corresponding angles so A=E
Answer:
False
Step-by-step explanation:
It is infinitely many solutions
If the equations are not equal, that's when there are no solutions
Infinitely many solutions means that the 2 lines are scalar multiples of each other. They are basically over lapping lines, one of the line just has larger coefficients
EX: x + y = 2
2x + 2x = 4
*These two lines are just scalar multiples of each other. The second equation is just the first equation multiplied by 2. They are the same line.
So any point (x, y) that is on one line is also on the other (these are solutions to the system). There are an infinite amount of points on the line that satisfy the system, so there are infinitely many solutions
Solving this using elimination....
-2x - 2y = -4 (multiply the first equation by -2)
2x + 2y = 4
Now add them....
0 = 0
