Answer:
mistake in the second line
Step-by-step explanation:
3(x-6)+(4x+12)-6x
3x-18+4x+12-6x
x-6
N+15=M N+M=-47 -47-15=-62 -62/2=-31 -31+-16=-47, therefore the answer is N=-31 and M=-16
Answer:
g(f(-1)) = 2
Step-by-step explanation:
f(x) = 2 + x
g(x) = 3 - x
if you need to find g(f(-1)); find f(-1) first
f(-1) = 2 + (-1) = 1
f(-1) =1; now plug this into g(1)
g(1) = 3 - 1 = 2
Answer:
(a)Time taken to reach the ground, x=6 seconds
(b)Maximum height of the arrow during its flight =101.25 feet
Step-by-step explanation:
Given the quadratic function which models the flight of the arrow:

Where:
- y represents the vertical height of the arrow, in meters; and
- x represents the time, in seconds.
(a)Positive Zero

In 6 seconds, the arrow will hit the horizontal plane, i.e. the ground.
(b)

Comparing with the vertex form:

Our vertex, (h,k)=(1.5, 101.25)
Maximum Value of y=101.25
The maximum value of y represents the maximum height of the arrow during its flight, which is 101.25 feet.
