Answer:
(-1,0) (0,4) (1,0)
Step-by-step explanation:
The turning points are also called the critical points. It is where the graph changes direction.
They occur at (-1,0) (0,4) (1,0)
Total marks C needs to get = 92 x 4 = 368
Least grade (fourth quarter) = 368 - 88 - 91 - 90 = 99
I believe it would be 144 :)
ANSWER: The number is 10.
Hope this helps!!
I used the variable n as the number we needed to find. The equation was n + 8 + 12 = 3n
ANSWER
5
EXPLANATION
The equation that expresses the approximate height h, in meters, of a ball t seconds after it is launched vertically upward from the ground is

To find the time when the ball hit the ground,we equate the function to zero.

Factor to obtain;

Apply the zero product property to obtain,


t=0 or t=5.1 to the nearest tenth.
Therefore the ball hits the ground after approximately 5 seconds.
