Answer:
Time, t = 3.125 s
Step-by-step explanation:
The height attained by the ball after it was kicked is given by as a function of time t as :
It is required to find the time until which the ball hits the ground. At that point, h(t) = 0
So,
So, 3.125 seconds before the ball hit the ground.

a = ( 0 , 7 ) & b = ( 3 , 1 )
First need to find the slope using the following equation :
_________________________________
We have following equation to find the point-slope form of the linear functions using the slope and one of the through points .
I choose point (( a )) to put in the equation.
Add sides 7
This the slope-intercept form .

Angle 1 is a "corresponding angle" with respect to the one marked 155°, so it has the same measure. The measure of angle 1 is ...
... 155°
Answer is numbers 10, 30, 70, 90
The 4 numbers must be different and added up and divided by 4 must equal 50.
Four such numbers are 10, 30, 70, 90
We all know that Average = Sum / total of numbers in sum
Addition of these different 4 numbers = 200.
Average = 200 / 4 = 50, the required average.
Problem solved!
