The best metric used for students kicking a football would be a meter.
A meter is about the height of a table. This would be a good measure for the distance when kicking a football. A football field is already divided into yards which are very similar in length to meters.
If it decreases at 4% every year, then its value becomes:
100% - 4% = 96% = 96/100 = 0.96
At the end of the 1 year its value becomes: 150*(0.96)
At the end of the 2 years its value becomes: 150*(0.96)*(0.96) = 150*(0.96)²
At the end of the 3 years its value becomes: 150*(0.96)*(0.96)*(0.96) = 150(0.96)³
So similarly at the end of 12 years, its value becomes 150*(0.96)¹²
=50*(0.96)¹² simplify with calculator.

Answer:
15. h⁻¹ (x) = 5x-6/2
16. (g.f)x = 4x^2 -2x -1
Step-by-step explanation:
15. Find Inverse of h(x) = 2x+6 /5
Let y = 2x+6/5 we need to find value of x
Multiplying both sides with 5
5y = 2x+6
Adding -6 on both sides
5y -6 = 2x
Dividing both sides by 2
5y-6/2 = x
Now replace y with x our answer will be:
h⁻¹ (x) = 5x-6/2
16. f(x) =2x-1 and g(x) = x^2 -2 find (g.f)x
(g.f)x can be written as: g(f(x))
We know f(x) = 2x-1 so, put value of f(x) into x of g(x).
Putting values we get:
(g.f)x = g(f(x))= (2x-1)^2 -2
= 4x^2 -2x +1 -2
= 4x^2 -2x -1
so, (g.f)x = 4x^2 -2x -1
Answer:
m = -1
c = 9
Step-by-step explanation:
<em>m</em> is slope, which is the coefficient of <em>x</em>
<em>c</em> is the y-int, which is the constant
