Answer:
A. The football does not reach a height of 15ft
Step-by-step explanation:
Given
Required
Determine which of the options is true
The option illustrates the height reached by the ball.
To solve this, we make use of maximum of a function
For a function f(x)
Such that:
:
i.e we first solve for 
Then substitute for x in
In our case:
First we need to solve
Then substitute for t in
By comparison:
Substitute 
for t in
This implies that the maximum height reached is 14.0625ft.
So, the option that answers the question is A because 
the answer is it is proportional
Answer:
(0,3)
y=3
x=0
Step-by-step explanation:
x+5y=15
-3x+2y=6
solve the equation
x=15-5y
-3x+2y=6
substitute the value of x into an equation
-3(15-5y)+2y=6
distribute
-45-15y+2y=6
add 15 to 2
-45-17y=6
add 45 from both sides
17y=51
divide both sides by 17
y=3
substitute the value of y into an equation
x=15-5•3
multiply 5 to 3
x=15-15
subtract
x=0
(0,3)
Formula for area of a rectangle is: A = l x w
A: Area
l: length
w: width
length of football field is 100 yards and width is 53.3 yards.
To find the area we need to multiply the length by width.
Area of football field = 100 x 53.3 = 5330 square yards (yards^2)
