A field is a rectangle with a perimeter of 1260 feet. The length is 100 feet more than width. Find the width and length of the r
lyudmila [28]

To solve this problem you must apply the proccedure shown below:

1. The formula for calculate the perimeter of a rectangle is:

P=2L+2W

Where L is the length and W is the width.

2. The length is 100ft more than the width, therefore:

L=W+100

3. Substitute values into the formula for calculate the perimeter and solve for the width:

1260=2(W+100)+2W\\ W=265ft

3. Then, the length is:

L=265ft+100ft\\ L=365ft

The answer is: The length is 365ft and the width is 265ft

The height of a punted football can be modeled by the function: f(x) = -.0079 x2 + 1.8x + 1.5. In this equation, f(x) is the hei
mars1129 [50]

Answer:

Step-by-step explanation:

The function used to represent the height of a punted football can be modeled as

f(x) = -.0079x² + 1.8x + 1.5

Where f(x) is the height in feet, and x is the horizontal distance, also in feet.

a) when the ball was punted, x = 0, therefore, the height of the punted ball would be

f(x) = -.0079(0)² + 1.8(0) + 1.5

f(x) = 1.5 feet

The height is 1.5 feet

b) The equation is a quadratic equation. The plot of this equation on a graph would give a parabola whose vertex would be equal to the maximum height reached by the punted ball.

The vertex of the parabola is calculated as follows,

Vertex = -b/2a

From the equation,

a = - 0.0079

b = 1.8

Vertex = - - 1.8/0.0079 = 227.84 feet

So the maximum height of the punt is 227.84 feet
