At the skateboard park, the hot new attraction is the U-Dip, a cement structure embedded into the ground. The cross-sectional vi

ew of the U-Dip is a parabola that dips 15 feet below the ground. The width at ground level, its widest part is 40 feet across. Sketch the cross-sectional view of the U-Dip, and find an equation of the parabola that models it.

valkas [14]

Answer:

\boxed{\sf{a

Step-by-step explanation:

You only need to isolate the term a to solve this problem.

Add by 3 from both sides.

\sf{\dfrac{a}{7}-3+3

Solve.

0+3=3

a/7<3

Multiply by 7 from both sides.

\sf{\dfrac{7a}{7}

Solve.

3*7=21

<u>a<21</u>

As a result, the solution is a<21, which is our answer.

Step-by-step explanation:

In hours, the total time is ...

... 1/10 + 1/5 + 1/2 = 1/10 + 2/10 + 5/10

... = (1+2+5)/10 = 8/10

... = 4/5

1. Homer has an idea for a new donut shop. He wants to design the donut shop so that the rectangular
Tju [1.3M]

Solving a <em>system of equations</em>, it is found that since the <u>quadratic equation has two positive roots</u>, they can be the values of the length and the width, and the design is possible.

The perimeter of a <u>rectangle of length l and width w</u> is given by:

P = 2(l + w)

The area is:

A = lw

In this problem, perimeter of 63.5 m, hence:

2l + 2w = 63.5

2l = 63.5 - 2w

l = 31.75 - w

Area of 225 m², hence:

lw = 225

(31.75 - w)(w) = 225

w^2 - 31.75w + 225 = 0

Which is a quadratic equation with coefficients a = 1, b = -31.75, c = 225.

Then:

\Delta = b^2 - 4ac = (-31.75)^2 - 4(1)(225) = 108.0625

w_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{31.75 + \sqrt{108.0625}}{2} = 21.1

w_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{31.75 - \sqrt{108.0625}}{2} = 10.68

Since the <u>quadratic equation has two positive roots</u>, they can be the values of the length and the width, and the design is possible.
