Answer: y=-2x+5.
Explanation: You have to use the form y=mx+b. Get the Y by itself, 5y=-10x+25. Then divide by 5 to get y by itself y=-2x+5

The area of a quarter circle is 38.465 square<br> inches. What is the quarter circle's radius?
LuckyWell [14K]

The formula for a circle's area is A=\pi r^2. We are given an area of 38.465 square inches for a quarter of it.

Multiply this value by 4 to compensate for the quarter circle.

4 \times 38.465=\pi r^2

153.86=\pi r^2

Divide both sides by pi (Note: I'm using the conventional value of 3.14)

49=r^2

Take the positive square root of both sides

7=r

The radius is 7 inches. Let me know if you have any questions, thanks!

Civil an airport, a factory, and a shopping center are at the vertices of a right triangle formed by three highways. the airport
vekshin1

Answer:

<em>The shortest possible length for the service road is 2.88 miles.</em>

Step-by-step explanation:

According to the below diagram, A, B and C are the positions of airport, shopping center and factory respectively.

Given that,  AB= 3.6 miles, BC= 4.8 miles and AC= 6.0 miles

In right triangle ABC

tan(\angle ACB)=\frac{AB}{BC} \\ \\ tan(\angle ACB)= \frac{3.6}{4.8}=0.75\\ \\ \angle ACB= tan^-^1(0.75)=36.8698.... degree

The shortest possible length for the service road from the shopping center to the highway that connects the airport and factory is BD.

That means, \triangle BCD is also a right triangle in which \angle BDC=90\°, Hypotenuse(BC)= 4.8 miles and BD is the opposite side in respect of \angle DCB or \angle ACB.

Now in right triangle BCD

Sin(\angle ACB)=\frac{BD}{BC}\\ \\ Sin(36.8698...)=\frac{BD}{4.8}\\ \\ BD=4.8*Sin(36.8698...)=2.88

So, the shortest possible length for the service road is 2.88 miles.
