Answer:
27 pi
Step-by-step explanation:
First find the area of a circle
A = pi r^2
A = pi ^^2
36 pi
We know this is 3/4 of a circle so multiply the area by 3/4
3/4 * 36 pi
27 pi
Answer:
$406.40
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.5%/100 = 0.015 per year.
Solving our equation:
A = 320(1 + (0.015 × 18)) = 406.4
A = $406.40

Problem 4
Like the three earlier problems, we'll place the kicker at the origin and have her kick to the right. The two roots in this case are x = 0 and x = 20 to represent when the ball is on the ground.
This leads to the factors x and x-20 and the equation 
We'll plug in (x,y) = (10,28) which is the vertex point. The 10 is the midpoint of 0 and 20 mentioned earlier.
Let's solve for 'a'.

This then leads us to:

The equation is in the form

Problem 5
The same set up applies as before.
This time we have the roots x = 0 and x = 100 to lead to the factors x and x-100. We have the equation 
We'll use the vertex point (50,12) to find 'a'.

Then we can find the standard form

Answer:
(1,3), or option 1
Step-by-step explanation:
The formula for a 90 degree clockwise rotation is (x,y)------>(y,-x). In this case it started out as (-3, 1). Using the formula you get (1,-3(-1)), which is equal to (1,3). Hence option 1 is correct
