Answer:
Step-by-step explanation:
To solve this problem, we can use the area of a circle formula as shown below:
<em>A = area</em>
<em>r = radius</em>
<em />
First we need to find the radius.
The radius is half of the diameter. For this problem, the radius is going to be 3.
Now, plug the values into the equation:
The window's area is
Answer:
(-1,-7)
Step-by-step explanation:
Substitute 2x-5 (from the first equation) as the y-value for the second equation, so you have something that looks like this:
2x-5 = -2x-9
Add 2x to both sides: 4x-5 = -9
Add 5 to both sides 4x = -4
Divide both sides by 4: x = -1
Substitute -1 for x in either equation (you'll get the same y-value)

Answer:
1) vertex:-1
axis of symmetry:-1
y-intercept (0,-10)
x-intercepts (-3.449, 0) and (1.449, 0)
2) vertex: -1
axis of symmetry: -1
y-intercept (0,-15)
x-intercepts (3, 0) and (-5, 0)
