Answer:
Please let me know if your quadratic is 
.
And if so your vertex is (-2,2) and your y-intercept is (0,-6)
Step-by-step explanation:
It says vertex so I'm thinking you meant . Please correct me if I'm wrong.
The vertex form of a quadratic is 
. It is called that because it tells you the vertex (h,k).
So if you compare the two forms you should see -h=2 while k=2.
-h=2 implies h=-2.
So the vertex is (h,k)=(-2,2).
To find the y-intercept, set x=0 and find y.
So the y-intercept is (0,-6).
The formula for the volume<span> of a </span>cylinder<span> is V = B h or V = π r 2 h. so pi (3.141590 times the radius SQUARED times the height.
a.) 3.14159 times 2.25 times 8 equals </span><span>56.5486677646
b.)18

Answer:
37-9=28
Step-by-step explanation:
it was 28 F then rose 9 which is 37 so 37-9 =28
Step-by-step explanation:
By angle sum property
7x-41+5x-12+2x+9 = 180
14x -44 =180
14x =224
x= 224/14
x= 16°
Answer:
46
Step-by-step explanation:
b=4 and a=7
b+6a
Substitute
4+6(7)
=4+42
=46
