Answer:
The answer is 211.96
Step-by-step explanation:
First I did the semicircle, the radius is 7 so 7 x 2 = 14 and then I did
14 x 3.14 = 43.96
Then I did 12 x 14 = 168
Finally 168 + 43.96 = 211.96
Hope this helps
Answer:
An integer is a whole number, positive or negative. A rational number is a number which can be expressed as a fraction between 2 whole numbers. An integer is a rational number, because every integer can be expressed as a fraction between itself and 1, both whole numbers.

Answer:
y = 2(x-3)^2 -12
y = -4/9(x-2)^2 +7 bonus
Step-by-step explanation:
The vertex form of a parabola is
y = a(x-h)^2 + k where (h,k) is the vertex
y = a(x-3)^2 - 12
We have one point given (0,6)
6 = a (0-3) ^2 -12
6 = a (-3)^2 -12
6 = 9a-12
Add 12 to each side
6+12 = 9a
18 = 9a
Divide each side by 9
18/9 = 9a/9
a=2
y = 2(x-3)^2 -12
We follow the same steps for the bonus
y = a(x-2)^2 +7
Substitute the point into the equation
3 = a (-1-2)^2 +7
3 =a (-3)^2 +7
3 = 9a +7
subtract 7 from each side
3-7 = 9a +7-7
-4 = 9a
Divide by 9
-4/9 =a
y = -4/9(x-2)^2 +7
Yes, (2,0) is a solution to y<2x+4
Answer:
5
Step-by-step explanation:
Subtract the spent money to rent cost:
27-5.75=21.25
Divide the answer to the cost of each game:
21.25/4.25=5
