Answer:
C = 2 π r
Step-by-step explanation:
Your answer is 2 pi/π r.
The formula of a circumference is always 2 pi r.
18 x 3.14 x 2 = 113.04
in this case radius is 18
pi is 3.14
2 is just always there when finding out circumference.
Answer:
Step-by-step explanation:
(-1, 1): You can see that a vertical line through x = -1 is the center line (axis of symmetry) of this parabolic graph. The vertex lies 1 unit above the x-axis: y = 1.
Answer:
when x= -4, y= 2
when x= 6, y =7
Step-by-step explanation:
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2
first we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4-2
then subtraction
y=2
For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps
y = 1/4 (36) - 2
y= 9-2
y= 7
