Answer:
C
Step-by-step explanation:
It is C
B. 84
The scale factor is 1/12 which means to get back to the actual height, you would multiply 7x12
Given:
The functions are


To find:
The value of g(f(0)).
Solution:
We have,

Putting x=0, we get


Now,
![[\because f(0)=0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%280%29%3D0%5D)
![[\because g(x)=x+6]](https://tex.z-dn.net/?f=%5B%5Cbecause%20g%28x%29%3Dx%2B6%5D)

Therefore, the value of g(f(0)) is 6 and the correct option is B.
X^2 + y^2 - x - 2*y = 0
To find both coordinates and radius we need to make this equation in circle form:
(x-a)^2 + (y-b)^2 = r^2
x^2 - 2*1/2*x + 1/4 - 1/4 + y^2 - 2*1*y + 1 - 1 = 0
Here we are adding and subtracting numbers in order to get square binomial.
(x - 1/2)^2 + (y-1)^2 = 5/4
coordinates of center are (1/2,1) and the radius is √
