miskamm [114]

Answer:

Step-by-step explanation:

$f(x) = x - 8 \\ \\ g(x) = |x + 8|$

To find (f ∘ g)(x) , substitute g(x) into f(x). That is for every x in f (x) replace it with g (x)

That's

The Ferris wheel has a radius of 70 feet. The distance between the wheel and the ground is 4 feet. The rectangular coordinate sy

Leya [2.2K]

Answer:

The equation of the circular wheel is $x^2+(y-74)^2=(70)^2$ .

Step-by-step explanation:

Given :

Radius of Ferris wheel r = 70 feet.

The distance between the wheel and the ground = 4 feet.

Also, the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel.

So the x coordinate of center of wheel must be 0 , and y coordinate = 70 + 4 = 74

Thus, Coordinates of center = (0,74)

The equation of circle is given by :-

$(x-h)^2+(y-k)^2=r^2$

Now center (h,k) = (0,74) and r = 70 , we get

$x^2+(y-74)^2=(70)^2$

Hence, the equation of the circular wheel is $x^2+(y-74)^2=(70)^2$ .
