Answer:
Question A is D and Question B is B
Answer:
$0.41
Step-by-step explanation:
4.92 ÷ 12 = .41 (Look at drawing)
Answer:
9 in approx
Step-by-step explanation:
Step one:
given data
the shape of the satellite dish takes the form of a paraboloid.
the diameter of the dish is 38in wide
and 10 inches deep.
step two:
The expression for the paraboloid is

where y is the vertical axis of the paraboloid
a is vertex to focus.
and x is the radius of the dish
x= 38/2= 19in
substituting we have

divide both sides by 40

vertex to focus= 9 in approx
Answer:
Step-by-step explanation:
Plug each value of x into the equation and solve for the corresponding y value.
When x = -1, y = (-1)²-2(-1) = 3
When x = 0, y = 0² - 2(0) = 0
You can finish from here.
