20x1/4=5
Think thats what you mean
Radius is half of the diameter so it's 7 for the diameter.
Answer:
The y intercept is (0,-22)
Step-by-step explanation:
The y intercept is the value when x =0
Y=5x-22
y = 5*0 -22
y = -22
The y intercept is (0,-22)
Please write x^2, not x2.
If you stretch the graph of y=x^2 vertically by a factor of 4, the resulting graph represents the quadratic function y = 4x^2. It's still a parabola, but appears to be thinner.
This particular question is about horizontal stretching, however. Stretching the graph horizontally by a factor of 4 results in the new function g(x) = (x/4)^2. Try graphing x^2 and also (x/4)^2 on the same set of axes to observe this phenomenon.

Find y
To find y, we make use of the relationship between sides lengths 44 & y and angle 39
The relationship is:

i.e.

Make y the subject
