Answer:
a) 100π
Step-by-step explanation:
A = πr²
A = (10²)π
A = 100π
Answer:
{-11,8,13}
Step-by-step explanation:
The domain is the input values (or x)
The range is the output values (or y)
The range is (-11,8,13)
You use long division when you divide polynomial by other polynomials. You use synthetic division to divide polynomials by binomials of the form (x-k).
Answer:
y=1/2x+2
Step-by-step explanation:
The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.
To find the gradient is a little more tricky, but we can follow the formula:
, where rise is the vertical value and run is the horizontal value
So we sub in our values:

And simplify:

So now we sub in our new found values into y=mx+c:
y=1/2x+2
