Answer:
20u
Step-by-step explanation:
The Pythagorean Theorem is a good resource for this question. The pythagorean theorem is only used for right triangles. This formula is comprised of a^2+b^2=c^2, a and b are the two legs of the triangle and c is the hypotenuse which will always be the longest leg on the triangle. In this case we could type into our calculator 12^2+16^2=400 we then take the square root of 400 which is 20.
Answer:
Step-by-step explanation:
Point slope form is: 
We are given the slope of 
and the point of (8,4).
Replace 'm' with -5/6, 'x1' with 8, and 'y1' with 4.
I do not see any options that match this, but the boxed equation should the correct answer.
F(x) = -(x + 1)^2 + 4
Vertex = (-1, 4)
Domain is all real numbers.
Range is f(x) <= 4
