Answer:
8
Step-by-step explanation:
<u>Area of a circle = πr^2</u>
64π / π = πr^2 / π
sqrt(64) = sqrt(r^2)
8 = r
Answer: 8
The answer to the question
Answer:
The value of the expression is 80.
Step-by-step explanation:
14 - 6 = 8.
10 x 8 = 80.
Answer:
<h3>5x</h3>
Step-by-step explanation:
The additive inverse of a function is that value added that will sum it up to zero
If y is the additive inverse of 4x, then y = -4x
Given the expression 17x+3y
Substitute y = -4x into the expression to have;
17x + 3(-4x)
17x -12x
5x
Hence the value of the expression in terms of x is 5x
The tangent meets the radius at a right angle.
We use (the converse of) the Pythagorean Theorem to check:

Not a right triangle
