Answer:

x = 15

Step-by-step explanation:

<u><em>Using Pythagorean Theorem</em></u>

=> c^2 = a^2+b^2

<u><em>Where c= x, a = 12, b = 9</em></u>

=> x^2 = (12)^2+(9)^2

=> x^2 = 144+81

=> x^2 = 225

Taking sqrt on both sides

=> x = 15

Given the function g(x) = x2 + 10x + 20, determine the average rate of change of
Dmitrij [34]

A function assigns the values. The average rate of change for the given function g(x) is 1.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The average rate of change of a function is given by the formula,

Average rate of change, = [f(b)-f(a)]/(b-a), [a,b]

Where a is the lower limit and b is the upper limit.

Given the upper limit for the function is 0, therefore, the value of a is 0, similarly, the value of b is -9. Thus,

a = 0

g(a) = 0²+10(0)+20 = 20

b = -9

g(b) = (-9)²+10(-9)+20 = 11

The average rate of change for the function g(x), can be written as,

\text{Average rate of change}= \dfrac{g(-9)-g(0)}{-9-0}=\dfrac{11-20}{-9} = 1

Hence, the average rate of change for the given function g(x) is 1.

The circumference of a circle is 25.12 yards. What is the radius of the circle?
ANEK [815]
The circumference is pi times diameter, so put 25.12 over pi to get the diameter. That would be 8. Then divide by 2 to get the radius. That would be 4
