Answer:
Step-by-step explanation:
Circumference is the perimeter of a circle. It can be found using the formula:
However, we are given the radius.
- The radius measures from the center to the edge of the circle.
- The diameter measures from edge to edge through the center.
- So, the diameter is twice the radius, or d=2r
The formula can be rewritten as:
We know the circumference is 25.12 inches.
Let's round pi to 3.14
We want to solve for the radius, so we must isolate it.
Divide both sides by 3.14 because the inverse of multiplication is division.
Divide both sides by 2.
The radius of the disc is <u>4 inches.</u>
17 . Find the values of g(9) and h(-14) and add them together.
The function equations are given to find their values substitute 9 in g(x) and -14 in h(x)
20. They said f(x) = 2x + 9 and f(x) = 15 , which means they are equal to each other.
So write them as 2x + 9 = 15 , and solve the equation to find the value of x.
25. Here all you have to do is substitute 4 into the f(x) equation to find f(4)and you will have your answer.
Hope this helped!
