- c) 72 million
Step-by-step explanation:
It is convenient to let a spreadsheet or graphing calculator do the repetitive evaluation of a function like this. That simplifies the work and reduces errors.
The function is shown in the attachment written in Horner form, which is convenient for evaluation by hand or using a calculator.
<span>Setting expressions equal to one another gives us an equation.
In an equation, our goal is to isolate the variable; we must "undo" everything that has been done to the variable. We work backward; the last thing done to the variable will be the first thing we undo.
We "undo" things by performing the opposite operation; for instance, if the last thing done to our variable was that 3 was subtracted from it, we would undo that first by adding 3 to both sides.
What we do to one side we must do to the other in order to preserve equality.
We would continue this process of working backward until the variable was isolated; this would give us our solution.</span>
Y=mx+b
y=-1/2x-0.9
Yeah the y intercept is kinda hard
Knowing that your area is:
you can find the radius as:
;
With this you can evaluate the circumference as:
