The diameter / by 2 is the radius and you can find the area by using the equation pi times the radius squared. I was thought to remember the phrase "Pies are square" if that helps at all.

Given f(x)=3x-1 find f(-1)
vaieri [72.5K]

Answer:

<h2>f( - 1) = - 4</h2>

Step-by-step explanation:

f(x) = 3x - 1

To find f(-1) substitute the value of x that's

- 1 into f(x). That's for every x in f(x) replace it with - 1 and solve

That's

f( - 1) = 3(-1) - 1

= - 3 - 1

We have the final answer as

<h3>f(-1) = - 4</h3>

Hope this helps you

On a coordinate plane the coordianits of vertices the and t for a polygon are r(-7,3) and r (3,3) what is the length of side rt
NemiM [27]

The length is 10.


Since the two points share the same y-coordinate, the segment rt is horizontal.


This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.


So, we have


\overline{RT} = |-7-3| = |-10| = 10
