Answer:

8.5 pi

Step-by-step explanation:

C= 2 pi r

21 pi= 2pi r

r= 10.5

Arc length= 2pi r(145/360)

21 pi( 145/360)= 8.5 pi

4% = 0.04

 multiply percent by sales to get total commission:

2,880 * 0.04 = 115.20

 add that to her base pay:

275 + 115.20 = $390.20 total earned

Determine which function(s) is not a linear function. Select all that apply.
Drupady [299]

Answer:

x = 3.

Step-by-step explanation:

x = 3 is not linear. By definition a linear function has 2 variables, a dependent and independent variable. This has only x and a constant. It is a linear equation but not a linear function.

4. What is the equation of line passing through (-2,4) and parallel to the line y<br> + 3x = 4?
aliya0001 [1]

Answer:

y=-3x-2

Step-by-step explanation:

step 1- find the slope

parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3

step 2- use the point slope form which is y-y1=m(x-x1)

and substitute in the numbers (only substitute y1,x1, and m)

m is the slope which we found to equal -3

x1 and y1 are the points that they gave us (-2,4) are (x1,y1)

x1=-2

y1=4

step 3- substitute

y-y1=m(x-x1)

y-4=-3(x-(-2))

simplifies to y-4=-3x-6

add 4 to both sides to get y=-3x-2
