3. Determine whether the data show a linear relationship by plotting the points and drawing the line. If so, write an equation of a line of fit. Estimate y when x = 15 and explain its meaning in context.
Months,
2 6 12 16 20
Hair length,
7.2 13.1 22.3 29.5 36
no
b. yes: y = 4x+1.6: y =61.6: After 15 months, the hair length will be 61.6 inches.
c. yes: y=-1.6x +4: y = 28: After 15 months, the hair length will be 28 inches.
d. yes: y = 1.67 +4; y = 28: After 15 months, the hair length will be 28 inches

Step-by-step explanation:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
