Shonda made a model of a solid ice cream cone with a spherical scoop of ice cream on top, made out of clay.
which formulas are needed to calculate how much clay she used?
choose all answers that are correct. (in these formulas, r represents radius, h represents height, l represents length, and w represents width.)
a: v = 1/3 x 3.14 x r^2 x h
b: v = 3.14 x r^2 x h
c: v = i x w x h
d: v = 4/3 x 3.14 x r^3

(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

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
