The percentage of adult height attained by a girl who is x years old can be modeled by
f(x)=62+35log(x−4)
where x represents the girls age (from 5 to 15) and f(x) represents the percentage of her adult height. Use the function to solve. Round answers to the nearest tenth of a percent. Approximately what percentage of her adult height has a girl attained at age 13?

The girl attained at age 13 has attained 95.4% of adult height.

Step-by-step explanation:

We are given the following in the question:

Here, x is the girls age from 5 to 15 and f(x) represents the percentage of her adult height.

We have to approximate percentage of her adult height has a girl attained at age 13.

We put x = 13 in the above equation:

Thus, a girl attained at age 13 has attained 95.4% of adult height.

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
