10. Write a polynomial in factored form with a single root at 0 and a double root at 3 that decreases as x approaches infinity.

One possible polynomial is given by:

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

Single root at 0, double root at 3:

This means that:

Decreases as x approaches infinity.

This means that the leading coefficient should be negative. I am going to use -1. So

The total nom of  code that can be used is equal to 5+3 = 8

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The answer is in the image 

The solution is given in the image below

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

30% of 420 are first year students

first year students = (30/100 )*420

=126 students

Student who are not in first year = 420-126

=294 students
