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.

Answers

Answer:

One possible polynomial is given by: [tex]f(x) = -x(x-3)^2[/tex]

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

Single root at 0, double root at 3:

This means that:

[tex]f(x) = a(x - 0)(x - 3)(x - 3) = ax(x-3)^2[/tex]

Decreases as x approaches infinity.

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

[tex]f(x) = -x(x-3)^2[/tex]

Formulate a step-by-step explanation (in words) on how to simplify (x^2+2x-8)/(x^2+7x+12). Be sure to write a sentence for each step (use correct mathematical language). Which step did you find most difficult to explain and why?

kindly go through the work i have done. ask for any clarification

Answer:

(x - 2) / (x + 3)

Step-by-step explanation:

We proceed to factor both polynomials:

x^2+2x-8 = (x + 4) * (x - 2) in numerator

x^2+7x+12 = (x + 4) * (x + 3)  in denominator

therefore, there is a common factor (x + 4) which can be cancelled in the original rational expression, resulting in the following rational expression:

(x^2+2x-8)/(x^2+7x+12) = (x - 2) / (x + 3)

All steps where pretty simple.

What is 4000 divided by 70

Answers

Answer:

57.1428571429

Step-by-step explanation:

The proper calculation of 4000 divided by 70 is approximately 57.14285714285714.

To calculate 4000 divided by 70 properly, we can perform the division:

4000 ÷ 70 = 57.14285714285714

The quotient of 4000 divided by 70 is approximately 57.14285714285714.

When dividing, 70 can be divided into 4000 approximately 57 times, with a remainder. To obtain a more precise decimal representation, the division can be carried out to more decimal places. However, for the purpose of this calculation, we have rounded the result to 14 decimal places.

Therefore, the proper calculation of 4000 divided by 70 is approximately 57.14285714285714.
