Question 1

Which of the following numbers is NOT an integer?

Accepted Answer

$$0.612$$

Question 2

Evaluate $$(-2)^4$$ and $$-2^4. $$Are the results the same? Why or why not?

Accepted Answer

No, $$(-2)^4 = 16$ and -2^4$ = -16$$ because $$-2^4$$ means the negative is not included in the exponent.

Accepted Answer

$$-8y^3$$ + $$24y^2 - 30y - 4$

Question 4

Which of the following is a correct way to convert $$-81^{1/4} to $$radical form and simplify?

Accepted Answer

$$-\sqrt[4]{81} = -3$$

Question 5

Given the polynomial $$-4x^5y^2$ + 8y^3$ + 2y - 7$, what is the degree of the polynomial?

Accepted Answer

Degree $$7$$ because the term $$-4x^5y^2$ has degree 5+2=7$.

Question 13

If you multiply $$(2y - 4) by$$ $$(-4y^2 + 8y + 1$$)$$, what is the coefficient of y^2$ in the expanded expression?

Accepted Answer

$$24$$

Question 14

Which of the following is a common mistake when evaluating $$-2^4$$?

Accepted Answer

Calculating $$(-2)^4$$ instead of $$-2^4$$

Question 15

Which of the following is the correct degree of the constant term $$-7 in $$the polynomial $$-4x^5y^2$ + 8y^3$ + 2y - 7$?

Accepted Answer

Degree $$0$$

Question 16

A medical researcher uses the polynomial $$-4x^5y^2$ + 8y^3$ + 2y - 7 to $$model the spread of a virus, where $$x is $$time and $$y$ is population. Which term represents the interaction between time and population?
