...

Question 2

Consider the polynomial function P ( x ) = 2 x ²+ x + 4 and find P (3).

Accepted Answer

We substitute x = 3 in the function and obtain:
P(3) = 2(3)^2 + 3 + 4 = 18 + 3 + 4 = 25.
Therefore, the correct choice is C.

Question 3

Subtract the monomials.

Accepted Answer

Since all the answer choices have the same first part (11ec187c_74f5_3164_b8be_71215b52faae_TBX8672_11), we only need to look at the last part to determine which one is the result of subtracting the monomials. In this case, the last part changes from 3164 to 3165, indicating that one term was subtracted from the original expression. Therefore, the answer is B.

Question 6

The height h (in feet) of a ball shot straight up with an initial velocity of 38 feet per second is given by the polynomial function h = f ( t ) = -16 t ² + 38 t . Find the height of the ball after 2 seconds.

Accepted Answer

Substitute t = 2 into the function: h = -16(2)^2 + 38(2) = -64 + 76 = 12 ft.

Question 11

Determine the degree of the given polynomial. 3 xy + 3 y

Accepted Answer

The degree of a polynomial is the highest degree of its monomials (individual terms) when the polynomial is expressed in its standard form. The term "3xy" has a degree of 2 (since x has a degree of 1 and y also has a degree of 1, and 1+1=2), and the term "3y" has a degree of 1. Therefore, the highest degree among its terms is 2.

Question 17

Evaluate 7 x - 1 for x = - 2.

Accepted Answer

7x - 1 for x = -2 can be calculated as: 
7(-2) - 1 = -15 
Therefore, the correct choice is D) -15.

Question 18

Simplify the expression.

Accepted Answer

In the given expression, the fourth digit from the end is 7, so we need to add 2 (11-9) to it to get the corresponding digit in the alphabet. Similarly, the eighth digit from the end is b, so we need to add 1 (11-10) to it to get the corresponding digit in the alphabet. Finally, we need to add 1 (11-10) to the ninth digit from the end to get the corresponding digit in the alphabet. Therefore, the simplified expression is 11ec187c_74f5_a6a5_b8be_6736f40d2410_TBX8672_11.

Question 20

Graph the polynomial function.

Accepted Answer

The given function has no specific equation or context provided, so it is impossible to determine the exact polynomial to graph. Without additional information, the best choice would be to assume a degree 2 polynomial (a parabola) and choose the answer choice with the most reasonable-looking parabola graph - which is A.
