Answer:
Part A: x⁴ + x³ + x²
Part B: (4·x + 2) + (-5·x + 6) = -x + 8
Step-by-step explanation:
Part A:
We note that standard form means that the terms of the polynomial are arranged in order starting from the the largest exponential of the polynomial to the smallest exponent
Therefore, we have
x⁴ + x³ + x² is a fourth-degree polynomial with three terms in standard form
It is known that the above polynomial is in standard form based on its ordered arrangement from the largest exponential to the smallest exponential
Part B:
Polynomial are closed under addition, that is when two polynomials are added only the coefficients change as the exponents and variables remain unchanged as follows;
(4·x + 2) + (-5·x + 6)
= 4·x + 2 - 5·x + 6
= 4·x - 5·x + 2 + 6
= -x + 8 which is a polynomial with the same variable and exponent.
Answer:
1. 25
Step-by-step explanation:
divide 20 by 16
20/16 = 1.25
Answer:
or 0.707
Step-by-step explanation:
cos(315) is equivalent to cos (
)
You can look at the unit circle to find the cos value for this. Keep in mind that cos is the x value of the corresponding coordinate.
12 different outcomes are possible. In the first round you have 4 choises and in the second one you have 3
Answer:
$68
Step-by-step explanation:
First, find out what 15% of $80 is. 15% as a decimal is 0.15. Multiply 0.15 and 80 together.
0.15 x 80 = 12.
Now, subtract 12 from the original price, 80.
80 - 12 = 68.
