Answer:
B
Step-by-step explanation:
Given
x² + 3x + 2 = 0
To factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are 2 and 1, since
2 × 1 = 2 and 2 + 1 = 3, thus
(x + 2)(x + 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1
Question:
<em>Today, a boat is valued at $45,000. The value is expected to decrease at a rate of 8.5% each year. What is the value of the boat expected to be 3 years from now?</em>
Answer:
<em>C.) 34,472.74</em>
Hope this helps!
Tammy has charged $17 + $36 + $11 = $64 in total.
So Tammy has to pay $64 before she have interest charged to her.
If the APR is 21% then monthly interest is 21% / 12 = 1.75%
So if she don't pay those $64 by the end of month, she will have to pay $64 + $64 * 0.0175 = $64 + $1.12 = $65.12.
Given that a person's normal body temperature is 98.6 ° F, and according to physicians, a person's body temperature should not be more than 0.5 ° F from the normal temperature, to determine how you could use an absolute value inequality to represent the temperatures that fall outside of normal range, the following logical-mathematical reasoning must be carried out:
As long as the normal temperature is 98.6 ° F, and its variation should not be greater than 0.5 ° F in its increase or decrease, it is correct to say that the range of normal body temperatures is equal to 98.6 - 0.5 to 98.6 + 0.5, that is, it has a variability that goes from 98.1 ° F to 99.1 ° F.
Thus, the absolute value inequality of 0.5 (both subtracting and adding) determines the limits of the temperature parameter considered normal.
