Answer:
$6,106.87
Step-by-step explanation:
The total of percentage deductions is ...
state tax + city tax + social security + medicare
= 3.5% +2.5% +6.2% +1.45% = 13.65%
Then Ryleigh's take-home pay is ...
gross(1 -13.65%) -112 = 5161.28
gross = (5161.28 +112)/0.8635 = 6106.87
Ryleigh's monthly gross is $6,106.87.
Answer: t=-3h+25
Step-by-step explanation:
t=-3h+25
25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.
The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.
Answer:
x³ - 5x² + 81x - 405 = 0
Step-by-step explanation:
Complex roots occur in conjugate pairs.
Thus given x = - 9i is a root then x = 9i is also a root
The factors are then (x - 5), (x - 9i) and (x + 9i)
The polynomial is the the product of the roots, that is
f(x) = (x - 5)(x - 9i)(x + 9i) ← expand the complex factors
= (x - 5)(x² - 81i²) → note i² = - 1
= (x - 5)(x² + 81) ← distribute
= x³ + 81x - 5x² - 405, thus
x³ - 5x² + 81x - 405 = 0 ← is the polynomial equation
