Factor Completely : 6w2 – 66w – 72
Answer:
6w*6w-66*w-72
Hope This Helps!!!
Answer:
6(w - 12)(w + 1)
Step-by-step explanation:
6w² - 66w - 72 ← factor out 6 from each term
= 6(w² - 11w - 12) ← factor the quadratic
Consider the factors of the constant term (- 72) which sum to give the coefficient of the w- term (- 11)
The factors are - 12 and + 1 , since
- 12 × 1 = - 12 and - 12 + 1 = - 11 , then
w² - 11w - 12 = (w - 12)(w + 1) , so
6w² - 66w - 72 = 6(w - 12)(w + 1) ← in factored form

What is 6[cos(70°) i sin(70°)] ÷ 2[cos(5°) i sin(5°)]? 3[cos(75°) i sin(75°)] 4[cos(75°) i sin(75°)] 3[cos(65°) i sin(65°)] 4[cos(65°) i sin(65°)].
Step-by-step explanation:
If we have
[tex] \frac{r( \cos(x) + i \sin(x) }{s( \cos(v) + i \: sin(w)} = \frac{r}{s} ( \cos(x - v) + i \: sin(x - w)[/tex]
So first we know the modulus is 6 and 2 for the second one so we get
[tex] \frac{6}{2} = 3[/tex]
First degree is 70 , and second is 5 so our degree will be 65 in the second because
70-5=65
Our answer is
[tex]3( \cos(65) + i \: \sin(65) )[/tex]

In a study of the effect of playing video games on sleep quality, researchers randomly assigned some participants to play an up-tempo video game for either one or three hours before bed. Other participants had no engagement with electronics in the time before bed. Then, the researchers assessed all the participants' sleep quality (e.g., number of awakenings, percentage of time in deep sleep) during an overnight sleep study. In this experiment, the time spent playing video games (e.g., one or three hours) is the ________.
In this experiment, there is an independent variable that is the time spent playing video games.
What is an independent variable?In research there are different ways to test a hypothesis. One of them is the experiments in which we have one or more factors that can be modified to alter the result.
These factors are known as independent variables because their variation does not depend on other factors. On the contrary, they influence the variation of other factors that are known as dependent variables.
According to the above, it can be inferred that time is the independent variable of this research because its modification is planned to evaluate the different variables that it can cause.

car buyer bought a used car for $20,250. The car depreciates by 11% per year. The following equation describes the value of the car, where y represents the number of years since the car was purchased. v ( y ) = 20 , 250 ( 1 − 0.11 ) y Which equation is equivalent and can be used to determine the value of the car 6 months after it was purchased? v ( y ) = 20 , 250 ( 0.89 ) 6 v ( y ) = 20 , 250 ( 0.89 ) 6 v ( y ) = 20 , 250 ( 0.89 1 12 ) 6 v ( y ) = 20 , 250 ( 0.89 1 12 ) 6 v ( y ) = 20 , 250 ( 0.89 ) 1 12 ( 0.89 ) 6 v ( y ) = 20 , 250 ( 0.89 ) 1 12 ( 0.89 ) 6 v ( y ) = 20 , 250 ( 0.89 ) 6 ( 0.89 ) 6

What is deprecation?
Depreciation is the rate of decrease in value of an asset. When an asset depreciates, it declines in value with the passage of time.
What equation represents the value of the car after 6 months?The formula that can be used to represent depreciation is:
FV = P (1 + r)^n
FV = Future value P = Present value R = interest rate N = number of yearsv(y) = 20,250(1 - 0.11)^t
v(y) = 20,250(0.89)^6/12

1. Is (0,9) a solution?
y = -3x + 5
Answer:
no
Step-by-step explanation:
to determine if (0, 9 ) is a solution substitute x = 0 into the equation and if the result is 9 then it is a solution
y = - 3(0) + 5 = 0 + 5 = 5 ≠ 9
then (0, 9 ) is not a solution to the equation
In 1950, Town A had a population of 200 people and the population increased by 200 people each year. In 1950, Town B had a population of 200 people and the population increased by 10% each year. Which town will eventually have the greater population? Which town had the greatest population in 1990?
Town B will have more population in 1990.
Given that, in 1950 town A had a population of 200 people and the population increased by 200 people each year. In 1950, Town B had a population of 200 people and the population increased by 10% each year.
We need to find which town will have more people in 1990.
Town A = 1990 - 1950
= 40 years
Therefore, in 40 years it will have = 40 × 200 = 8000 population.
Town B = It is increasing by 10% each year,
so in 40 years,
P = 200(1+0.1)⁴⁰
P = 9051
Since the population of town B is greater than the population of town A.
Hence town B will have more population in 1990.

What is the slope of the line that passes through the points (8, -6) and (5,−1)? Write your answer in simplest form.
Answer:
-5/3
Step-by-step explanation:
To find the slope of the two points, use the formula: Y2-Y1/X2-X1
-1 is Y2, -6 is Y1, so that will be our numerator in this equation
5 is X2, 8 is X1, so that will be our denominator in this equation
So our equation becomes, -1+6/5-8 (Two negative signs create a positive so instead of -6 it becomes +6)
When we solve this, we get 5/-3
So our slope is -5/3
Hope this helps!

So I was wondering how to do this, 15-[tex]\sqrt{x+2}[/tex] what value of x does the expression make sense
Answer:
Step-by-step explanation:
The question makes sense for all values of x, but I imagine that is not exactly what you mean.
I think you mean for what values of x does the question produce a real square root?
The answer is as long as x + 2 does not drop below 0, the results will be real.
Put mathematically x ≥ -2 gives a real result. For now just don't try and take the square root of a minus number.
Answer:
x >= -2
Step-by-step explanation:
For real numbers (like, for graphing or applications) the number inside the square root symbol must be a positive number. So, if x is -3, -4, -5 you will get a negative number inside the square root. If x is -2, you get a zero, which is fine(allowed, no problem) If x is -1, you get a 1 inside there, which is no problem. Any positive number for x yields a positive number inside the square root.
So x must be greater than -2.
Saying what x is or can be is what is "the domain"
Domain: {x | x >= -2}
This is set notation.
Interval notation looks like this:
[-2, infinitysymbol)
Simply, x >= -2

If it takes 68 seconds for you to walk up a flight of stairs from the first floor to the third-floor how long would it take you to walk from the first floor to the seventh floor
Answer:
204 Seconds
Step-by-step explanation:
Step 1 - 68/2 this is to find the unit cost in seconds that it takes to walk up the stairs to get 34.
The 2 is from the amount of flights of stairs you have to walk up to get from floor 1 to floor 3.
Step 2 - 34*6 this is because the unit price is 34seconds/flight of stairs to get 204.
Answer 204 Seconds.

what is the value of s
Answer:
17
Step-by-step explanation:
First of all, based on the Pythagorean theorem, a^2 + b^2 = c^2
(it's very important that the ∠ABD angle is 90 degrees)
8^2 + 15^2 = s and 5^2 + 15^2 = CD (but the original question doesn't want the value of CD, so we just need to solve for s)
64 + 225 = 289 now remember, 289 is s^2, and we only want the value of s, so we have to find its square root: √289 = 17
