Answer:
theta = 135+ n360
theta = 225+n360
Step-by-step explanation:
-sqrt(2) = 2 cos theta
Divide each side by 2
-sqrt(2)/2 =2/2 cos theta
-sqrt(2)/2 = cos theta
Take the inverse cos on each side
arccos (-sqrt(2)/2) = arc cos(cos theta)
135 = theta
Now remember this only gives you the value between 0 and 180 degrees.
Take 360 minus the value found to get the other angle since this is cosine
360 -135 = 225
Now remember this is cyclical, so we can add 360 to each of these values and we will get the same amount
theta = 135+ n360
theta = 225+n360
The common factor of 5x2 is y5x
k = - 2 is excluded from the domain
the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that k cannot be
solve k + 2 = 0 ⇒ k = - 2 ← excluded value
Answer:
$159,750
Step-by-step explanation:
191700=5x+x x=lot
191700/6=31950
x=31950
house=5x
5(31950)
house= 159750
Answer: A. 20%
Step-by-step explanation:
First, to find the total number of teachers, we can add 25+32+18+5+20=100
Next, we divide the number of teachers in 2014 (20) by the total number of teachers (100) as follows:
20 ÷ 100 = 0.2
Finally, to make 0.2 a percentage, we can multiply 0.2 X 100 = 20
Therefore, the correct answer is A.
