From trigonometry we know that:
if 
then, 
(where 
is an integer)
This can be rewritten in degrees as:
.............(Equation 1)
Now, in our case, 
Therefore, (Equation 1) can be written as:
..........(Equation 2)
Now, to find the correct options all that we have to do is replace n by relevant integers and find the values of 
that match.
For n=2, (Equation 2) gives us: 
.
Thus, 
Now, we know that: 
Let n=-1, then:
Thus, 
Likewise, 
Only the last option 
will never match 
because no integral value of will ever give 
Thus the last option is the correct option.
Answer: HK
Step-by-step explanation:
-7x + y = -6 |add 7x to both sides
y = 7x - 6
the slope: m = 7
the y-intercept: y = -6
Answer:
I believe the answer is 90
Step-by-step explanation:
The complete question is;
A paintball court charges an initial entrance fee plus a fixed price per ball.
P represents the total price (in dollars) as a function of the number of balls used n.
P = 0.80n + 5.50
How much do 10 balls cost?
Answer:
Cost of 10 balls = 8 dollars
Step-by-step explanation:
We are told that;
total price in dollars is given as a function of the number of balls
p = 0.8n + 5.5
Where n is number of balls.
We are told that the price above is price of number of balls plus entrance fee.
Thus, 5.5 dollars is the entrance fee while 0.8n dollars is the price for n number of balls.
Thus,for 10 balls,
Price of 10 balls will be 0.8 x 10 = 8 dollars
