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.
If you put in the substitutions it would be 2*2-(2*2*4)+(3*2)-(-4*2)+(2*4).
Simplified further by multiplying it would be 2*2-8+6--8+8
the negative 8 could be simplified further since the negatives cancel out so you'll have 2*2-8+6+8+8.
Then using the order of operations you would multiply the 2's together first to get 4 so you have 4-8+6+8+8.
After that it's simple addition giving you an answer of -26.
I'm not sure if you're looking for the final answer or just the equation with substitutions but there's both.
Answer:
hi
Step-by-step explanation:
4- 3*1=3
6*1/100= 0.06
3+0.06= 3.06
5- 7*1= 7
3*1/10= 0.3
4*1/1,000= 0.004
7+0.3+0.004= 7.304
7- 3.3, 3.30
8- 9.3000, 9.30
9- 9.6, 9.600
10- 4.4000, 4.40
for #4-5 just put the number of 0s in the denominator of the fraction for the answer
3 quarters, and two thirds of a quarter so It's [3 2/3]
Answer:
585 cars
Step-by-step explanation:
Given

per floor
Required
Determine the total number of cars
This is calculated by multiplying number of cars per floor by number of floors.



<em>Hence, there are 585 cars in total</em>
