Answer:
23 sin 55°
x = ------------------ (matches first answer choice)
sin 85°
Step-by-step explanation:
Note that 2 angles and 1 side length are given. This is a typical application of the Law of Sines. The formula for finding the length of side x is:
23 sin 55°
x = ------------------ (matches first answer choice)
sin 85°
Answer:

or

Step-by-step explanation:
-7,-3,1,5,... is a arithmetic sequence.
Arithmetic sequences have a common difference. That is, it is going up by 4 each time.
When you see arithmetic sequence, you should think linear equation.
The point-slope form of a line is
.
m is the common difference, the slope.
Any they are using the point at x=1 in the point slope form. So they are using (1,-7).
So let's put this into our point-slope form:


Subtract 7 on both sides:

So your answer is

Answer:
Go for the 200 copies!
Step-by-step explanation:
Paying 77 times $0.39 is $30.03, which is more than the 200 copies offer, so even if you throw away all the copies you don't need, the 200 offer is still cheaper!
The domain- Is the function provides an "output" or value for each member of the domain
Range- The difference between the lowest and highest values.
I think your answer is 125 cm. Good Luck.
