Answer:
See below.
Step-by-step explanation:

Convert the cotangent to cosine over sine:

Use the cofunction identities. The cofunction identities are:

To convert this, factor out a negative one from the cosine and sine.

Recall that since cosine is an even function, we can remove the negative. Since sine is an odd function, we can move the negative outside:

Answer:
c4+8c3+−3c2+−7c
Step-by-step explanation:
Let's simplify step-by-step.
−3c4−5c2−7c+4c4+8c3+2c2
=−3c4+−5c2+−7c+4c4+8c3+2c2
Combine Like Terms:
=−3c4+−5c2+−7c+4c4+8c3+2c2
=(−3c4+4c4)+(8c3)+(−5c2+2c2)+(−7c)
=c4+8c3+−3c2+−7c
You would have to watch 62 3D movies to make an annual pass the less expensive option out of the two of them.
62x25 = 1550
Answer:
70 miles /hour = r
Step-by-step explanation:
d=rt
Substitute d=350 miles and t = 5 hours
350 miles = r* 5 hours
Divide each side by 5 hours
350 miles = 5 hours = r
70 miles /hour = r
Answer:
10 rocks
Step-by-step explanation:
The cost on startup is $10 and each painted rock cost around $0.75 to make. A store pays startup cost and buy painted rocks for $0.75 each there no profit because the cost price and selling price is the same.
