If Yarmouth is 6.5C and Sydney is 8C colder you would just subtract.
6.5-8=-1.5C
1/2(-14x + 14) + 14x
<em><u>Distributive property.</u></em>
-7x + 7 + 14x
<em><u>Combine like terms.</u></em>
7x + 7 (This is the simplified answer.)
When multiplying binomials, one takes the first binomial and multiply each term by the first term of the second binomial, and then you do the same with the second term of the second binomial, to obtain:
4a^2+14a-2a-14
4a^2+12a-14
Well formula is pie times radius squared times height over 3
Plug it all in and your answer is 20.94
Answer:

Step-by-step explanation:
The cotangent of theta is:

For pi/2 < theta< pi
This means that the angle is in the second quadrant. In the second quadrant, the cosine is negative and the sine is positive. This means that the cotangent will be negative.
Secant:

In this question

So

Using cross multiplication



Now we apply the following trigonometric identity:






Since the angle is in the second quadrant, the sine is positive.

Finally, the cotangent:
