Answer:
.
Step-by-step explanation:
Since we are in quadrant two, cosine value is negative while sine value is positive.
We are going to use the Pythagorean Identity: 
.
Since cosine and secant are reciprocals then they will have the same sign as along as they both exist.
.
I don't see this answer as I'm going to rationalize the denominator.

Answer:
39.25 cubic feet of paint will be needed by Ellis.
Step-by-step explanation:
Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder of radius r and height h is given by:
V = \pi r^2h = 3.14r^2h
How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?
This is the combined volume of these 10 fenceposts.
They are each 5 feet tall and have a diameter of 1 foot.
Radius is half the diameter, so r = \frac{1}{2} = 0.5. Also h = 5
10 fenceposts:
Each has the same volume, so:
V = 10(3.14)r^2h = 31.4(0.5)^2(5) = 39.25
39.25 cubic feet of paint will be needed by Ellis.

You order them least to greatest, then take out your mean, median, and mode. Then you've got your outliners left over.
5 % 8,000 decreases to 400 by 5 %
Then the second term’s denominator is
