Answer:
See below.
Step-by-step explanation:
Cos O is positive in the first and 4th quadrants and sin O is negative in the 3rd and 4th quadrants.
So the answer is Quadrant 4.
cos^2 O = 1 - sin^2 O
= 1 - (-3/5)^2
= 16/25
So cos O is +√(16/25)
= 4/5.

The future value
This is calculated as:

This gives:





<em>The future value to the nearest cent is: $81.03</em>
If you add 5x to 2x+2 you will get 7x+2. You would set this equation equal to 80, so it would be 7x+2=80. When you solve this you will get 11.1428571429, which can be rounded to 11, 11.1, or 11.14, whichever you prefer.
Answer:
Step-by-step explanation: It’s the perimeter of each shape so you add the outside of the shape up. The second question is 11.2 and 12 as the width and length. The 11.2 is the width so on the other side it is 11.2, and the length is 12 so the other side is 12. You then add them all up and get your answer.
The answer is A because when you plug in the points into the distance formula, you will get square root of 17 squared plus 17 squared. Hope this helps!
