Answer:
1.11
Step-by-step explanation:
If you know all the side lengths of a right triangle, you can use trigonometry ratios to find sines, cosines, and tangents.
sin(x) = opposite / hypotenuse
cos(x) = adjacent / hypotenuse
tan(x) = opposite / adjacent
If we are finding the tangent of angle X, we can see that the opposite side is 72 units and the adjacent side is 65 units.
Using the ratio, we can conclude that tan(x) = 72/65.
Use your calculator to divide, and you will get 1.10769, which is approximately 1.11.

The answer is 3/2 because you do the slope equation and that answer
Answer:
Step-by-step explanation:
This may seem a bit tricky because we are not given enough info really to plug in and solve for the rate. We are told, however, that we are interested in doubling whatever amount we invested. So it is up to us to pick an amount for P, then double it for A(t). Let's use P = 1000 so A(t) = 2000. Filling in then:
and
We need to get that r all by itself and right now it's quite buried. Begin by dividing both sides by 1000 to get
Now take the 60th root of both sides to get
Subtract 1 from both sides to get
and multiply both sides by 12 to finally get the rate in decimal form:
r = .13943328
To get that in a percent form, multiply it by 100:
r = 13.9%
