Answer:
x=9.768
y=6.972
Step-by-step explanation:
For this problem we have to use the trig relationships of cos and sin to figure out the lengths. Cos is equal to adjacent/hypotenuse so we can set it as x/r=.814 and since r is equal to 12 we can do 12 times .814 to get x.
We do a similar process for sin but sin is equal to opposite/hypotenuse so we can set up the equation y/r=.581 and we simply multiply both sides by 12 to get 12*.581 to get y.
Also for future reference adjacent and hypotenuse are based on the angle at use, since ∅ is on the bottom left x is the adjacent side and y is the opposite side.
Time is most frequently the independent variable. It should go on the x axis. This question is no exception.
The account balance is the dependent variable and should go on the y axis.
You can only pick one of these and a couple are absurd. Time goes on the x axis and the account balance goes on the y. We care nothing about what the interest rate creating the increase.
The answer is C
Answer:
Step-by-step explanation:
Cos(Q) = adjacent to Q/Hypotenuse
adjacent = 15
Hypotenuse = 17.7
Cos(Q) = 15/17.7
Cos(Q) = 0.8475
The answer is C.
D is impossible. The cos of any angle can never be more than 1.
B is Tan(Q). They are not the same.
A is Sin(Q)
