Answer:
Step-by-step explanation:
Given:
![\sin^2\theta=0.75](https://tex.z-dn.net/?f=%5Csin%5E2%5Ctheta%3D0.75)
To find ![\cos\theta](https://tex.z-dn.net/?f=%5Ccos%5Ctheta)
Using trigonometric relations for sums and differences of squares of the ratios.
We know:
![\sin^2\theta+\cos^2\theta =1](https://tex.z-dn.net/?f=%5Csin%5E2%5Ctheta%2B%5Ccos%5E2%5Ctheta%20%3D1)
Plugging in
in the above relation.
![0.75+\cos^2\theta =1](https://tex.z-dn.net/?f=0.75%2B%5Ccos%5E2%5Ctheta%20%3D1)
Subtracting both sides by 0.75.
![0.75+\cos^2\theta-0.75 =1-0.75](https://tex.z-dn.net/?f=0.75%2B%5Ccos%5E2%5Ctheta-0.75%20%3D1-0.75)
![\cos^2\theta =0.25](https://tex.z-dn.net/?f=%5Ccos%5E2%5Ctheta%20%3D0.25)
Taking square root both sides.
![\sqrt{\cos^2\theta} =\sqrt{0.25}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Ccos%5E2%5Ctheta%7D%20%3D%5Csqrt%7B0.25%7D)
∴
(Answer)
Answer is A. first one...
P = -3
G = 3
P = -G = -(3) = -3
Let's compare the cost of both the centers.
<u>Cost of Center A:</u>
One time charge of $495 in one year.
<u>Cost of Center B:</u>
- Flat $25 dollar sign up fee
- $15 per month, so
dollars a year - $5 per aerobic class, so
dollars a year (given that Billy goes to class once a week) (<em>Note: There are 52 weeks in a year</em>)
Total cost =
dollars
Hence, Center B would cost
dollars cheaper.
ANSWER: Least expensive club for Billy to use for a year is Center B
