Answer:
H is the circumcenter of triangle BCD
- CD = 2FD = 2*32 = 64
- CE = BE = 26
- HD = HC = 33
- GD = 1/2BD = 1/2(58) = 29
- HG = √HD ²-GD² = √33²-29² = 2√62 ≈ 15.75
- HF = √HD ²-FD² = √33²-32² =√65 ≈ 8.06
Answer:
all real numbers greater than or equal to 2
which is [2, infinite)
From the identity:


the inverse of f is g such that f(g(x))=x,
we must find g(x), such that
![\frac{1}{cos[g(x)]}=x](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bcos%5Bg%28x%29%5D%7D%3Dx%20)
thus,
![cos[g(x)]= \frac{1}{x}](https://tex.z-dn.net/?f=cos%5Bg%28x%29%5D%3D%20%5Cfrac%7B1%7D%7Bx%7D%20)

Answer: b. g(x)=cos^-1(1/x)
Answer:
The most reasonable is 2 h
Step-by-step explanation:
If you see the graph is decreasing in hours while is increasing in years. When a person is 45 years the amount of daily physical activity is 3 hours, so a person that is 50 years needs to do less than 3 hours a day and the only option less than 3 hours is 2 hours.
