If H is the circumcenter of triangle BCD, find each measure. CD, CE, HD, GD, HG, HF
Levart [38]

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

Which function is equivalent to the inverse of y=sec(x)
kipiarov [429]
From the identity:

sec(x)= \frac{1}{cos(x)}


f(x)=sec(x)= \frac{1}{cos(x)}

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

thus, cos[g(x)]= \frac{1}{x}

g(x)=cos^{-1} (\frac{1}{x})


Answer: b. g(x)=cos^-1(1/x)

Can someone help me with this it's making no sense to me
Dafna11 [192]

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.
