If sin 0 = 7/25, find csc 0

kipiarov [429]

Answer:

$csc(\theta)=\frac{25}{7}$

Step-by-step explanation:

We know that:

$sin(\theta)=\frac{7}{25}$

And we want to find:

$csc(\theta)$

Remember that there is a trigonometric identity that relates the $sin(\theta)$ function with the $csc(\theta)$ function

$csc(\theta)=\frac{1}{sin(\theta)}$

Then if $sin(\theta)=\frac{7}{25}$ this means that:

$csc(\theta)=\frac{1}{\frac{7}{25}}$

Finally:

$csc(\theta)=\frac{25}{7}$

month 2 0.96 0.04 1

month 3 0.808 0.192 1

total x = 0.9 y = 0.10 1

x = 270 / 300 = 0.90

y = 30 / 300 = 0.10

If f(x) = 9x – 8, which of the following is the inverse of f(x)?

zheka24 [161]

Answer: $f^{-1}$ (x) = $\frac{x+8}{9}$

Step-by-step explanation:

f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes

y = 9x - 8 , then make x , the subject of the formula ,

9x = y + 8

x = $\frac{y+8}{9}$

Finally , replace x , with $f^{-1}$ (x) and y with x , so we have

$f^{-1}$ (x) = $\frac{x+8}{9}$
