3 0

Answer:

It will be worth $128.

Step-by-step explanation:

After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

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:

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