I don't understand how to solve this pls help
Charra [1.4K]

the sine function is a many-to-one function and therefore has no inverse function.

However if the domain is restricted to -90° ≤ x ≤ 90°

Then the function is one-to-one for this domain

Thus, sin^{-1} x is defined as the angle such that - π/2 ≤ x ≤ π/2

5π/6 is therefore outwith the domain

the answer is C, 369

Step-by-step explanation:

HELLO THERE!

(:

This is a problem that looks harder then it seems, First determine the cost of each item he is trying to buy. Then figure out the number of dollars he has to spend. Once you have figured that out you divide the cost into how much he has.

For example.
John has 10 dollars. He wants to buy pencils. Each pencil will cost john 2 Dollars. How many can he buy?

By dividing the cost of the pencils = 2 into the number of dollars he has 10 Divided by 2, we get 5. 

Now it's your turn. Divide the number he has to spend by the price of the items. This will get you your answer! 
Hope this helped!
