Answer:
Step-by-step explanation:
Let be an acute angle.
To solve: , we take the sine inverse of both sides to obtain:
Recall composition property of a function and its inverse function.
We apply this property to the left hand side to obtain;
We now use our scientific calculator to obtain;
We round to the nearest tenth to obtain;
Answer:
percentage change=25% .
Step-by-step explanation:
Given : $15.60 to $11.70 .
To find: What is the percent change .
Solution: We have given that $15.60 to $11.70 .
Change = final value - initial value .
Change = $15.60 - $11.70
=$3.9
percentage change =
=
= .
On dividing both number by 3
percentage change=.
percentage change=.
percentage change=25% .
Therefore, percentage change=25% .
The difference is the result of a subtraction problem.
We are given two values that are being subtracted: 54 and a number, represented by
So, represent this mathematically with .
