Step 1
<u>Find the equation in function notation</u>
Let
h-------> the number of hours
y-------> the function for the walker fee in dollars
we know that
the hourly rate is
in this linear equation
the independent variable is the variable h
the dependent variable is the variable y
<u>Convert to function notation</u>
Let
Step 2
Find how much does the dog walker charge for a 45 minute walk
Convert the time in hours
substitute in the equation
For
therefore
<u>the answer is</u>
the dog walker charge for a 45 minute walk
<u>Statements</u>
Step 3
<u>The dependent variable is the number of hours true or false</u>
The statement is false,
because the independent variable is the number of hours and the dependent variable is the walker fee in dollars
Step 4
<u>The function for the walker fee is f(h)= 30h+6 true or false</u>
The statement is True --------> see the Step 1
Step 5
<u>The dog walker charges $22.5 for a 45 min walk true or false</u>
The statement is False
Because the dog walker charges for a 45 minute walk
For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.
We must find the . Then, we look for the angle whose sine is
.
We have to, by definition:
So, we have to:
