Hello!
First you have to find out how many hours she works
She worked 8 hours a day for 5 days
8 * 5 = 40
Divide this by the money she earned
720 / 40 = 18
The answer is $18 an hour
Hope this helps!
Answer:
5/4
Step-by-step explanation:
To do this you must know that by definition secant is:

Furthermore:

Based on this information we know that 3 = opposite and 5 = hypotenuse. Assuming this is a right triangle we can determine the adjacent side by Pythagorean Theorem.

Where c is the hypotenuse, a is adjacent and b is opposite. Therefore,

And so the adjacent side of this triangle is 4. Going back to the definition of secant we can now know that:

Answer:
Shown in the picture
Step-by-step explanation:
A:
Set the value of x to "5" and "30" to find the corresponding values of y (i.e. the altitudes of the plane at 5 or 30 minutes after beginning descent).
B:
Use the the same method to determine the set of coordinates (/ordered pairs) at each of the values for x given in part B of the question.
C:
The initial value is simply the starting value of y, or in other words, the altitude at which the plane begins to descend in this context;
So it will be 0 mins after the beginning of descent of the plane, i.e. when x = 0, therefore the answer is (0, 28000) as an ordered pair or simply 28000 ft.
D:
Rate of change is a fancy or more technical way of referring to the gradient of a function;
In this case of the context of a plane descending, it refers to the change in altitude over time;
This can be calculated using any two ordered pairs (or coordinates as I call them) using the formula of the difference in the y values divided by the difference in the x values.
Since 340 % van be written to 3.4, just use 88.8 to divide it by 3.4, so the answer should be 26.1176470588, if ur question needs you to round up to a number of decimals, do it
