For the years 0 through 24 the profit is either zero or a positive number, so the shop is not in debt for those years.
Answer: A. [0, 24]
Here you go, you’ll probably have to re-word it for your answer but that was the simplest way to answer it for me.
Answer:
-1
Step-by-step explanation:
Firstly + and (-) become - and again same thing will happen

Alright so, let’s break this down.
To find the first coordinate you need to solve the first equation
To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3
The answer to that is the solution to the first equation, or the first coordinate.
For the second one, you know x has to be negative because the solution is negative
2x is going to have to equal -20
-20/2 gets you the solution
Remember that it will be negative
You now have both of the coordinates
You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c
Answer:
sin(mod(π/2 -x, π) -π/2) . . . . except undefined at odd multiples of π/2
Step-by-step explanation:
The derivative of the modulus of the cosine function is the same as the derivative of the cosine function between cusps: -sin(x), for -π/2 < x < π/2.
There are many ways to make that pattern repeat with period π. one of them is this:
(d/dx)|cos(x)| = sin(mod(π/2 -x, π) -π/2) . . . . . except undefined at x=π/2+kπ, k any integer
___
The graph shows the modulus of the cosine function along with its derivative as computed by the graphing calculator and its derivative as defined above.
