Your picture has several issues.
- x is not defined. It appears to be the number of apartments rented.
- R(x) is defined two different ways. The first way, it looks like it is the revenue from a single apartment. The second way, it looks like it is the revenue from the entire apartment complex.
- The derivative is in error. It should be -20x +2000. In any event, this is not the derivative you want. You're not trying to maximize revenue; you're trying to maximize profit.
- It might be useful to write an equation for profit: P(x) = R(x) -200x = -10x² +1800x. Then when you go to maximize it, your derivative will be P'(x) = 0 = -20x +1800 ⇒ x = 90.
Your answer is correct, but the path you followed to get there has a few potholes.
Answer:
Step-by-step explanation:\
B is the most correct because it provides when the outiside tempature decreases the gas temperature increases as shown in the plot data on B the other ones are not correct!
please mark brainliest and sorry for what the other user put just ignore him i just had a problem with him on another question!
V = bh....divide both sides by b
v/b = h <===
Answer:
2/3 > 3/8
Step-by-step explanation:
2/3 > 3/8. This is because 2/3 as a decimal is 0.6666667 while 3/8 as a decimal is 0.375. 2/3 is therefore more than 3/8.
Answer:
f(x) = 2+√x
Step-by-step explanation:
To shift a function up by k units, add k to the value of the function. Here, you want to shift the square root function up 2 units, so you add 2 to the square root:
f(x) = 2+√x
