60*8= 480+20+10+15+40=565/4=141= 2 hours and 21 min
141+148=289/2=145=
2 hours and 25 min is the next flight
Answer:
20 = 4n
n = 5
Step-by-step explanation:
Given that :
Number of gifts Keiko wrapped = 20
Let number of gifts wrapped by Henry = n
Keiko wrapped 4 times as many gifts as Henry
Hence,
20 = 4n
The equation that relates the number of gifts wrapped is :
20 = 4n
To obtain n ;
Divide both sides by 4 to isolate n
20/ 4 = 4n / 4
5 = n
Hence,
n = 5
Answer:
A.This is the graph of the greatest integer function
E. f(-3.4)=-4
Step-by-step explanation:
The graph shown in the attachment is the parent greatest integer function.
f(x)=[x]
This takes any integer as an input and the output is the greatest integer less than the input.
For instance
f(4.9)=4 because 4 is the greatest integer less than 4.9
f(-3.4)=-4 because -4 is the greatest integer less than -3.4
This graph is not one-to-one because more x-values can correspond to one y-value.
For instance f(3.4)=3 and f(3.9)=3
The correct options are A and E
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.
