Answer:
See explanation below.
Step-by-step explanation:
a) c(0) = 10
Here, t = 0 and c(0) = 10
At 8 A.M., there are 10 customers.
b) c(6) = c(7)
6 hours after 8 am is 2pm
7 hours after 8 am is 3pm
They are equal. So it means
There are the same number of customers at 2pm and at 3pm
c)
c(k) = 0
There are no customers, k hours after 8 am
d)
c(4) > c(3)
4 hours after 8 am is 12pm
3 hours after 8 am is 11am
This means:
The number of customers at 12pm is greater than the number of customers at 11am
Answer:
Step-by-step explanation:
a. The area of a rectangle is width * length. The width is 5x, and the length is 7x-2. This means the area is 5x*(7x-2). Distributing the 5x, we find that the area of the rectangle is 35x^2-10x.
b. To find the area when x is 4, we plug x=4, so 35*4^2-10*4=560-40=520.
c. same as above, we plug x=7, and get 1645 as our area.
Answer:
5
Step-by-step explanation:
180-133=47
