Answer:
Option C.
Step-by-step explanation:
It is given that,
Service cost = $10 per month
Free rental DVD = first 3
Rental after first 3 DVD = $2 per month
We need to find the expressions models for the total amount that Tharun pays, in dollars, in a month when he rents d, DVDs where d>3.
Fixed cost = $10
Rental apply after first three DVD. So,
Variable cost = $2(d-3)
Total cost = Fixed cost + Variable cost
Therefore, the required expression is C.
The cube has the greatest surface area.
2 areas because there isnt an equal amount of elm trees and oak trees to be planted
Answer:
2 hrs
Step-by-step explanation:
Boat moving rate= 11 mph
river's current flow rate= 3 mph
By adding both of them, we get
11 + 3 mph=14 mph
Now,
Time taken= distance travelled/ velocity
= 27/14
= 2 hrs
x ^ 2 - 18 = 0
For this case, the first thing you should do is rewrite the expression:
x ^ 2 - 18 = 0
x ^ 2 = 18
The solutions for this case are:
x1 = root (18)
x2 = -raiz (18)
Therefore the answer is:
2 solutions of real numbers.
