Answer:
10 square units
Step-by-step explanation:
We want to find the area under the curve
from x=1 to x=3.
We use definite integrals to find this area.

We integrate to obtain:

We evaluate the limits to get:


Therefore the area under the curve from x=1 to x=3 is 10 square unit.
Answer:

Step-by-step explanation:
Try to get x alone on one side
Add nine to both sides
18x - 9 = 5 + 12x
+ 9 + 9
Subtract 12x from both sides
18x = 14 + 12x
-12x -12x
Now that you have x alone on one side divide both sides by 6
6x = 14


Answer: 12
Step-by-step explanation: To figure this out you have to subtract 25 by 13
25
- 13
= 12
Answer:
Bob will spend on ice cream for the team $20.25
Step-by-step explanation:
Hello!!!
In this problem we are expected to solve for the total amount that Bob will spend to buy
8 players ice cream cookies and
5 players ice cream cones
let us calculate as follows
Cost of ice cream cookies for 8 players = 8*1.75= $14
Cost of ice cone for 5 players = 5*1.25= $6.25
Total cost = $14+ $6.25= $20.25
