Answer:
2.64 km
Step-by-step explanation:
The first step is to calculate the distance in meters
= 24×110
= 2640 meters
1km= 1000 meter
2640 meters to kilometer
= 2640/1000
= 2.64 kilometers
Hence the distance is 2.64 km
Answer:
y = 55 + 8x
255 gallons
Step-by-step explanation:
Let x be the number of minutes the tank is being filled with water.
A water tank
- Already contains 55 gallons of water;
- Water flows into the tank at a rate of 8 gallons per minute;
- In x minutes, 8x gallons flow into the tank.
Hence, the tank will contain 55 + 8x gallons of water.
If y gallons is the volume of water in the tank after x minutes, then
y = 55 + 8x
When x = 25, then
Parametize C of the line integral as
from 0<=t<1 then
which means by substituting x with e^t and y with and dx with e^t dt we get
by adding exponents
