Answer:
12 feet
Step-by-step explanation:
A driveway is rectangular in shape.
Therefore we can calculate the area using the formula;

From the question;
The area,A=96 feet square
The width, W=8 feet
We substitute this values into the formula to find the length, L.
This implies that

Dividing through by 8.


Hence,the length of the driveway is 12 feet.
40(60/100) 4(6/10) =24/10 = 2.4
B x h = 8 x 10 = 80. 80 divided by 2 is 40 so 40cm
Answer:
The rate of change of temperature is 1.29 degree Celsius per second.
Step-by-step explanation:
We are given the following information in the question:
The temperature at a point (x, y) is T(x, y), measured in degrees Celsius where x and y are measured in centimeters.


We have to find the rate at which the temperature is rising on the bug's path after 14 seconds.
At t = 14 seconds, we have,

To find rate of change of temperature, we differentiate,

Thus, the rate of change of temperature is 1.29 degree Celsius per second.
