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.
The initial number was 3.915 and doubled to 7.830
Regression equation y = 3. 915(1. 106)x
7.830=3.915(1.106)D
we have to find the value of D.
This is the concept of algebra,
suppose the initial number was x, and the new number is 2x.
The constant rate of growth is r and time is D,
Then,
what is the function representing growth?
from our choices the equations that represents the information above will be:
7.830=3.915(1.106)D
and
7.830=3.915(2)D
Therefore
from both equations we see the initial number was 3.915 and doubled to 7.830
