Pi is defined as the ratio of the circumference of any circle to its diameter. As all circles are similar and therefore proportional in dimensions, pi is therefore always the same for all circles and is constant
(603+607)/2 = 1210/2 = 605
This is the concept of applications of volume. We are required to calculate BTUs per cubic foot. This will be given by the formula:
(BTU)/volume
Total BTU=15*750=11,250
(assuming the bus is a perfect cuboid) volume of the bus will be;
volume=length*width*height
=38*8.5*6.25
=2018.75 ft^2
Thus the BTUs per foot will be:
11250/2018.75
5.57 BTUs/ft
The function that models exponential growth is:
P(t) = P0*(1 + r)^t, where
P0 = P(0) is the initial value of P
r is the growth rate as a decimal
In our case we have:
P(0) = 2800
r = 0.035 or 3.5%
P(t) = 2800*(1 + 0.035)^t
P(t) = 2800*(1.035)^t
The same exponential function written using y and t is:
y = 2800*1.035^t.

Answer:
We can boldly say, if the car dealer is hoping to sell 40 cars, the model predict he should run about 15 commercial this week.
Step-by-step explanation:
To start with solving this question, we try to define the parameters in the question:
So we have:
X = ? numbers of cars sold
Y = ? of commercial
X1 = 30.5
SX = 4.2
Y1 = 12.4
SY = 1.8
r = 0.56
Now, recalling the equation for slope and intercept
If we apply them in this instance,
we have:
Foe Slope b1 = r . SY / SX and For intercept = b₀ = Y1 - b , X1
b1 = 0.56 (1.8) / 4.2 b₀ = 12.4 - (0.24)(30.5)
b1 = 0.24 b₀ = 5.08
Where:
Y¹ = b₀ + b1 X
Y¹ = 5.08 + 0.24 X
Therefore, ? number of commercial = 5.08 + 0.24 cars
where:
? number of cars = 40
Therefore,
5.08 + 0.24 (40)
14.68
Hence, we can boldly say, if the car dealer is hoping to sell 40 cars, the model predict he should run about 15 commercial this week.
