<span>So we want to know what the area of a circular bread is if we know the diameter d=11 inches. First the diameter is equal to 2 radii, d=2r, so our radius r=11/2=5.5 inches. Now we can calculate the area. Formula for the area is A=pi*r^2. After we input our numbers we get the area A=94.985inches^2. Rounding the answer to the nearest hundreth: A=94.98 inches ^2</span>
Step-by-step explanation:
Start by finding when the populations become equal.
C = R
1000e^(0.1t) = 50e^(0.5t)
Divide both sides by 50.
20e^(0.1t) = e^(0.5t)
Divide both sides by e^(0.1t).
20 = e^(0.4t)
Take natural log of both sides.
ln 20 = 0.4t
Multiply both sides by 2.5
t = 2.5 ln 20
t ≈ 7.5

Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
