Answer:
581
Step-by-step explanation:
<u>Population of Grizzlys</u>
1970 >>> 270
2005 >>> 115% INCREASE
We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):
115/100 = 1.15
So, that would be now:
1.15 * 270 = 310.5
Increasing, we get:
270 + 310.5 = 580.5
We round to 581
In 2005, the population was about 581

Answer:
17) MC(x) = 35 − 12/x²
18) R(x) = -0.05x² + 80x
Step-by-step explanation:
17) The marginal average cost function (MC) is the derivative of the average cost function (AC).
AC(x) = C(x) / x
MC(x) = d/dx AC(x)
First, find the average cost function:
AC(x) = C(x) / x
AC(x) = (5x + 3)(7x + 4) / x
AC(x) = (35x² + 41x + 12) / x
AC(x) = 35x + 41 + 12/x
Now find the marginal average cost function:
MC(x) = d/dx AC(x)
MC(x) = 35 − 12/x²
18) x is the demand, and p(x) is the price at that demand. Assuming the equation is linear, let's use the points to find the slope:
m = (40 − 50) / (800 − 600)
m = -0.05
Use point-slope form to find the equation of the line:
p(x) − 50 = -0.05 (x − 600)
p(x) − 50 = -0.05x + 30
p(x) = -0.05x + 80
The revenue is the product of price and demand:
R(x) = x p(x)
R(x) = x (-0.05x + 80)
R(x) = -0.05x² + 80x
I think number 1 is 15 and number 2 is 80. Have a nice day!
