Answer:
Area of circular trail = 7.1 square miles
Step-by-step explanation:
Given that:
Distance covered by Mr. Baker = 6 miles
As this distance is of both sides, we will divide it by 2 which will give us the diameter of the circle.
Distance of one side = 6/2 = 3 miles
Diameter = 3 miles
Radius = 3/2 = 1.5 miles
Area of circle = 
Area of circle = 
= 3.14 * 2.25
Area of circle = 7.065 = 7.1 square miles
Hence,
Area of circular trail = 7.1 square miles

Answer:
The value of the stock can be found by: x × 1.26.
Step-by-step explanation:
The value of the stock in year one can be found by multiplying x by 1.4. This will represent a 40% increase in value. The following year, the stock decreases in value by 10%; this is represented by multiplication by 0.9. For example, if the value of the stock was $5:
5 × 1.4 = 7 (A 40% increase in value)
(5 × 1.4) * 0.90 = 6.3 (A further 10% decrease in value)
Rather than writing out the long version, we can simplfify by multiplying 1.4 by 0.9 to get 1.26 .We can also replace 5 with x to get a more general equation.
Critical values are values where f'(x)=0 and the bounds of a function. Thus, let's solve for f'(x)!
f(x)=2x^3-3x^2+3x+8
f'(x)=6x^2-6x+3
Now let's set f'(x)=0
0=6x^2-6x+3
0=2x^2-2x+1
As it turns out, 2x^2-2x+1 isn't factorable!
This saves me some time because this means there are no critical numbers!
