Answer:
A
Step-by-step explanation:
in x<-4 the derivative is positive so the function is increasing.
in x>-4 the derivative is negative so the function is decreasing
increasing in (-infinity,-4)
decreasing in (-4,infinity)
1/6 of an hour= 10 because 60mins=1hour & 60/6=10 so the sailboat travels 2 1/2 miles in 10 mins. So the complex fraction would be 2 &1/2 over 10. Hope it helps!
The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
Thats a rectangle .........
