Answer:
3.43
Step-by-step explanation:
To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
Let d be mile driven. Then,
30+0.25d>40+ 0.1d
.15 d>10
d>66.667
you must drive at least 66 and 2/3 miles before the second country is cheaper
Given equation is 
.
Now we need to find about what are the key aspects of the graph of , where b is a real number.
We know that square of any number is always positive.
then 
must be a positive number.
So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by units as compared to the graph of parent function
