Calculate the circumference of the two semi circles, which equals a full circle. Then add the two sides of the track.
 Circumference is pi x diameter = 3.14 x 22.8 = 71.592, so, you would need to add 71.592 + 49.2 + 49.2  = 169.992 meters, and that would be the length of one lap of the track.

Step-by-step explanation:

oh, come on. you can just use common sense.

a local minimum is a point where the curve goes down to, and then turns around and starts to go up again. that point in the middle, where it turns around and does not go down any further, is the minimum.

for the maximum the same thing applies, just in the other direction (the curve goes up and turns around to go back down again).

a)

the local minimum values (y) are

-2, -1

b)

the values of x where it had these minimum values are

-1, +3

How do you subtract a whole number and a mixed fraction
fredd [130]

Answer:

"The easiest way would be to turn the whole number into a fraction so for instance if the number was 2 it would become 16/8. You can then easily subtract 16/8 from 1/8 which would equal -15/8"(//answers.yahoo.com/).
