has critical points where the derivative is 0:

The second derivative is

and
, which indicates a local minimum at
with a value of
.
At the endpoints of [-2, 2], we have
and
, so that
has an absolute minimum of
and an absolute maximum of
on [-2, 2].
So we have



Answer: 3000 + 900 + 60 + 1
Answer:
Sailboat A won the race, and it was going 8 feet per second.
Step-by-step explanation:
Sailboat A was traveling at 40 feet per every 5 seconds, so, to find how many feet it was going per second, we would do 40 feet/5 seconds, which is 8 feet.
Sailboat B was traveling at 56 feet per every 8 seconds, so we use the same method. 56 feet/8 seconds is 7 feet.
So, Sailboat A won because it was going faster! :)
You can verify this by plugging the numbers into the Pythagorean theorem,

, where c is the hypotenuse (the longest side, in this case 53).
So it would be:

The equation is true.
2809 = 2809
Answer:
7
Step-by-step explanation:
x * x = 7x
7 x 7 = 7 x 7
49 = 49
so if x is 7, the equation is true...
