Water coming out from a fountain is modeled by the function f(x) = −x2 + 8x + 2 where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds.What does the average rate of change of f(x) from x = 1 to x = 4 represent?

Answers

Answer 1
Answer: Average rate of change of f(x) from x = 1 to x = 4 represents the average speed with which the water is falling between the first second and the fourth second.

Evaluate the integral: \[\int\limits_{}^{}ye ^{0.2y}dy\]
The problem we are having is the antiderivative of
\[e ^{0.2y}.\] We decided to split the problem into:
u = y
\[uv = e^{0.2y}\]
We just aren't sure where to go from here. Help?

Compute the odds in favor of rolling a sum of 10 in a single roll of two fair dice

Answers

There are 6 possibilities for the outcome of one cube.  For each of those . . .
There are 6 possibilities for the outcome of the other cube.

Total possibilities for the roll of 2 cubes = (6 x 6) = 36 outcomes.

Ways to roll a sum of 10:
4 . . . 6
5 . . . 5
6 . . . 4
Three possibilities.

Probability of rolling a 10 = 3/36 = 1/12 = 8 and 1/3 percent 

Odds in favor of success = 1 in 12 , or    1 to 11 . (11 to 1 odds of failing.)
