Suppose <br> f '(x) = xe^−x^2

iogann1982 [59]

<h3>Answers:</h3>

(a) The function is increasing on the interval (0, infinity)
(b) The function is decreasing on the interval (-infinity, 0)

=======================================================

Explanation:

You should find that the derivative is entirely negative whenever x < 0. This suggests that the function f(x) is decreasing on this interval. So that takes care of part (b).

The interval x < 0 is the same as -infinity < x < 0 which then translates to the interval notation (-infinity, 0)

Similarly, you should find that the derivative is positive when x > 0. So the function is increasing on the interval (0, infinity)

A carpenter is framing a wall that is 8 feet high and 15 feet long. If the carpenter wants to be sure that the sides of the wall

Ad libitum [116K]

If you cut the rectangle (the wall) diagonally, you get two congruent triangles. The measurements of the sides of one the triangles is 8, 15 and x. There is a pythagorean triples 8, 15, 17 so x has to be 17. if you dont know the triple you can do a^2 + b^2 = c^2 8^2 + 15^2 = c^2 c = 17

the diagonal of wall should be 17

You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can you do this?

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Once you give 1 candy to each of the 4 kids, you will have 3 remaining. The number of ways those can be distributed to 4 kids is given by ...

(n+k-1)C(n)

where n is the number of candies, and k is the number of kids. "aCb" is the number of ways a can be taken b at a time:

aCb = a!/(b!(a-b)!)

For n=3 and k=4, this is ...

(3+4-1)C(3) = 6C3 = 6!/(3!·3!) = 20

There are 20 ways to distribute 7 candies to 4 kids so that each kid receives at least one.
