Answer:

D. m = \sqrt{3}, n = 1

Step-by-step explanation:

The triangle given is a 30-60-90 triangle. This means that the longer side of the leg is x\sqrt{3} (m), the shorter side of the leg is x (n), and the hypotenuse is 2x.

The hypotenuse is already given as 2, and since the hypotenuse is 2x, to find the shorter side (n), just divide by 2, giving you n = 1.

Now onto the longer side (m); it's represented by x\sqrt{3}, and since x is just 1, all you do is put x in front of \sqrt{3}.

But in this case, x is just 1, so it's like "imaginary," and doesn't need to be written out.

If f(x) is an antiderivative of g(x), and g(x) is an antiderivative of h(x), then
Goryan [66]
If f(x) is an anti-derivative of g(x), then g(x) is the derivative of f(x). Similarly, if g(x) is the anti-derivative of h(x), then h(x) must be the derivative of g(x). Therefore, h(x) must be the second derivative of f(x); this is the same as choice A. 

I hope this helps.

On Dan's eReader, 2/3 of the books are fiction. Of the fiction books,4/5 are mysteries. What fraction of the books on Dan's eRea
Nitella [24]

Answer:

Step-by-step explanation:

Let's take a real situation. Suppose he has 1500 books in total

2/3 of them are fiction. Of means multiply.

them = 1500

2/3 * 1500 = 3000/3 = 1000

Now of the one thousand fiction books 4/5 of them are mysteries.

4/5 * 1000 = 4000/5 = 800.

Now let's see what happens when we just do this by answering the question directly.

2/3 * 4/5 = 8/15 This has the meaning that 8 out of every 15 books = mysteries.

Try this on the 1500 books.

8/15 * 1500 = 9000/15 = 800. So the answers are the same and the answer the computer expects should be 8/15 or 0.533333333

Just to check, does 0.5333333 * 1500 = 800? Try it.

Find the coordinates of the midpoint of the segment whose endpoints are H(10, 1) and K(4, 7).
Oliga [24]

The formula of a midpoint of a segment AB:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have:

H(10; 1); K(4; 7)

substitute:

M_{HK}\left(\dfrac{10+4}{2};\ \dfrac{1+7}{2}\right)\to M_{HK}\left(\dfrac{14}{2};\ \dfrac{8}{2}\right)\to M_{HK}(7;\ 4)

Answer: (7, 4)

What is the definition of parallel lines?
Fittoniya [83]
<span>Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. Any line that has the same slope as the original will never intersect with it.
