Which distance formula shows a direct variation? 1. D=50t 2. D=16t^2 3. D= r×t

1 answer:

7 0

The answer could be choice 1 or 3.

With direct variation, we simply multiply one variable to get the other variable.

In #1, we are multiplying t by 50.

In #3, we are multiplying t by r.

In both cases, t is just be multiplied by a number.

The foot of a ladder is placed 7 meters from a wall. If the top of the ladder rests 9 meters up on the wall, how long is the lad

nekit [7.7K]

We can find the length of the ladder by squaring the known digits, adding them, and finding the square root of the sum. This would mean our first equation, after squaring, will look like this:

49+81=130

Now that we have <em>c</em> squared, we can go through and find the approximate square root, which is 11.4. That would mean the ladder is 11.4 meters long.

Simplify the difference.

mr_godi [17]

$\displaystyle\frac{n^2-10n+24}{n^2-13n+42}-\frac{9}{n-7}=\frac{(n-6)(n-4)}{(n-6)(n-7)}-\frac{9}{n-7}\\\\=\frac{n-4}{n-7}-\frac{9}{n-7}=\frac{n-4-9}{n-7}\\\\=\frac{n-13}{n-7}$

The last choice is appropriate.
