It took me a minute, but I understand what it wants you to do.

a^2+b^2=c^2

Find the missing length on that one triangle to the left.

62^2+b^2= 99.2^2

Square the numbers.

3844+b^2= 9840.64

Subtract 3844 on both sides.

b^2= 5996.64

Square root it.

b= 77. 437975 round down to b= 77.4

Now, we can find the length of the other missing side. (x+2)

77.4^2+b^2= 112^2

5990.76+b^2= 12,544

Subtract 5990.76 on both sides.

b^2= 6553.24

Square root it.

b= 80.952085, round to b=81

Now, plug that in.

(x+2)= 81

Subtract 2 on both sides.

x=79 (about)

I hope this helps! Make sure to check my work.

Let a set of $n$ elements.
We can find $n!$ (factorial) of the $n$ element.
However, combination of the element lead to less than $n!$ possibilities.
(combining like adding or multiplying)
So the proposition is false.

Help please I don’t understand this math problem

Semenov [28]

If you divide (6x +3) by (x +1) you get some quotient and some remainder. You can do it a variety of ways, including synthetic division and long division. The method used here is to rewrite 6x+3 as a multiple of x+1 with some constant term added.
.. 6x +3 = (6x +3) +3 -3
.. = (6x +3 +3) -3
.. = (6x +6) -3
.. = 6(x +1) -3

Now, you can divide this by (x +1) and you have
$\frac{6x+3}{x+1} = \frac{6(x+1)-3}{x+1} = \frac{6(x+1)}{x+1} +\frac{-3}{x+1} = \frac{-3}{x+1}+6$
Then the boxes can be filled from ...
$g(x)=\frac{6(x+1)+(-3)}{x+1}=\frac{-3}{x+1}+6$

You know that
.. f(x) +6
represents a translation of f(x) by 6 units up
And you know that
.. f(x +1)
represents a translation of f(x) by 1 unit left

So, you can figure that
.. g(x) = f(x +1) +6
will represent a translation of 1 unit left and 6 units up of f(x) = -3/x.

If a figure has been dilated by a scale factor of 1/3 which transformation could be used to prove the figures are similar using

Vlad [161]

Answer:

A translation because it can map one angle onto another since dilation preserve angle measures of triangles.

Step-by-step explanation:

In order to prove the two triangles by AA postulate, we must meet the conditions of the AA similarity postulate that says-

"Two triangles that have two congruent angles are similar".

So, we have to prove at least two corresponding angles of the given two triangles congruent.

One triangle is the dilation of the other. When we dilate a figure, the things that change are:

1. Lengths - Dilation changes the lengths of each side of the figure.

2. Size - Dilation changes the size of the figure.

When we dilate a figure, the things that do not change are:

1. Orientation - Dilation preserve orientation

2. Angles - Dilation preserves the interior angles of the figure.

So, the transformation that will preserve both orientation and angles will be used to prove triangles similarity using AA postulate.

A translation because it can map one angle onto another since dilation preserve angle measures of triangles.

A translation only moves the entire figure and thus we can overlap the vertices of the triangle and find whether the angles are congruent or not.

With the translation we will prove that other pair of angles of the triangles are congruent and thus the two triangles can be proved similar using the AA similarity postulate.

Makovka662 [10]

Answer:

10,000

Step-by-step explanation:

The link capacity is 10^9 bps; the link usage is 10^5 bps per user, so the number of users that can be supported is ...

(10^9 bps)/(10^5 bps/user) = 10^4 users
