Answer with explanation:

Dilation in general, is a type of transformation that produces a same image like the original image but with different size.

With respect to functions, when a function/graph is stretched away from an axis or shifted towards an axis, then it is called dilated.

Though the function retains the same shape even when it is multiplied by any number. During this process, the functions dilate for sure, but at the same time keep its original shape.

When a function is multiplied by a number, the shape of the graph will retain its basic shape, though stretch or compress in different directions. ... This is the second of five activities about transformations of functions, focusing on: translations,dilations, reflections, all transformations, and inverses of functions.

Find the measure of each angle that is labeled on the diagram shown below.

Elza [17]

Lets take it in order:

1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5

Answer:

-5

Step-by-step explanation:

The equation for slope is:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

We can plug in the given coordinates into the equation:

$Slope=\frac{-2-3}{3-2}=\frac{-5}{1}=-5$

Urgent help please

rosijanka [135]

Let's assume the frequency of sound be f and wave length is w.

Given that, the frequency of sound varies inversely as the wavelength.

So, we can set up an equation as following:

f*w = k Where k= constant of variation.

Other information is, the frequency of a musical note is 276 cycles per second when the wavelength is 1.2m.

So, next step is to plug in f = 276 and w = 1.2 in the above equation to get the value of k.

276 * 1.2 = k

So, k = 331.2

Next step is to plug in k = 331.2 in the above equation. So,

f * w = 331.2

Now we need to find the wave length : w when frequency : f = 600.

Therefore,

600 * w = 331.2

$w = \frac{331.2}{600}$

So, w = 0.552

Hence, the wave length is 0.552 m.

Hope this helps you!.
