Answer:
21600 letters
Step-by-step explanation:
There are 5400 seconds in 1.5 hr, so there are 135 40-second intervals. So, 160 messages multiplied by 135 time intervals is 21600 letters.
The coordinates of the image of triangle CAT located at C(-2, 2), A(4, -2), T (1, 1) after a dilation with a scale factor of 4 are:

<h2 /><h2>Explanation:</h2>
In this case, we have a triangle CAT that is located at the following points:

When dilating objects we enlarge or reduce the size of the object. The scale factor tells us how much larger or smaller the object will become. For a scale factor greater than 1, the object will increase in size and for a scale factor less than 1, the object will decrease in size meaning that the resulting object will be similar to the original one. So, for a point P and scale factor k, the image will be P':

Here we'll assume the center of the dilation at the origin, so the coordinates of its image after a dilation with a scale factor of 4 are:
