Willie Crash was out Sunday flying in his spaceship. As he approached Mars, he changed his mind, and decided that he did not wish to visit that planet and fired his retro-rocket. The spaceship slowed down, and if all went well (or did it?), stopped for an instant then started pulling away. While the rocket motor was firing, Willie's distance, d, from the surface of Mars depended by a quadratic function on the number of minutes, t, since he started firing the retro-rocket. Willie finds that at time t= 1, 2, and 3 minutes, his distances were d= 425, 356, and 293 kilometers, respectfully. what is the INDEPENDENT variable? (t or d)

what is the DEPENDENT variable? (t or d)

what does the INDEPENDENT variable represent? 1. the distance D from the surface of Mars OR 2.The number of minutes Titi since he started firing the retro-rocket

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
