Tanya's rotation maps point K(24, –15) to K'(–15, –24). Which describes the rotation? 90 degrees clockwise rotation 270 degrees
alexira [117]

Answer:

A. 90 degrees clockwise rotation

Step-by-step explanation:

Of we have a coordinate axis (x,y), if this axis is rotated 90° clock wide, the resulting coordinate of the pre-image will be the coordinate (y -x). Note that the coordinates was swapped and then the new y coordinate negated.

Given the coordinate K(24, -15). If we rotate this clockwisely, first we swap the coordinate axis to have (-15, 24)

Them we will negate the new y coordinate axis to have;

K'(-15, -24)

Therefore the correct answer is 90° clockwise rotation.

**MARKING BRAINLIEST PLEASE HELP**
raketka [301]

Answer:

\text{1. } v=16t+\frac{h-c}{t},\\\text{2. }90\:\mathrm{ft/s}, \\\text{3. Cannot be determined}

Step-by-step explanation:

1. The initial equation given to us is h=-16t^2+vt+c. Rearranging the equation to isolate v, we have:

vt=16t^2+h-c,\\\boxed{v=16t+\frac{h-c}{t}}

2. Using the equation we rearranged in part 1, we can substitute given values:

v=16(3)+\frac{131-5}{3},\\v=48+42=\boxed{90\:\mathrm{ft/s}}

3. We see from our equation in part 1 (v=16t+\frac{h-c}{t}) that when t=0, the denominator of our fraction will be equal to 0. Since we cannot divide by 0, the velocity remains undefined and cannot be determined.
