The two roots of this functions are the exact roots and one is an imaginary root. The -2 is the root of a negative number -16 because if you compute the -2 on its 3rd power you come up -16, the 2 is the root of 16 and the 4+i contains a imaginary number that is why it is an imaginary root

Answer:
Speed
Explanation:
Aliyah must have been trying to find her speed.
The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,
speed =
with a unit of m/s.
<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>
