Answer:
The answer is "She is right since the center in the middle of the sphere is a fixed point".
Step-by-step explanation:
- We have a certain habit of the rules of equations in maths for points, coordinates, sections, edges, etc. Generally, developers mark points, researchers much more mark with the very first letter of an entity which we signify.
- This also shows divisions of a circle and a sphere as radius through a letter, r as radius, has high and usually as capital letters. If they denote radius, it should be put in the center or over the section we denote with such a small letter.
- They just need to put the letter near the point they are going to point out for marks, that's why it is correct.
In accordance with the function <em>velocity</em>, the car will have a complete stop after 6 seconds.
<h3>When does the car stop?</h3>
Herein we have a function of the velocity of a car (v), in feet per second, in terms of time (t), in seconds. The car stops for t > 0 and v = 0, then we have the following expression:
0.5 · t² - 10.5 · t + 45 = 0
t² - 21 · t + 90 = 0
By the <em>quadratic</em> formula we get the following two roots: t₁ = 15, t₂ = 6. The <em>stopping</em> time is the <em>least</em> root of the <em>quadratic</em> equation, that is, the car will have a complete stop after 6 seconds.
