Answer:
4
Step-by-step explanation:
Number 1 is A, number 2 is B number three is D
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.

The measure of angle AED is one-half the sum of the intercepted arcs. The intercepted arcs measure 38 and 146. The sum of those is 184. Half of 184 is 92.
Answer:
Yes they can be the sides of the triangle
2 + 4 > 5
2 + 5 > 4
5 + 4 > 2
Thus the sum of two sides is greater than the third side and thus triangle with these sides are possible.
