Step-by-step explanation:
The particle is at rest when the derivative of x(t), which is its velocity, is zero, i.e.,
![\dfrac{d}{dt}[x(t)] = \dot{x}(t) = 0](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdt%7D%5Bx%28t%29%5D%20%3D%20%5Cdot%7Bx%7D%28t%29%20%3D%200)
Since
its derivative is

Equating this to zero, we get

This is a familiar quadratic equation whose roots are




This means that the particle will be at rest at t = 3 and t= 4.
Answer:
4
Step-by-step explanation:
We convert this word equation to a number equation, then work it out.
7+4x=23 Use 'x' for the number we want to find.
4x=16 Subtract 7 on both sides.
x=4 Divide both sides by 4

Answer:
The <em><u>Money Raised</u></em> changes by adding <em><u>5</u></em> per every extra <em><u>Boxes of Chocolates Sold</u></em>. constant rate is 5
Step-by-step explanation:
What the question asks is to find whether the rate is constant or not. Since the formula y = 5x (y = <em>Money Raised</em>, k = 5, x = <em>Boxes of Chocolates Sold</em>.) works for the entire table, your answer will be this:
The <em><u>Money Raised</u></em> changes by adding <em><u>5</u></em> per every extra <em><u>Boxes of Chocolates Sold</u></em>.
Hope this helps! :D
