use the numbers 1,3,4,6 exactly once with any basic math operation(multiplication,division,addition and subtraction) to total 24

drek231 [11]

Step-by-step explanation:

It is 4*6! We have to play with these numbers (1,3, and 4) to create 4, or we have to play with these numbers (1,3, and 6) to create 6.

If you divide 6 by 1/4, you will get 24.

If you divide 4 by 1/6, you will get 24.

How to create 1/4 from 1,3, and 4?

How to create 1/6 from 1,3, and 6?

Creating 1/4 from 1,3, and 4 is possible by doing this: 1–3/4, it is =1/4!

So, the answer is 6/[1–3/4]=24.

Question 8: The equation of motion of a particle is

lawyer [7]

Answer:

D) $22\:\text{m/s}^2$

Step-by-step explanation:

Acceleration is the derivative of velocity, which is the derivative of position, so we must differentiate the function twice:

Position of Particle: $s(t)=t^3-4t^2+2t+8$

Velocity of Particle: $v(t)=3t^2-8t+2$

Acceleration of Particle: $a(t)=6t-8$

After $t=5$ seconds, the acceleration of the particle is $a(5)=6(5)-8=30-8=22\:\text{m/s}^2$
