A particle moves along the x-axis so that at timet > 0 its position is given by X (t) = - + + 10+
t + 10+2 – 28t. Determine the acceleration of the particle at t = 4.

What value of x is in the solution set of –5x – 15 > 10 + 20x?

Three cylinders have a volume of 2836 cm^3. cylinder a has a height of 900 cm. cylinder b has a height of 225 cm. cylinder c has a height of 100 cm. find the radius of each cylinder. use 3.14 as an approximate for π

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65
