V=u+at
u=2 a= -5 t=1/2
work out the value of v.

(-1)/2

Step-by-step explanation:

Evaluate u + a t where u = 2, a = -5 and t = 1/2:

u + a t = 2 - 5/2

Put 2 - 5/2 over the common denominator 2. 2 - 5/2 = (2×2)/2 - 5/2:

(2×2)/2 - 5/2

2×2 = 4:

4/2 - 5/2

4/2 - 5/2 = (4 - 5)/2:

(4 - 5)/2

4 - 5 = -1:

 (-1)/2

step-by-step explanation:

it's the only multiple of both and the least

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
