If y=2cos(x/2) then d^2y/dx^2 =

1 answer:

5 0

We first need dy/dx.

dy/dx = -2sin(x/2)(1/2)

dy/dx = -sin(x/2)

We now find d^2y/dx^2.

d^2y/dx^2 = -cos(x/2)(1/2)

d^2y/dx^2 = -(1/2)cos(x/2)

24 is 4/5% of what number

docker41 [41]

Answer:

The number is 3000

Step-by-step explanation:

Is means equals

24 = 4/5 % *n

Lets change the percent to a decimal. To change percent, we move the decimal to places to the left.

4/5= .8

4/5 % = .8% = .008

24 = .008 *n

Divide each side by .008

24/.008 = .008n/.008

3000 = n
