Can someone tell me if i got these three derivative math problems right?

1.  2x

2. v(t) =2

3.  24mph

Step-by-step explanation:

1.  W(t) = x^2 -3

 dw/dt  = 2x dx/dt

2. v(t) =2

Take the derivative to get the acceleration

dv/dt = 0

The choice you picked has 0 velocity so it is not in motion

3. To find the velocity

x(7) - x(5)

7-5

2(7)^2 -2(5)^2

7-5

2*49 - 2*25

2

98-50

2

48/2

24 mph

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
