In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds.
what was the acceleration of the cart with low fan /s2
what was the acceleration of the cart with medium fan /s2
what was the acceleration of the cart with high fan /s2

the answer is b ) square root of 5

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

the answer is 12 as i may remember

: )

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
