A student collected data about the distance a car travels over time. Which type of graph should he use to show the data?

A. Bar graph
B. Scatterplot
C. Circle graph
D. Histogram

Therefore the correct answer is B.  Scatterplot

Explanation:

This is an exercise in kinematics, in a measurement of distance against time, the process is described by the expression

          x = vo t + ½ a t2

where vo is the initial velocity. At the acceleration of the body, x the displacement and t the time.

Depending on the type of movement, a can be zero or different from zero.

In general, all these data are graphed in a DISPERSION graph where the distance is on the abscissa axis and the ordinate axis is time.

Therefore the correct answer is B

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

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 .
