Which graph below would match the situation described? a car travelling at 23 mi/h accelerates to 45 mi/h in 5 seconds. it maintains that speed for the next 5 seconds, and then slows to a stop during the next 5 seconds.

The graph shows that a car travelling at 23 mi/h accelerates to 45 mi/h in 5 seconds. It maintains that speed for the next 5 seconds, and then slows to a stop during the next 5 seconds is given by option C).

Given :

The following steps can be used in order to determine the correct graph that represents the giove situation:

Step 1 - The kinematic equation for the velocity is given by:

v = u + at   --- (1)

Step 2 - According to the given data, the initial velocity is 23 mi/hr, the final velocity is 45 mi/hr and the time to accelerate is 5 seconds.

Step 3 - Substitute the known terms in equation (1).

45 = 23 + 5a

22 = 5a

a = 4.4

Step 4 - The final velocity is zero because at the end of 15 seconds.

Therefore, the correct graph that shows the given situation is option C).

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
