Need with this one it kind of hard

we have

where

v(t) is the speed of the car in mph

t is the time in seconds

the domain of the function is the interval ------> (given problem)

so

V(5) -----> that means the speed of the car for the time equal to seconds

Find the speed of the car for

substitute the value of t in the formula above

therefore

the answer is the option D

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
