Please help
Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 54 km/h. After four hours, the velocity of the car is 58 km/h.

Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. (5 points)

Part B: How can you graph the equation obtained in Part A for the first six hours? (5 points)

dan815 · Answer

how much did the velocity change by and in what time

anonymous · Answer

0.2

dan815 · Answer

try again

dan815 · Answer

look at the difference in the velocities you are given

anonymous · Answer

I have 54 and 58

dan815 · Answer

and how much time elapsed while this change was taking place

dan815 · Answer

58 km/hr - 54km/hr = 4km/hr
this change took between the t=2hrs and t=4hrs
so in 2 hours your speed changed 4 km/r

dan815 · Answer

4 km/hr

dan815 · Answer

so avg acceleration=change in velocity/change in time = ?

anonymous · Answer

4?

dan815 · Answer

no

dan815 · Answer

what is your change in velocity?

dan815 · Answer

|dw:1392701206098:dw|

dan815 · Answer

acceleration is the slope of this line

@dan815 Will you help me with this question? I made a function already but Idk how to put it into standard form

elise_a18 · Answer

f(x)= 52(1.93)^2
