Cassie is travelling 675 miles today to visit her brother and his family. so far, she has stopped for gas three times. at the first stop, 7.1 gallons of gas and paid $23.79. at her second stop, she put in 5.8 of gas and paid $19.08. and, at her third stop, she put in 6.6 gallons and paid $20.39, the second part
if the gas station that cassie stopped, at last, lowers their price 6%, what will be their new price per gallon?

The last gas station she stopped at she got 6.6 gallons and paid $20.39

If they lower the price by 6%, that means she would pay 94% of the original amount ( 100% - 6% = 94%)

Multiply the amount she paid by 94%:

20.39 x 0.94 = 19.17

She would pay $19.17 total.

Now divide that by the number of gallons bought:

19.17 / 6.6 = $2.90 per gallon ( Rounded to the nearest cent).

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
