A vehicle has travelled 90 miles at 40mph

Mathematics
1 answer:
kari74 [83]3 years ago
4 0

First let us calculate for the total time of the travel using the formula:

time = distance / velocity

time = 90 miles / 40 mph

time = 2.25 hours

 

Next, we calculate for the total gallons of fuel that is theoretically required:

theoretical amount needed = 90 miles / 24 mpg

theoretical amount needed = 3.75 gallons

 

The difference of the actual and theoretical amount is the amount which leaked:

amount leaked = 8 gallons – 3.75 gallons

amount leaked = 4.25 gallons

 

Therefore the amount of gallons leaked per hour is:

amount leaked per hour = 4.25 gallons / 2.25 hours

<span>amount leaked per hour = 1.89 gallons / hr</span>

Writing an Equa
kakasveta [241]

Answer:

Step-by-step explanation:

(3,1) lies below the vertex, so the parabola opens downwards.

Equation for a down-opening parabola with vertex (2,3):

y = a(x-2)² + 3, a<0

Plug in (3,1) and solve for a:

1 = a1² + 3

a  = -2

y = -2(x-2)² + 3

-4-8= -12

8-2=6

12+6=18

-12b+6c+18

Greatest common factor = 6

-12/6=-2

6/6=1

18/6=3

D 6(-2b+1c+3)

-12(2)+6(-3)+18

-24+(-18)+18
