Answer: $0.42
Step-by-step explanation:
The rate at which the average cost of 1 gallon of gasoline is increasing is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the cost after t years.
t represents the number of years.
b represents the initial cost.
r represents rate of growth.
From the information given,
b = $0.31
r = 3% = 3/100 = 0.03
t = 1972 - 1962 = 10 years
Therefore,
y = 0.31(1 + 0.03)^10
y = 0.31(1.03)^10
y = $0.42
For three hours is he will take up 5.25gallons.
she will be left with 4.75 gallons
Answer:
is A
r<11

I HOPE THIS HELPS
Remember that the y-intercept is obtained when the value of x is set to zero. This means that the y-intercept is the value of the height without sunlight yet. This also refers to the original height of the plant. This gives:
y = 4 + 2(0) = 4
So, the original height of the plant is 4 mm.
The formula also indicates that when sunlight is present, a height of 2mm is increased every hour of sunlight exposure.
