Answer:
The weight of the block of ice after 1 day is of 4.81 pounds.
Step-by-step explanation:
Equation for exponential decay:
The equation that models an amount after t hours, subject to exponential decay, is given by:

In which A(0) is the initial amount and r is the decay rate, as a decimal.
A 10-pound block of ice melts at a rate of 3% per hour.
This means that 
So



Find the weight of the block of ice after 1 day.
One day has 24 hours, so this is A(24).

The weight of the block of ice after 1 day is of 4.81 pounds.
Step 1 , switch sides - 29-3b<10
step 2 , subtract 29 from both sides - -3b< -19
step 3 , multiply both sides by -1 - 3b > 19
step 4 (answer) - divide by 3 = 19/3
Answer:
Step-by-step explanation:
They're asking for the initial fuel, which is how much it had when the distance was 0. so 500, your y-intercept
