Answer:
So it would takes approximately 6.9 hours to reach 32 F.
Step-by-step explanation:
For this case we have the following differential equationÑ
We can reorder the expression like this:
We can use the substitution and so then we have:
IF we integrate both sides we got:
If we apply exponential in both sides we got:
And if we replace w = u-T we got:
We can also express the solution in the following terms:
For this case we know that since w ehave a cooloing, , we have this model:
And if we want that the temperature would be 32F we can solve for t like this:
If we apply natural logs on both sides we got:
So it would takes approximately 6.9 hours to reach 32 F.

Answer:
$2800
Step-by-step explanation:
First divide $4800 by 3 which will give you $1600 which is the price for 2 cars and 1 truck.
=
Next, subtract the $1600, which is the price of 2 cars and 1 truck from $4600, which is the price of 8 cars and 1 truck giving you the price of 6 cars.
$4600 - $1600 = $3000
Now divide the $3000, the price of six cars, by three to get the price of 2 cars.
Lastly, multiply the $1000 by 2 to get the price of 4 cars. Then subtract this $2000, the price of 4 cars from the $4800, the price of 6 cars and three trucks to give you the price of 2 cars and 3 trucks.
$4800 - $1000 = $2800
