Answer:
According to the passage, we have the next equation:

where "K" is a proportional constant
Leaving at the end with the next equation:

Integrating the equation, we have:

where "C" is a constant
Then, we have the 2 conditions for the problem:
1) t=0 → r=10
Replacing in the equation, we have C = 10
2) t=5 → r=8
Replacing in the equation, we have K = -0.4
Finally, the time which the snowball will be completely melted will be when r = 0. So replacing in the equation

t = 25 minutes
Answer:
24 times.
Step-by-step explanation:
288/12 = 24. (Long division)
Answer:
(4, 0)
Step-by-step explanation:
The circumference of a circle is
where <em>r</em> is the radius.
In this case,
. Divide both sides of the equation by
to get

The center of the circle is on the <em>x</em>-axis, so the intercepts are 5 units to the left of the center and 5 units to the right of the center. The two intercepts are (-1-5, 0) and (-1+5, 0). The point that is on the positive <em>x</em>-axis is (4, 0).

Answer:
a
Step-by-step explanation:
it is
Answer: B is the correct answer
Step-by-step explanation:
If you do the math for each question to get a price a leaves you with 725 and b leaves you with 720 and c leaves you with 760 while d leaves you paying 800 so the lowest amount would be B.
