The answer is #2. 3/2. The dot rises 3 lines and moves to the right 2 lines.
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
That implies a simple multiplication, with a couple considerations:
17.5 percent = 17.5% = 17.5/100 = 175/1000
so we multiply both quantities:
17.5% of 2400
= (17.5%)(2400)
= (175/1000)<span>(2400)
</span>= 175*2400/1000
= 420
Answer:
I think the answer will be x⩽4
