Subtract the 2x and divide by -4. y=1/2x-2 or y=x/2-2
Answer:
t=5.18 minute
Step-by-step explanation:
Using Newton's law of cooling

T is temperature of a cup of coffee at any time t
, is the temperature of the surrounding and k is a constant of proportionality in this negative because temperature is decreasing.


To find constant knowing the time and the temperature the first step of the change of energy in cup of coffee

Now using the constant of decreasing can find the time to be a 145 temperature the cup of coffee


Answer: 37.68 square inches of paper
Step-by-step explanation:
Hi to answer this question we have to calculate the side area (since the label doesn't cover the top and bottom area)
First, we have to find the circumference.
Circumference (C) = 2 π r
Since:
Diameter = 2 radius
3 = 2r
3/2 =r
r =1.5 inches
Back with the circumference formula
Replacing with the values given:
C = 2 (3.14) 1.5
C= 9.42
Side area = C x heigth = 9.42 x 4 = 37.68 square inches
