Step-by-step explanation:

» At point of intersection:

» Point of intersection is (1, 2)
• General equation of a line:

- m is slope
- c is y-intercept
» Consider point (1, 2);

Equation:

The third one (the one with 9 sides)
<span> the total distance around the pie is the circumference of the pie, assuming that the pie is a perfect circle then the formula for the circumference of a circle is:
c = piD
where pi is equal to 3.1416
D is the diameter of pie or circle
substitute the given values
C = (3.1416) ( 20 ft
c = 62.832 ft

Answer:
Answer is -5°C.
Step-by-step explanation:
Initial temperature = 3°C
First decrease in temperature = 5°C
Second decrease in temperature = 3°C
Balloon ascend = 900 ft
Total change in temperature = 3-5-3 = -5
Thus final temperature = -5°C
