Circumference equals pi times the diameter, so you would divide by pi. (3.14159265...)
y = 2x+3 + 4 cuts the y axis when x = 0 so y = 23 + 4 = 8 + 4 = 12. Therefore, the point is (0, 12).
Multiply the number of days times 24 (hours/day) times 60 (minutes/hour) x 60 (second/minute).
51-2x = 0.25 51 * 5-2x = 0.25 5-2x = 0.05 -2x*ln(5) = ln(0.05) x = ln(0.05)/[-2*ln(5)] = 0.931
