Each month, 8 sunflower plants are removed. Part A: Write functions to represent the number of marigold plants and the number of sunflower plants in the back yard throughout the months. (4 points) Part B: How many marigold plants are in the back yard after 3 months? How many sunflower plants are in the back yard after the same number of months? (2 points) Part C: After approximately how many months is the number of marigold plants and the number of sunflower plants the same? Justify your answer mathematically. (4 points)

If a quantity A is decreased by 15%, it means that what is left is 85% of it. 85%A= Part A. Consider the 150 marigolds. After the first month, 0.85*150 are leftAfter the second month, 0.85*0.85*150=After the third month, 0.85*0.85*0.85*150 = ..so After n months, marigolds are left. in functional notation: is …

(7X10^-21)/(7.6X10^-22) is equal to: (7/7.6)(10^-21/10^-22) Rule for division of similar bases with exponents… (a^b)/(a^c)=a^(b-c) In this case we have (10^-21)/(10^-22)=10^(-21–22)=10^1 And 7/7.6≈0.921, and we only had two significant figures so 0.92 works 0.92X10^1 9.2 So the half life of helium-9 is about 9.2 times greater than the half life of …

(Astronomers note that the true orbital period of the moon, is 27.3 Earth days. Interestingly, this would mean that there are approximately 13 months in a year. Use the 27.3 days/month for T – the time required for one revolution in your calculation.)

This sounds pretty easy, in fact. The orbital motion can be assumed to be circular and with constant speed. Then, the period is the time to do one revolution. The distance is the length of a revolution. That is 2*pi*R, where R is the distance between the Moon and the …
