Answer:
10·2^-8 grams
Step-by-step explanation:
The each day, the initial amount for that day is multiplied by 1/2. After 8 days, the initial amount has been multiplied by (1/2)^8, where the exponent of 8 signifies that (1/2) is a factor 8 times in the product.
After n days, the quantity remaining is ...
q(n) = 10·(1/2)^n = 10·2^(-n)
after 8 days the remaining amount is ...
q(8) = 10·2^-8 . . . grams
If this is a perfect square trinomial, you want to look at your constant--36. the square root of 36 is 6, so your factors would be:
(x + 6)(x + 6) ... foil this, and see what your middle value is.
x² + 12x + 36 is your result. 12 is your middle term.
Answer:
A and B
Step-by-step explanation:
Let's convert 5 feet into inches and yards. We will use the conversions:
1 ft = 12 in
1 yd = 3 ft
So, 5 feet = 5 * 12 = 60 inches. Looking at the answer choices, A says 56 inches, which is less than 60, so that can work.
5 feet = 3 feet + 2 feet = 1 yd + 2 ft. Looking at the answer choices, B works because it says 1 yd, which is clearly less than 1 yd + 2 ft. However, C doesn't work because 1 yd 2 ft is equal to 5 ft.
Thus, the answers are A and B. (Note that as you didn't provide choice D, I will assume it is not an answer)
Hope this helps!
