The first one
y = 6.6 (1/2 ) ^n where n = the number of half lives
42 days/ 14 days/halflife = 3 halflives
Answer:
3 1/2 cups
Step-by-step explanation:
Let's start by figuring out how much sugar Karen needs in total.
She needs (1+1/3) cups for her original recipe. To triple that, we need (1+1/3) 3 times. We can calculate this by multiplying it by 3.
(1+1/3) * 3 = 3 + 1 = 4
Karen needs 4 cups in total. She has 1/2 cup. The difference is how much more she needs. Therefore, she needs 4 - 1/2 = 3 1/2 cups
No because when -4 is substituted in for n the answer is 37 so it is not true
Answer:
C
Step-by-step explanation:
the answer is C
( -6 , 1 )
y = -1/2x - 2
if x = -6
y = -1/2(-6) - 2
y = 3 - 2
y = 1
Plug all the point into your calculator. Not sure if you need it y=mx+b but the R for that is r= -1
