Amounttotal=amount per day times number of days
200=17.1 times d
divide both sides by 17.1
11.695=d
about 12 days
Answer:
x = 5
Step-by-step explanation:
3 = x/ 3 + 4
This is same as
3/1 = x/ 3 + 4
Then cross multiply
1(x + 4) = 3× 3
x + 4 = 9
x = 9 - 4
x = 5
Y=(1/5)^x would be the only equation demonstrating decay of these
Step-by-step explanation:
we see the common difference is
a2-a1 = 11x + 9 - 4x - 5 = 7x + 4
an = an-1 + (7x+4) = a1 + (n-1)×(7x+4)
for a7 we have then
a7 = 4x + 5 + 6×(7x +4) = 4x + 5 + 42x + 24 = 46x + 29
