Answer:
nth term is (110)^n-1
Step-by-step explanation:
This is an arithmetic sequence so the explicit equation for that is
(a of n)= a1 * (r)^n-1
the nth term is (a of n)
(a of n)= 11* (10)^n-1
(a of n) = (110)^n-1
Answer:
p(9-4+5) = 0p = indeterminate
Step-by-step explanation:
there's no explanation, it's a simple concentration
Make a proportion,
1 wall/30 minutes=x wall/5 minutes
cross mulitply,
5=30x
x=5/30=1/6
1/6 of the wall in 5 minutes
Hope this helps.
Answer:
4
Step-by-step explanation:
Q*1/5-t
Q=k/5-t
8=k/5-3
8=k/2
8x2=16
k=16
Q=16/5-t
16=16/5-t
16(5-t)=16
80-16t=16
80-16=16t
64/16=t
t=4
