Answer:
Pull together any pass homework assignments and do practice problems on the questions you missed to gain a better understanding of why you missed them. That way you do not make that same mistake again.
Step-by-step explanation:
How much time do Uu have?
Explicit rule:
a(n)=(2/5)(5^(n-1))
For a recursive rule, we need to express a(n) in terms of a(n-1), which we can obtain from the explicit rule
a(n)=(2/5)(5^(n-1))
substitute n-1 for n above
a(n-1)=(2/5)(5^((n-1)-1))
=(2/5)(5^n-2)
Divide:
a(n)/a(n-1)=(2/5)(5^(n-1)) / ((2/5)(5^(n-2)))
=1/5^(-1)
=5
Therefore, multiplying both sides by a(n-1)
a(n)=5 a(n-1)
a(1)=(2/5)(5^(1-1))=2/5
So the recursive rule is
a(1)=2/5, a(n)=5 a(n-1)
Answer:
the mango cost 1.75$ each and the peach 0.75$
Step-by-step explanation:
M= mango
P=peach
we know that Hudson spend 16$ buying 7 mangos and 5 peaches. So we can write the equation
(1) 16=7M+5P---> (2)P=(16-7M)/5
and we know that Austin spend 14.50 buying 4 mangos and 10 peaches.
we write the equation
(3)14.50=4M+10P
and we replace the P with the equation (2)
14.5=4M+10*(16-7M)/5
14.5=4M+2*(16-7M)
14.5-32=4M-14M
M=1,75$
and now we replace M in eq. (2)P=(16-7*1.75)/5=0.75$
