Victoria had $200 in her account at the end of one year. at the first of each subsequent year she deposits $15 into the account
and earns 2% interest on the new balance, compounded annually. which recursive formula represents the total amount of
money in victoria's account at the end of the nth year?
a, - 1.02( a -1 +15), aq - 215
an - 15+1.02a -1, 2, - 215
2,- 1.02(an-1 +15); a, - 200
an = 15+1.02am-11 an - 200
answer:x = 21
the formula of a volume of a square pyramid:
a - edge of base
h - height
i don't think that there's a unique answer, because it depends on the numbers you choose: for example, if you pick , then you have
but for example, if you if you pick , then you have
even if you wanted to use formula, you can at most solve one variable in terms of the other two:
to show that two measurements are nearly equivalent, we must convert one of the measurements to the other unit.
1 fl oz = 29.574 ml
v₁ =12 fl oz × (29.574ml/1 fl oz)
= 354.89 ml
v₂ = 355 ml
the difference of 0.11 ml corresponds to two drops of lemonade.
∴ v₁ ≈ v₂
