Answer:

Step-by-step explanation:

I don’t know why they bother teaching recursive formulas as the explicit is almost always used :)

For 2,9,16,23...

Recursive is a(n+1)=an+7

Explicit is an=2+7(n-1)

(or more neatly an=7n-5)

For 2,14,98,686...

Recursive is a(n+1)=7an

Explicit is an=2(7^(n-1))

(or (2/7)7^n )

Which of the following graphs represents exponential decay?

charle [14.2K]

Answer:

Step-by-step explanation:

C is the only viable answer, because it it the only one that decreases as x approaches infinity. Exponential decay decreases, hence the decay part.

Rachel bought 3 CDs that were each the same price. Including sales tax, she paid a total of $35.40. Of that total, $2.70 was tax

kotegsom [21]

Answer:

Step-by-step explanation:

Total bill - the tax = cost of 3CD's

Our total bill is $35.40, the tax is $2.70, therefore,

35.40 - 2.70 = cost of 3 CD's so

3 CD's = $32.70

Divide that by 3 to get the cost per CD:

32.7 / 3 = $ 10.90 per CD
