Answer:
They invested total $2730 over the past two years.
Step-by-step explanation:
Consider the provided information.
Dan and Paula regularly invested $25/week in a mutual fund account.
There are 52 weeks in a year.
Total money they invested in a mutual fund in first year.
$25×52 = $1300
They increased their weekly investment by 10 percent.
First find the 10% or 25.
That means they invest $25+$2.5 = $27.5
They invest $27.5/week in next year.
Total money they invested in a mutual fund in second year.
$27.5×52 = $1430
Hence the total money they invested in the account over the past two year is:
$1300+$1430=$2730
Hence, they invested total $2730 over the past two years.
Answer:
Explicit formula is .
Recursive formula is
Step-by-step explanation:
Step 1
In this step we first find the explicit formula for the height of the ball.To find the explicit formula we use the fact that the bounces form a geometric sequence. A geometric sequence has the general formula , In this case the first term
, the common ratio
since the ball bounces back to 0.85 of it's previous height.
We can write the explicit formula as,
Step 2
In this step we find the recursive formula for the height of the ball after each bounce. Since the ball bounces to 0.85 percent of it's previous height, we know that to get the next term in the sequence, we have to multiply the previous term by the common ratio. The general fomula for a geometric sequene is
With the parameters given in this problem, we write the general term of the sequence as ,
