Answer:

The interest charged is $7.49.

After 29 days, Travis paid a total of $607.49

Step-by-step explanation:

Travis obtained a cash advance for $600.

The interest rate is 0.04305% per day.

The simple interest rate formula is given by:

I=Prt

Where <em>I</em> is the interest, <em>P</em> is the initial amount, <em>r</em> is the rate, and <em>t</em> is the time (in this case in days).

Our initial amount <em>P</em> is $600.

Our interest rate <em>r</em> is 0.04305% or (moving the decimal two places to the left) 0.0004305.

Since Travis repaid the loan after 29 days, our <em>t</em> is 29.

Hence, our interest is:

I=600(0.0004305)(29)=7.4907

So, the interest charged is about $7.49.

So, after 29 days, Travis paid a total of the original $600 plus an interest of $7.49 for a total of $607.49

Graph the six terms of a finite series where a1 = −3 and r = 1.5.
s344n2d4d5 [400]
We are given the first term and the common ratio, this means they belong to a geometric series.

For the given series:

a_{1}=-3 \\ &#10;r=1.5

Each term of the geometric series is obtained by multiplying the previous term by common ratio.

So the next terms will be:

-4.5, -6.75, -10.125, -15.1875, -22.78125

The general formula for the G.P would be:

a_{n}=-3(1.5)^{n-1}

On plotting the series, the result will be like this:
