An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.

Given the geometric sequence where a_1 = 3 and r = √2 find a_9

sesenic [268]

To find n-therm of a geometric sequence, we are going to use the formula $a_{n} =a _{1} r^{n-1}$
where:
$a_{n}$ is the term we are looking for
$a _{1}$ is the first term
$r$ is the ratio
$n$ is the position of the number in the sequence

From the question we now that $a _{1} =3$ , $r= \sqrt{2}$ , and $n=9$ . Lets replace those values into our formula to get:
$a _{9} =3( \sqrt{2} )^{9-1}$
$a_{9} =3 \sqrt{2} ^{8}$
$a_{9} =48$

We can conclude that in our geometric sequence $a_{9} =48$ ; therefore, the answer is A.

Joe works full time as a carpenter and brings home $3,000 per month. He owes a total of $1,500 in fixed expenses every month, wh

sashaice [31]

His ending balance would be $500. If you subtract $3,000 from $1,000 you get $2,000..then when you subtract $2,000 from $1,500 you get $500!!
