Answer:

Assuming that all three sides are 9 inches then the answer should 729.

Step-by-step explanation:

Just multiply 9*9*9. The formula to get volume is (length)*(width)*(height).

the amusement park charges a fee of $7.50 and $0.75 for every ride. the carnival charges a fee of $10.00 and$0.50 per ride. when

andrew11 [14]

A equation to represent this situation is:

$0.75x+7.50=0.50x+10.00$

Now we have to find x.

Step 1: Subtract 0.5x from both sides.

<span><span><span><span>0.75x</span>+7.5</span>−<span>0.5x</span></span>=<span><span><span>0.5x</span>+10</span>−<span>0.5x</span></span></span><span><span><span>0.25x</span>+7.5</span>=10

</span>Step 2: Subtract 7.5 from both sides.

0.25x+7.5−7.5=10−7.50.25x=2.5

Step 3: Divide both sides by 0.25.

<span><span><span>0.25x/</span>0.25</span>=<span>2.5/<span>0.25

Given a geometric sequence in the table below, create the explicit formula and list any restrictions to the domain.

Makovka662 [10]

Given:

The geometric sequence is:

$n$ $a_n$

1 -4

2 20

3 -100

To find:

The explicit formula and list any restrictions to the domain.

Solution:

The explicit formula of a geometric sequence is:

$a_n=ar^{n-1}$ ...(i)

Where, a is the first term, r is the common ratio and $n\geq 1$ .

In the given sequence the first term is -4 and the second term is 20, so the common ratio is:

$r=\dfrac{a_2}{a_1}$

$r=\dfrac{20}{-4}$

$r=-5$

Putting $a=-4,r=-5$ in (i), we get

$a_n=-4(-5)^{n-1}$ where $n\geq 1$

Therefore, the correct option is B.
