We see this a geometric sequcne because each term is -6 times of the previous term

an=a1(r)^(n-1)
an=nth term
a1=first term
r=common ratio
n=which term

we see that it multiplies by -6 each time
and the first term is 1

so r=-6
a1=1

an=1(-6)^(n-1)
the explicit formula is
$a_n=1(-6)^{n-1}$

and a5=1(-6)^(5-1)=1(-6)^4=1296

storchak [24]

6x^{2}+4x

Factor: 2x out of 6x^{2}

2x (3x) + 4x

Factor: 2x out of 4x

2x (3x) + 2x (2)

Factor: 2x out of 2x (3x) + 2x (2)

2x (3x + 2)

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a>1

Pavel [41]

Answer:

4(5x + 6)

Step-by-step explanation:

To start, let's expand things out, as we cannot learn anything from this form. We get 30x + 20 - 10x + 4, or 20x + 24. To find the GCD (Greatest Common Divisor), we take the terms and try to find the number (or term) that divides them. It must be a constant, because of the 24, and 4 goes into 20 and 24. So, our final answer is 4(5x + 6).

Meg found one treasure at − 3 4 foot. Which of these location are higher than − 3 4 foot? Check all that apply. Negative StartFr

Neporo4naja [7]

Answer:

$\frac{-1}{4}$ and $\frac{-5}{8}$ are the locations higher than $\frac{-3}{4}$ foot

Step-by-step explanation:

We are given that Meg found one treasure at $\frac{-3}{4}$ foot

We are supposed to find Which of these location are higher than $\frac{-3}{4}$ foot?

i) $-\frac{7}{8}$

So, this location is not higher than $\frac{-3}{4}$ foot

ii) $-\frac{1}{4}$

So, $-\frac{1}{4}>\frac{-3}{4}$

So, this location is higher than $\frac{-3}{4}$ foot

iii) - 1 foot

$-1 < \frac{-3}{4}$

So,this location is not higher than $\frac{-3}{4}$ foot

iv)-2 feet

So,this location is not higher than $\frac{-3}{4}$ foot

v) $\frac{-5}{8}$

So, this location is higher than $\frac{-3}{4}$ foot

A cross country team is made up of 65% male runners. What fraction of the team is male?

Nikitich [7]

Percentage is the same as a fraction over 100, where the number 100 represents a 'whole'.

Therefore, if 65% are male, it means if there were 100 runners in total, 65 of them would be male, so your fraction would be 65/100.

However, you can simplify this fraction as both 65 and 100 have common factors. So you keep dividing both numbers by its factors until there are no more common factors left. This will leave you with 13/20.

Therefore your final answer is 13/20.

1) Find the ending balance after these transactions: Transactions: A. Your

dem82 [27]

The ending balance after the transactions is; $59.25

<h3>How to determine ending balance</h3>

To determine the ending balance after a number of transactions;

Let money inflow and balance be represented as positive.
Let money outflow be represented as negative.

Therefore; Since starting balance is; $822.67; we have;

<em>$822.67 + $227.45 - $600.00 + $50 - $100 - $200 - $3.50 - $2.50 - $134.87.</em>

The ending balance on the account is therefore; $59.25
