(n^2)/2a
Step-by-step explanation:
We'll take this in small steps. Don't worry and follow along if you wish :D
Where do we start? Well, first, we notice that all of the numbers/variables (on both the denominator and the numerator) are multiplied by each other. If this case had addition or subtraction in the fraction, the explanation would have differed.
Let's take on a simpler example to show you what I mean. Here's a relatively simpler equation with no pesky variables:
(1 + 3)/4
This equation has to be broken down like this:
1/4 + 3/4
And although we could just do (1 + 3) quickly and divide by 4, consider it if we replace them with numbers instead, or variables in other words:
(x + y)/x
Then, it would work the same way as the previous example:
x/x + y/x
And that would further simplify to (1 + y/x).
But, we're lucky! Because there is no addition or subtraction, we won't have to divide all the numbers that are in the numerator with the number(s) in the denominator. Consider this:
(3*4)/4
We only need to divide 4 by the denominator (which is also four, in this case) and not both 3 and 4 like how we would solve if it had addition or subtraction.
First step! Let's take all of the variables out of this nasty equation we have on our hands to make it simpler:
(9an^3)/(18a^2n)
We would be left with...
9/18
And then we would reduce to leave 1/2. Notice that if we add all the variables back, we would have:
(1an^3)/(2a^2n)
Or (an^3)/(2a^2n)
If we write it out, we'll find this equation a tad bit easier with the large numbers dealt with (although I will admit, it doesn't look that great on the screen—lol)!
Back to business. Here, we need to simplify the variables. Given, we have to remember that variables are just your every-day number (but unknown). Because of that, we get to divide them very much like how we would with regular numbers. Rope in some of our previous lesson about not having to divide all the numbers on the numerator from the denominator from the beginning, too!
(an^3)/(2a^2n)
You can cancel out the variable a^ in this equation. That would leave you with:
(n^3)/(2an)
Try to simplify the rest on your own and use my work to check your answers! if you can't, then no worries. Follow along with me :D
We can also reduce using n. That will leave:
(n^2)/2a
And then you're done! I would recommend more questions like these (if you aren't already doing them) because you'll be using simplifying techniques similar to this equation in the future.
Good luck and keep studying!

Annie needs $30 to buy a coat she has saved $12 and plans to work as a baby siter to earn $6 per hour which inequality shows the minimum number of hours, n, that annie should work as a babysitter to earn enough to buy a coat?
a 12 + 6n ≤ 30, so n ≤ 3
b 12 + 6n ≥ 30, so n ≤ 3
c 6n ≥30 + 12, so n ≥ 7
d 6n ≤30 + 12, so n ≤ 7
Answer:
The answer would be B. 12 + 6n is greater than or equal to 30, so n is less than or equal to 3.
explanation:
I'm bad with explaining things, but I'll try my best to explain why this is the right answer.
12 + 6n ≥ 30, so n ≤ 3
let's start with the 12 at the beginning of the inequality, Annie already has $12, so the 12 in the inequality shows the amount of money she already has being added to the $6 per hour of babysitting she needs to do (n).
Now for the + 6n, the plus is there to show that the $12 Annie already has is being added to the 6n. The 6n then represents the $6 Annie makes each hour and the n represents how many hours she needs to babysit in order to get $30. The 6 is being multiplied by the amount of hours she needs to babysit to show how much money Annie would make. Then you add on the $12 she already has.
Annie then needs at least $30, but if she makes more than $30 then she will simply have more money than needed, therefore you use the greater than or equal to sign to show that she can have more money than just $30 after working.
I hope this helps, and sorry if my explanation is hard to understand lol.
which equation could represent each graphed polynomial function
PLEASE HELP FAST!!!
Answer:
y = x⁴- 5x² + 4
y = x(x + 3)(x - 2)
Step-by-step explanation:
1). y = x⁴- 5x² + 4
= x⁴- 4x² - x² + 4
= x²(x² - 4) - 1(x²- 4)
y = (x² - 1)(x² - 4)
y = (x - 1)(x + 1)(x - 2)(x + 2)
Therefore, zeros of this polynomial are,
x = -2, -1, 1, 2
From the given graphs, first graph has the zeros (x-intercepts) as x = -2, -1, 1, 2.
So the graph (1) represents the polynomial → y = x⁴- 5x² + 4
2). Second graph shows the x-intercepts at x = -3, 0, 2
Since, y = x(x + 3)(x - 2) is the polynomial with x intercepts at x = -3, 0, 2
Therefore, y = x(x + 3)(x - 2) represents the second graph.

Which relation is also a function?
Bianca buys 4 band shirts and 3 pairs of pants for $159, and Gianna buys 3 of the same shirts and 2 of the same pairs of pants for $113.
How much does it cost to buy 5 band shirts and 5 pairs of pants?
Answer:
$150
Step-by-step explanation:
ok, so first you want to create your equations. let s=shirts, and p=pants. 4s+3p=159, and 3s+2p=113. next you want to get one variable in each equation to be the same. I multiplied the first by 2 and the second by 3 to make the ps the same. now we subtract our equations. (9s+6p=339) - (8s+6p=318) this gives you s=21. Now we put that in to solve for p, it doesnt matter which of the 4 equations. 4(8)+3p=159 = 3p=127 = p=42 1/3. now we just multiply them to find the cost of 5 of each. which is the answer above.

Gregory may choose between two accounts in which to invest $5000. Account A offers 2.3% annual interest compounded monthly. Account B offers continuous compound interest. Greg plans to leave his investment untouched (no further deposits and no withdrawals) for 10 years.
need help calculating account b's balance
Answer:
see below
Step-by-step explanation:
principal = $5,000
interest rate = 2.3%
account A: compound monthly for 10 years
account B: compound continuously for 10 years
account A: compound monthly for 10 years
A = P (1 + r/12)^ r*t
= $5,000 (1 + .023/12)^ 12(10)
= $6,291.6
account B: compound continuously for 10 years
FVn = PV * e^r*t
= $5,000 * e ⁽⁰ ⁰²³ˣ¹⁰⁾
= $6,293
Gregory may chose account B. (but the difference is only $1.40)
Gregory may choose account B.
Given that,
Principal = $5,000 .The interest rate = 2.3% .Account A: compound monthly for 10 years .Account B: compound continuously for 10 years
Based on the above information, the calculation is as follows:
For Account A[tex]A = P (1 + r\div 12)^ {r\times t} \\\\= $5,000 (1 + .023\div 12)^ {12(10)}[/tex]
= $6,291.6
For account B
[tex]FVn = PV \times e^{r\times t}\\\\ = $5,000 \times e^ {0.023\times 10}[/tex]
= $6,293
Therefore we can conclude that Gregory may choose account B.

Answer:

(-6,+ 00)A squirrel runs across a road in 3 seconds. The road was more than 34 feet wide.
_______________________________________________________
Which inequality can be used to determine the squirrel’s speed?
_____
What is the solution to the inequality? Round to the nearest tenth, if necessary.
_____
How can you interpret the solution?
_____
_______________________________________________________
A) 3r > 34,
3r 34
r/3 11.3
r 10.2
C) the squirrel ran at least 11.3 feet per second
the squirrel ran faster than 11.3 feet per second
the squirrel ran no faster than 102 feet per second
the squirrel ran slower than 102 feet per second
_______________________________________________________
Answer:
✔ 3r > 34
✔ r > 11.3
✔ The squirrel ran faster than 11.3 feet per second.
Step-by-step explanation:
1. The Squirrel's speed is 3r > 34
2. The solution of the inequality is r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
A squirrel runs across a road in 3 seconds.
The road was more than 34 feet wide.
1. The Squirrel's speed is
3r > 34
2. The solution of the inequality is
r > 34/3
r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.
