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,

Based on the above information, the calculation is as follows:

[tex]A = P (1 + r\div 12)^ {r\times t} \\\\= $5,000 (1 + .023\div 12)^ {12(10)}[/tex]

= $6,291.6

[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:

No, it will not change

Step-by-step explanation:

Because the size of the tank is not a factor that can be used to find the rate of change. The rate of change will continue to be 30 gallons per minute.

The average rate of change of gallons per minute is 30 gallons per minute.

No, the average rate of change of gallons per minute will not change even if the size of the tank is doubled because the size of the tank is not used to find the average rate of change.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

From the graph,

Two coordinates to find the average rate of change in gallons per minute.

(1, 30) and (3, 90).

These coordinates represent a change in the amount of water in the given unit of time.

x-coordinates is the time.

y-coordinate is the amount of water.

Now,

The average rate of change of gallons per minute:

(1, 30) = (a, b) and (3, 90) = (c, d)

= d - b / c - a

= 90 - 30 / 3 - 1

= 60 / 2

= 30

Thus

The average rate of change of gallons per minute is 30 gallons per minute.

No, the average rate of change of gallons per minute will not change even if the size of the tank is doubled because the size of the tank is not used to find the average rate of change.

Answer:

y = -4/3x - 6

Step-by-step explanation:

1. Find the slope. Since we know that a line perpendicular to another is it's opposite reciprocal, or the product of the two is equal to -1, we can find the slope. -4/3 times 3/4 is -1, so -4/3 would be the slope of this line.

2. Plug in the point and slope into the slope-point equation. The equation would be y - 2 = -4/3 * (x + 6).

3. Simplify. The simplified equation would be y = -4/3x - 6.

Answer: y = -4/3x - 6

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.

Answer:

The amount of water leaking per hour is 3/4 of the bucket volume

Step-by-step explanation:

The given parameters are;

The volume of water in the bucket = 3/10 of the bucket volume

The time duration of the leak = 2/5 hour

Therefore;

The leak rate = Volume/Time

The amount of water leaking per hour = (3/10 of the bucket volume)/(2/5 hour)

The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume/hour.

The amount of water leaking per hour is  [tex]\frac{3}{4}[/tex] of the bucket volume.

Given ;

The volume of water in the bucket =  [tex]\frac{3}{10}[/tex] of the bucket volume

The time duration of the leak =  [tex]\frac{2}{5}[/tex] hour

Therefore;

The leak rate = [tex]\frac{volume }{time}[/tex]

The amount of water leaking per hour = ( [tex]\frac{3}{10}[/tex] 0f the bucket volume)/([tex]\frac{2}{5}[/tex] hour)

                                                                =  ( [tex]\frac{3}{10} . \frac{5}{2}[/tex] ) volume per hour

The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume per hour.

Answer:

[tex]\frac{n^{2}}{2a}[/tex]

Step-by-step explanation:

Answer:

(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!
