My apologies.

It litereally says :

Find the nominal annual rate of interest. Then lists

(c) if the effective annual rate of interest is 7.75% and compounding is done monthly

(d) that is equvilant to 6% compounded quarterly

Not too sure if we are making any progress but thats literally what it says lol.

Sorry for confusion

OK. That is much clearer. In (c) the effective annual rate is 7.75%=7.49% nominal rate compounded MONTHLY.

(d) Is still NOT clear what they want. However, 6% comp. quarterly=6.14% effective annual rate=5.97% comp. monthly=5.96% comp. daily=6.05% comp. semi-annually........etc.

it only equals one if you round it.

There is no solution to this......

6x + 1   = 6x - 8       subtract 6x from both sides

1 =  - 8        but this is impossible....!!!!....so.....no solution exists  !!!

What model????

tan(15°)  = 300 / d     rearrange as :

d = 300/ tan(15°)  = about 1119.6 ft

what is the formula for total surface area. OF WHAT? Sphere, Solid rectangle, Cube, Cylinder.....?

−14(d+1)<2        divide both sides by -14    and reverse the inequality sign

d + 1  > -2/14     subtract 1 from both sides

d > -2/14 -  1

d > -2/14 - 14/14

d  > -16/14  = -8/7

See my answer to your question # 12

You must understand what the word "nominal" means. It means "in name only". But you have to specify the compounding period. Example: 8% is effective annual rate. What is the nominal rate compounded, daily, monthly, quarterly, semi-annually.........etc.

Here is a method to convert any repeating decimal to a fraction :

1. Write the non-repeating part of the decimal and append the repeating part and drop the decimal.......for convenience......we'll  call this 99...[there isn't any non-repeating part, here]....it won't make any difference how many more 9's we append, as you shall see

2. Subtract the non-repeating part  from this........in this case, there is no non-repeating part.......so we still have 99

3.  Write the same number of 9's as we have repeating digits and append the same number of 0's as the non-repeating digits........we only have 2 repeating digits  and no non- repeating ones..........so, this ends up being 99

Put the result in 2  over  the result of 3     and we have:

99 / 99   = 1

To show that this works.....consider  .127272727.......etc.      .....we would have   [ 127 - 1] / [ 990]  = ,127272727........

A $4000 debt due in four years was paid with $3885.35 cash. If money is worth 7% compounded monthly, how many months before the due date was the debt paid?

Here, you have to find the PV of $4,000 =$3,025.60

Then, you find the number of months this PV grows to $3,885..35

If you do right, you will see that it takes 43 months. Therefore,

48 - 43=5 months earlier, that the loan was paid off.

Find the nominal rate of interest  (c) if the effective annual rate of interest is 7.75%

Find the nominal rate of interest (d) that is equvilant to 6% compounded quarterly

I don't understand the question?     

(a) At which $1000 will grow to $1800 in four years compounded monthly;=14.79% comp. monthly

(b) at which money will double in seven years if compounded quarterly=10.03% comp. quarterly

(c) if the effective annual rate of interest is 7.75%

(d) that is equvilant to 6% compounded quarterly

Don't know what you want in part c and d. Explain it clearly.

The selling price before the tax  =   90*1.4 =  $126

So....the sales tax  = $ [134.82 - 126]  = $8.82

The circumference of a circle is called pi which is 3.14 but pi is an weird infinite number and when you seach it you could find the longest or long aproximate and how to solve it but not searching it up but asking it here was not a good choice to do first. Search the web then ask. Its the best way.

sin2A = tanA - Cos2A

Here's a graph of the intersections of both sides.......https://www.desmos.com/calculator/05szgkl0av

At   [45° +/- 180n] °...where n is an integer.....sinA = cosA   so the answer is 0

At [135° +/- 180n] °...where n is an integer.....cosA = -sinA........and sinA  = sqrt(2)  / 2   ......so.............sinA - cosA   =  sinA + sinA = sqrt(2)/2  + sqrt(2)/2 =   sqrt(2)

I know that there is a proof, but why does 0.9 repeating equal 1? Since they are labeled differently, shouldn't they be different numbers?

Here's what you can do.......https://www.desmos.com/calculator/ycmw7rt9km

The red graph is the original.....the gold is the shifted graph with only one x intercept.....

5/7 x 4/15 = 4/21

4/21 x 28/9 = 16/27 or 0.59259259

16/27 is your answer

Add them ALL up and divide the result by 5.
