NSS...I think the answer is 8000/18  =  $444.44 ⇒  "B"

P = 4864.77

r = interest rate  =  .039

n =  compoundings per year  =  2   [ twice per year ]

t = time =  2  [years] 

So we have

A  = 4864.77 [ 1 + .039/2]^(2* 2 )   = $5255.47 ⇒ "C"

Income =  Interest earned  - check fee - financial charge

1210 (.008)  -  21 (.10)  - 2.00   =  $5.58 ⇒ "B"

Plugging the values in, we attain 4000*0.035*2=$280, (B). 

OK, NSS...I'm going to let you do this one

1. Add the night deposit to the opening balance

2. Total up  the checks....subtract this from 1

3. From 2...subtract the amount transferred to savings

This will be your ending balance....I'll double-check it if you want me to...

1. $1 equals 4 quarters or 10 dimes. So, we have the conversion factor of 10/4. Thus, 10/4*354=885 dimes.

2. 1 dollar equals 4 quarters, 52 quarters equals 52/4=13 dollars.

3. $1 equals 4 quarters or 20 nickels. Therfore, a conversion factor is 20/4=5. Thus, 35*5=175 nickels.

4. 1 quarter equals 25 pennies, so 75 quarters equal 1875 pennies. 

"D"

See here, NSS....https://www.investopedia.com/financial-edge/1111/3-easy-ways-to-improve-your-credit-score.aspx

We want to solve this

-0.06 x  + 8.3   >  -0.02x + 6.6     add -0.02x to both sides...subtract 8.3 from  both sides

-0.04x  > -1.7     divide both sides by  -0.04 ..... reverse the inequality sign

x < 42.5   [  after  42 checks are written Long's bank is cheaper than Fellow's bank ]

First one  ⇒  negative rate of change

Second one ⇒ positive rate of change

Third one ⇒ negative rate of change

Last one ⇒  positive rate of change

Thank you so much!

Hey melody,

how are you. Thank you for answering my question. Also sorry about the question, I will try to not do that again. And by subtracting you get 18 right :)

See my answer here : https://web2.0calc.com/questions/geometry-help_67

"y" =  180 - 131   = 49°   = the vertical angle to y at the bottom left of the top triangle

The angle supplemental to the 142° angle = 180 - 142  = 38°

So "w"  =  180 - 49 - 38  = 93°

By the interior angle theorem, the angle at the bottom right of the top triangle = 93 - 42  = 51°

So..  "t"  will =   180 - 49 - 51   =  80°

Thinking it has to be (c) but you're the one in the class that's teaching this stuff.

i.e. \(\dfrac{10\%}{12}=0.833\%\)

Look at the following graph : https://www.desmos.com/calculator/rfebje54mw

The first two constraints just tell us that we are in the first quadrant...we can ignore them

The x/y coordinates that maximize the objective function occur at the cornrer point (12,5)

So...the max value is

C  = 7(12) + 9(5)  =  84  + 45   =  129

I only have x so far, which is 65.

Lol yeah that's true. I got it though I THINK I was right. There is no question besides what I showed.

\(180^\circ \text{ is the sum of the interior angles of a triangle}\\ x = 180-42=73 = 65\\ \text{the sum of supplementary angles is }180^\circ \\ y = 180 - 131 = 49 \\ \text{Now z is supplementary to the unlabeled angle that is }180-x-y \\ \text{thus }z = 180 - (180-x-y) = x+y \\ z = 65 + 49 = 114^\circ\)

Some of these letters are easy to find so what have you found so far ?

x (x+5) = 500 (at least)

x^2+5x-500 = 0       quadratic formula shows x = 20    plot is   20  x  25 '

20 x 25 = 500 sq ft

perimeter = 90 feet     

Hmmmm....is there a QUESTION associated with this......they are listed in the correct order....  (though SOME may consider losing 3 pounds/week as a POSITIVE thing! )
