Thank you I was so confused

Just use the calculator to work out each side of the equality.

Let n be the number of cheaper calculators. Then

n*2.95 + 40*8.20 = 387

n*2.95 = 387 - 40*8.20

n = (387 - 40*8.20)/2.95

n = 20

It says 0

1/40C6

3838380 = 3.83838e6

1/3838383

2527\100 = 25.27

Use the subscript button in the ribbon.

If you use 4/3 of a tin for each door that is more than one whole tin.

They must be BIG doors.

4/3*7= = 9.3333333333333333

So 10 cans will be needed.

Yes you are correct pro35.  You are also extremely rude.

You will not win any friends here by being so incredibly rude!

Melody's answer should be:    x < -2    and  x > 3/2

See the graph, here :  https://www.desmos.com/calculator/afq8ukmpam

We need to solve this  for t

10800  = 5400e^(.072 * t)    divide both sides by 5400

2 = e^(.072 * t)      take the ln on both sides

ln 2   =  ln e^(.072 * t)     and, by a property of logs, we can write

ln 2 = (.072 * t)  * ln e       and since ln e   = 1, we can ignore this

ln 2  = .072t    divide both sides by .072

ln 2 / .072   = t  = about 9.6 years

BTW.......the time required for any investment to double at this interest rate is not dependent upon the size of the original investment.....!!!!

We have one of our best answerers  on this one.......he's very good with "Zs" :

you're wrong

the lines didn't touch -2 or 1.5

if you are not agreeing with me

okey let's see

\(\frac{4-2+3}{2*(-2)^2+(-2)-6}\)

5/0 , is that even possible?

T(20) = 38 + 43e^(-0.58 * 20)   = about  38°

(7 + 4i)^2   =

(7 + 4i) (7 + 4i)   =

49 + 28i + 28i  +  16i^2   =

49 + 56i +  16(-1)   =

49 +   56i  -   16  = 

33 + 56i

2000 = Pe^(r * t)       where r = .0025  and t = 3

2000  = Pe^(.0025 * 3)       divide both sides by  e^(.0025 * 3)

2000/e^(.0025 * 3)   = P   = about $1985.06

sin (pi/3)   =   √3/2

So

-sin (pi/3)   =   -√3/2

4 8/9th - 2 5/6th

4+ 8/9   =  44/9

2 + 5/6  =  17/6       

So we have

44/9 - 17/6      get a common denominator  of 18

88/18   - 51/18  =

37/18   =   2 + 1/18

Distance=Actual Diameter / Angular Diameter:
