As someone put it:

" An error does not become a mistake until you refuse to correct it. "  

thank you!

Sorry,  Your answer is correct.

Good work.

Use law of cosines

c^2 = a^2 + b^2 - 2ab cos 63^o         c is the distance you are looking for    a = 80   b=140      solve for 'c'

would it be 33/65 ?

y<2x-4

You can rearrange it.

Excellent!  So I did indeed misinterpret the question.

T = Tahoe days          cost   350 T

9-T = S                      cost   475 (9-T)      summed  = 3650

350 T        +      475 (9-T)        = 3650             solve for T (Tahoe days)     then # San Fran days  =   9 -T

Yes, better.

I think it will be at its biggest when the two numbers are as close in value as possible.

And it will be at its smallest when the two numbers are as far apart as possible.

You can do it now.

ok, thanks for answering :)

Here is a possibility

Stack A has     6 red 24 black

Stack B has     20 red 2 black    =  22 cards in stack B

2c +4a =38

14c +12a = 138      multipy top equation by  -3

-6c -12a = -114      add to the second equation

8c           = 24         solve fo c....

58 of them so far this year        58/72 x 100% = 80.56 %

Take 1/2 of the 'x' coefficient     11  * 1/2 = 5.5     now square it and add it to both sides of the equation (the blanks in your question)

5.5²  = 30.25

y = mx +b    is slope intercept form    m = slope    b = y intercept     put in the values you are given for m and b and you are done !

Trig identity:

tan²(x)=    ( 1-cos(2x) )  / ( 1+cos(2x) ) ​

x+y = 51

x-y = 25     add the two equations

2x = 76

x = 38              Now you should be able to find 'y'

Distance east =   250 +  115 cos (-25)

   distance south = 115 sin (-25)                             (in this situation the - signs are really not needed)

Then Use Pyrthagorean theorem to find the

          RESULTANTdistance =   sqrt (  (250 +115 cos25)^2     +      (115 sin 25)^2  )

(30000!) / ((30000-6000)!*(6000!))=2.634033676257152497742842 * 10^6517

Better?

Thanks for helping!

The numbers 1, 2, ..., 10 are to be entered into the 10 boxes shown below, so that each number is used exactly once: \(P = (\square + \square + \square + \square + \square)(\square + \square + \square + \square + \square).\)What is the maximum value of P? What is the minimum value of P?

What do you mean?
