Infinity.

(-1/4) * (-4) =

-1/4 * (-4/1) =

4/4 = 1

Take LOG of both sides:

LOG (e^(-.0246)) = LOG( .9757)

-.0246  LOG(e) = -.0106836              Divide both sides by -.0246

LOG(e)=.43429                                  Anti-log both sides :  10^(LOG(e)) = e    

e=2.71829

You'll have to have the same denomintor to add or SUBTRACT fractions...

1 2/7 = 36/28

36/28  -  15/28 = 21/28 = 3/4

What's  33 = 99/22 ???  

A MISTAKE !

Did you leave something out?

wills score = 483 + 18x

Tom's score = 462 + 21x      where 'x' = number of games

When will they be equal?

483 + 18x  = 462 + 21x

21 = 3x

x=7    more games and they will be equal  

y = mx+b

y= 56 (8) + b

-4 = 448 + b       so b = -452

y = 56 ( x -8)  - 4

 or, re-arranging:

y+4 = 56 (x-8)

The pole forms one leg of a right traingle, whose opposite angle is 50 degrees

the top of her shadow is 8 + 15 = 23  feet away from the base of the pole and is the OTHER leg of the right triangle

Tan 50 = opposite/23

23 tan50 = opposite = light pole height =27.41 ft

(79 1/3 - 24 1/4) / 2  =   27.54 cm
