Note, DS :
The area left for the square must be [60.5 - 44.5]ft^2 = 16 ft^2
So....the area of a square = side^2
So we have
side^2 = 16 take the square root of each sides
side = 4 ft
Example:
"Split" the coefficient parts and the exponential parts, thusly :
[6.05 x 10^5] / [3.28 x 10^-3 ] =
[6.05 / 3.28] x [ 10^5 / 10^-3] ≈
1.88 x [ 10^(5 - -3) ] ≈
1.88 x 10^8
This says that when we substitute -4 into one of the functions for x, the result is -61.
In this case, B is correct......
It's OK, DS.....you and Spawn still got 5 pts. from me.....LOL!!!!
14log ????
What are we taking the log of ???
If you are talking about separately.....the chances of winning the first is .03 and the chance of winning the second is about 5/150 = 1/30 = about .033
If you are talking about winning both, then the answer is .03 * .033 = about .0099 = about .01 rounded = 1% chance
2x^2-7x+5=0 factor
(2x - 5) (x -1 ) = 0
Set each factor to 0
2x - 5 = 0 and x - 1 = 0
add 5 to both sides add 1 to both sides
2x = 5 x = 1
divide both sides b 2
x = 5/2
So.....the two answers are x =5/2 and x = 1
.25^x = 2.5 take the log of both sides
x log (.25) = log(2.5) divide both sides by log (.25)
x = log(2.5) / log (.25) = about -0.66
-27352 * x = 163836280
x = 163836280 / -27352 = about -5989.92
There will be 16 days of rise and 15 days of fall....so we have
1000(1.20)^16 * ( .80)^15 = about $650.50 = amount stock was worth when he sold it
