f(x) = 2x + 5
and
g(x) = x2 - 25
So to find g( f(x) ), replace every x in g(x) with f(x) .
g( f(x) ) = (2x + 5)2 - 25
g( f(x) ) = (2x + 5)(2x + 5) - 25
g( f(x) ) = 4x2 + 10x + 10x + 25 - 25
g( f(x) ) = 4x2 + 20x
f2 - 79 = -15
Add 15 to both sides.
f2 - 64 = 0
This is now a "perfect square binomial," and you can write it like this:
(f - 8)(f + 8) = 0 :)
oh.
It showed that it didn't post the first time for some reason
Ummm CPC you posted the same thing twice...
Put a decimal on the end, then move it two digits to the left. The answer in your case is .15
Couldn't handle the competition of course...new I was smarter than him dint he...knew everyone would figure out efore long dint he...coulnt take the competition could heh...so he musta upped and left...smart move on his part I must say
Who hasnt been on for a while?
What do you mean by break?
Indeed he was my only competition...makes me sad to see him break like that...just couldn't take the pressure
He has been absent for quite a while now...
You multiply the number by itself.
So, using the pathagoreum therum, we can see that the slant height of the pyramid is 186.6387. Now, we use that info to plug into the formula for lateral area, and see that the lateral area is about 85853 square Meters. So, the answer is C
0.625
