16x^2 + 9 = 0
16x^2 = -9 divide both sides by 16
x^2 = -9/16 take both roots
x =±√(-9/16) = ±√ [ -1 * (9/16) ]
x = ± (3/4) i ⇒ first answer
\(f(f(3)) + f(f^{-1}(4)) + f^{-1}(f^{-1}(5))\)
f (3) = 5
f(f(3)) = f (5) = 8
And f( f-1) (4)) = 4
And f-1 ( f-1(5) ) = f-1 (3) = 2
So
8+ 4 + 2 = 14
CORRECTED !!!!
[x^2 + 3x - 28] / [ x^2 - 7x + 12 ]
[ (x + 7) (x - 4) ] / [ (x - 4) ( x - 3) ] =
(x + 7) / ( x - 3)
-11x^2 = x + 11 rewrite as
11x^2 + x + 11 = 0
The discriminant is
1^2 - 4(11)(11) which is < 0
So.....anytime the discriminant < 0.....we have no real solutions
We want to solve this
[12 + x ] / [15 + x] = .85 where x is the consecutive number
Cross-Multiply
12 + x = .85 [ 15 + x ] simplify
12 + x = 12.75 + .85x subtract .85x, 12 from both sides
.15x = .75 divide both sides by .15
x = 5 ⇒ 5 consecutive FTs
Melody recommended me to be a mod....I didn't have much to do with it....LOL!!!!
Which question do you want to delete???......send me the link and I'll delete it for you
OK, ProMagma....ask away !!!!!
For the first one...look at this graph :

Max ht ≈ 6.2 cm
Length of jump ≈ 9.1 cm [second answer ]
(3 - i) - ( 2 + 6i) =
3 - 2 - i - 6i =
1 - 7i
HAHAHA!!!!!!....too bad we don't get any money for collecting points, huh ????
