That's wrong :/

24 blond /( 50+24+5+17) people   x 100% = ......... % with blond hair

Well, I'm late. But if other people is stuck on this problem and want a hint, here's one: 

the denominator (x^2+2 in this case) can't equal 0 because then it would be undefined. 

This looks like a math question, but can you please translate this into English? 

Or maybe write the equation without latex? because some latex doesn't seem to show and most latex under square roots don't show here. I tried it before. 

If @OP didn't use latex, then I guess the equation would be: f(x) = arctan(cosx)/arcsin(1-2xsqrtf'(0)

The point of tangency  is  the center of the  rectangle   =  ( 50,25)

The center of the  circle on the top left  =   (r, 50)    where  r is the  radius

So  the  distance  from  ( r, 50)  to  (0 ,50)  =   the distance from (r , 50)  to  (50,25)

Using  the  square of the distance  formula we have that

r^2   =   (r  -50)^2  +  ( 50 -25)^2

r^2  = r^2  - 100a  + 2500  +  625

100r  =  3125

r =   31. 25  = the radius

11 pages / 1/2 hr   =   11 * 2/1   pages/hr = 22 pages/hr

@asinus: A reciprocal is most likely a fraction so 1.4 as a fraction is 14/10 = 7/5 (simplified fraction)

since 1/2 hour is half of 1 hour: 

then simply multiply 11 by 2 to get the answer which is 22

idk?

At t= 0 it is at    0,0

at t= 4 it is at    4,8

use distance formula or pytheg theorem to find d

d² = 4²   + 8²        ........finish.....

I know  a few

a)  Here are both graphs :   https://www.desmos.com/calculator/lzspxc52ys

b)   and c).....the line of symmetry is  x  = -1    ( I believe this is also the mirror line )

d) (x + 4) /(x -2)   has no interval of  increase  ...it decreases on (-inf, -2)  and (-2, inf)

Conversely  ( -2) /(x + 4)  has no interval of  decrease  ....it increases  on ( -inf, -4)  and (-4 , inf)

e)  Sorry.....I do not know the answer to this one......

Right triangle   sin = opposite/hypotenuse     guy wire is hypot       tree height is opposite

sin 61^o = height / 10   

10 sin 61^o = height        ....continue

.18x =  $ 9

x = 9/.18 = total dinners' cost = $ 50      David's dinner:  $ 50 - 28 = $22

First find the midpoint      1, 6

find the slope between the lines   (y1-y2)/(x1-x2) =   -1/2      perpindicular slope = 2

point slope form    y-6 = 2(x-1)    re=arrange

                              y = 2x +4       continue.....

svar jeg tror det er 60$%er flododre

Update: Solved it!. The answer was 7.2. So sorry for wasting your time!

point b is located at (4,-16). Where is b' after a dialation with a scale factor of 3/4

idk'

Call the cost of David's dinner D.  

9  =  0.18 • (D + 28)       The tip equals 18% of the total of David's and Anna's dinners.

9  =  0.18D + (0.18 • 28)  

0.18D  =  9 – 5.04           I switched sides because I like the unknown on the left.  It's a personal preference. 

0.18D  =  3.96  

          3.96  

D  =  ———  =  22           David's dinner cost $22.00  

          0.18

x(1.5)(2^nd)  = 8x

1.5 (2^nd) = 8

2^nd = 8/1.5

2^nd  = 5 .3333       which is a 433.33% increase
