Suppose f(x) = ----------
                          sqrt(x) 
                                                                                                   8
What if we let x = 16 (just an example)?  We'd get f(16) = ------------- = 2.
                                                                                              sqrt(16)

What if we let x = g(x) = 2x+4?

We'd get the following:

                     8
f(g(x)) = -------------- = y
              sqrt(2x+4)

So...the correct answer is the fourth one.

What's the difference between 6z and z6
Airida [17]
Simple..

there is a major difference between 6z and z^{6}

6z means: 6 times z

and

z^{6} means: z to the power of 6(z*z*z*z*z*z)

An example...

make z=2...plug n chug..

6z----> 6(2)=12
and
z^{6}--->2^{6}=64

As you can see..there is a major difference.

Thus, your answer.

PLEASE HELP ASAP!!!!
adell [148]


The basic form of the equation is:
4p(x-h) = (y-k)2

(h,k) is the vertex


4(-0.5)(x-1.5) = (y-(-4))2
-2(x-1.5) = (y+4)2
-2(x-1.5) = y2 + 8y + 16
x - 1.5 = (-1/2)(y2 + 8y + 16)
x = (-1/2)y2 - 4y - 8 + 1.5
x = (-1/2)y2 - 4y - 6.5

LekaFEV [45]

Answer:

total = 1 \\  \frac{1}{2}  +  \frac{1}{7}  + x = 1 \\  \frac{1}{7}  + x = 1 -  \frac{1}{2}  \\  \frac{1}{7}  + x =  \frac{1}{2}  \\ x =  \frac{1}{2}  -  \frac{1}{7}  \\ x =  \frac{7 - 2}{7 \times 2}  \\ x =  \frac{5}{14}  \\  \\ shaded \: portin \:  =  \frac{5}{14}  \\ thank \: you
