If you're looking for f(x)

then 

g(x) = sqrt(4x + 4)
h(x) = sqrt(4x + 28)

h(x)-g(x) = 24

meaning that sqrt(24) must be the constant of f(x)

f(x) = x(sqrt(24))

h(x) = f(g(x)) = (sqrt(24))(sqrt(4x+4)) = sqrt(4x+4+24) = sqrt(4x+28)

Answer:

f(x) = \sqrt[4]{x+6}

Step-by-step explanation:

Let h(x) = \sqrt[4]{x+7} and g(x) = \sqrt[4]{x+1}. By some algebraic handling:

h(x) = \sqrt[4]{(x+1)+6}

h(x) = \sqrt[4]{(\sqrt[4]{x+1} )^{4}+6}

But g(x) = \sqrt[4]{x+1}. Therefore:

f(x) = \sqrt[4]{x+6}

) find a vector parallel to the line of intersection of the planes 5x − y − 6z = 0 and x + y + z = 1.
snow_tiger [21]
The cross product of the normal vectors of two planes result in a vector parallel to the line of intersection of the two planes.

Corresponding normal vectors of the planes are
<5,-1,-6> and <1,1,1>

We calculate the cross product as a determinant of (i,j,k) and the normal products

    i   j   k
   5 -1 -6
   1  1  1

=(-1*1-(-6)*1)i -(5*1-(-6)1)j+(5*1-(-1*1))k
=5i-11j+6k
=<5,-11,6>

Check orthogonality with normal vectors using scalar products
(should equal zero if orthogonal)
<5,-11,6>.<5,-1,-6>=25+11-36=0
<5,-11,6>.<1,1,1>=5-11+6=0

Therefore <5,-11,6> is a vector parallel to the line of intersection of the two given planes.

If the diameter of his flower bed is 100 inches what is distance around the garden
Gala2k [10]
Well if pi is referred to as 3.14 then the distance around the garden would be 314.  
The formula for Circumfrence is pi times diameter, so 3.14 times 100 = 314 (circumfrence)
