it is A hope this helps:)
I suggest drawing a graph or simply using a calculator
The answers should be (5 - √ 41) / 2 and (5 + √ 41) / 2
;)
Write down the two numbers, one under the other, with the decimal points lined up.
Add zeros so the numbers have the same length.
Then subtract normally, remembering to put the decimal point in the answer.
Due to the symmetry of the paraboloid about the <em>z</em>-axis, you can treat this is a surface of revolution. Consider the curve 
, with 
, and revolve it about the <em>y</em>-axis. The area of the resulting surface is then
But perhaps you'd like the surface integral treatment. Parameterize the surface by
with 
and 
, where the third component follows from
Take the normal vector to the surface to be
The precise order of the partial derivatives doesn't matter, because we're ultimately interested in the magnitude of the cross product:
Then the area of the surface is
which reduces to the integral used in the surface-of-revolution setup.
Answer:
Step-by-step explanation:
the answer is 8 because if you hv the equation 24/x equals 3 multiply both sides by x and u get 24=3x and then divide both sides by 3 and u get 8
