Answer:−21x−8
Step-by-step explanation: All sides have the same measure in a square, therefore all sides are 3x-8. Area is equal to 3x-8 times 3x-8 which is −21x−8
Answer:
3rd one. Amsterdam is the same distance from sea level as Drachten.
Step-by-step explanation:
because Amsterdam is 2 below, and drachten is 2 above, but they are both 2 meters away from the sea level.
Answer:
Step-by-step explanation:
x^2 and -x^2 would cancel
and then it would be -7 = 1
it would be no solution
but I don't know, someone can prove me wrong I may have a lapse in my algebra at the moment
The cylinder is a clue to use cylindrical coordinates. Taking
and
, we then are forced to use
. So the parameterization of the intersection of the plane and cylinder is
To get the surface, we can introduce a second parameter
that "contracts" the elliptical intersection to a point. The simplest way to do this is to use
with
and
.
Answer:
(3,-3)
Step-by-step explanation:
If a coordinate (x, y) is dilated by a factor k, the resulting coordinate will be (kx, ky)
Given the coordinate (1, -1), if dilated by a factor of 3, the resulting coordinate will be (3(1), 3(-1)) = (3, -3)
Hence the required coordinate will be (3,-3)
