Area of a rectangle = L * W
200 * 100 = 20,000
= 20,000m^2
Convert that to km^2
= 0.02km^2

If the parabola y - 8 = 3(x - h)² has the line x = 5 as its axis of symmetry, find h.
Goshia [24]
h = 5 because if you added 8 to the other side of the equation, then the equation would be in vertex form, where the opposite of h, and the value of k (8) is your vertex. So, we know that the x-value of the vertex is also the axis of symmetry, so the axis of symmetry is also the x-value of the vertex, or h. 

Hope this helps! :)

Perimeter of rectangle = all sides added
= 3+3+7+7 =20


volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257

area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15

volume of pyramid = base height x base width x height / 3
= 300

side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5
