et H be the set of all vectors of the form [Start 3 By 1 Matrix 1st Row 1st Column 4 t 2nd Row 1st Column 5 t 3rd Row 1st Column 9 t EndMatrix ]. Find a vector v in set of real numbers R cubed such that Upper H equals Span StartSet Bold v EndSet. Why does this show that H is a subspace of set of real numbers R cubed?

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
