If h(x) = 1/2x4 - 3x3, find h(4).

The answer is -64

Step-by-step explanation:

h(4)=(1/2)(4^4)-3(4)^3

1/2*4^4=1/2*256=128

-3(4)^3=-3(64)=-192

128-192=-64

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
