D. K = 8

B. 216

Step-by-step explanation:

Q. T varies directly as the square of P and inversely as Z and T=12 when P=3 and Z=6

Solution:

According to the given information:

T varies directly as the square of P.

T varies inversely as Z.

Combining equations (1) & (2)

(Where K is proportionality constant)

(This is the equation of variation)

Plug T=12, P=3 and Z=6 in the above equation of variation, we find:

So, the value of the variation constant = 8

Next, plug P=9, Z=6 and K = 8 in the above equation of variation, we find:

So, 216 is twice the value of T.

answer: the is put the 450

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
