Answer: Choice A) Rectangle B'C'D'E' is larger because scale factor is greater than 1.

Going from (x,y) to (3x,3y) means we multiply each coordinate by 3. This is the scale factor. The scale factor being larger than 1 means the new image is an enlargement compared to the original preimage. Specifically the dimensions of the new rectangle are 3 times larger.

Answer:

$we \: have \: ohms \: law \: h = {i}^{2} rt \\ \frac{h}{t} = {i}^{2} rt \div t = p \\ p = {i}^{2} r....(1) \\ we \: have \: v = ir \\ i = \frac{v}{r} .....(2) \\ put \: (2) \: in \: (1) \\ then \: p = { (\frac{v}{r}) }^{2} r \\ p = \frac{ {v}^{2} }{r} \\ v = \sqrt{pr} = {(pr)}^{ \frac{1}{2} } \\ 2) \\ here \: r = 32 \: and \: p = .5 \\ then \: v = \sqrt{32 \times .5} \\ = \sqrt{16} = 4volt \\ thank \: you$
