Answer:

The second one: r x-axis. R 90(x,y)

Step-by-step explanation:

You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.

The vertices of a polygon are P(0,4), Q(5,4), R(5,−3) and S(0,−3). What is
andrezito [222]

Answer:

 Perimeter of the polygon p = 24

Step-by-step explanation:

Step(i):-

Given the vertices of a polygon are

P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)

The distance of PQ

 a = PQ = \sqrt{(4-4)^{2} +(5-0)^{2} }  = \sqrt{25} =5

The distance of QR

b = Q R= \sqrt{(-3-4)^{2} +(5-5)^{2} }  = \sqrt{49} =7

The distance of RS

c = RS = \sqrt{(0-5)^{2} +(-3+3)^{2} }  = \sqrt{25} =5

The distance of PS

d = PS = \sqrt{(0-0)^{2} +(-3-4)^{2} }  = \sqrt{49} =7

<u><em>Step(ii):-</em></u>

Perimeter of the polygon

       = sum of all sides of polygon

p = a+ b+ c+ d

p = 5+7+5+7

p = 24

<u><em>Final answer:-</em></u>

 Perimeter of the polygon p = 24

Juan has a mass of 50 kg. If he is running at a velocity of 2 m/s, how much kinetic energy does he have?
VLD [36.1K]

Answer:

  100 J

Step-by-step explanation:

Kinetic energy is jointly proportional to mass and the square of the velocity.

  KE = 1/2mv²

  KE = 1/2(50 kg)(2 m/s)² = 100 J

Juan has a kinetic energy of 100 joules.
