What would be the coordinates of the image if this pre-image is reflected across the x-axis?

Mathematics

Dimas [21]3 years ago

Answer:  C   (-2, 2), (1, -1), (3, 1). (2,4)

It will help to rotate the image so the x-axis is horizintal and the y-axis is vertical.

Step-by-step explanation:

Imagine the prefigure twirling on a parallel bar like a gymnast.

When it's up-side down the point that was at  (1,1) flips to (1. -1) and the point that was at  (3 -1) flips to (3, 1)

As you chech your choices, that knocks out most of the other possibilities.

But you should still verify the other cocorinates.

Hint: if the reflection is across the x-axis, the x values will be the same in the pre-image and the reflection, the y- values will change accorfing to their distance from the x-axis.

A triangle is 3cm wider than it is tall. The area is 44cm^2. Find the width(length of the base).
stich3 [128]
Set height to x, then length of base is x+3, Area formula says that
0.5*x*(x+3)=44, x(x+3)=88, x=8, x+3=11, which is the length you are looking for (11cm)

1. Volume of 1 tennis ball = volume of sphere = 33.51 in.³

2. Volume of the cylinder = 150.8 in.³

3. Amount of space not occupied by the tennis ball = Volume of cylinder - 3(volume 1 tennis ball) = 50.27 in.³

<h3>What is the Volume of a Cylinder and Volume of a Sphere?</h3>
  • Volume of Cylinder = πr²h
  • Volume of Sphere = 4/3πr³

Diameter of the tennis ball = 4 in. (given)

1. Volume of 1 tennis ball = volume of sphere = 4/3πr³

r = 1/2(4 in.) = 2 in.

Volume of 1 tennis ball = 4/3π(2)³ = 33.51 in.³

2. Volume of the cylinder = πr²h

Radius of the cylinder (r) = 1/2(4 in.) = 2 in

Height of the cylinder (h) = 3(4 in.) = 12 in

Volume of the cylinder = πr²h = π(2²)(12) = 150.8 in.³

3. Amount of space not occupied by the tennis ball = Volume of cylinder - 3(volume 1 tennis ball)

= 150.8 - 3(33.51) = 50.27 in.³
