A transformation T : (x, y) → (x + 3, y + 1). Find the preimage of the point (4, 3) under the given transformation. (7, 4) (1, 2

motikmotik

Answer:

(1, 2)

Step-by-step explanation:

Remember that the final shape and position of a figure after a transformation is called the image, and the original shape and position of the figure is the pre-image.

In our case, our figure is just a point. We know that after the transformation T : (x, y) → (x + 3, y + 1), our image has coordinates (4, 3).

The transformation rule T : (x, y) → (x + 3, y + 1) means that we add 3 to the x-coordinate and add 1 to the y-coordinate of our pre-image. Now to find the pre-image of our point, we just need to reverse those operations; in other words, we will subtract 3 from the x-coordinate and subtract 1 from the y-coordinate.

So, our rule to find the pre-image of the point (4, 3) is:

T : (x, y) → (x - 3, y - 1)

We know that the x-coordinate of our image is 4 and its y-coordinate is 3.

Replacing values:

(4 - 3, 3 - 1)

(1, 2)

We can conclude that our pre-image is the point (1, 2).

A fish tank, in a shape of rectangular prism, measures

murzikaleks [220]

Answer:

The deep of the water would be 20 cm

Step-by-step explanation:

step 1

Find the volume of the water

The volume of the water is equal to

$V=LWH$

we have

$L=60\ cm\\W=40\ cm\\H=50/ cm$

substitute

$V=(60)(40)(50)$

$V=120,000\ cm^3$

step 2

Find the deep of the water, if the tank is returned to its horizontal position

(resting on its 60 cm × 100 cm base)

Now we have

$L=60\ cm\\W=100\ cm\\H=?\ cm$

$V=120,000\ cm^3$

substitute the given values

$120,000=(60)(100)H$

solve for H

$H=120,000/6,000$

$H=20\ cm$

therefore

The deep of the water would be 20 cm

9(9h + 4b +9), for h = 7 and b =3

Elanso [62]

Simplified that would be: 9(63+12+9) which if you add everything in the brackets, 9(84) which would be 9 times 84=756
