y is directly proportional to (x-1)2.
When x = 3, y = 24.
Find y when x = 6.

Answers

Answer:

y = 150

Step-by-step explanation:

Proportions

It's given y is directly proportional to the square of x-1. It can be expressed as:

[tex]y=k(x-1)^2[/tex]

Where k is the constant of proportionality. We know y=24 when x=3. Substituting:

[tex]24=k(3-1)^2[/tex]

[tex]24=k(2)^2=4k[/tex]

Solving for k:

k = 24/4 = 6

Thus, the equation is:

[tex]y=6(x-1)^2[/tex]

When x=6:

[tex]y=6(6-1)^2=6(5)^2=6*25[/tex]

y = 150

Polygons QRST and Q′R′S′T′ are shown on the following coordinate grid:

A coordinate plane with two polygons is shown. Polygon QRST has vertices Q at 3 comma negative 5, R at 2 comma negative 1, S at 5 comma 0, and T at 5 comma negative 4. Polygon Q prime R prime S prime T prime has vertices at Q prime negative 5 comma negative 4, R prime at negative 1 comma negative 3, S prime at 0 comma negative 6, and T prime at negative 4 comma negative 6.

What set of transformations is performed on QRST to form Q′R′S′T′?

A 180-degree clockwise rotation about the origin followed by a translation 1 unit to the left
A translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin
A translation 1 unit to the right followed by a 270-degree counterclockwise rotation about the origin

Answers

Answer:

Step-by-step explanation:

I get a paper and trace out the shape and the for line. with the dot. I hold my find on the dot and I counter clockwise to 270 degrees its not directly on the shape so I move it 1 time and it ends up the second shape.

I first thought it was A but then realized that that one said you move it after the 180 tur the the right which would have been incorrect.

In right angled triangle ,

By pythagoras theorem

Hypotenuse ² = Base² + perpendicular ²

Given,

Hypotenuse = 5

Base and perpendicular both are x .

Now,Putting the values

=> (5)² = x² + x²

=> 5 = √2x²

=> 5 = x√2

=> x = 5/√2

Hence,the length of leg is 5/√2.

Verification:

Hypotenuse ² = base ² + perpendicular ²

=> (5)² = ( 5/√2)² + (5/√2)²

=> 25 = 25/2 + 25/2

=> 25 = 50/2

=> 25 × 2 = 50

=> 50 = 50

verified.

A plastic storage bin is shaped like a rectangular prism. The height of the bin is 9 inches. The bottom of the bin has an area of 180 square inches. What is the volume of the storage bin? Enter your answer in the box. in³

Answers

Answer:

1620in³

Step-by-step explanation:

Volume of a rectangular prism = BH

B is the Base area

H is the height of the prism.

Given

B = 180in²

H = 9in

get the volume of the prism

Volume of the prism = 180 * 9

Volume of the prism = 1620in³

Hence the volume of the rectangular prism is 1620in³
