A rectangle lengths 12m and 17m and is dilated using the dilation (x, y) -> ( 0.4 x, 0.4y). What is the perimeter of the dilated rectangle?

Answers

Answer 1

Answer:

Perimeter of the dilated rectangle = 23.2 m

Step-by-step explanation:

If a point is dilated by a scale factor = k

Coordinates of the image point after dilation will follow the rule,

(x, y) → (kx, ky)

From the given rule,

(x, y) → (0.4x, 0.4y)

Which reveals that the figure has been dilated by a scale factor = 0.4

Length of the rectangle = 12 m

Width of the rectangle = 17 m

If the given rectangle is dilated by a scale factor of 0.4,

Length of the image rectangle = 12 × 0.4 = 4.8 m

Width of the image rectangle = 17 × 0.4 = 6.8 m

Perimeter of a rectangle = 2(length + width)

Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)

                                                                           = 23.2 m

Nicole played cards with her brother. She won 6 times as many games as she lost. Nicole won 18 games. If there were no ties, how many games did Nicole play?

Answers

Answer:

21

Step-by-step explanation:

Let x represent the number of times she lost

If she won 6 times as many games as she lost. The number of times she won can be represented as 6x

6x = 18

the number of games she lost = 18/6 = 3

Number of games played = 18 + 3 = 21

Answer:

4u^3 + 6u^2 - 7u + 9

Step-by-step explanation:

(2u3 + 6u2 + 3) + (2u3 – 7u + 6)

Remove the brackets.

2u^3 + 6u^2 + 3 + 2u^3 - 7u + 6

2u^3 + 2u^3 = 4u^3

6u^2

- 7u

What is the quadratic function for this graph?

Answers

Answer:

f(x) = (x + 3)² + 2

Step-by-step explanation:

Vertex for of a quadratic function is given by,

f(x) = a(x - h)² + k

Here, (h, k) is the vertex of the parabola.

From the given picture,

(-3, 2) is the vertex of the graph.

Therefore, function will be,

f(x) = a(x + 3)²+ 2

Since, the graph of the function passes through (0, 11),

f(0) = a(0 + 3)²+ 2

11 = 9a + 2

9a = 9

a = 1

Equation of the function,

f(x) = (x + 3)² + 2

Hi can someone plss help with this question!!!

Answers

Answer:

Function A < Function B

Step-by-step explanation:

Solving for Function A:

Taking two points: (0,1) and (4,2)

y = mx+c

Substituting (0,1):

1 = 0 + c

c = 1

Substituting (4,2):

2 = 4m+c

Substituting 'c':

2 = 4m + 1

4m = 1

m = 0.25

Comparing slopes (slopes of each - 0.25 and 0.75):

0.75 > 0.25

Hence,

Function A < Function B

Answer:

the answer is d

Step-by-step explanation:

so for one do y-intercept has to be at (0,25) so we can eliminate answer choices B and C

the reason why it is not a is because a is moving out of constant rate of 25 when it needs to be moving at a constant rate like 10 D is the answer because it's moving at a constant rate of 10 and it has a y intercept of (0,25)

The answer is graph D

It starts out at 25 and each week the graph goes up only 10 dollars, so it’s the only one that makes sense. Good luck!!!
