Plz I'm sooooo confuzzled: If you reflect any shape across the x-axis and then across the y-axis, do you get the same result that you would if you rotated it 180° about the origin? What does that mean?

Answers

Answer 1

Answer:

the answer is true

Step-by-step explanation:

If the shape is in the upper left quadrant then you reflect it across the x-axis it would be in the lower left quadrant, next you reflect across the y-axis it would be in the lower right quadrant, finally, if you rotate it 180 degrees it would be where it started.

Answer 2

Answer:

it's correct because even though rotating 90° is not the same as reflecting about the y-axis, when you reflect again about the x-axis, it becomes the same as reflecting an additional 90°.

so reflecting about y and then about x is the same as rotating 180°.

Step-by-step explanation:

if you reflect (x, y) in 180° it becomes (-x,-y)

when you reflect about the y-axis, (x,y) becomes (-x,y).

when you reflect again about the x-axis, (-x,y) becomes (-x,-y) which is the same as the 180°

Zeno jumped 8 meters. Then he jumped half as far again (4 meters). Then he jumped half as far again (2 meters). So after 3 jumps, he was 8 + 4 + 2 = 14 meters from his starting place.



a. Zeno kept jumping half as far again. How far would he be after 4 jumps?

Answers

14/2 = 7

7/2 = 3.5

3.5/2 = 1.75

1.75/2 = 0.875

9514 1404 393

Answer:

  15 meters

Step-by-step explanation:

Zeno's last jump was 2 meters, so another jump half as far adds 1 meter to the 14 m total.

After 4 jumps, Zeno would have jumped 15 meters from his starting place.

Comment on the question

The given distances give a total "after 3 jumps." The question asks for a total "after 4 jumps." It is not clear whether that is 4 jumps total, or 4 more jumps. In the above, we have assumed it is 4 jumps total.

Five friends ate lunch together. They each paid the same amount the total cost of all five meals was $51.94 which included a 6% sales tax, what was the cost of one meal before tax was added?

Answers

Given:

Total number of friends = 5

Total cost of all five meals = $51.94

Sales tax = 6%

To find:

The cost of one meal before tax was added.

Solution:

Let x be the cost of all five meals before tax.

Then, Amount of tax = 6% of x

According to he question,

[tex]x+\dfrac{6}{100}x=51.94[/tex]

[tex]x+0.06x=51.94[/tex]

[tex]1.06x=51.94[/tex]

Divide both sides by 51.94.

[tex]x=\dfrac{51.94}{1.06}[/tex]

[tex]x=49[/tex]

So, the cost of all five meals before tax is $49.

Divide this cost by 5 to get the cost of one meal before tax was added.

[tex]\dfrac{49}{5}=9.8[/tex]

Therefore, the cost of one meal before tax was added, is $9.8.

(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.

Answer:

D. The relation represents y as a function of x, because each value of x is associated with a single value of y

Step-by-step explanation:

As long as no one x-value has two solutions, it can be considered a function. The x-values are {0, 2, 4, 6, 8}. Since there isn't any repetition, this can be considered as a function. The fact that 10 is repeated in the y-values doesn't affect that it is a function.

Answers

Answer:

Step-by-step explanation:

Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0

f(m)=20-0.25m

0 =20-0.25m

-20 = -0.25m

m = -20/-0.25

m = 80

Hence Trudy will have talked for 80minutes if she has no money left

What is the value of the expression 5y² + 4x when x = 2.5 and y = 3?

Answers

Answer:

55

Step-by-step explanation:

the value of the expression 5y² + 4x when x = 2.5 and y = 3 will be 55.

What is expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given an expression 5y² + 4x

To calculate the value of expression at x = 2.5 and y = 3

Substitute the value of x and y in the expression:

=> 5y² + 4x

=> 5* 9 + 4 * 2.5

=> 45 + 10

=> 55

therefore, 55 is the value of the expression 5y² + 4x when x = 2.5 and y = 3.
