46.75 - 0.10(46.75) = 46.75 - 4.675 = 42.075 rounds to 42.08
ur simply taking ur discounted price of $ 46.75 and subtracting 10% of 46.75....leaving u with a final price of 42.08

Answer:


Step-by-step explanation:

The final price will be the discounted price multiplied by 100% — 10%. I could also multiply the discounted price by 0.10 and subtract that amount from the discounted price to get the final price.

The point (-4,0) is rotated 180 degrees counterclockwise using center (0,0). what are the coordinates of the image?
jenyasd209 [6]

Answer:

The new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).

i.e. [(-4,0)→(4,0)]

Step-by-step explanation:

The rule for rotation a point 180° counterclockwise about the origin states that when a point (x, y) is rotated 180° counterclockwise about the origin, the new position of the coordinates of point P(x, y) becomes (-x, -y).

Hence,

  • Rotate (x, y) counterclockwise 180° about the origin: [(x,y)→(-x,-y)]

So, when the given point  (-4,0) is rotated 180 degrees counterclockwise using center (0,0), the new coordinates of the image will be:

  • Rotate (-4, 0) counterclockwise 180° about the origin: [(-4,0)→(4,0)]

Therefore, the new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).

i.e. [(-4,0)→(4,0)]

Keywords: rotation, origin, image

If set A = (3,4,7,9) and if set D = (9,4,3,7), A=D.<br> True<br> O False
Nata [24]

<u>Answer:  </u>

<em>If set A = (3, 4, 7, 9) and if set D = (9, 4, 3, 7) , then </em><em>set A = set D</em><em> is </em><em>true</em><em>.</em>

<u>Solution:  </u>

Two sets are said to be equal, if the elements in both the sets are exactly same.

From question, the given sets are  

Set A = (3, 4, 7, 9)

Set D = (9, 4, 3, 7)

Set A and Set D contain same elements. In sets and relations, we need not worry about the elements positions. For the given set A the elements are {3,4,7,9} and  for set D the elements are {9,4,3,7}. The elements are same each other irrespective of their positions. Hence, the given condition  set A= set D is True.

The musical note E can be modeled by the function, y = asin(1320πx), where a = 1 and x is the time in seconds. Playing note E on
Taya2010 [7]

Using translation concepts, the note E would be louder with a higher amplitude of y, hence constant a has to be multiplied by a positive constant greater than 1.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the function is given by:

y = asin(1320πx)

The intensity of a sound is given by it's amplitude a, hence, to make the sound stronger, we need to vertically stretch the graph of y, which is done when constant a is multiplied by a positive constant greater than 1.
