The coefficient of xy in the product of (4x^2+2y) and (3x+y^2) is ...
LUCKY_DIMON [66]
Here is your answer! The coefficient of xy is 6. To solve this problem, you need to multiply your two polynomials together. I used the FOIL Method- multiply the First two, the Outside two, the Inside two, and the Last two. You can see how I did it on the picture attached. Next, the answer that you get as a result from FOILing is your polynomial. If you look at the number before xy, that is the coefficient. A coefficient is a number that is right before and attached to a variable. I hope this helps you! :))

Ella swims four times a week at her club's pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps
ZanzabumX [31]

Answer:

Equation for the problem

3x + 15 = 51 laps

Hence

She swims on

Monday: 12 laps

Wednesday : 12 laps

Friday = 12 laps

Step-by-step explanation:

Ella swims four times a week at her club's pool.

We are told that:

She swims the same number of laps on Monday, Wednesday, and Friday.

Hence, the number rod times that she swims on Monday, Wednesday and Friday is represented by x

Also, she swims 15 laps on Saturday. She swims a total of 51 laps each week. Equation for the problem

= x + x + x + 15 = 51 laps

3x + 15 = 51 laps

Hence

3x = 51 - 15

3x = 36

x = 36/3

x = 12 laps

Therefore, She swims on:

Monday: 12 laps

Wednesday : 12 laps

Friday = 12 laps

Start with Chanel’s sequence. How does a 90-degree counterclockwise rotation about the origin change the coordinates of a shape?
zmey [24]

When a shape is rotated, it must be rotated through a point.

  • <em>90 degrees counterclockwise rotation negates the y-coordinates, and then swap the x and y-coordinates</em>
  • <em>Chanel is incorrect</em>

The rule of 90 degrees counterclockwise is:

(x,y) \to (-y,x)

This means that:

  • <em>The y-coordinate is negated</em>
  • <em>Then the y and x coordinates are swapped</em>

<em />

However, Charlies transformation is incorrect.

  • This is so because, the shape was not rotated, but instead it was reflected  across the x-axis.
  • Then, the shape was dilated

Using points L and Q

L=(1,1)

When L is reflected across the x-axis.

The rule is:

(x, y) \to (x, -y)

So, we have:

(1, 1) \to (1, -1)

Next, it is dilated by 2.

The rule of this is:

(x,y) \to k(x,y)

So, we have:

(1,1) \to2 \times  (1,-1)

(1,1) \to (2,-2)

From the diagram, the coordinate of Q is:

Q = (2,-2)

Same as the calculated point

Hence, Chanel is incorrect
