Quadrilateral ABCD is dilated by a scale factor of 1 over 3 centered around (1, 2). Which statement is true about the dilation?
Sonbull [250]

<em>Note: Since you missed to add the figure. So, after a little research I am kind of able to find the figure and hence, assuming it as a reference. Hence, I am attaching the figure and solution of that figure is also visible in the same figure.</em> Please check the attached figure (a)

Answer:

Segment B'D' will be parallel to segment BD and will be shorter than segment BD. Please see the attached figure (a) for better understanding.

Step-by-step explanation:

As we know that there are certain rules when a quadrilateral is dilated by a certain scale centered around a certain point.

So,

Let suppose P(a, b) is the point.

The dilation rule by a scale factor of 1 over 3 or (1/3) centered around (1, 2) is

P(a, b) → P(\frac{x+2}{3}, \frac{y+4}{3})

Hence,

            A(1, 2) → A'(1, 2)

            B(2, 3) → B'(4/3, 7/3)

            C(4, 2) → C'(2, 2)

             D(2, 1) → D'(4/3, 5/3)

The attached figure show that if we draw the all these points in the coordinate plan i.e. A(1, 2), B(2, 3), C(4, 2), D(2, 1) and A'(1, 2), B'(4/3, 7/3), C'(2, 2), D'(4/3, 5/3), we can determine that Segment B'D' will be parallel to segment BD and will be shorter than segment BD.

What is 4 square root 7^3 in exponential form?
Gnesinka [82]

Answer:

Given the radical form: 4\sqrt{7^3}

Use the exponent rules:

\sqrt[n]{a^m} = (a^m)^{\frac{1}{n}} = a^{\frac{m}{n}}

we can write \sqrt{7^3} as:

\sqrt{7^3} = (7^3)^{\frac{1}{2}} = 7^{\frac{3}{2}}

then;

4\sqrt{7^3} = 4 \cdot 7^{\frac{3}{2}}

Therefore, 4\sqrt{7^3} in exponential form is 4 \cdot 7^{\frac{3}{2}}

scholars want to share 9 chocolate bars so that each scholar gets the same amount. How much chocolate bar will each scholar get?
bazaltina [42]

I'm not exactly sure how to answer this question without knowing the number of scholars. However, if you do know the number of scholars, you can divide that number by 9. The quotient will give you the amount of chocolate each scholar can receive.

The points (2a, – 4a + 3), (2b - 3, b) lie on the graph of the equation
vladimir2022 [97]

Answer:

  • a = -2.5, b = 1

Step-by-step explanation:

<u>Given line:</u>

  • y = -3x - 2

<u>Points on the same line:</u>

  • (2a, -4a + 3) and (2b - 3, b)

<u>Substitute x and y values of both points into equation of the line and solve for a and b:</u>

  • -4a + 3 = -3(2a) - 2 ⇒ -4a + 3 = -6a - 2 ⇒ 6a - 4a = -2 - 3 ⇒ 2a = -5 ⇒ a = -2.5
  • b = -3(2b - 3) - 2 ⇒ b = -6b + 9 - 2 ⇒ b+ 6b = 7 ⇒ 7b = 7 ⇒ b = 1
