What’s point B’ <br> What’s point C’ <br> After being dilated by a scale factor 1.5?

Dimas [21]

Given:

The given figure is dilated by a scale factor 1.5.

To find:

The coordinates of B' and C'.

Solution:

If a figure is dilated by a scale factor k at point (a,b), so the rule of transformation is

$(x,y)\to (k(x-a)+a,k(x-b)+b)$

From the given figure it is clear that A(3,-3), B(-2,2) and C(-3,-5).

The figure is dilated by a scale factor 1.5 at point A(3,-3), so the rule of transformation is

$(x,y)\to (1.5(x-3)+3,1.5(x-(-3))+(-3))$

$(x,y)\to (1.5(x-3)+3,1.5(x+3)+(-3))$

$(x,y)\to (1.5(x)-4.5+3,1.5(x)+4.5-3)$

$(x,y)\to (1.5x-1.5,1.5x+1.5)$

Using this rule, we get

$B(-2,2)\to B'(1.5(-2)-1.5,1.5(2)+1.5)$

$B(-2,2)\to B'(-3-1.5,3+1.5)$

$B(-2,2)\to B'(-4.5,4.5)$

And

$C(-3,-5)\to C'(1.5(-3)-1.5,1.5(-5)+1.5)$

$C(-2,2)\to C'(-4.5-1.5,-7.5+1.5)$

$C(-2,2)\to C'(-6,-6)$

Therefore, the coordinates of B' and C' are B(-4.5,4.5) and C'(-6,-6).

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

lord [1]

Answer:

Number of books = 4480.

Step-by-step explanation:

Given that fixed cost = $45920

Given that variable cost = $11.25 per book

Let number of books = x

then cost equation is given by 11.25x + 45920

Given that selling price of 1 book = $21.50

then selling price is given by 21.50x

Now we need to find about how many books must the publisher produce and sell so that the production costs will equal the money from sales.

So let's set both equal

21.50x = 11.25x + 45920

21.50x - 11.25x = 45920

10.25x = 45920

x = 45920/10.25

x = 4480

Hence number of books = 4480.

<h3>What does unit conversion entail?</h3>

The process of translating measurements of a given quantity between different units, frequently using multiplicative conversion factors that change the value of the measured quantity without changing its effects, is known as unit conversion. The specific circumstances and the desired result dictate the conversion process. This may be governed by a regulation, contract, set of technical requirements, or other publicly available standards.

<h3>Why is the unitary technique used? What is it?</h3>

In its simplest form, the unitary procedure is used to determine the value of a single unit from a given multiple.

How to calculate the value of one pen, for example, if 40 cost Rs. 400. To finish it, using the unitary method. Additionally, after the value of a single unit has been established, we can multiply that value by the quantity of additional units required to establish the value of the additional units. This is typically how the concepts of ratio and proportion are used. The unitary method entails calculating the value of a single unit before calculating the value of the required number of units.

Given that 0.429 kg of cheese cost $9.50

As a result, the price of 1 kg of cheese is $9.50/0.429, which is $ 22.14.

As a result, 1.42 kg of cheese will cost you $22.14 * 1.42 = $31.44.
