1. Dilate A Using P As The Center Of Dilation And A Scale Factor Of 3. Label The New PointA'.2. Dilate

Answers

Answer 1

Answer:

Step-by-step explanation:

Rule for the dilation of a point by a scale factor 'k',

(x, y) → (kx, ky)

If we impose this rule in this problem,

k = [tex]\frac{\text{Distance of A' from P}}{\text{Distance of A from P}}[/tex]

1). If k = 3

   Therefore, Distance of A' from P = 3(Distance of A from P)

   And point A' will be on the third circle.

2). If k = 2

   Distance of B' from P = 2(Distance of B from P)

   Since, B is on circle 2, B' will be on circle 4.

Now we can plot these points A' and B' on the graph.

1. Dilate A Using P As The Center Of Dilation And A Scale Factor Of 3. Label The New PointA'.2. Dilate
Answer 2

After the dilation point A becomes A' and it is at a distance of 3 units from point P and after the dilation point B becomes B' and it is at a distance of 2 units from point P.

1)

Given :

Dilate A using P as the center of dilation and a scale factor of 3.

Let the coordinates of point A be (x,y) then after dilation point A becomes A'(3x , 3y). So, the distance of the point A' from the point P is 3 units

2)

Given :

Dilate Busing P as the center of dilation and a scale factor of 2.

Let the coordinates of point B be (x',y') then after dilation point B becomes B'(2x' , 2y'). So, the distance of the point B' from the point P is 2 units

Answer:

Between 9 and 10

Step-by-step explanation:

Area = 95 square feet

The garden is a square

Find the area of the trapezium BEFC.

Answers

Answer: 90,75. cos 55°. sin55° ≈ 42,64

through E, draw EK perpendicular to BC (F ∈ BC)

because E is the midpoint of AB => BE = 11/2 = 5.5

ΔBEF is a right triangle at K

=> sin 55° = EK/BE

=> EK = 5,5.sin 55°

ΔABC has E and F is the midpoints of AB and AC

=> EF is  the median line of the triangle

=> EF = 1/2.BC

through A, draw AD perpendicular to BC

=> ΔABD is a right triangle at D

=> BC = 11.cos 55°.2 = 22.cos 55°

=> EF = 11.cos 55°

=>the area of the trapezium BEFC is:

[tex]\frac{5,5.sin55(11.cos55+22.cos55)}{2}=90,75.cos55.sin55[/tex]

Answer:

rigidnon-rigidnon-rigidrigid

Step-by-step explanation:

The transformations of 1 and 4 are translations (1 and 4) and reflection (4), so are rigid transformations.

The transformation of 3 is a dilation by a factor of 3, so is non-rigid.

The transformation of 2 is a horizontal stretch by a factor of 2 and a vertical stretch by a factor of 3. It, too, is a non-rigid transformation, but is not strictly dilation.

I have a problem, it says, identify the set of numbers that best describes each situation. The situation is, the amount of money in a bank account. we are working with, real, rational, irrational, integers, and whole numbers. Is it irrational or rational? ​

Answers

Answer:

Rational

Step-by-step explanation:

We first have to define what these numbers mean:

Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.

Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.

An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....

Integers are real numbers that are whole numbers.

Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.

Answers

Explanation:

Cost of 1 loaf of bread = $4

Cost of 1 roll = $1

The baker needs to sell both items and it should be worth $36.

To find the linear equation, Suppose, the baker sells "b" loaves of bread and "r" rolls.

Then the total cost of the sales has to be $36.

So, the linear equation will be:

And if that is not what you are looking for here:

Rewrite the equation as  

x /14 =  5/ 7 .  x/ 14 =  5/ 7

Multiply both sides of the equation by
