To dilate an image with a scale factor, multiply the scale factor with the dimensions of the image

The dilation is the process of changing the size of the given shape or figure ,the shape of the figure will be always same. Therefore dilation is one form transformation of shapes

The scale factor is the ratio of the measurement of the new shape to the measurement of the original shape.

We can use the scale factor for the dilation

To get the dilate and image with scale factor, we have to multiply the scale factor with the measurement of the original shape

The equation will be

The dimension after dilation = scale factor × original dimensions

Therefore, to dilate an image, multiply the scale factor and the original dimensions

The largest figure that Ash can built with 61 toothpicks is of:

A composition of 12 hexagons.

The number of toothpicks needed is modeled with a linear function, defined as follows:

y = mx + b.

The coefficients of the function are given as follows:

The number of toothpicks in each figure is represented by the following sequence:

(6, 11, 16, ...).

Hence the parameters are given as follows:

m = 5, b = 6.

Thus the definition of the function is of:

T(n) = 5(n - 1) + 6. (as the first figure is with n = 1).

T(n) = 5n + 1.

Then the number of hexagons with 61 toothpicks is obtained as follows:

5n + 1 = 61

5n = 60

n = 60/5

n = 12 hexagons.

The earth is 21.24 x 10¹⁴ miles far from the star.

What are the light years?

A light-year is a significant length measure that is used to express astronomical distances. It is around 9.46 trillion kilometers, or 5.88 trillion miles, in length.

We have given,

1 light year = 5.9 x 10¹² miles

Distance of the star =  3.6 x 10² light years

To get this we just convert the distance of the star in light years into miles.

3.6 x 10² light years x( 5.9 x 10¹² miles/1 light years)

We cancel out the lightyears and then we are left with:

3.6 x 10² light years x 5.9 x 10¹² miles

In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.

Coefficients:

3.6 x 5.9 = 21.24

Exponents of 10:

10² x 10¹² = 10⁽²⁺¹²⁾ = 10¹⁴

Then we combine them again to form:

The least amount of interest, if Pedro has a balance of $5810 on a credit card with an APR of 16.2%, is $78.345 for one month, so option A is correct.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

Pedro has a balance of $5810 on a credit card with an APR of 16.2%,

Calculate the simple interest for one month as shown below,

[tex]SI = P \times r \times t / 100[/tex]

SI = 5810 × 16. 2 × 1 / (12 ×100)   [time in year = 1 / 12]

SI = $78.345

SI =  5810 × 16. 2 × 2 / (12 ×100)   [For 2 months]

The Equation represent the line that passes through the points  (2, -8) and (-3, 2) is 2x + y + 4 = 0

Two point form is one of the important forms used to represent a straight line algebraically. The equation of a line represents each and every point on the line, i.e., it is satisfied by each point on the line.

The two point formula is used to represent a line algebraically using the coordinates of two points that lie on that line. The formula for two point form can be given as:

(y - y1) = m(x-x1) -----------(1)

where , m is slope of line given by => y2-y1/ x2 - x1

(x, y) is an arbitrary point on the line.

(x1, y1) and (x2 , y2) are coordinates of points lying on the line.

According to the question,

The required line passes through (2,-8) and (-3,2)

Slope : m = 2 - (-8) / -3 -2

=> m = 2+8/-5

=> m = 10/-5

=> m = -2

Substituting the values in equation (1)

(y - (-8)) = -2(x-2)

1) The value of the expression x + y is; 30

2) The value of the expression m + n is; 16

1) We are told that segments LJ and A F are perpendicular. This means that; 4x + 50 = 90 and 7y - 50 = 90

Let us solve for x and y;

4x + 50 = 90

4x = 90 - 50

4x = 40

x = 10

Similarly;

7y - 50 = 90

7y = 90 + 50

7y = 140

y = 140/7

y = 20

Thus;

x + y = 10 + 20

x + y = 30

2) We are told that LJ is a perpendicular-bisector of A F. Thus;

AJ = FJ and AL = FL

Thus;

FL = AL gives;

3m = 42

m = 42/3

m = 14

Similarly;

2m + 3n = 34

2(14) + 3n = 34

28 + 3n = 34

3n = 6

Total sale on tickets at the second night = $935

Let the price of student ticket and adult ticket in school show be "$x" and "$y" respectively. According to problem,

On first night total sale,

180x + 110y = $1345 --(1)

On Second night total sale,

100x + 90y = $935 --(2)

we have to determine the price of student ticket i.e x and price of adult ticket i.e y .. We have a system of linear equation which consists two equations (1) and (2) . Now, we solve these equations using Substitution method,

From equation (2), 100x = 935 - 90y

=> x = (935 - 90y )/100 --(*)

Substitute the value of x in equation (1) 180x + 110y = $1345

=> 180(935 - 90y )/100 + 110y = 1345

Simplify ..

=> 168120 - 16200y + 11000y = 134500

=> 168120 - 134500 = 16200y - 11000y

=> 33620 = 5200y

=> y = 33620/5200

=> y = 6.46

put the value of y in equation (*) we get,

x = (935 - 90× 6.46)/100 = 3.536

Hence, the value of x is $3.536 and value of y is $6.46..
