To dilate of the small triangle to get the large triangle the center of dilation is required

The description of the dilation is as follows;

Location of the center of dilation;

The coordinate of the center of dilation is given as follows;

[tex]\left( x_0 = \dfrac{k \cdot x_1 - x_2}{k - 1}, \ y_0 = \dfrac{k \cdot y_1 - y_2}{k - 1} \right)[/tex]

Where;

k = The scale factor of dilation

(x₁, y₁) = A coordinate point on the preimage

(x₂, y₂) = A coordinate point on the image

From the given drawing, we have;

Two vertices on the preimage are; (2, 0), and (5, 1)

Two corresponding vertices on the image are; (0, 0), and (9, 3)

Using the formula for length, l, we have;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

[tex]l_{small} = \sqrt{\left (1 -0 \right )^{2}+\left (5-2 \right )^{2}} = \sqrt{10}[/tex]

[tex]l_{large} = \sqrt{\left (9 -0 \right )^{2}+\left (3-0 \right )^{2}} = \sqrt{90} = 3 \cdot \sqrt{10}[/tex]

[tex]\left( x_0 = \dfrac{3 \times 2 -0}{3 - 1}, \ y_0 = \dfrac{3 \times 0 - 0}{3 - 1} \right)[/tex]

[tex]\left( x_0 = 3, \ y_0 = 0\right)[/tex]

The steps to create the larger triangle from the center of dilation are as follows;

Alternatively larger triangle can also be created using the vertices as follows;

The coordinates of the third vertex of the small triangle are; (4, -2)

To obtain the coordinates of the large triangle, the coordinates of

the small triangle are multiplied by the scale factor, followed by adding the

coordinates of the center of dilation, we have that the coordinates of the

image are;  

[tex](k \times x_{ai} + x_0, \ k \times y_{ai} + y_0)[/tex]

Where;

[tex](x_{ai}, \ y_{ai})[/tex] = The difference between the coordinate values of the vertices of

the small triangle and the center of dilation, we have;

(2 - 3, 0 - 0) = (-1, 0)

(5 - 3, 1 - 0) = (2, 1)

(4 - 3, -2 - 0) = (1, -2)

We have [tex](k \times x_{ai} + x_0, \ k \times y_{ai} + y_0)[/tex] are;

(3 ×(-1) + 3, 3× 0 + 3) = (-3 + 3, 0) = (0, 0)

(3 × 2 + 3, 3 × 1 + 0) = (6 + 3, 3) = (9, 3)

(3 × 1, 3 × (-2) + 0) = (3 + 3, -6) = (6, -6)  

The vertices of the larger triangle are found as (0, 0), (9, 3), (6, -6)

By drawing lines joining derived vertices the larger triangle can be created

Answer:

Point of Intersection = (2/3, -16/3)

Step-by-step explanation:

Equation of line AB

=> y + 18 / -15 + 18 = x + 3 / -2 + 3

=> y + 18 = 3x + 9

=> y = 3x - 9

Equation of Line CD

=> y + 13 / -7 + 13 = x + 7 / -1 + 7

=> y + 13 = x + 7

=> y = x - 6

Intersection

=> 3x - 9 = x - 6

=> 2x = 3

y = 2/3 - 6

y = -16/3

Point of Intersection = (2/3, -16/3)

Answer:

[tex]\huge\boxed{\sf 22670.80 \ cm^3}[/tex]

Step-by-step explanation:

Height = h = 20 cm

Diameter = d = 38 cm

Radius = d / 2 = 38 / 2 = 19 cm

Volume of cylinder:

[tex]= \pi r^2 h\\\\= (3.14)(19)^2(20)\\\\= (3.14)(361)(20)\\\\= 22670.80 \ cm^3\\\\\rule[225]{225}{2}[/tex]

Solution:

Given:

First, let's find the radius of the cylinder as the radius of the cylinder is included in the formula.

[tex]\text{Diameter = 2(Radius)}[/tex]

[tex]\text{Radius} = \dfrac{\text{Diameter}}{2}[/tex]

[tex]\text{Radius} = \dfrac{38}{2}[/tex]

[tex]\text{Radius} = 19 \ \text{cm}[/tex]

Recall that the volume of a cylinder is πr²h. Now, let's use the formula to find the volume of the cylinder.

[tex]\pi r^{2} h = \text{Volume of cylinder}[/tex]

[tex](\pi)( r^{2})( h) = \text{Volume of cylinder}[/tex]

Kendall need 33 more bags of popcorn to be sold.

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given that, Kendall is selling bags of popcorn to raise money for her soccer team. If she has raised $104 so far and the popcorn bags cost $8 each, she needs to raise $400, we need to find how many more must she sell in order to raise at least $400.

Let she needs to sell x more bags of popcorn,

Therefore,

140 + 8x = 400

8x = 260

x = 32.5 ≈ 33

Hence, Kendall need 33 more bags of popcorn to be sold.

Step-by-step explanation:

We know that all the interior angles of a triangle sum up to 180°.

(7x+3)°+(80°)+(55°) = 180°

(7x+3)°= 45°

7x = 42°

Answer:

Height = 108.35 cm

Step-by-step explanation:

Given :-

Radius = 26 cm

Total Volume = 230,000 cm³

To Find :-

Height

Formula Required :-

Volume (cylinder) = π x (radius)² x height

=> height = volume / π x (radius)²

Solving :-

h = 230,000 / (3.14 x 676)

h = 230,000 / 2122.64

Solution :-

Height = 108.35 cm

Answer:

okay so the is 140 degrees right and d and e are on a straight line so extend every line in that diagram so to get a it will be 180 degrees - 140 and e is equals to 40 degrees k will be 180 degrees because of angle y and d Angle c is equals to 100 degrees because it falls on a straight line with 80 degrees and angles in a straight line add up to 180° uncle g is equals to 100 degrees because it alternate angles c

The measure of angle g from the given figure is 80°.Therefore, option C is the correct answer.

A quadrilateral is a polygon with four sides four angles and four vertices. Whenever we name a quadrilateral, we need to keep in mind the order of the vertices.

Given that, angle d is 140°.

We know that, sum of interior angles of a quadrilateral is 360°.

From the given figure,

c°+80°=180°

c°=100°

Now, 40°+d°+g°+c°=360°

40°+140°+g°+100°=360°

g°+280°=360°

g°=80°

Therefore, option C is the correct answer.

Given

Tom has a goal of saving enough money to buy a new set of rims for his car.

Tom makes $7. 50 an hour take home pay at his job working 15 hours per week.

The earning of Tom in an hour = $7.5

If tom worked 15 hours in a week, then the amount earned by him in one week is;

Answer:

x = 1 and

x = 3

Step-by-step explanation:

The solution is the x for each row where the f(x) and g(x) are the same. When x is 1, f(x) and g(x) are both 0.

When x is 3, f(x) and g(x) are both 6.

A) The experimental probabilities are:

R = 0.45, B = 0.4, and Y = 0.15

From this, we can expect to get a red ball on the next draw.

B) This can happen because the experimental probabilities are bad estimations, or because the balls on the machine are not replaced.

A) The probability of getting each color will be given by the quotient of the number of balls of that color and the total number of balls.

For example, we know that 100 people buy gumballs, and 45 of them got red ones, so the experimental probability of getting a red gumball is:

R = 45/100 = 0.45

40 got a blue ball, so the probability of getting a blue ball is:

B = 40/100 = 0.4

15 got a yellow gumball, so the probability here is:

Y = 15/100 = 0.15

As you can see, the experimental probability of getting a red gumball is 3 times the probability of getting a yellow one. based on that, we can expect that the next gumball out from that machine will be red.

B) So now 10 more people go to the machine, and they get:

7 yellow, 1 red, and 2 blue gumballs.

This clearly does not follow the experimental probability we got above, why this may happen?

There are two main reasons.

First, to get a valuable experimental probability an experiment must be performed a lot of times, 100 is a ratter a small number. So the experimental probability that we got on point A may be a really bad estimation.

On another hand, there is a possibility that the gumballs in the machine are not being replaced. So initially, there is a fixed number of red, yellow, and blue balls.

This would mean that if we remove one red ball on the first try. Then for the next try, the probability of getting a red ball will be smaller (because now the machine has fewer red balls).

Then, because out of the 100 first balls most were red or blue, we can assume that most of the remaining balls on the machine are now yellow, and then the probability of getting a yellow ball is increased.
