Answer 1

Step 1: Corresponding sides, AB = 2 units, BC = √(13) units, AC = 3 units, A'B'= 4 units, B'C' = √(52) units, C'A' = 6 units. Step 2: scale factor of dilation is 2. Bonus: 2√(13) units.

Describe Dilation?

Dilation can be performed with respect to a fixed point called the center of dilation, or with respect to a fixed line called the line of dilation. When dilation is performed with respect to a point, the distance between the center of dilation and every point on the object is multiplied by the same scale factor. When dilation is performed with respect to a line, the distance between every point on the object and the line of dilation is multiplied by the same scale factor.

Step 1: Comparing corresponding sides

AB = distance between A(2,3) and B(2,1) = 2 units

BC = distance between B(2,1) and C(5,3) = √((5-2)² + (3-1)²) = √(9+4) = √(13) units

AC = distance between A(2,3) and C(5,3) = 3 units

A'B' = distance between A'(-4,-1) and B'(-4,-5) = 4 units

B'C' = distance between B'(-4,-5) and C'(2,-1) = √((-4-2)² + (-5+1)²) = √(36+16) = √(52) units

C'A' = distance between C'(2,-1) and A'(-4,-1) = 6 units

Step 2: Finding the scale factor

To find the scale factor, we need to divide the length of each corresponding side in triangle A'B'C' by the length of the corresponding side in triangle ABC. This gives us:

Scale factor = A'B' / AB = 4/2 = 2

So, the scale factor of dilation is 2.

Bonus: Finding the length of BC and B'C'

To find the length of BC and B'C', we can use the distance formula.

The length of BC = √((5-2)² + (3-1)²) = √(13) units.

The length of B'C' = √((-4-2)² + (-5+1)²) = √(52) units.

Alternatively, we could also use the scale factor to find the length of B'C':

B'C' = BC x scale factor = √(13) x 2 = 2√(13) units.

the relationship between the diameter of the pizza and its cost per square inch is non-proportional.

The relationship between the diameter of the pizza and its cost per square inch is non-proportional.

If the relationship were proportional, then the cost per square inch of the pizza would remain constant as the diameter changes. However, in this case, we see that as the diameter of the pizza increases, the cost per square inch decreases. This is because the area of a circle increases more rapidly than its diameter, so the cost must be spread out over a larger area, resulting in a lower cost per square inch.

Therefore, the relationship between the diameter of the pizza and its cost per square inch is non-proportional.

Before a renovation, a movie theater had 140 seats. After the renovation, the theater has 171 seats. What is the approximate percentage increase of the number of seats in the theater? If necessary, round to the nearest tenth of a percent.

Answers

To find the percentage increase, we need to calculate the difference between the new and old number of seats, divide that difference by the old number of seats, and then multiply by 100 to express the result as a percentage:

Difference = New number of seats - Old number of seats
Difference = 171 - 140
Difference = 31

Percentage increase = (Difference / Old number of seats) x 100
Percentage increase = (31 / 140) x 100
Percentage increase ≈ 22.1%

Therefore, the approximate percentage increase of the number of seats in the theater is 22.1%.

• The density of granite is approximately 2.75 grams per cubic centimeter.
What is the difference, to the nearest gram of the masses of the cones?

Answers

As a result, the difference is 837 grammes between the cones' respective masses.

Describe density.

Mass per unit volume is measured using density. It is described as a substance's mass per unit volume. The following is the density formula:

Mass / Volume equals density.

So, The formula m = V, where m is the mass, is the density, and V is the volume, can be used to determine each cone's mass.

The formula below can be used to determine each cone's mass:

- The mass of a steel cone weighs 1298.21 grams or 7.75 grams per cubic centimeter.

- The granite cone weighs 460.76 grams, or 2.75 grams per cubic centimeter.

- Mass of steel cone = 7.75 g/cm³ × 167.55 cm³ = 1298.21 grams

- Mass of granite cone = 2.75 g/cm³ × 167.55 cm³ = 460.76 grams

for difference of masses = 1298.2 grams - 460.76  grams = 837 grams

Answers

The length of one of the ropes is approximately 10.77 feet when rounded to the nearest foot.  

Let's call the distance between the poles "d" and the height of the poles "h". We can use the Pythagorean theorem to find the length of the ropes:

If we draw a diagram, we can see that the four ropes form the hypotenuses of four right triangles. Each right triangle has a base of d/2 and a height of h - (banner height)/2.

Therefore, we have:

[tex]x^2[/tex] = [tex](d/2)^2[/tex] + [tex](h - (banner height)/2)^2[/tex]

Substituting the given values, we get:

[tex]x^{2}[/tex] = [tex](20/2)^2[/tex]+ [tex](16 - (8/2))/2)^2[/tex]

[tex]x^{2}[/tex]= 100 + [tex](8/2)^2[/tex]

[tex]x^{2}[/tex] = 100 + 16

[tex]x^{2}[/tex] = 116

Taking the square root of both sides, we get:

x = [tex]\sqrt{116}[/tex]

x ≈ 10.77

Therefore, the length of one of the ropes is approximately 10.77 feet when rounded to the nearest foot.

Un vêtements qui coutait initialement 100€ a vu son prix diminuer de 30% une première fois puis une deuxième fois de 20%.Quel pourcentage de réduction correspond à ces deux baisses successives?

Answers

Step-by-step explanation:

La première baisse de prix est de 30%, ce qui signifie que le prix du vêtement est maintenant de 70% de son prix initial :

Prix après la première baisse = 100€ - (30% x 100€) = 70€

Ensuite, le prix est réduit à nouveau de 20%. Cela signifie que le prix final est de 80% du prix après la première baisse :

Prix après la deuxième baisse = 70€ - (20% x 70€) = 56€

Le pourcentage de réduction totale correspond donc à la différence entre le prix initial et le prix final, exprimé en pourcentage du prix initial :

Pourcentage de réduction totale = ((100€ - 56€) / 100€) x 100% = 44%

Le vêtement a donc subi une réduction de 44% au total après les deux baisses successives de prix.

196 children's tickets and 328 adult tickets were sold.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations or an equation system.

Here, we have

Given: One night a theater sold 524 movie tickets. An adult's ticket costs $6.50 and a child's ticket cost $3.50. In all, $2881 was taken in.

Let the amount of the child's ticket be x

Let the amount of adults tickets be y

If the total number of tickets sold is 524 movie tickets, then;

x + y  = 524

x = 524 - y...(1)

If an adult ticket cost $6.50 and a child’s ticket cost $3.5 with a total of $2881 in all, then;

3.5x +  6.5 y = 2881

35x + 65y = 28810 ...(2)

Substitute equation 1 into 2:

35x + 65y = 2881

35(542-y) + 65y = 28810

18970 - 35y + 65y = 28810

30y = 9840

y = 328

Put the value of y in equation (1) and we get

x = 524 - 328

x = 196

Hence,  196 children's tickets and 328 adult tickets were sold.

There are plans to install underground pipeline from the lake to the water level in Apache Durham Park what is the approximate length of pipe needed to the nearest meter

Answers

To determine the approximate length of the underground pipeline needed from the lake to the water level in Apache Durham Park, we would know the distance between the lake and park, as well as the specific path that the pipeline would take from the lake to the park.

Define the term length?

Length is a physical or conceptual measurement of the extent of something from one end to the other.

It refers to the distance between two points or the size of an object or entity in the direction of its longest dimension. In mathematics and geometry, length is a fundamental concept used to describe the size and shape of geometric figures and objects.

It is measured in units such as meters, feet, inches, or centimeters

Assuming that we have this information, we can use the distance between the two points as the approximate length of the pipeline. To calculate this distance, we can use the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) represents the coordinates of the lake and (x2, y2) represents the coordinates of Apache Durham Park.

Once we have the distance between the two points, we can round it to the nearest meter to get the approximate length of the pipeline needed.

It describes the separation of two points or the size of an item or entity measured along its longest axis. Length is a basic notion in mathematics and geometry that is used to describe the size and shape of geometric figures and objects.

Its dimensions are expressed in terms of meters, feet, inches, or millimeters.

Assuming we have this knowledge, we can use the distance between the two locations to estimate the pipeline's length. We can use the following algorithm to determine this distance:

The two shorter sides of an right triangle measure 15 inches and 3 feet. What is the length of the longest side?

Answers

The two shorter sides of a right triangle measure 15 inches and 3 feet and the length of the longest side also known as the hypotenuse is 3.269557 feet.

It is given to us that the two shorter sides of a right triangle measure 15 inches and 3 feet.

Let us say that side a is 3 feet and side b is 15 inches and we need to find side c, that is the longest side also known as the hypotenuse,

A right-angled triangle is one in which only one angle is precisely 90 degrees. Since the total of all the angles in a triangle is always 180°, the other two angles will be obviously smaller than the right angle.

We define the sides of a right-angled triangle in a unique manner. The hypotenuse of a triangle is the edge that faces the right angle and is always the largest.

Pythagorean formula. Pythagoras' theorem says that: a² + b² = c². in a right triangle with cathetus a and b and with hypotenuse c.

Take the square root of both sides to find c = √(b²+a²). This Pythagorean theorem expansion can be thought of as a "hypotenuse formula."

Therefore, with this formula we can solve for hypotenuse:

side a = 15 inches = 1.3 feet

side b = 3 feet

a² + b² = c²

1.3² + 3² = c²

1.69 + 9 = c²

10.69 = c²

c = 3.269557 feet

Therefore, we can say that the two shorter sides of a right triangle measure 15 inches and 3 feet and the length of the longest side also known as the hypotenuse is 3.269557 feet.

Answer p= 9

Step by step

Slope is -5/1 as y/x

Slope can be found with slope formula

y2 - y1 over x2 - x1

We only need to solve for y since “p” is a y value

Y2 - y1 = -5
4 - p = -5
Subtract 4 from both sides to isolate p
4 - 4 - p = -5 -4
-p = -9
p = 9

So now we have ( 7, 9) and ( 8, 4)

y2 - y1 over x2 - x1

4 - 9 over 8 - 7 = -5/1 slope

Problem solved!

The average rate of change of the function f(x) over the interval [-2, -9] is -6.

What is the average rate of change of the function f(x)?

To determine the average rate of change of the function f(x) over the interval [-2, -9], we need to find the slope of the secant line that connects the points (-2, f(-2)) and (-9, f(-9)).

We first find the values of f(-2) and f(-9):

f(-2) = (-2)² + 5(-2) + 14 = 4 - 10 + 14 = 8

f(-9) = (-9)² + 5(-9) + 14 = 81 - 45 + 14 = 50

So, the two points are (-2, 8) and (-9, 50).

The slope of the secant line between these two points is:

slope = (f(-9) - f(-2)) / (-9 - (-2)) = (50 - 8) / (-9 + 2) = 42 / -7 = -6

The length of the second arc is 8 feet.

The rope is swinging in such a way that the length of the arc is decreasing geometrically.

If the first arc is 18 feet long and the third arc is 8 feet long,

The length of the second arc :

In order to find the second arc length, we need to use the formula of the geometric sequence.

We have to understand what is given and what is required.

Given : First arc = 18 feet

Third arc = 8 feet.

To Find : Length of the second arc.

The formula of the geometric sequence is :

[tex]a_n[/tex] = [tex]a_1[/tex] × rn − 1

where, r = Common ratio [tex]a_1[/tex] = First term [tex]a_n[/tex] = [tex]n^{th}[/tex] term

Here, the length of the first arc is [tex]a_1[/tex] = 18.

The length of the third arc is [tex]a_3[/tex] = 8.

We have to find the length of the second arc, which is [tex]a_2[/tex]

Using the formula of the geometric sequence, we can find the [tex]a_1[/tex]: r= [tex]a_3[/tex] / [tex]a_2[/tex]

We know that [tex]a_1[/tex]= 18 and [tex]a_3[/tex]= 8

Substitute the values: r= 8 / [tex]a_2[/tex]

Now, we can rewrite the formula of the geometric sequence: an=[tex]a_1[/tex]×rn−1an= [tex]a_1[/tex] x r(n-1)

The length of the first arc is [tex]a_1[/tex] = 18 feet.

Substituting the value of r, we get:

8 / [tex]a_2[/tex] = r18 x r(n-1) = [tex]a_2[/tex]

We are given that the length of the third arc is 8 feet,

thus : 8 = 18 x r(3-1)8

= 18 x [tex]r_2[/tex][tex]r_2[/tex]

= 8 / 18[tex]r_2[/tex]

= 4 / 9r

= √(4/9)

Using this value of r, we can find the length of the second arc :

[tex]a_2[/tex] = 18 x (4/9) (2-1) [tex]a_2[/tex]

= 18 x (4/9)[tex]a_2[/tex]

= 8

if A shopkeeper sold a Radio at 336 rs and gain 5 persent profit find c. p​

Answers

Answer:

If the shopkeeper sold the radio for 336 rs and gained a 5% profit, then the cost price (c.p.) of the radio can be calculated as follows:

Let x be the cost price of the radio. Since the shopkeeper gained a 5% profit, we can write the equation: x + 0.05x = 336 Solving for x, we get: x(1 + 0.05) = 336 x = 336/1.05 x = 320

So, the cost price (c.p.) of the radio is 320 rs.

Answers

Based on the table provided, the statement that is true is of all the cats adopted, about 66% were adopted in a month or less.

How to calculate a percentage?

To calculate a percentage, you need to divide a part by the whole and then multiply the result by 100. The formula for calculating a percentage is:

Percentage = (Part / Whole) x 100

Alternatively, if you have the percentage and the whole, you can use the following formula to find the part:

Part = (Percentage / 100) x Whole

Based on this, let's prove the true statement:

Total of animals: 58 cats

Total of cats adopted in a month or less: 38

Percentage = 38/ 58 x 100 = 65.5% which can be rounded as 66%

Suppose that the functions q and r are defined as follows. Find the following

Answers

The value of the function q and r are as follows (q ° r )(7) = 22 and (r ° q)(7) = 8.

What are composite functions?

The process of integrating two or more functions into one function is known as composition of functions. A function is an example of labour. Take making bread as an example. Let x be the flour, let g(x) be the function that the food processor performs to prepare the dough using the flour, and let f(x) be the function that the oven does to bake the bread. The output of g(x) should be sent into the function f(x) to make bread (i.e., the prepared dough should be placed in the oven). The outcome is represented by the symbol f(g(x)), and it is made up of the functions f(x) and g. (x).

The function q and r are as follows:

q(x) = x² + 6

r(x) = √(x + 9)

The value of:

(q ° r )(x) = q(r(x))

Here, substitute the value of x in q(x) with the value of r(x):

q(r(x)) = (√(x + 9))² + 6

q(r(x)) = x + 9 + 6

Substitute x = 7:

q(r(7)) = 7 + 9 + 6 = 22

Now, (r ° q) = r(q(x))

r(q(x)) = √(x² + 6 + 9)

= √(x² + 15)

Substitute x = 7:

r(q(7)) = √(7² + 15) = √(49 + 15) = √64 = 8

Hence, the value of the function q and r are as follows (q ° r )(7) = 22 and (r ° q)(7) = 8.
