Answer:

Step-by-step explanation:

To find the center and radius of the circle represented by the equation:

x^2 + y^2 - 8x - 20y + 52 = 0

We can start by completing the square for both x and y terms as follows:

(x^2 - 8x) + (y^2 - 20y) + 52 = 0

(x^2 - 8x + 16) + (y^2 - 20y + 100) + 52 = 16 + 100

(x - 4)^2 + (y - 10)^2 = 64

Thus, the equation can be rewritten in the standard form of the circle as:

(x - 4)^2 + (y - 10)^2 = 8^2

Therefore, the center of the circle is (4, 10), and its radius is 8 units.

Step-by-step explanation:

x² + y² - 8x - 20y + 52 = 0

the standard circle equation is

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle, and r is the radius.

now, we need to find the squared terms in the original equation.

x² and y² are clearly from the (x - h)² and (y - k)².

and then

(x - h)² = x² - 2hx + h²

-2hx = -8x

2h = 8

h = 4

(y - k)² = y² - 2ky + k²

-2ky = -20y

2k = 20

k = 10

h² + k² = 16 + 100 = 116

116 - r² = 52

r² = 64

r = 8

so, the center is (4, 10), the radius is 8.

The correct answer to the question on parallel line is option (a), i.e: The value of x is 109°, because the labelled angles in each diagram are congruent.

Parallel lines are defined as lines that lie in the same plane, are always equidistant from each other, and therefore never intersect, and are called parallel lines. ]

A matched angle is the angle formed by the matching angle or transversal and the corresponding angle when two parallel lines intersect another line (that is, transversal). 

According to the question:

In the diagram, the angle "x" is corresponding angle to 109°, so by the property "corresponding angle axiom "of intersecting line to parallel lines

angle "x" is equal to 109°.

Step-by-step explanation:

A = age of Anthony

K = age of Kadeesha

Formulate equations based on the information given:

K = A + 1

A² + 2K = 82

Solve the simultaneous equations by substitution:

A² + 2(A + 1) = 82

A² + 2A + 2 = 82

A² + 2A - 80 = 0

(A + 10)(A - 8) = 0

A + 10 = 0 → A = -10

A - 8 = 0 → A = 8

Airplane A traveled at a faster rate. The solution has been obtained by using speed-distance-time relationship.

Speed is calculated by dividing the distance traveled by the time needed to complete the journey. Distance and speed are intimately associated but time and speed are not.

We are given that Airplane A traveled 1662 miles in six hours.

We know that Speed = Distance / Time

Using this, we get

⇒Speed = 1662 / 6

⇒Speed = 277 miles per hour

We are given for Airplane B that y = 922/3x , where x represents its rate of speed over the same six hours

So, from this we get,

⇒Speed = (922/3) / 6

⇒Speed = 922 / 18

⇒Speed = 51.22 miles per hour

Answer: There isn't an error, it's taxes

Step-by-step explanation:

Answer:

The percent error in the price can be calculated using the formula:

percent error = |(experimental value - actual value) / actual value| x 100%

In this case, the experimental value is the final price of $52 and the actual value is the initial price of $50. So we have:

percent error = |(52 - 50) / 50| x 100%

percent error = |2/50| x 100%

percent error = 4%

Therefore, the percent error in the price is 4%.

Answer:

Let's call the price of a student ticket "s" and the price of an adult ticket "a".

From the first day's sales, we know that:

3s + 1a = 38

From the second day's sales, we know that:

3s + 2a = 52

We can use these two equations to solve for "s" and "a".

First, we'll use the first equation to solve for "a":

3s + a = 38

a = 38 - 3s

Next, we'll substitute this expression for "a" into the second equation:

3s + 2(38 - 3s) = 52

Simplifying and solving for "s", we get:

3s + 76 - 6s = 52

-3s = -24

s = 8

So the price of a student ticket is $8.

We can substitute this value back into the first equation to solve for "a":

3(8) + a = 38

24 + a = 38

a = 14

So the price of an adult ticket is $14.

The value of x is 33.6( nearest tenth)

The Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

c² = a²+b²

represent the two sides of x by a and b

from the big triangle

b = √ 29² - 12²

b = √ 841 -144

b = √ 697

b = 26.4

from the small Triangle

a = √ 14²-12²

a = √ 196-144

a = √52

What is ratio ?

A ratio is a quantitative comparison of two or more quantities or values, expressed as the quotient of one divided by the other. It is usually represented in the form of a fraction, using a colon, or by the word "to". For example, if there are 6 boys and 4 girls in a class, the ratio of boys to girls can be represented as 6:4, or 6/4, or 6 to 4. Ratios are often used to compare the relative sizes or amounts of two or more things, such as ingredients in a recipe, parts in a machine, or components in a financial statement.

The rate for a ratio of the two different quantities is the number of one quantity for each unit of the other quantity. In this case, the rate is the number of puppies per litter.

Answer:

Ayanda will receive R20,160, Zipho will receive R15,120, and Palesa will receive R10,080.

Step-by-step explanation:

We can use the ratio of 4:3:2 to find the total number of parts:

4 + 3 + 2 = 9

This means that the money will be divided into 9 equal parts, and Ayanda will get 4 parts, Zipho will get 3 parts, and Palesa will get 2 parts.

To find the value of one part, we divide the total amount by 9:

45,360 / 9 = 5,040

Therefore, one part is worth R5,040.

Now we can find the amount of money each person will receive by multiplying their respective parts by the value of one part:

Ayanda: 4 parts × R5,040/part = R20,160

Zipho: 3 parts × R5,040/part = R15,120

Palesa: 2 parts × R5,040/part = R10,080

Therefore, Ayanda will receive R20,160, Zipho will receive R15,120, and Palesa will receive R10,080.

Answer:

Let's call the length of the rectangular room "L" and the width "W". We know that the area (A) of the room is 80 square feet, so:

A = L x W

We also know that the perimeter (P) of the room is 36 feet. The formula for the perimeter of a rectangle is:

P = 2L + 2W

We can use the fact that P = 36 to solve for one of the variables in terms of the other. Solving for W, we get:

W = (36 - 2L) / 2

Now we can substitute this expression for W into the formula for the area:

A = L x ((36 - 2L) / 2)

Simplifying, we get:

80 = (L x (36 - 2L)) / 2

Multiplying both sides by 2, we get:

160 = L x (36 - 2L)

Expanding the right side, we get:

160 = 36L - 2L^2

Rearranging and simplifying, we get a quadratic equation:

2L^2 - 36L + 160 = 0

We can solve this quadratic equation using the quadratic formula:

L = [36 ± sqrt(36^2 - 4(2)(160))] / (2(2))

Simplifying, we get:

L = [36 ± sqrt(576)] / 4

L = [36 ± 24] / 4

L = 15 or L = 5

Since the length cannot be smaller than the width, we can disregard the solution L = 5. Therefore, the length of the rectangular room is 15 feet, and the width can be found using the formula we derived earlier:

W = (36 - 2L) / 2 = (36 - 2(15)) / 2 = 3

So the length of the room is 15 feet and the width is 3 feet.

The analysis of the number of runners, can be presented as follows;

a. The sequence is a geometric sequence

b. r(3) = 72, which indicates that the number of runners after the third week is 72

c. r(6)/r(5) = (2/3)

d. The recursive rule for r(w) is that the number of  runners in a week is (2/3) × The number of passengers in the previous week

A sequence is an ordered list of items.

The number of passengers currently in the  running club = 243

The amount by which the  number reduces each week =  2/3 the number in the previous week.

a. Therefore, the number of passengers each week can be presented as follows;

First week = 243

Second week = (2/3)  × 243 =  162

Third week = (2/3)³ ×  243

Therefore, the number  of runners in the nth week is; an= (2/3)ⁿ × 243, which is a geometric sequence

b. The number of runners in the wth week, r(w) =  2/3)^w × 243,

Therefore; r(3)  = (2/3)³ × 243  = 72

The meaning of the value is that the number of runners in the third  week, r(3) =  72 runners

c. r(6))/(r(5)) can be obtained as follows;

r(6) = (2/3)^6 × 243

r(5) = (2/3)^5 × 243

r(6)/r(5) = ((2/3)^6 × 243)/( (2/3)^5 × 243) = (2/3)

d. The recursive formula can be obtained as follows;
