The standard equation of the circle with center (-5,12) that passes through the point (-9,15) is (x + 5 )² + (y - 12)² = 25.

The standard form equation of a circle with center (h, k) and radius r is:

(x - h)² + (y - k)² = r²

Given that; the center is (-5, 12) and a point on the circle is (-9, 15).

First, we determine the radius, we can use the distance formula between the center and the point on the circle:

[tex]r = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2} \\\\r = \sqrt{(-9 - (-5))^2+(15 - 12)^2} \\\\r = \sqrt{(-9 + 5)^2+(15 - 12)^2} \\\\r = \sqrt{(-4)^2+(3)^2} \\\\r = \sqrt{16+9} \\\\r = \sqrt{25} \\\\r = 5[/tex]

Now, center: (-5, 12)

h = -5

k = 12

and r = 5

Plug these into the equation above:

(x - h)² + (y - k)² = r²

(x - (-5) )² + (y - 12)² = 5²

Simplify

(x + 5 )² + (y - 12)² = 25

Therefore, the equation of the circle is (x + 5 )² + (y - 12)² = 25.

Answer:

C(x) = 2x^3 + 2x^2 - 18x - 11

Step-by-step explanation:

Step 1: To model the water used by the car wash on a shorter day, we can subtract the amount of water saved from the original water usage function.

Step 2: Therefore, we can define the new function C(x) as: C(x) = W(x) - D(x)

Step 3: Substituting the given functions for W(x) and D(x), we get: C(x) = (3x^3 + 4x^2 - 18x + 4) - (x^3 + 2x^2 + 15)

3x^3 + 4x^2 - 18x + 4 -x^3 - 2x^3 - 15

Step 4: Simplifying by combining like terms, we get:

C(x) = 2x^3 + 2x^2 - 18x - 11

Step 5: Therefore, the function C(x) that models the water used by the car wash on a shorter day is: C(x) = 2x^3 + 2x^2 - 18x - 11

The best prediction possible for the number of times you will roll a six when rolling a six-sided die six times is one.

The best prediction possible for the number of times you will roll a six in a six-sided die depends on the probability of getting a six in each roll. The probability of getting a six in a single roll of a six-sided die is 1/6 or 16.67%.
Since the rolls are independent events, the probability of rolling a six in any one of the six rolls is still 1/6 or 16.67%. Therefore, the best prediction possible for the number of times you will roll a six is one.
However, it is important to note that probability is not a guarantee, and it is possible to roll a six more than once or not at all. But based on the laws of probability, one is the most likely outcome for the number of times you will roll a six in six rolls of a six-sided die.
In summary, the best prediction possible for the number of times you will roll a six when rolling a six-sided die six times is one.

Answer:

8.01 ft/sec

Step-by-step explanation:

Distance = 26.2 miles

Time is taken to run the distance = 4.8hrs

Average speed = ??

Average speed = distance/time

= 26.2miles /4.8hr

= 5.46 miles/hr

Convert 5.46 miles/hr to ft/sec

1 mile = 5280 ft

We have 5.46*5280 = 28828.8 ft/hr

28828.8/3600 = 8.01 ft/sec

If there are 220 pieces of 20 cents, then there are 380 pieces of 50 cents in the container.

Thabang conserves money by depositing coins in a money box. There are 600 coins in the money box, including 20- and 50-cent pieces.

We proceed as follows to determine how many 50 cent pieces are in the container if there are 220 pieces of 20 cent.

Assume that,

x = number of 20 cents

y = number of 50 cents

So, the total number of cents in the container is 600,so

x + y = 600

Making y the formula's subject, we therefore get that

y = 600 - x

Since x = 220

y = 600 - 220

y= 380

So, there are 380 fifty cents.

Note that he probability that one of the eggs selected at random was at least 19.75 mm long but less than 22.75 mm long  is 0.6%

The percent of eggs total 100.

Based on the frequency, we now that the eggs that are at least 19.75 mm include:

18.75 - 19.75 = 0.8

those that are less than 22.75mm long are:

19.75-20.75 = 4.0

20.75 - 21.75 = 17.3
21.75 - 22.75 = 37.9

Thus, the total of their frequencies are:

0.8 + 4.0 + 17.3 + 37.9  = those that are less than 22.75mm long but at least 19.75 long.

The area of the given parallelogram is 12 yd².

Given that a parallelogram of base 2 yds and height 6 yds,

We need to find the area of the parallelogram,

A parallelogram is a quadrilateral in which the opposite sides are parallel and equal. Parallelograms are classified into three main types: square, rectangle, and rhombus, and each of them has its own unique properties.

A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.

So, the area of a parallelogram = base × height

The surface area of four boxes is 4032cm².

To calculate the surface area of one box, we need to find the area of each of its six faces and then add them up.

The top and bottom faces are both squares with sides of 12cm, so each has an area of 12cm x 12cm = 144cm².

The front and back faces are both rectangles with dimensions of 12cm x 15cm,

So each has an area of 12cm x 15cm = 180cm².

The two side faces are also rectangles with dimensions of 12cm x 15cm, so each has an area of 12cm x 15cm = 180cm².
Adding up the areas of all six faces, we get:
144cm² + 144cm² + 180cm² + 180cm² + 180cm² + 180cm² = 1008cm²
Therefore, the surface area of one box is 1008cm².
To find the surface area of four boxes, we just need to multiply the surface area of one box by 4:
The surface areas of all the faces together:

(144 x 2) + (180 x 2) + (180 x 2) = 504 sq.cm

The surface area of one box is 504 square centimeters.

Since you want the surface area of four boxes, simply multiply this number by 4:

504 sq.cm x 4 = 2016 sq.cm
1008cm² x 4 = 4032cm²

It is found that x = -1/3 is the point of inflection again for function f(x) = 3x⁴ + 2x³ - 5x - 12.

Since the second variation of the function f(x) = 3x⁴ + 2x³ - 5x - 12 and then solving for the values of x where the second derivative equals zero

f'(x) = 12x³ + 6x² - 5

f''(x) = 36x² + 12x

We should discover the solutions to the equation f"(x) = 0 for x to determine the locations of inflection:

36x² + 12x = 0

12x(3x + 1) = 0

If x = 0 or x = -1/3, the equation is true.

Here F"(x) > 0 demonstrates that the graph of f(x) is concave if x 1/3.

Concavity in the curve of f(x) at -1/3 x 0 shows that f"(x) 0.

When x is greater than zero, then f"(x) is greater than zero, showing that f(x graph) is concave up.

When x = 0, the graph's concavity does not change, making x = 0 not an inflection point =only x = -1/3

6E6 is a number written in scientific notation, which means that it represents 6 times 10 raised to the power of 6. To write this number in standard form, we need to evaluate the exponent and write the number in expanded form.

6E6 = 6 x 10^6

Evaluating the exponent 6 means multiplying 6 by 10 six times:

6 x 10^6 = 6 x 10 x 10 x 10 x 10 x 10 x 10

Simplifying the expression, we get:

6 x 10^6 = 6,000,000

Step-by-step explanation:

Tshego's budget is more than R7200, then it would be enough to finish the tiling project. If his Budget is less than R7200, then it would not be enough.

We are not provided with any information in the question, so we cannot answer it as is. However, we can use the formula provided to calculate the total floor area to be tiled:

Area of a rectangle = length x width

Let's say the length is L and the width is W. Then, the total floor area to be tiled is:

Total floor area = L x W

We are not given the values of L and W, so we cannot calculate the exact total floor area. However, we can assume that Tshego has already calculated the total floor area to be 32 m².

To determine how many boxes of tiles Tshego will need, we need to know the size of each box of tiles and the total area that one box can cover. Let's assume that each box of tiles covers an area of 1 m².

If the total floor area to be tiled is 32 m², and an extra 10% of the number of tiles must be added for cutting and breakages, then the total area to be covered with tiles would be:

Total area to be covered = 32 m² x 1.1 = 35.2 m²

Therefore, Tshego would need 36 boxes of tiles to cover the entire floor area.

To determine if Tshego's budget is enough to finish the tiling project, we need to know the cost of each box of tiles and the total cost of the project. Let's assume that each box of tiles costs R200.

The total cost of the project would be:

Total cost = Number of boxes x Cost per box

Total cost = 36 x R200 = R7200

If Tshego's budget is more than R7200, then it would be enough to finish the tiling project. If his budget is less than R7200, then it would not be enough.
