The location of the fountain relative to the park entrance is  11 yards west and 27 yards north, the correct option is B.

The standard equation of a circle is given by

(x -h)² + (y-k)² = r²

The equation of the circular fountain is

(x + 11)² + (y – 27)² = 2.25

The center of the fountain is at ( -11,27)

The entrance is at (0,0)

The positive x axis denotes East and positive y axis denotes North

The location of the fountain is at 11 yards west and 27 yards north.

Hope this helps !

Answer:

See attachment :)

Step-by-step explanation:

The given equation is in slope-intercept form, which lists the slope and the y-intercept of the line.

Slope-intercept form is  \(y=mx+b\), where \(m\) is the slope and \(b\) is the y-intercept. The y-intercept, 2, is a point on the y-axis where the line intersects with the axis. So, we can graph the given intercept on the y-axis, (0,2).

The slope, \(m\), is \(\frac{4}{5}\). The slope is the rise of the line over the run, or \(\frac{rise}{run}\). For this equation, then, we rise 4 units and run 5.

We'll start from the y-intercept, a point we know will be on our line. From this point, move up 4 units, and right 5. A negative slope would run  to the left, but this is a positive line, so the run will go to the left. Now, we are on the point (5,6). From this point, we can repeat this \(\frac{rise}{run}\).

A few of the following points are (10,10), (14,15), and (18,20). Now, draw a line connecting these points. This line is a graph of our equation.

I've attached a photo of the graphed line.

Step-by-step explanation:

Price of 3 kg carrots = 1.80

Price of 1 kg carrots = 1.80 ÷ 3 = 0.6

Price of 2 kg carrots = 0.6 x 2 = 1.2

Remaining amount = 3.45 - 1.2 = 2.25

Price of 5 kg potatoes = 2.25

Price of 1kg potatoes = 2.25 ÷ 5 = 0.45

Now

Cost of 4 kg of carrots = 0.6 x 4 = €2.4

Cost of 2 kg of potatoes = 0.45 x 2 = €0.9

The total cost of 4kg of carrots and 2 kg of potatoes is £3.30

Total cost is the product of the cost of each unit and the number of units purchased.

As it is given that the cost of 3 kg carrot is £1.80, therefore, the cost of 1 kg of carrot can be written as,

\(\text{Cost of 1 kg carrot}=\dfrac{\text{Total cost of carrot}}{\text{Total amount of carrot}}\)

                              \(=\dfrac{\£1.80}{3}\\\\= \£0.60\)

Thus, the cost of 1 kg carrot is £0.60.

Now., as it is given that the cost of 2 kg carrot and 5 kg potatoes is £3.45, therefore, the cost of 5 kg potatoes can be written as,

\(\text{Total cost}=\text{Cost of 2 kg carrot}+\text{Cost of 5 kg potatoes}\)

\(3.45= (0.60 \times 2) + \text{Cost of 5 kg Potatoes}\\\\\text{Cost of 5 kg Potatoes} = 2.25\)

Further, the cost of each kg of potatoes can be written as,

\(\text{Cost of 1kg of potatoes}=\dfrac{\text{Cost of 5 kg Potatoes}}{\text{Total amount of potatoes}}\)

                                      \(=\dfrac{2.25}{5}\\\\=0.45\)

Thus, the cost of each kg of potatoes is £0.45.

Further,  the total cost of 4kg of carrots and 2 kg of potatoes can be written as,

\(\text{Total cost }=\text{Cost of 4kg of carrots} +\text{Cost of 2 kg of potatoes} \\\\\text{Total cost }=(4 \times 0.60)+(2\times 0.45)\\\\\text{Total cost }= 2.24+0.90=\£3.3\)

Hence, the total cost of 4kg of carrots and 2 kg of potatoes is £3.30

A correlation coefficient is consistently a number between 1 and - 1 .

The correlation coefficient is a factual measure that demonstrates the strength and heading of the straight connection between two factors. It goes from - 1 to 1, where - 1 addresses a completely bad correlation (i.e., as one variable expands, different declines), 0 addresses no correlation, and 1 addresses an entirely sure correlation (i.e., as one variable builds, the other likewise increments).

The indication of the correlation coefficient demonstrates the heading of the relationship, while the extent of the coefficient shows the strength of the relationship. A correlation coefficient of 0 shows no straight connection between the factors, while values nearer to - 1 or 1 demonstrate a more grounded direct relationship.

The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly can be calculated as follows:

Given, Principal = Rs 1200Time = 1.5 yearsInterest rate = 40% per annum, compounded quarterly

Let r be the quarterly rate of interest. Then we can convert the annual interest rate to quarterly interest rate using the following formula: \text{Annual interest rate} = (1 + \text{Quarterly rate})^4 - 1$$

Substituting the values, we get:0.40 = (1 + r)^4 - 1 Solving for r, we get:r = 0.095 or 9.5% per quarter

Now, we can use the formula for the amount of money after time t, compounded quarterly: $A = P \left( 1 + \frac{r}{4} \right)^{4t}

Substituting the values, we get:A = Rs 1200 x $\left(1 + \frac{0.095}{4} \right)^{4 \times 1.5}= Rs 1893.09

Therefore, the amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

The above expression can be evaluated as follow:

(√3x + √5)(√15x + 2√30)

Expand

√3x (√15x + 2√30) + √5(√15x + 2√30)

x•3√5 + 2•3√10x + 5√3x + 2•5√6

3x√5 + 6√10x + 5√3x + 10√6

We can not simplify further.

Therefore,

(√3x + √5)(√15x + 2√30) =

The x-value that corresponds to a z-score of 2.05 is approximately 130.75.

To find the x-value that corresponds to a given z-score, we use the formula:

x = μ + zσ

Where:

x is the corresponding value in the distribution,

μ is the mean of the distribution,

z is the z-score,

σ is the standard deviation of the distribution.

In this case, the mean (μ) is 100, the z-score (z) is 2.05, and the standard deviation (σ) is 15.

Substituting the values into the formula, we have:

x = 100 + 2.05 * 15

Calculating this, we get:

x = 100 + 30.75

x = 130.75

Answer:

Below in bold.

Step-by-step explanation:

The angle in a regular octagon =  180 - (360/8) = 135.

Using trigonometry  sin (135/2) = k/2 / EF

sin 67.5 = k / 2EF

2EF = k / sin 67.5

EF = k / 2 sin 67.5 = k/1.8478

Perimeter of octagon = 8 * k/1.8478

= 4.33k to the nearest hundredth.

Answer:

  y = -3√(x -1) +2

Step-by-step explanation:

You want the equation of the given square root function with its vertex at (1, 2) and point (2, -1) on the graph.

The parent square root function has its vertex at (0, 0). It extends upward from that vertex, and goes through the point (1, 1).

The function shown in the graph has its vertex at (1, 2), so has been translated 1 unit to the right and 2 units upward. The function extends downward from the vertex, so has been reflected vertically.

We know a function translated h units right and k units up becomes ...

  g(x) = f(x -h) +k

When it is reflected across the x-axis, it also has a multiplier (-a):

  g(x) = -a·f(x -h) +k

We can find the value of 'a' by using the given point in the translated function.

   g(x) = -a·√(x -1) +2

  -1 = -a√(2 -1) +2

  -3 = -a√1 = -a

The value of 'a' is 3.

The graph is described by the function ...

  y = -3√(x -1) +2

The statement "Quadrilaterals A and B are both squares" does not provide enough information to determine whether A and B are scale copies of one another.

To determine if two quadrilaterals are scale copies of each other, we need to compare their corresponding sides and angles. If the corresponding sides of two quadrilaterals are proportional and their corresponding angles are congruent, then they are scale copies of each other.

In this case, since both A and B are squares, we know that all of their angles are right angles (90 degrees). However, we do not have any information about the lengths of their sides. Without knowing the lengths of the sides of A and B, we cannot determine if they are scale copies of each other.

Therefore, the statement cannot be determined as true or false based on the given information.
