As per the given data, Focus: (0, 16.44), Directrix: y = -16.44, Focal Diameter: 32.88, Vertex: (0, 0), and Axis of Symmetry: x = 0 (y-axis).

To determine the focus, directrix, focal diameter, vertex, and axis of symmetry for the given parabola equation, we can rewrite it in standard form, which is of the form [tex](x - h)^2[/tex] = 4p(y - k), where (h, k) represents the vertex.

16.44y = x²

Divide both sides of the equation by 16.44 to isolate y:

y = (1/16.44)x²

Comparing this equation to the standard form, we can see that h = 0 and k = 0.

Therefore, the vertex is (h, k) = (0, 0).

The general equation for a parabola in standard form is given by (x - h)^2 = 4p(y - k), where p is the distance between the vertex and the focus (or the vertex and the directrix). In this case, p can be found using the coefficient of y in the equation (1/4p = 1/16.44).

Thus, p = 16.44.

The focus is located at a distance of p units above the vertex, so the focus is (0, p) = (0, 16.44).

The directrix is located at a distance of p units below the vertex, so the directrix is the horizontal line y = -p, which gives us y = -16.44.

The focal diameter is twice the value of p, so the focal diameter is 2p = 2 * 16.44 = 32.88.

Therefore:

- The focus is (0, 16.44).

- The directrix is y = -16.44.

- The focal diameter is 32.88.

- The vertex is (0, 0).

- The axis of symmetry is the vertical line passing through the vertex, which is the y-axis (x = 0).

Thus, Focus: (0, 16.44), Directrix: y = -16.44, Focal Diameter: 32.88, Vertex: (0, 0), and Axis of Symmetry: x = 0 (y-axis).

Answer:

Number of TAILS outcomes = 100 - 58 = 42

Experimental probability of TAILS = Number of TAILS outcomes / Total number of outcomes = 42/100 = 0.42

The theoretical probability of getting HEADS or TAILS is 0.5 each, assuming the penny is fair.

The experimental probability of HEADS is 58/100 = 0.58, which is close to the theoretical probability of 0.5. This suggests that Aaron's experiment is consistent with the theoretical probability. Similarly, the experimental probability of TAILS is 0.42, which is also close to the theoretical probability of 0.5. This further supports the idea that the penny is fair.

Answer: the present age of son is 15 years, and the present age of father is 45 years.

Step-by-step explanation:

Let the age of son be 'x' and that of his father be 'y'.

So according to the question, the 1st equation that can be formed will be:

y = 3(x) ->(1)

[as father's age is 3 times the age of son]

Now after 5 years:

Age of son = (x+5)

Age of father = (y+5)

So according to the question, the 2nd equation that can be formed will be:

(y+5) = 2.5×(x+5) ->(2)

[as father is now two and half times old as his son]

Substituting the value of equation (1) in (2), we get:

(3x+5) = 2.5×(x+5)

=> 3x + 5 = 2.5x + 12.5

=> 3x - 2.5x = 12.5 - 5

=> 0.5x = 7.5

=> x = 7.5/0.5 = 15

Thus, the present age of son is 15 years.

Note : we can calculate the age of father by putting the value of x in equation (1) or (2):

y = 3(x) = 3 × 15 = 45 (putting x in equation 1)

Thus, the present age of father is 45 years.

The solutions to the circle equations in the attached figure are: (5) (x + 2)² + (y - 1)² = 20, (6) x² + y² = 9, (7) (x + 3)² + (y - 1)² = -9 and (8) (x - 4)² + (y - 3)² = -16

Equation of a Circle in the Cartesian coordinate system (x, y) is given by:

(x - h)² + (y - k)² = r²

where

(h, k) = coordinates of the center of the circle

r = radius.

The expression (x - h)² + (y - k)² represents the squared distance between any point (x, y) on the circle and the center point (h, k). By setting this expression equal to the square of the radius, r², we ensure that all points on the circle are equidistant from the center.

You can also expand the equation to get the standard form:

x² - 2hx + h² + y² - 2ky + k² = r².

Using the information above, let us solve the circle equations:

5) y² + 4x - 20 - 2y = -x²

First we need to find the coordinates (h, k) of the circle

x² + 4x + y² - 2y = 20

-2h = 4 => h = -2

-2k = -2 => k = 1

(h,k) = (-2, 1)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (-2))² + (y - (1))² = 20

(x + 2)² + (y - 1)² = 20

Therefore the solution to the circle equation is: (x + 2)² + (y - 1)² = 20 and the curve is attached.

6) -9 = -y² - x²

First we need to find the coordinates (h, k) of the circle

x² + y² = 9

-2h = 0 => h = 0

-2k = 0 => k = 0

(h, k) = (0, 0)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (0))² + (y - (0))² = 9

x² + y² = 9

Therefore the solution to the circle equation is: x² + y² = 9 and the curve is attached.

7) 9 = 2y - y² - 6x - x²

First we need to find the coordinates (h, k) of the circle

x² + 6x + y² - 2y = -9

-2h = 6 => h = -3

-2k = -2 => k = 1

(h, k) = (-3, 1)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (-3))² + (y - (1))² = -9

(x + 3)² + (y - 1)² = -9

Therefore the solution to the circle equation is: (x + 3)² + (y - 1)² = -9 and the curve is attached

8) 16 + x² + y² - 8x - 6y = 0

First we need to find the coordinates (h, k) of the circle

x² - 8x + y² - 6y = -16

-2h = -8 => h = 4

-2k = -6 => k = 3

(h,k) = (4, 3)

Rewrite the equation in a standard circle format

Recall: (x - h)² + (y - k)² = r²

(x - (4))² + (y - (3))² = -16

(x - 4)² + (y - 3)² = -16

Therefore the solution to the circle equation is: (x - 4)² + (y - 3)² = -16 and the curve is attached.

The Probability of Boris' character casting a spell is 8/15, based on the given odds in favor of 8/7.

The probability of Boris' character casting a spell, we can use the odds in favor of casting a spell. The odds in favor are given as 8/7.

Odds in favor of an event are calculated as the ratio of the number of favorable outcomes to the number of unfavorable outcomes. In this case, the favorable outcomes are the instances where Boris' character casts a spell, and the unfavorable outcomes are the instances where his character does not cast a spell.

Let's represent the probability of casting a spell as P(casting spell). We can use the formula for odds in favor to find the probability:

Odds in favor = Favorable outcomes / Unfavorable outcomes

8/7 = Favorable outcomes / Unfavorable outcomes

To solve for the probability, we need to convert the odds into a fraction. We can do this by considering the odds as a ratio of favorable outcomes to the total number of outcomes.

The odds can be written as:

8/(8+7) = Favorable outcomes / (Favorable outcomes + Unfavorable outcomes)

8/(8+7) = Favorable outcomes / Total outcomes

8/15 = Favorable outcomes / Total outcomes

Since the total outcomes represent all possible outcomes, the denominator represents the total number of outcomes, which includes both the favorable and unfavorable outcomes.

Therefore, the probability of Boris' character casting a spell is 8/15.

In summary, the probability of Boris' character casting a spell is 8/15, based on the given odds in favor of 8/7.

The sum of money is approximately Rs. 6250.

Given that the difference is Rs. 40, we must calculate the difference between compound interest and simple interest over a period of two years at an annual rate of 8%.

Assume that P represents the principal amount of money.

The formula for simple interest is: SI = (P * R * T) / 100

The formula for compound interest is: [tex]CI = P * (1 + R/100)^T^ - ^P[/tex]

Where

The difference between compound interest and simple interest is Rs. 40. Therefore:

CI - SI = Rs. 40

Substituting the formulas and values into the equation:

[tex](P * (1 + 8/100)^2 - P) - (P * 8 * 2 / 100) = 40[/tex]

Simplifying further:

[tex](P * (1.08^2) - P) - (0.16P) = 40[/tex]

[tex](P * 1.1664 - P) - 0.16P = 40[/tex]

Isosceles right triangles are the right triangles which has the two legs of same length.

For that first consider an isosceles right triangle with legs having length "a".

Then if we place the triangle with one of the vertices at origin, then since the length of the legs is "a", the other vertices will be at (a, 0) and (0, a).

If we place another triangle similarly with length of legs "b", then we have to prove that they are similar.

For them to be similar, there must exist a scale factor that maps one triangle on to the other.
