On solving the provided question we can say that value equation is y = mx => -7 = m * 4 => m = -7/4 and x² + y² = 13 => x² + (-7)² = 13 => x

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence.

Squaring both sides and simplifying we get:

3m² + 56m + 36 = 0

The coordinates of the points A and B are (-12,103) and (-3,-89) respectively.

y = mx => -7 = m * 4 => m = -7/4

x² + y² = 13 => x² + (-7)² = 13 => x

So the equation of the tangent line is y = m(x - 0) + 0, where m = -(x+4)/(y-7)

Now we can substitute the coordinates of the center of the circle into the equation of the tangent line to get y = -(x+4)/(y-7) * x

Squaring both sides and simplifying we get:

3m² + 56m + 36 = 0

b) To find the coordinates of the points A and B, we can use the equation of the tangent line and the equation of the circle.

We know that the equation of the tangent line is y = -(x+4)/(y-7) * x and the equation of the circle is (x+4)² + (y-7)² = 13.

We can substitute y = -(x+4)/(y-7) * x into the equation of the circle and solve for x.

This equation simplifies to 3x² + 56x + 36 = 0, which factors to (x+12)(x+3) = 0

y = -(-12+4)/(y-7) * -12 = 8/(y-7) * 12 = 96/(y-7)

y = 96 + 7 = 103 and y = -96 + 7 = -89

The coordinates of the points A and B are (-12,103) and (-3,-89) respectively.

We know that the equation of the tangent line is y = mx and the equation of the circle is x² + y² = 13.

We can substitute the point (4, -7) for x and y in the equation of the tangent line and the equation of the circle and solve for m and x,y respectively.

y = mx => -7 = m * 4 => m = -7/4

x² + y² = 13 => x² + (-7)² = 13 => x

A fixed point in the plane around which all points are enlarged or contracted is the centre of a dilation. The centre, which may be found within, outside, or on a figure, is the only invariant (not changing) point under a dilation (k 1).

A Dilation of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.

The scale factor determines how much the dilated image is enlarged or reduced in size in relation to the original. A positive scale factor is required. When the scale factor exceeds 1, the dilation becomes an expansion. If it falls within the range of 0 and 1, the dilation is a contraction.

The point from which the image is dilated is known as the centre of dilatation (or point of dilation).

Following are some shape characteristics that aren't altered by the dilation transformations:

Horizontal Dilation

The dilation transformation of a function y=f(x) is dilated horizontally by a scale factor C is

Y = f(Cx)

This kind of transformation is called a horizontal dilation.

Vertical Dilation

The dilation transformation of a function y=f(x) is dilated vertically by a scale factor C isY = C * f(x)

This kind of transformation is called a Vertical dilation.

The ratio of matching side lengths is the scale factor of a dilatation. The origin will always be the centre of dilatation in this course. You can enlarge a polygon by connecting its vertices while multiplying each vertex's coordinates by the scale factor k.

Answer:

1) The standard form of a circle's equation is (x - h)² + (y - k)² = r². (h,k) is the center and r is the radius.

2) The vertex is the midpoint of the directrix and the focus. It involves the parabola changing directions, and at any point the directrix and the focus will be equidistant from the parabola. The focus is a single point inside the curve of the parabola, and the directrix is a line outside the parabola.

3) The standard form of an equation of an ellipse is:

(x − h)2a 2 +( y − k) 2 b 2 = 1 ( x − h ) 2 a 2 + ( y − k ) 2 b 2 = 1. (h,k) is the center, a is the distance from the center to the horizontal vertices and b is the distance from the center to the vertical vertices.

4) The foci are (−c,0) and (c,0). The ellipse is the set of all points (x,y) which are the sum of the distances from (x,y) to the foci is constant.  (a,0) is a vertex of the ellipse. Finally, the endpoints of the minor axis is a co-vertex of the ellipse.

5) A hyperbola has two standard equations. These equations of a hyperbola are based on its transverse axis and conjugate axis. The standard equation of the hyperbola is [(x² / a²) – (y² / b²)] = 1, where the X-axis is the transverse axis and the Y-axis is the conjugate axis.

6) The foci are located on the line that where the transverse axis is. The conjugate axis is perpendicular to the transverse axis and has the co-vertices as its endpoints. The center of a hyperbola is the midpoint of both the transverse and conjugate axes, where they intersect.

The total amount of the jet ski worth after 7/4 years is given by the equation A = $ 4,784

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the total amount of the jet ski after 7/4 years be A

Now , the equation will be

Let the number of years be x

The The value of that jet ski depreciates by function f ( x ) = 8,500 ( 0.72 )ˣ

So , the equation is f ( x ) = 8,500 ( 0.72 )ˣ

Now , when x = 7/4 years

Substitute the value of x in the equation , we get

f ( 7/4 ) = 8,500 ( 0.72 ) ^ ( 7/4 )

f ( 7/4 ) = 8,500 ( 0.72 ) ^ ( 1.75 )

f ( 7/4 ) = 8,500 x 0.5627712059

f ( 7/4 ) = $ 4,783.555

a) Tunnel A is a circle with center (-14, 0) and radius 12, meaning that both the width and the height are of 12.

b) Tunnel B is a parabola that has a width of 32 feet and a height of 16 feet.

c) The maximum height of Tunnel A is of 12 feet and of Tunnel B is of 16 feet, hence, since the height of the truck is of 13.5 feet, it can pass through Tunnel B without damage, as it's height is greater than 13.5 feet.

The equation of a circle of center  and radius r is given by:

(x-x₀) +(y-y₀) = r²

For Tunnel A, the equation is given by:

x² + y² + 28x + 52 = 0

Completing the squares:

(x + 14)² + y² = -52 + 14²

(x + 14)² + y² = 144.

Tunnel A is a circle with center (-14, 0) and radius 12, meaning that both the width and the height are of 12.

A quadratic equation is modeled by:

y = ax^2 + bx + c

For Tunnel B, the equation is given as follows:

x² - 36x + 16y + 68 = 0.

16y = -x² + 36x - 68.

Simplifying by 16:

y = -0.0625x² + 2.25x - 4.25.

Hence the coefficients are a = -0.0625, b = 2.25, c = -4.25, and the maximum height is:

y₀=(2.25)²-49-0.0625)(-1.25)/4(-0.0625) = 16

The width is the difference between the roots, which, using a calculator, are: 2 and 34, hence the width is of 32 feet.

This implies that the tunnel B is a parabola that has a width of 32 feet and a height of 16 feet.

For item c, we have that:

The maximum height of Tunnel A is of 12 feet and of Tunnel B is of 16 feet, hence, since the height of the truck is of 13.5 feet, it can pass through Tunnel B without damage, as it's height is greater than 13.5 feet.

The Probability of P(at least 3 tails) is 0.3125.

The correct option is (D).

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total outcome= 16

Now, P( less than 3 tails)= 11 /16

So, P(at least 3 tails) = P( x ≥ 3)
