Answer: 216.67 meters/ min

Step-by-step explanation: Converting 13 km/h to meters per minute

First, we will convert 13 km to meters

So, we know 1 km = 1000 meters

Then 13 km/ h =  x

x = 1000 multiplied 13

x = 13,000 meters/ h

Now, we will convert to hours to minutes

We know 1 h = 60 min

Then 13,000 meters/ 60 min

That = 216.667 meters/ min

After approximating

Answer = 216.7 meters / min

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 distance up the building that the ladder would reach, given the ladder height and the base of the building, is 13.4 ft.

To find out how far up the building the ladder reaches, we can use the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

Assuming the height that the ladder reaches is x, the formula would be:

x ² + 4 ² = 14 ²

x ² = 14 ²  - 4 ²

x ² = 196 - 16

x = √ 180

Correlation Coefficient (r) o A model is deemed to be "excellent fit" if r is near to 1 (or -1). o The model is "not a good match" if r is close to 0. o The model has a "perfect fit" if r = 1, with all data points falling on the line. o The two variables do not have a linear connection if r = 0.

The strength of the linear link between two separate variables, x and y, is shown by correlation coefficients.

A positive relationship is shown by a linear correlation coefficient greater than zero.

Indicating a negative association is a value less than zero. The two variables x and y do not have any relationship when their values are 0, to sum up.

The correlation coefficient (r2) is a statistic that expresses how closely two variables' movements are related to one another.

To determine the linear relationship between two variables, the Pearson product-moment correlation, the most popular correlation coefficient, is used.

However, this correlation value might not necessarily be a reliable indicator of reliance in a non-linear connection.

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

1) X-Rays are dangerous because: "They have short wavelengths that can penetrate materials, and their high energy can damage matter."  (Option B)

2) From the table given, the wave that has the lowest energy is Wave 4.

The relationship between frequency and wavelength is inverse. The wavelength of the wave with the highest frequency is the shortest. One-half the wavelength equals twice the frequency. As a result, the wavelength ratio is inverse to the frequency ratio.

To summarize, waves transport energy. The quantity of energy carried by them is proportional to their frequency and amplitude. The greater the frequency, the greater the energy, and the greater the amplitude, the greater the energy.

Also, the lower the frequency, the lower the energy, and the lower the amplitude, the lower the energy. Thus, the wave with the lowest energy is Wave 4.

The proof is given below

We can start by using the definition of the trigonometric functions cosec(A), tan(A), and cot(A):

cosec(A) = 1/sin(A)

tan(A) = sin(A)/cos(A)

cot(A) = 1/tan(A) = cos(A)/sin(A)

Now, we can substitute these definitions into the equation:

cosec(A)/(tan(A) + cot(A)) = 1/sin(A) / (sin(A)/cos(A) + cos(A)/sin(A))

Simplifying the right-hand side gives us:

1/sin(A) / (sin(A)(1/cos(A) + 1/sin(A))) =

1/sin(A) / (sin(A)/sin(A)cos(A) + sin(A)) =

1/sin(A) / (1 + sin(A))

Finally,

multiplying both sides by sin(A) (which is not 0 because A is not a multiple of pi/2)

cosec(A)/(tan(A) + cot(A)) * sin(A) = 1/sin(A) / (1 + sin(A)) * sin(A) = 1 / (1 + sin(A)) * sin^2(A) = cos(A)

Therefore, cosec(A)/(tan(A) + cot(A)) = cos(A)

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.
