The radial distances from the center (-3, -2), to the points on the circumference (0, -6), and (a, 0), found using the distance formula, indicates that a = -3 ± √21

The distance between points (x₁, y₁), and (x₂, y₂), on the coordinate plane, can be found using the formula; d = √((x₂ - x₁)² + (y₂ - y₁)²).

The coordinates of the center of the circle = (-3, -2)

The coordinates of the locations (on the circumference of the circle), through which the circle passes = (0, -6) and (a, 0)

Therefore the distances between points (0, -6) and (-3, -2) and (a, 0) and (-3, -2) are the same;

The distance from (0, -6) to (-3, -2) = The distance from (a, 0) to (-3, -2)

(-3 - 0)² + (-2 - (-6))² = (-3 - a)² + (-2 - 0)²

25 = a² + 6·a + 9 + 4 = a² + 6·a + 13

a² + 6·a + 13 = 25 (symmetric property)

a² + 6·a + 13 - 25 = 0

a² + 6·a - 12 = 0

a = (-6 ± √(6² - 4×1×(-12)))/(2×1) = (-6 ± √(84))/2

a = (-3 ± √(21))

a ≈ 1.58 and a ≈ -7.58

This does not make sense as x is a discrete variable, so it cannot take on a value of 3.5.

A binomial variable is a discrete variable, meaning it can only take on certain values. In this case, x can take on values from 0 to 10 (inclusive). Since 3.5 is not one of these values, it does not make sense to calculate the probability that x equals 3.5.

The positive value of the parameter t corresponding to a point on the parametric curve x = t^2 + 7, y = t^2 + t for which the tangent line passes through the origin is t = 7 + √56.

Given the parametric curve {x = t^2 + 7, y = t^2 + t}, we want to find the positive value of t corresponding to a point on the curve for which the tangent line passes through the origin (0, 0).

First, we find the derivative of the x and y equations to obtain the slope of the tangent line at the point (t^2 + 7, t^2 + t). The derivative of x = t^2 + 7 is

dx/ dt = 2t

and the derivative of y = t^2 + t is

dy/dt = 2t + 1

So, the slope of the tangent line at the point (t^2 + 7, t^2 + t) is

dy/dx = (dy/dt) / (dx/dt)

dy/dx = (2t + 1)/ 2t

dy/dx = 1 + 1/(2t)

Next, we use the fact that the slope of the tangent line is equal to the ratio of the change in y to the change in x between the point and the origin (0, 0). Since the origin is located at x = 0 and y = 0, we have:

(t^2 + t - 0) / (t^2 + 7 - 0) = 2t + 1)/ (2t)

2t(t^2 + t) = (2t + 1) (t^2 + 7)

2t^3 + 2t^2 = 2t^3 + t^2 + 14t + 7

t^2 - 14t = 7

t^2 - 14t + 49 = 7 + 49

(t - 7)^2 = 56

t - 7 = ±√56

t = 7 ± √56

As we require only positive value t = 7 + √56

Answer:

Let's call the radius of the cylinder and cone "r".

The surface area of the cylinder is: 2πr(r + h) = 2πr^2 + 2πrh

The surface area of the cone is: πr(l + r) = πrl + πr^2

The total surface area of the solid object is the sum of the surface area of the cylinder and the cone: 2πr^2 + 2πrh + πrl + πr^2 = (2π + π)r^2 + 2πrh + πrl

We are given that the total cost of painting the solid object is Rs. 2851.20 and the rate of painting is Rs. 140 per 100 sq cm.

So the total surface area of the solid object is: 2851200/140 = 20580 sq cm

Now we can substitute the values we know into the equation for the total surface area: 20580 = (2π + π)r^2 + 2πrh + πrl

We also know that the height of the cylinder is 28 cm and the slant height of the cone is 17 cm.

We can use the Pythagorean theorem to find the height of the cone: h^2 + r^2 = (l/2)^2

Solving this equation for h, we get: h = √(l^2/4 - r^2)

Now we can substitute the given values and solve for the height of the cone:

h = √(17^2/4 - r^2) = √(289/4 - r^2)

We don't have any information about the radius of the cylinder and cone, so we cannot solve for h in terms of r, but we can find the height of the cone by assuming the value of radius.

Let's assume the radius of the cylinder and cone is 5cm.

h = √(289/4 - 5^2) = √(289/4 - 25) = √(289/4 - 25) = √(64) = 8cm

So, the height of the cone is 8cm.

Please note that this is a theoretical height as it is based on the assumption of radius being 5cm, the actual height of the cone may be different if the radius is different.

In (a) and (d), the -1 is a reciprocal, as -1 is being multiplied by f(p) or f(p⁻¹) respectively, and the solutions for p are p = 2 and p = -7/3 respectively. In (b) and (c), the -1 is an inverse, as it is part of the inverse of f(p), and the solutions for p are p = 7 and p = 5/3 respectively.

(a) f(p) = 5 is not an inverse or a reciprocal. To solve for p, we can use the equation f(p) = 5 and solve for p. We do this by subtracting 2 from both sides of the equation to get 3p = 3, and then dividing both sides by 3 to get p = 1.

(b) f⁻¹(p) = 5 is an inverse and we can solve for p using the equation f⁻¹(p) = 5. To do this, we subtract 2 from both sides to get 3p = 3, and then divide both sides by 3 to get p = 1.

(c) (f(p))⁻¹ = 5 is a reciprocal and we can solve for p using the equation (f(p))⁻¹ = 5. To do this, we first divide both sides of the equation by 5 to get 1/f(p) = 1. Then, we multiply both sides by f(p) to get f(p) = 5. Finally, we subtract 2 from both sides to get 3p = 3, and then divide both sides by 3 to get p = 1.

(d) f (p⁻¹) = 5 is not an inverse or a reciprocal. To solve for p, we can use the equation f (p⁻¹) = 5 and solve for p. We do this by multiplying both sides of the equation by p⁻¹ to get f(p) = 5p⁻¹. Then, we subtract 2 from both sides to get 3p = 5p⁻¹ - 2, and then multiply both sides by 3 to get 9p = 5p⁻¹ - 6.

A direction field for this system of linear differential equations can be drawn by plotting the values of x' for various values of x.  As t → ∞, the solutions approach either the equilibrium point (1,0) or (3,0).

a) A direction field for this system of linear differential equations can be drawn by plotting the values of x' for various values of x, and then using arrows to indicate the direction of the solution curves at each point.

In general, the solution curves will approach the equilibrium points, which are points where x' = 0. In this case, there are two equilibrium points: (1,0) and (3,0). The solutions that start near the equilibrium point (1,0) will approach it as t → ∞, and the solutions that start near the equilibrium point (3,0) will approach it as t → ∞.

b) As t → ∞, the solutions approach either the equilibrium point (1,0) or (3,0), and thus they settle down to a constant value.

OP = 59m/s represents the plane that has a bearing of 214 degrees.

PW = 21m/s represents the wind that is blowing at an angle of N14W.

OW =  represents the resultant vector.

The angle that OP makes with west direction = 270-214=56 degrees. Therefore the angle that OP makes with the vertical is 90-56=44 degrees

In the ΔOPW,  ∠WPO = 14+44=58 degrees.

Using law of cosines, we can find the magnitude of OW

      Using law of sines we can calculate ∠WOP

  21/Sin∠WOP = 48.27/sin58

Therefore sin∠WOP = 21.SIN58/48.27  = = 0.368895

The cosine formula to find the side of the triangle is given by:

c = √[a² + b² – 2ab cos C] Where a,b and c are the sides of the triangle.

Given:

m∠B = 62°, a = 11, and c = 19

Now, b² = a² + c² - 2ac cos B.

b = √ a² + c² - 2ac cos B

b = √ 11² + 19² - 2x 11  x 19 cos 62

b= 16.9

Now. a/ sin A = b/ sin B= c/ sin C

So, <C = arc sin ( c sin B /b)

<C = arc sin ( 19 sin 62 /16.9)

In this case, the number of wheels per vehicle is 4 since both autos and motorcycles have 4 wheels each. This formula can be expressed as: Wheels = Vehicles × Wheels per Vehicle.

We can substitute the given values of the total number of wheels (336) and the number of wheels per vehicle (4) into the formula, and solve for the number of vehicles (V): Wheels = Vehicles × Wheels per Vehicle → 336 = Vehicles × 4 → Vehicles = 336 ÷ 4 → Vehicles = 84.

Since we know that both autos and motorcycles were repaired, and the total number of vehicles was 84, we can use the information that 120 vehicles were repaired to solve for the number of motorcycles (M) that were repaired.

If the total number of vehicles was 84, and 120 vehicles were repaired, then the number of motorcycles that were repaired must be equal to the difference between the total number of vehicles and the total number of autos, which is 120 - 84 = 36.

Therefore, 36 motorcycles were repaired during the month.
