Step-by-step explanation:

First add like terms, so -5r and 8r. For a second lets pretend the r doesn't exist. So, what is -5 + 8, 3, so 3r. Since 3r and 5 cannot be combined, the equivalent expression is 3r+5.

a) The equation of  perpendicular line is y=2x+1

b) The equation of  parallel  line is y = -2x+6

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

a) An equation perpendicular to y= (-1/2)x+4 through the point (-2, -3):

m= -1/2

Slope of perpendicular line is -1/m  = -1/( -1/2) = 2

(x,y) = (-2, -3)

Slope intercept form:

y=mx+b

Substitute x,y and m values to find b

-3= 2(-2) + b

=> -3 = -4 + b

=> b= -3+4 = 1

So the equation of  perpendicular line is y=2x+1

b)  An equation through the point  (1,4)  parallel to  y = -2x + 1

Parallel lines will have same slope , m= -2

(x,y) =  (1,4)

Slope intercept form:

y=mx+b

Substitute x,y and m values to find b

4=-2(1)+b

=> 4 = -2 + b

=> b=4+2 = 6

So the equation of  parallel  line is y = -2x+6

Factor the shape

= 10⁷ (9,72 × 10 + 1,93)

In mathematical terms, each point (x, y) on Shape A is mapped to a point (2 + (2 - x), y) on Shape B as reflected line equation and explained as

When a shape is reflected in a line, it means that each point on the original shape is mapped to a corresponding point on the reflected shape that is symmetrical with respect to the reflecting line.

The line of reflection can be any straight line, and in this case, the line of reflection is given by the equation x = 2. To understand how the reflection works, imagine holding a mirror along the line x = 2 and placing Shape A on the mirror. The reflected shape, Shape B, would be the image that you see in the mirror. In mathematical terms, each point (x, y) on Shape A is mapped to a point (2 + (2 - x), y) on Shape B. This means that for each point on Shape A, we take its x-coordinate, subtract it from 2 to find the distance from the line of reflection, and then add that distance to 2 to find the x-coordinate of the corresponding point on Shape B. The y-coordinate remains the same.

The line of reflection acts as a dividing line between Shape A and Shape B, and the points on Shape B are exactly the same distance from the line of reflection as the points on Shape A, but on the opposite side. This means that Shape B is a perfect mirror image of Shape A, reflected across the line x = 2.

In summary, the reflection of Shape A in the line x = 2 maps each point on Shape A to a corresponding point on Shape B that is symmetrical with respect to the line of reflection. The result is a perfect mirror image of the original shape, reflected across the line.

The boat travels a distance of [tex](1/2k) ln(61/42)^2[/tex] in the first 2 minutes after its motor quits.

We can solve this problem using separation of variables. The differential equation that models the velocity of the boat is:

[tex]dv/dt = -kv^2[/tex]

To do this, we first need to separate the variables and integrate both sides:

[tex]1/v^2 dv = -k dt[/tex]

Integrating both sides, we get:

-1/v = kt + C

where C is the constant of integration. To find C, we can use the initial condition that the boat is moving at 83 ft/s when the motor quits:

-1/83 = k(1) + C

C = -1/83 + k

Now we can substitute C back into our equation:

-1/v = kt - 1/83 + k

Solving for v, we get:

v = 1 / (k(t - 1/83 + 1))

Now we can integrate v over the time interval [1, 121] to find the distance traveled by the boat:

d = ∫[1,121] v dt

Substituting v into the integral, we get:

d = ∫[1,121] 1 / (k(t - 1/83 + 1)) dt

We can simplify the integral by using the substitution u = t - 1/83 + 1:

d = ∫[84/83, 122/83] 1 / (ku) du

Now we can integrate this expression to get:

d = ln(u) / k |[84/83, 122/83]

d = ln(122/83) / k - ln(84/83) / k

d = (1/k) ln(122/83) - (1/k) ln(84/83)

We can simplify this expression using the fact that C = -1/83 + k:

d = (1/k) ln(122/83 / 84/83)

d = (1/k) ln(61/42)

Finally, we can plug in the initial condition k > 0 to get the distance traveled by the boat:

d = [tex](1/k) ln(61/42) = (1/2k) ln(61/42)^2[/tex]

d = [tex](1/2k) ln(61/42)^2[/tex]

Since we are not given the value of k, we cannot compute the exact numerical value of the distance traveled.

There are infinitely many possible locations for your house that would allow you to travel one mile south, one mile east, and one mile north and end up back at your starting point.

As per the question given,  

This is a classic puzzle known as the "One-Mile Puzzle". There are actually infinitely many possible locations for your house that satisfy these conditions.

One way to think about it is to consider the fact that the one-mile distances you traveled form the sides of a triangle. Since you traveled one mile due south, one mile due east, and one mile due north, the triangle you formed is an isosceles right triangle, with the right angle at the point where you ended up.

If you let (x, y) be the coordinates of your house, then the point where you ended up after traveling one mile south, one mile east, and one mile north is (x, y-1) + (1, y) + (x, y+1), which simplifies to (2x+1, 2y).

So, any point (x, y) that satisfies the equation 2x + 1 = 2y will work as a possible location for your house. For example:

If x = 0, then y = 1/2, so your house could be located at (0, 1/2).

If x = 1, then y = 3/2, so your house could be located at (1, 3/2).

If x = -1, then y = -1/2, so your house could be located at (-1, -1/2).

Directrix, y = 1

Since the directrix is a horizontal line, the parabola opens downward or upward.

The focus is located 4 units to the right of the vertex

So, we have

Vertex = (0, -3).

The equation is of the form:

(x - h)^2 = 4p(y - k),

where (h, k) is the vertex, and p is the distance from the vertex to the focus (and to the directrix).

In this case, h = 0, k = -3, and p = 2.

Answer: Let the width of the rectangle be w and the length be l. We are given that the area of the rectangle is 45 cm^2, so we can write the equation:

w * l = 45

To find the lengths of the sides, we need to solve for w and l. We can divide both sides of the equation by any non-zero number to find an equivalent expression. For example, we can divide both sides by 9:

(w/9) * (l/9) = 45/9

Simplifying, we get:

w/9 * l/9 = 5

So, w/9 = 5/l and w = 5l/9.

Substituting the expression for w into the original equation, we get:

(5l/9) * l = 45

Expanding and simplifying, we get:

5l^2/9 = 45

Multiplying both sides by 9, we get:

5l^2 = 405

Dividing both sides by 5, we get:

l^2 = 81

Taking the square root of both sides, we get:

l = 9

So, the length of the rectangle is 9 cm. To find the width, we can substitute the value of l back into the expression we derived earlier:

w = 5l/9

w = 5 * 9 / 9

w = 5

So, the width of the rectangle is 5 cm.

The lengths of the sides of the rectangle, both exactly and approximately, are 9 cm and 5 cm.
