What is the slope of the line that passes through the points (1,-6) and (-2,-8) ?

we know that opposite sides are parallel, or namely that the figure is a parallelogram, meaning as well that opposite sides are equal, Check the picture below.

Answer:

i. Two angles can be vertical and supplementary.

ii. Yes, we can determine the angles.

Step-by-step explanation:

When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to \(180^{o}\).

It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is \(90^{o}\).

Yes, angles that are both vertical supplementary can be determined. They can be  90° each.

Vertical angles are opposite angles where two lines intersect. They are equal. So, angle 1 = angle 2,

A1 = A2 ...{i}

Supplementary angles are those which sum upto form 180. So, angle 1 + angle 2 = 180; i.e.

A1 + A2 = 180 ...{ii} By {i} and {ii} ,

putting i} in ii},

A1 + A1 = 180

Twice A1 = 180

A1 = \(\frac{180}{2}\)

= 90

As,

A1 = A2,

So,

A2 is also 90°

Thus, 90° is the correct answer.

Considering the expression of a line, the equation of the line that passes through the points (-9,-7) and (-11,-6) is the equation of the line is y= -1/2x -23/2.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of a line can be calculated as:

m= (y₂ - y₁)÷ (x₂ -x₁)

Substituting the value of the slope m and the value of one of the points in y=mx +b, the value of the "b" can be obtained.

Being (x₁, y₁)= (-9, -7) and (x₂, y₂)= (-11, -6), the slope m can be calculated as:

m= (-6 - (-7))÷ (-11 -(-9))

m= (-6 +7)÷ (-11 +9)

m= (1)÷ (-2)

m= -1/2

Considering point 1 and the slope m, you obtain:

-7= (-1/2)×(-9) + b

-7= 9/2 +b

-7 -9/2= b

-23/2= b

Finally, the equation of the line is y= -1/2x -23/2.

Step-by-step explanation:

slope =y2-y1/x2-x1

=1-0/4-0=1/4

Answer: slope intecept form: y = 1/4x

Step-by-step explanation: first we need to find the slope:

Since we have the coordinates (0,0) and (4,1), we can find the slope, which we find 1/4. We can double check this by seeing if the next point is found +4 to the right and up 1.

We have y = 1/4x + b right now, so we need to find the y intercept, in which case is zero because it goes through the origin.

So your final answer is y = 1/4x + 0, or y = 1/4x for short.

If Olive Construction Company won the job, there is a 0.4615 (or 46.15%) probability that Base Construction Company would not have submitted a proposal.

Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.

The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.

So, the probability that the base construction company did not bid:

\(\begin{aligned}& P(A \mid B)=\frac{P(B \mid A) P(A)}{P(B \mid A) P(A)+P\left(B \mid A^{\prime}\right) P\left(A^{\prime}\right)} \\& P\left(B^{\prime} \mid O\right)=\frac{P\left(O \mid B^{\prime}\right) P\left(B^{\prime}\right)}{P\left(O \mid B^{\prime}\right) P\left(B^{\prime}\right)+P(O \mid B) P(B)} \\& P\left(B^{\prime} \mid O\right)=\frac{(0.5)(0.3)}{(0.5)(0.3)+(0.25)(0.7)} \\& P\left(B^{\prime} \mid O\right)=\frac{0.15}{0.15+0.175} \\& P\left(B^{\prime} \mid O\right)=0.4615\end{aligned}\)

The scalar equation of the plane that contains given points and lines can be written as: (-4)(x-1) + 4(y-2) + (-10)(z-3) = 0.

What is equation of plane?

A given point p(x, y, z) that is located on the plane and a normal vector n define the equation of a plane. A plane's vector and scalar components can be used to formulate the equation for the plane.

The parametric form of line equation,

\(p = p_0 + t. \vec v\)

On comparing with the given equation in question, we can say that,

p = {x, y, z}, p₀ = {0, 6, 1,},  vec(v) = {3, -2, -2}

The scalar equation can be given by,

\([ \vec \omega, p - p_1] = 0\)

Here, p₁ = {1, 2, 3} and ω is perpendicular to v and to the segment p₁ - p₀ So,

\(\vec \omega = \vec v \times (p_1 - p_0) = ( 3, -2, -2 ) \times (1, -4, -2)\)

then,

\(\vec \omega = (-4, 4, -10)\)

Therefore, the scalar equation can be written as:

(-4)(x-1) + 4(y-2) + (-10)(z-3) = 0

It can also be written as:

Find a scalar equation of the plane that contains the point (1,2,3) and contains the line represented by the vector equation r(t) = [3t, 6 - 2t, 1 -2t] ?

The tree stump is approximately 2.64 feet tall. This is solved using the Tangent Function.

Let's assume that the height of the tree stump is h feet.

Since the roots of the tree extend out from the base of the tree the same distance that the stump is tall, the distance between the end of the roots and the top of the stump is also h feet.

Therefore, the total distance covered by the 2x4's is 2h feet (h feet up to the top of the stump and h feet down to the end of the roots).

We can use the tangent function to find the angle of incline. The tangent of an angle is equal to the opposite side divided by the adjacent side.

In this case, the opposite side is h and the adjacent side is 5 feet. So, we have:

tan θ = h/5

To maximize the angle of incline, we want to maximize the value of θ. This occurs when tan θ is as large as possible.

Since the tangent function is an increasing function, we can find the largest possible value of tan θ by finding the largest possible value of h.

Solving for h in the equation tan θ = h/5, we get:

h = 5 tan θ

Since the length of the boards is 5 feet, we know that:

2h = 5

Substituting for h, we get:

2(5 tan θ) = 5

10 tan θ = 5

tan θ = 0.5

Using a calculator or a table of tangent values, we can find that the angle whose tangent is 0.5 is approximately 26.57 degrees.

Therefore, the height of the tree stump is:

h = 5 tan θ

h = 5 tan 26.57

h ≈ 2.64 feet

So, the tree stump is approximately 2.64 feet tall.

And we want to solve this by substitution, first, we can rewrite the first equation as:

-3x + 3*(2y) = 12

Now we can substitute the second equation 2y = x + 4 in the parenthesis, we will get:

-3x + 3*(x + 4) = 12

Now we can solve this for x.

Four triangles would be formed by drawing all the diagonals from a single vertex of a hexagon.

When all the diagonals are drawn from a single vertex of a polygon, the number of triangles formed depends on the number of sides of the polygon. To calculate the number of triangles, we need to use the formula:

number of triangles = (number of sides - 2)

For example, if we have a pentagon (a polygon with five sides), the number of triangles formed from a single vertex would be:

number of triangles = (5 - 2) = 3

So, three triangles would be formed by drawing all the diagonals from a single vertex of a pentagon.

Similarly, for a hexagon (a polygon with six sides), the number of triangles formed would be:

All the sides are marked with congruency slashed, and they all line up when you orient the triangles the same way, so the statement is SSS.

In a proportional relationship between two quantities, the constant of proportionality, often denoted by the letter "k," represents the value that relates the two quantities. The equation y = kx is the standard form for expressing a proportional relationship, where "y" and "x" are the variables representing the two quantities.

Here's a breakdown of the components in the equation:

y: Represents the dependent variable, which is the quantity that depends on the other variable. It is usually the output or the variable being measured.

x: Represents the independent variable, which is the quantity that determines or influences the other variable. It is typically the input or the variable being controlled.

k: Represents the constant of proportionality. It indicates the ratio between the values of y and x. For any given value of x, multiplying it by k will give you the corresponding value of y.

The constant of proportionality, k, is specific to the particular proportional relationship being considered. It remains constant as long as the relationship between x and y remains proportional. If the relationship is linear, k also represents the slope of the line.

For example, if we have a proportional relationship between the distance traveled, y, and the time taken, x, with a constant of proportionality, k = 60 (representing 60 miles per hour), the equation would be y = 60x. This equation implies that for each unit increase in x (in hours), y (in miles) will increase by 60 units.

Step-by-step explanation:

Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

 Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

 book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

 to read after x days

∴ y = 450 - 30 x

V =\(\pi * \int[ (2 - x)^2 - (2 - \sqrt(x))^2 ] dx \ from\  x = 0\  to\  x = 1\)

To set up the integral for the volume of the solid of revolution formed by rotating the region between y = sqrt(x) and y = x around the line x = 2, we will use the washer method. The washer method formula for the volume is given by:

V = pi * ∫\([R^2(x) - r^2(x)] dx\)

where V is the volume, R(x) is the outer radius, r(x) is the inner radius, and the integral is taken over the interval where the two functions intersect. In this case, we need to find the interval of intersection first:

\(\sqrt(x) = x\\x = x^2\\x^2 - x = 0\\x(x - 1) = 0\)

So, x = 0 and x = 1 are the points of intersection. Now, we need to find R(x) and r(x) as the distances from the line x = 2 to the respective curves:

R(x) = 2 - x (distance from x = 2 to y = x)
r(x) = 2 - sqrt(x) (distance from x = 2 to y = sqrt(x))

Now, plug these into the washer method formula and integrate over the interval [0, 1]:
