The value of k for which the three points (1,8​), ​(2,11​), and​ (3,k) be on the same​ line will be on the same line is 14.

The slope is the rate of change.It can also be defined as the rise over run.

According to the given question for what value of k will the three points ​   (1,8​), ​(2,11​), and​ (3,k) be on the same​ line.

If three three points are on the same line they are co-linear and the slope of the points (1,8​), ​(2,11​) and (2,11​), (3,k) will be same.

∴ (11-8)/(2-1) = (k-11)/(3/2)

11-8 = k - 11

k = 11 + 11 - 8

k = 22 - 8

k = 14.

The solution of given system of equations are x = -1.146 and           x = 4.833

In this question, we have been given a system of equations.

4x^ 2 -3x+6=2x^ 4 -9x^ 3 +2x

We can write it as:

y = 4x² - 3x + 6

y = 2x^4 - 9x³ + 2x

We need to find the solution of given system of equations.

Consider the following graph of given system of equations as shown below.

In graph both the equations intersect at two points (-1.146, 14.687) and (4.833, 84.945)

Point of intersection gives the solution of the equations.

x-coordinate of the intersection of graph gives the solution because function depends on x.

Therefore, the solution of given system of equations are x = -1.146 and           x = 4.833

Answer:1/4 of robot

Step-by-step explanation:

We can rearrange it to the standard form perimeter a = s - b - C/2

In arithmetic, what is a perimeter?

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

The answer to your question is a = s - b - C/2

To solve for "a", we must get "a" on it's own side of the equal sign. We can first subtract "s" from both sides:

0 = a + b + C/2 - s

Then, we can subtract a from both sides:

-a = b + C/2 - s

Finally, we divide both sides by -1, so a is by itself.

a = -b - C/2 + s

And we can rearrange it to the standard form:

a = s - b - C/2

Based on the selling price of the property in 6 years, the present value of the selling price is $3,313,315.

This amount is NOT attractive.

Based on the annual cash flows from the property, the present value of the cash flows is $4,640,991.40.

The property will then be attractive

The present value of the selling price can be found as:

= Selling price / (1 + rate) ^ number of years

= 4,700,000 / (1 + 6%)⁶

= $3,313,315

This amount is less than the buying price of the property today so the property is not attractive as it would result in a present value loss.

The present value of the cashflows will be the present value of an annuity because the rent is constant:

= Rent value x Present value interest factor of an annuity, 6 years, 6%

= 270,000 x 4.91732

= $1,327,676.40

The present value of the property then becomes:

= 1,327,676.40 + 3,313,315

= $4,640,991.40

The property then becomes very attractive because the present value gives a gain over the selling price of $3.7 million.

Step-by-step explanation:

The Pascal's Triangle expansion of (3 x-1)^4 is mathematically given as

[tex]$$\begin{aligned}&1(3 x)^4(-1)^0+4(3 x)^3(-1)^1 +6(3 x)^2(-1)^2+4(3 x)^1(-1)^3 +1(3 x)^0(-1)^4\end{aligned}$$[/tex]

This is further explained below.

Generally,  the equation for the expansion is  mathematically given as

(3 x-1)^4

Pascal's Triangle can be displayed as such:

1

1-1

1-2-1

1-3-3-1

1-4-6-4-1

The triangle can be used to calculate the coefficients of the expansion of (a+b)^n by taking the exponent n and adding 1 .

The coefficients will correspond with line n+1 of the triangle.

For (3 x-1)^4, n=4 so the coefficients of the expansion will correspond with line 5.

The expansion follows the rule

(a+b)^n=c_0 a^n b^0+c_1 a^{n-1} b^1+c_{n-1} a^1 b^{n-1}+c_n a^0 b^n

The values of the coefficients, from the triangle, are $-4-6-4-1.

[tex]$1 a^4 b^0+4 a^3 b+6 a^2 b^2+4 a b^3+1 a^0 b^4$[/tex]

Substitute the actual values of a 3 x and b-1 into the expression.

The two equations that represent the remaining angle relationships are

x = 2(y + z) - 20 and x = 3z - 20

From the question, we are to determine the two equations that represent the remaining angle relationships

From the given information, we have that

x is the largest angle, y is the next largest angle and z is the smallest angle

Also, from the information,

"The measure of the largest angle is 20 degrees less than twice the sum of the measure of the other two angles"

That is,

x = 2(y + z) - 20

and

"The largest angle is 3 times the smaller angle minus 20 degrees"

x = 3z - 20

Hence, the two equations that represent the remaining angle relationships are x = 2(y + z) - 20 and x = 3z - 20
