Answer:

The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49

Step-by-step explanation:

We need to find the length of segment TR with T(-4,5) and R(2, -1)​

The length of segment can be found using distance formula.

The distance formula is: [tex]Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Putting values and finding length

We have: [tex]x_1=-4, y_1=5, x_2=2, y_2=-1[/tex]

[tex]Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance = \sqrt{(2-(-4))^2+(-1-5)^2}\\Distance = \sqrt{(2+4)^2+(-1-5)^2}\\Distance = \sqrt{(6)^2+(-6)^2}\\Distance = \sqrt{36+36}\\Distance = \sqrt{72}\\Distance=8.49[/tex]

We found Distance = 8.49

So, The length of segment TR with T(-4,5) and R(2, -1)​ is 8.49.

The product of the given numbers is -31.5.

The given expression is 3(-10.50).

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

The product of given whole number and decimal number is as follows:

3×(-10.50)

= -31.5

Therefore, the product of the given numbers is -31.5.

Answer:

The slope of a line that is perpendicular to the x-axis ​is undefined.

Step-by-step explanation:

We know that the x-axis is a horizontal line.

Therefore, the slope of a line that is perpendicular to the x-axis ​is undefined.

For example, the slope between (1, 2) and (1, 4) is:

Using the slope formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 = [4 - 2] / [1 - 1]

                  = 2 / 0

                  = ∞

For example, let's expand out (x+3)*(2x+1). Use of the FOIL rule should get to you 2x^2 + 7x + 3.

Now imaging that you handed 2x^2 + 7x + 3 to a friend to be factored. They do not know the factorization yet.

They would see that a = 2, b = 7, c = 3.

The friend needs to find two numbers u,v such that they multiply to a*c = 2*3 = 6 and add to b = 7

Through trial and error (I recommend making a table of values), your friend would get

But as you mentioned, your friend could easily swap the order of addition and multiplication to say

----------------------

If we go with the first option, then the factor by grouping looks like this

2x^2 + 7x + 3

2x^2 + 1x + 6x + 3 ... break up 7x into 1x+6x

(2x^2+1x) + (6x+3) .... group up the terms into pairs

x(2x+1) + 3(2x+1) .... factor each grouping

(x+3)(2x+1) ..... factor out the overall GCF

---------------------

Or we could have the factor by grouping looks like this

2x^2 + 7x + 3

2x^2 + 6x + 1x + 3 ... break up 7x as 6x+1x

(2x^2+6x) + (1x+3)

2x(x+3) + 1(x+3)

(2x+1)(x+3)

(x+3)(2x+1)

We end up with the same factorization.

24+15k=

Step-by-step explanation:

First we multiply the 6 to the numbers in the parentheses, so 4x6=24, and 2x6=12, making the expression look like this: 24+12k+3k=

Then we combine like terms, which would be the number that are attached to 'k'. So that makes the expression look like this: 24+15k=

I'm not sure what else you're suppose to do to create a new expression since there's nothing on the other side of the equal sign, but that's as much as the expression will simplify.

Point (5, -10)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Slope and gradient is the same.

Answer:

Let "m" be the slope of the line passing through the point.

[tex]m = \frac{y_ 2 - y_1}{x_ 2 - x_1 } = \frac{( - 10 - 0)}{(5 - 0)} = \frac{ - 10}{5} = \boxed{- 2 }[/tex]

The  total length of a beam bridge is 168 yards. then the span between any two consecutive supports is 23 approx.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given that the total length of a beam bridge is 168 yards.

The Total number of supports on the bridge = 1 at both end + 3 additional = (1 + 3 + 1) = 5 supports

Arch lies in between two successive supports ;

Hence, the number of archs = 5

Hence, width of arch = (5 * x) = 5x meters

Width of support = 2 meters

The Total width of support : (2 * x+ 1) = 2(x + 1) meters

Hence,  the total distance of bridge :

Total arch width + total support width

5x  + 2(x + 1) = 168 meters

5x + 2x + 2 = 168

7x = 166

x = 23 approx

Hence, the span between any two consecutive supports is 23 approx.
