The co-ordinate of B ( -3 , 2 )

Its x value lies in the middle of the two x values.

Its y value lies in the middle of the two y values.

To figure it out:

Add the two "x" coordinates, then divide by two.

n order to divide by two, add the two "y" coordinates.  

Mid point  (X , Y) formula

X = ( x₁ + x₂ ) ÷ 2

Y = ( y₂ + y₂ ) ÷ 2

where ( x₁ , y₁)  co- ordinate of A ( 7 , -2 )

(x₂ , y₂ ) co- ordinate of B

 2 = ( 7 + x₂ ) ÷ 2

x₂ = -3

0 = ( -2 + y₂ ) ÷ 2

y₂ = 2

From the given parameters using Pythagoras theorem, we can say that No, the ladder will not reach a window that is 21.5 feet above the ground.

We are told that the ladder is 25 ft and leans against the wall and so this will be the hypotenuse of the right angle triangle formed with the building.

The horizontal distance from the base of the ladder to the building is 15 ft. Thus, this will be the base or adjacent side of the triangle.

I have drawn a triangle to show this measurements and so we can use Pythagoras theorem to find the vertical height from the top of the ladder to the ground.

BC² = AB² +  AC²

25² = 15² +  AC²

AC² = 25² - 15²

AC = √(25² - 15²)

AC = 20 feet

Since the ladder is a vertical height of 20 ft from the ground which is less than the height of the window from the ground then we cans ay that the ladder will not reach the window.

Slope = 2

The slope of coordinates ( 20 , 15 ) and (30 , 35) = 2

Here given two points (20, 15) and (30 , 35)

Formula to find slope = y2 - y1 / x2 - x1

Equation of line in ordinary form: y = 2x+0

Equation of  line  in standard (general) form: 2x - y = 3

What is Slope?

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

a) Ordinary form =>

Slope Intercept Form:

y = mx+b

where m is the slope of the line

(Δy/Δx)

and b is the y-intercept.

For a line with slope 2 and point (-3,-6), plug 2 in for m, -3 for x, -6 for y, and solve for b.

-6 = 2(-3) + b

-6 = -6 + b

6 - 6 = b

b = 0

The equation in slope intercept form is

y = 2x+0

b) Standard form =>

Point Slope Form:

(y - y1) = m(x - x1)

Where m is the slope of the line

(Δy/Δx), y1 is the y coordinate of a point, and x1 is the x coordinate of a point.

For a line with slope 2 and point (-3,-6), plug 2 in for m, -3 for x1, -6for y1,

(y - (-6)) = 2(x - (-3))

Standard Form:

Ax + By = C

Where A, B, and C are integers. To write an equation in standard form, rewrite the equation in point slope form so that it fits the formula for standard form.

(y - (-6)) = 2(x - (-3))

(y + 6) = 2(x + 3)

y + 6 = 2x + 3

2x - y = 6 - 3

2x - y = 3

Hence, Equation of line in ordinary form is y = 2x+0

Equation of  line  in standard (general) form is 2x - y = 3

Answer:

It meant that the results were more reliable and the average makes it more reliable.

Step-by-step explanation:

The researchers used data from ten trials and averaged them, rather than data from a single trial because the data from single trials are more likely to include errors.

Research the issue utilizing data from a number of sources. It is critical to understand what one is attempting to achieve while designing an experiment.

The first method is to average identical successive trials, in which the researcher simply compares mean values across groups of patients or treatment effects. Averaging, to some extent, presume that the behavior is random. This premise is often ignored. If there is something systematic going on, such as a trial-by-trial change in response owing to adaptation/learning or weariness, this is potentially highly significant clinical information that is lost when the trials are averaged.

Thus, the data from single trials are more likely to include errors

The x-intercept is 5, and the asymptote is located at x = 4.

The equation that represents a reflection in the x​ -axis of the graph of g(x) is y = -|x|.

We are given a function g(x). The function g(x) is defined as the modulus of x. The equation is : g(x) = |x|.

We need to find the equation that represents the reflection of the graph of g(x). The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point but leave the x-value the same.

Let h(x) be the function that represents the reflection of the function g(x).

h(x) = -g(x)

h(x) = -|x|

For any line, if you draw two right triangles using the line as the hypotenuse, we can say that; Yes, the triangles have to be similar because the sides of both triangles will have the same ratio.

From the attached diagram, we will assume any two right triangles are drawn on the line OP, and AB and A'B' as the hypotenuse on the same line OP.

Now, due to the fact that the slope of the line OP is constant and assume that it makes x° with the positive x-axis, then we can say that;

tan x = AC/BC = A'C'/B'C'

Thus;

AC/A'C' = BC/B'C'

Therefore, we can say that the sides of the two right triangles are in the same ratio and as such, Δ ABC and Δ A'B'C' are similar.

Therefore, all the right triangles will be similar.

Since the final statement is false, it's not possible to have a quadratic function with vertex (-4, 2) and with the point (-4, 0).
