what are the coordinates of that center of a circle if the endpoints of its diameter are a(8,-4) and b(-3,2)?
Answers
That is the x coordinate
You then need to add 2 and -4 together to get -2 and divide by 2 to get -1
This is the y coordinate
(2.5,-1)
The coordinates of that center of a circle with endpoints of its diameter at a(8,-4) and b(-3,2) is (2.5, -1)
The standard equation of a circle is:
(x - a)² + (y - b)² = r²
where (a, b) is the center of the circle and r is the radius of the circle.
Given the diameter endpoints at a(8,-4) and b(-3,2), let (x, y) be the center of the circle, hence:
[tex]x=\frac{8-3}{2} =2.5\\\\y=\frac{-4+2}{2}=-1[/tex]
Hence the center of the circle is at (2.5, -1)

Graphing Linear Inequalities
This is a graph of a linear inequality:
linear inequality y <= x +2
The inequality y ≤ x + 2
You can see the y = x + 2 line, and the shaded area is where y is less than or equal to x + 2
Linear Inequality
A Linear Inequality is like a Linear Equation (such as y = 2x+1) ...
... but it will have an Inequality like <, >, ≤, or ≥ instead of an =.
How to Graph a Linear Inequality
First, graph the "equals" line, then shade in the correct area.
There are three steps:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
Let us try some examples:
Example: y≤2x-1
1. The inequality already has "y" on the left and everything else on the right, so no need to rearrange
2. Plot y=2x-1 (as a solid line because y≤ includes equal to)

Find the measure of angle C of a triangle ABC, if: m∠A = α, m∠B = 2α Find m∠C

Step-by-step explanation:
By angle sum postulate of a triangle.
[tex] m \angle \: A+ m \angle \: B + m \angle \: C = 180 \degree \\ \alpha + 2 \alpha + m \angle \: C = 180 \degree \\ 3 \alpha + m \angle \: C = 180 \degree \\ \huge \red{ \boxed{\angle \: C = 180 \degree - 3 \alpha}} \\ [/tex]

What is triangle?" Triangle is defined as the two dimensional geometrical shape with three sides , three vertices and three angles enclosed in it.Sum of all the interior angles in a triangle is equals to [tex]180\°[/tex]. "
According to the question,
In a triangle [tex]ABC[/tex],
Given measure of angles,
[tex]m\angle A = \alpha \\\\m\angle B = 2\alpha[/tex]
Sum of all the interior angles in a triangle is equals to [tex]180\°[/tex].
Therefore,
[tex]m\angle A + m\angle B + m\angle C = 180\°[/tex] ________[tex](1)[/tex]
Substitute the value of [tex]m\angle A , m\angle B[/tex] in [tex](1)[/tex] we get,

Answers
Start by setting up your two sets of parenthses.
X² breaks down into x and x.
What we are looking for is factors of the constant term
that add to the coefficient of the middle term.
The question is, what is the coefficient of the middle term
in this problem if there is nothing written in front of the x.
Well if there is nothing written there,
the coefficient is understood to be 1.
So what we are looking for are factors of -12 that add to -1.
Factors of -12
+12 · -1
-12 · +1
+6 · -2
-6 · +2
+4 · -3
-4 · + 3
We can see that -4 and +3 add to -1.
So they go in the second position of each binomial.

Answer:
[tex]y<-4x+3[/tex]
Step-by-Step Explanation:
We want to find the slope-intercept inequality for the graph shown.
First, we will need to determine the equation of the line. We are given two points: (1, -1) and (2, -5). Let’s use the two to determine the slope. The slope formula is given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (1, -1) be (x₁, y₁) and let (2, -5) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{-5-(-1)}{2-1}=\frac{-4}{1}=-4[/tex]
So, our slope is -4.
Now, we can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, let’s substitute -4 for m. For consistency, we will let (1, -1) be (x₁, y₁). Hence:
[tex]\displaystyle y-(-1)=-4(x-1)[/tex]
Distribute:
[tex]y+1=-4x+4[/tex]
Subtract 1 from both sides:
[tex]y=-4x+3[/tex]
Finally, we can determine our sign.
Notice that our line is dotted. Therefore, we do not have “or equal to.”
Also, notice that the area shaded is below our line. Therefore, our y is less than our equation .
So, our symbol should be ”less than.”
Therefore, our equation is:
[tex]y<-4x+3[/tex]
=============================================================
We need to find the equation for the boundary line. It goes through the two points (1,-1) and (2,-5)
Find the slope of the line through (x1,y1) = (1,-1) and (x2,y2) = (2,-5)
m = (y2 - y1)/(x2 - x1)
m = (-5 - (-1))/(2 - 1)
m = (-5 + 1)/(2 - 1)
m = -4/1
m = -4 is the slope
Plug m = -4 and (x1,y1) = (1,-1) into the point slope formula. Solve for y.
y - y1 = m(x - x1)
y - (-1) = -4(x - 1)
y + 1 = -4(x - 1)
y + 1 = -4x + 4 ... distributing
y + 1 - 1 = -4x + 4 - 1 ... subtracting 1 from both sides
y = -4x + 3 is the equation of the boundary line
The blue shaded region tells us to consider all points below this boundary line as solutions. So we will use a "less than" sign to indicate this
We go from y = -4x+3 to y < -4x+3 which is the answer we want.
We do not have a line under the inequality sign. Simply because the boundary is a dashed line, so we exclude points on the boundary line as solutions. If we had [tex]y \le -4x+3[/tex], then the boundary line would be solid and it would tell the reader "points on the boundary line are part of the solution set".

Answer:

Hi, since the situation forms a right triangle (see image attached) the angle formed between his home and the library is 90°.
The sum of the interior angles of a right triangle is 180°, and the right angle (90°)is the largest angle formed.

B:into itself,and thought no more can trace
C: Are graven,till the characters be grown
D: Whereon the linements of that dead face
explain answer this question is English
Answers
Answer:
A: Tis the melodious hue of beauty thrown .
Explanation:
An appeal to the sense of hearing and sight will be something that presents an act that gives the readers a sense of the sounds in the writing. While an appeal to the sense of sight will present an image or a form of the picture to the readers. These types of sense appeals are used by writers to engage their readers' interest and keep them hooked.
In Percy Bysshe Shelly's poem "On the Medusa of Leonardo Da Vinci in the Florentine Gallery", the poet talks about the goddess Medusa but most importantly talks about the painting of "Medusa" by Da Vinci. The poem structured in the iambic pentameter scheme presents an image of Medusa and also how she was depicted by Da Vinci in his work. Out of the given options from the second stanza of the poem, the line that appeals to the sense of hearing and sight is "Tis the melodious (hearing/ sound) hue of beauty thrown (sight)".
Thus, the correct answer is option A.
A function that models the profit for a new pet-monitoring system shows that there is no profit made until the price reaches

the function?
Graphing
Answers
Answer:
The graph that best fits this model of profit and price per unit is attached to this solution.
Step-by-step explanation:
A couple of graphs are missing from the question. According to the full question as obtained online, there are a number of graph options, and we are expected to pick the best option. I would not add all the other graphs to limit the chances of deletion due to violating community guidelines.
The function is to model the profits of a new pet-monitoring system, so, if the profits are y and x is the price per unit, y = f(x)
The profits vary as the price per unit varies, there is no profit made until the price reaches
$95 per unit, a maximum profit at a price of $140 per unit, and no profit at a price over $185 per unit.
This description of the curve shows that y is negative at values of x less than $95, then the profits increase when x varies between $95 and $140. The profits reach a maximum at $140 and then the profits start to decline as x increases again, the profits go to 0 at x = $185.
This description shows that the function is a quadratic function with a graph that is n-shaped, peaking at x=185 and the graph crosses the x-axis at x=95 and x=185.
The most fitting graph for this model is attached to this solution provided.
From the graph, all the descriptions above are evident.
