Find center and radius of a circle with a diameter that has endpoints of (3,-2) and (-5,-4)
Answer:
Center: (-1,-3)
Radius: 4.12 units
Step-by-step explanation:
Hi there!
1) Find the center of the circle
When given two diameter endpoints, we can find the center of the circle by calculating for the midpoint since the center lies in the middle of the points:
Midpoint: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the diameter endpoints (3,-2) and (-5,-4)
[tex](\frac{3+(-5)}{2} ,\frac{-2+(-4)}{2})\\(\frac{3-5}{2} ,\frac{-2-4}{2})\\(\frac{-2}{2} ,\frac{-6}{2})\\(-1,-3)[/tex]
Therefore, the circle is centered at (-1,-3).
2) Find the radius of the circle
The radius of a circle is the distance between the outside edge and the center. We can find the radius by calculating for the distance between the center of the circle and one of the diameter endpoints.
Distance formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the center (-1,-3) and a diameter endpoint (3,-2)
[tex]d=\sqrt{(3-(-1))^2+(-2-(-3))^2}\\d=\sqrt{(3+1)^2+(-2+3)^2}\\d=\sqrt{(4)^2+(1)^2}\\d=\sqrt{16+1}\\d=\sqrt{17} \\d=4.12[/tex]
Therefore, the radius of the circle is approximately 4.12 units when rounded to the nearest hundredth.

which expression represents the difference of (5x-3y) and (8x+8y)?
Given:
The expressions are:
[tex](5x-3y)[/tex] and [tex](8x+8y)[/tex]
To find:
The difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex].
Solution:
Difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is written as:
[tex]Difference=(5x-3y)-(8x+8y)[/tex]
On simplification, we get
[tex]Difference=5x-3y-8x-8y[/tex]
[tex]Difference=(5x-8x)+(-3y-8y)[/tex]
[tex]Difference=-3x-11y[/tex]
Therefore, the difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is [tex]-3x-11y[/tex].

brainliesttt!! Which of the following are possible rational roots of the polynomial function?
Check all that apply.
F(x) = 3 x2 - 3x + 5
The possible rational roots of the polynomial function are [tex]\pm 1[/tex], [tex]\pm 1/3[/tex], and [tex]\pm5[/tex] and this can be determined by using the given data.
Given :
[tex]\rm F(x) = 3x^2-3x+5[/tex]
The following steps can be used in order to determine the possible rational roots of the polynomial function:
Step 1 - Write the given polynomial equation.
[tex]\rm F(x) = 3x^2-3x+5[/tex]
Step 2 - The rational roots are the factors of the constant divided by the factors of the coefficient of [tex]\rm x^2[/tex].
Step 3 - So, the possible roots of the polynomial function are:
[tex]\dfrac{c}{a} = \dfrac{5}{3}=\pm \left(1,\dfrac{1}{3},5,\dfrac{5}{3}\right)[/tex]
Therefore, the correct options are A) [tex]\pm 1[/tex], B) [tex]\pm5[/tex], and C) [tex]\pm 1/3[/tex].

A. y−4=−611(x−1)
B. y+1=−611(x+4)
C. y+7=−611(x−7)
D. y−7=−611(x+7)
Answer:
D) y-7=-6/11(x+7)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-7)/(4-(-7))
m=-6/(4+7)
m=-6/11
y-y1=m(x-x1)
y-7=-6/11(x-(-7))
y-7=-6/11(x+7)
y=-6/11x-42/11+7

Find the value of x. The diagram is not to scale.
Answer:
[tex]x=14[/tex]
Step-by-step explanation:
Since lines [tex]\overrightarrow{f}[/tex] and [tex]\overrightarrow{g}[/tex] are parallel, the angles labelled in the diagram must be supplementary (add up to [tex]180^{\circ}[/tex]). Therefore, we have the following equation:
[tex]4x+(7x+26)=180,\\11x+26=180,\\11x=154,\\x=\boxed{14}[/tex]

Find the values of x and y
Answer:
x = 78º
y = 35º
Step-by-step explanation:
These are isosceles triangles
two angles are congruent
-----------------------------
x + 51 + 51 = 180
x = 180 - 102
x = 78º
y + y + 110 = 180
2y = 70
y = 35º
a triangle has side lengths 10, 16, and 11. is the triangle actue, obtuse, or right?
Answer:
Obtuse
Step-by-step explanation:
a^2 + b^2 = c^2
10^2 + 11^2 = 16^2
100 + 121 = 256
221 = 256
221 < 256
A triangle has side lengths 10, 16, and 11. is the triangle is obtuse.
Name three types of triangles based on angles?Triangles can be classified into three types with respect to their interior angles which are:
1. Acute-angled
2. Obtuse-angled
3. Right-angled
Acute Triangle
An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.
Obtuse Triangle
Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.
Right Triangle
A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse.
Three given sides are 10, 11, 16
Let a = 10, b = 11, c = 16
then, [tex]a^{2} +b^{2} = 10^{2} +11^{2}[/tex]
= 100 + 121
= 221
and [tex]c^{2} = 16^{2} =256[/tex]
Since, [tex]a^{2} +b^{2} < c^{2}[/tex]
Thus, given triangle is obtuse.

Answer:
60°
Step-by-step explanation:
just in case if line AC and BD are straight lines,
angle EGD will be 180-90-30=60
and EGD will equal to x°becoz they are just in opposite
Answer:
The Answer is 60
Step-by-step explanation:
If you look at E B and F those make up a 180-degree angle if you look across from B then you will see that it is a 90-degree angle so you can assume that B is also a 90-Degree angle so if you add up 30 + 90 = 120
You then can subtract 180 - 120 to get the answer 60
So therefor the answer is 60
Keith has 7 yards of string. He needs ⅓ yard of string for each of his puppets. How many puppets can Keith make with his string?
Answer:
the no of puppets that could be made with his string is 21
Step-by-step explanation:
Given that
There is 7 yards
And, it needs one -third of string for each of his puppets
= 7 × 3
= 21 puppets
We simply multiply the 7 yards with the 3 so that the no of puppets could come
hence, the no of puppets that could be made with his string is 21
