In Euclidean geometric terms, which of the below would be the best description of a RAY? a. It is a straight object that consists of all of the points that are equal distance from a common point. b. It is a straight object that extends infinitely in opposite directions without any width or thickness. c. It is a straight object that begins at a point and extends forever in one direction. It could be considered half of a line. d. It is a straight object that consists of all of the points that exist between two different points.
Answer:
c. It is a straight object that begins at a point and extends forever in one direction. It could be considered half of a line.
Step-by-step explanation:
A ray is a line that begins at a point and extend forever in one direction. It has no end point. It has a start point but no end point. So, C is the correct answer.

Consider the equation Ax+By=−36. If the x-intercept is (−3,0) and the y-intercept is (0,9), what are the values of A and B?
Answer:
A= 12
B = -4
Step-by-step explanation:
( -3,0) & (0,9) should satisfy the equation Ax + By = -36
when ( -3,0)
-3A+ 0 = -36
A = 12
when (0,9)
0 + 9B = -36
B = -4
The value of A and B is 12 and -4.
Given that,
The equation is Ax + By = -36.And, the x-intercept is (-3,0) and the y-intercept is (0,9).Based on the above information, the calculation is as follows:
Ax + By = -36
When (-3,0)
So,
-3A+ 0 = -36
A = 12
Now
when (0,9)
So,
0 + 9B = -36
B = -4
Therefore we can conclude that the value of A and B is 12 and -4.

Which theorem is not a valid theorem to show that two triangles are congruent?
A. SAS Triangle Congruence Theorem
B. SSA Triangle Congruence Theorem
C. ASA Triangle Congruence Theorem
D. AAS Triangle Congruence Theorem
Answer:
B
Step-by-step explanation:
I got 100 on my test and that was my answer
This is about Knowledge of Congruence Theorems of Triangles.
Option B is not Valid
In Congruence theorems, we have 4 major types which are;
1) SSS Congruency Theorem; This one denotes Side - Side - Side and it means that if 3 sides of a triangle are equal to corresponding 3 sides of another triangle, then they are both congruent.
2) SAS Congruency Theorem; This one denotes Side - Angle - Side and it means that if 2 sides and one angle of a triangle are equal to corresponding 2 sides and one angle of another triangle, then they are both congruent.
3) ASA Congruency Theorem; This one denotes Angle - Side - Angle and it means that if 2 angles and the included side of a triangle are equal to corresponding 2 angles and the included side of another triangle, then they are both congruent.
4) AAS Congruency Theorem; This one denotes Angle - Angle - Side and it means that if 2 angles and the non-included side of a triangle are equal to corresponding 2 angles and the non-included side of another triangle, then they are both congruent.
Looking at the options, the only one that is not Valid is Option B.

((4)²)^x = 1/(4)³
4²^x = 4³
thus the powers are same then
2x =-3
x=-3/2Answer:
x = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Using the rules of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^m}[/tex]
Note that 16 = 4² and 64 = 4³ , then
[tex]16^{x}[/tex] = [tex]\frac{1}{64}[/tex] , can be expressed as
[tex](4^2)^{x}[/tex] = [tex]\frac{1}{4^3}[/tex] , that is
[tex]4^{2x}[/tex] = [tex]4^{-3}[/tex]
Since the bases on both sides are equal, then equate the exponents
2x = - 3 ( divide both sides by 2 )
x = - [tex]\frac{3}{2}[/tex]

Solve 17 < 5x – 8 < 22. How many integer solutions are there?
Answer:
0
Step-by-step explanation:
To find the number of integer solutions there are to the inequality, we need to separate [tex]x[/tex] so it is on its own.
[tex]17<5x-8 < 22[/tex] (given inequality)
[tex]25 < 5x < 30[/tex] (add [tex]8[/tex] )
[tex]5 < x < 6[/tex] (divide by [tex]5[/tex] )
Since there are no integers between [tex]5[/tex] and [tex]6[/tex], it means there are 0 integer solutions for the inequality [tex]17 < 5x - 8 < 22[/tex].

the radius of the small circle is 0.5 millimeters the area of the large circle is 28.26 squared millimeters calculate the area of the state of region
There is a typo in the question. Where it reads 'state of' should read 'shaded'
Answer:
[tex]A=27.47\ mm^2[/tex]
Step-by-step explanation:
Area of a Circle
Given a circle of radius r, its area can be calculated as follows:
[tex]A=\pi r^2[/tex]
The area of the shaded region can be found by subtracting the area of the large circle minus the area of the small circle.
We already know the area of the large circle:
[tex]A_l=28.26\ mm^2[/tex]
Now we calculate the area of the small circle of radius r=0.5 mm:
[tex]A_s=\pi\cdot 0.5^2[/tex]
Calculating:
[tex]A_s=0.79\ mm^2[/tex]
The area of the shaded region is:
[tex]A=A_l-A_s=28.26\ mm^2-0.79\ mm^2[/tex]
[tex]\mathbf{A=27.47\ mm^2}[/tex]

A florist prepares an order of daisies and roses. For every 5 daisies she orders 2 roes. What 2 equations show the relationship between the number of daisies d and the number of roses r ?
Answer:
[tex]d = 2.5r[/tex] and [tex]r = \frac{d}{2.5}[/tex]
Step-by-step explanation:
Given
5 daises to 2 roses
Required
Determine the relationship between them
The question shows a direct proportion between number of daises and roses.
i.e.
[tex]d\ \alpha\ r[/tex]
Where d = daises and r = roses
Convert the above expression to an equation
[tex]d = kr[/tex]
Make k the subject
[tex]k = \frac{d}{r}[/tex]
When d = 5 and r = 2;
[tex]k = \frac{5}{2}[/tex]
[tex]k = 2.5[/tex]
So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr
So:
[tex]d = 2.5 * r[/tex]
[tex]d = 2.5r[/tex] ----------- (1)
Make r the subject in (1)
[tex]r = \frac{d}{2.5}[/tex] ------------------------(2)
Hence, the relationships between d and r are:
[tex]d = 2.5r[/tex] and [tex]r = \frac{d}{2.5}[/tex]

Y=x^2-6x+3 help write the vertex form of the equation
Answer:
[tex]y=(x-3)^2-6[/tex]
Step-by-step explanation:
[tex]y=x^2-6x+3[/tex]
This is written in the standard form of a quadratic function:
[tex]y=ax^2+bx+c[/tex]
where:
ax² → quadratic termbx → linear termc → constantYou need to convert this to vertex form:
[tex]y=a(x-h)^2+k[/tex]
where:
(h,k) → vertexTo find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:
[tex]x=-\frac{b}{2a}[/tex]
Using your original equation, identify the a, b, and c terms:
[tex]a=1\\\\b=-6\\\\c=3[/tex]
Insert the known values into the equation:
[tex]x=-\frac{(-6)}{2(1)}[/tex]
Simplify. Two negatives make a positive:
[tex]x=\frac{6}{2} =3[/tex]
X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:
[tex]y=3^2-6(3)+3[/tex]
Simplify using PEMDAS:
[tex]y=9-18+3\\\\y=-9+3\\\\y=-6[/tex]
The value of y is -6 (3,-6). Insert these values into the vertex form:
[tex](3_{h},-6_{k})\\\\y=a(x-3)^2+(-6)[/tex]
Insert the value of a and simplify:
[tex]y=(x-3)^2-6[/tex]

What is the equation of this graphed line?
Answer:
[tex]y=-\frac{9}{8} x+7[/tex]
Step-by-step explanation:
The slope is found by doing the equation [tex]\frac{rise}{run}[/tex]. When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal [tex]-\frac{9}{8}[/tex].
The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.
The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

A man is standing next to a 24 ft tree. The man is 7ft tall with a shadow of 3ft. How long is the shadow of the tree?
Answer:
[tex]\approx10.29\text{ feet}[/tex]
Step-by-step explanation:
Please refer to the attachment.
By AA Similarity, the two triangles are similar.
Therefore, corresponding parts of them are proportional.
Therefore, we can write the following proportion:
[tex]\frac{7}{24}=\frac{3}{x+3}[/tex]
We will solve for x. Cross-multiply:
[tex]7(x+3)=24(3)[/tex]
Distribute:
[tex]7x+21=72[/tex]
Subtract 21 from both sides:
[tex]7x=51[/tex]
Divide both sides by 7. So, the value of x is:
[tex]x\approx7.2857[/tex]
However, that is only the value of x.
The shadow of the tree is (x+3).
Hence, we will need tot add 3 to our value. Therefore, the actual length of the shadow of the tree is approximately:
[tex]\approx10.2857\approx10.29\text{ feet}[/tex]
