Answer:
26.31
Step-by-step explanation:
Use distance formula
d = [tex]\sqrt{(x_{2}-x_{1)^{2} + (y_{2}-y_ ^{1)^2} } }[/tex]
substitute in points and solve
d = [tex]\sqrt{(7-3)^2 + (23-(-3))^{2} }[/tex]
d = [tex]\sqrt{4^{2}+26^{2} }[/tex]
d = [tex]\sqrt{16 + 676}[/tex]
d = [tex]\sqrt{692}[/tex]
d = 26.30589288
d = 26.31 rounded
instructions: state what additional information is required in order to know that the triangle in the image below are congruent for the reason given
***I need help before it’s due**
SSS (side-side-side) requires that all three sides of the potentially congruent triangles be congruent.
Triangle WVU & Triangle UBW are our two triangles.
The middle line, UW and WU are congruent by the reflexive property, so that is not the information we need to prove SSS.
For SSS, we need to know that sides WV and UB are congruent.

The transformation of the parent graph of y = √x to y = (1/2)√x is a vertical compression by a factor of 1/2.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
As per the shown graph, for any value of x, the output of the function y = (1/2)√x is half of the output of the function y = √x. This means that the y-values of the transformed graph are compressed vertically by a factor of 1/2 compared to the parent graph, while the x-values remain unchanged.
Visually, the graph of y = (1/2)√x will be flatter and closer to the x-axis than the graph of y = √x, with the same x-intercepts (0,0) and (1,1).
Thus, the y-values of the transformed graph are compressed vertically by a factor of 1/2 compared to the parent graph.

Decide if the following scenario involves a permutation or combination. Then find the number of possibilities.
Ndiba and Kristin are planning trips to ten countries this year. There are 13 countries they would be interested in visiting. They are deciding which countries to skip.
Answer: 286 possibilities
Step-by-step explanation:
It's a combination because the order of countries doesn't matter in this scenario.
n = 13r = 10[tex]_{n} C_{r} =\frac{n!}{r!(n-r)!}=\frac{13!}{10!(13-10)!}=\frac{13!}{10!(3)!}=\frac{13!}{10!(3)!}\\\\=\frac{6227020800}{3628800(6)}=\frac{6227020800}{3628800(6)}=\frac{6227020800}{21772800}=286[/tex]

A box contains 6 red index cards, 3 yellow index
cards, and 4 green index cards. If Gabriella pulls out
2 cards at random from this box, without replace-
ment, what is the probability that both cards are
not green?
Answer:
11/15 = 73%
Step-by-step explanation:
because in total there are 15 cards and 4 of them is not green. You would want to see what is the probability of other colored carded after leaving out the green ones.
The probability that both cards drawn from the box are not green is 27/52.
To determine the probability that both cards drawn from the box are not green, we need to calculate the probability of each individual draw and multiply them together.
Initially, the box contains a total of 6 red index cards, 3 yellow index cards, and 4 green index cards.
For the first draw, there are a total of 13 cards in the box. Since we are interested in the probability of not drawing a green card, there are 13 - 4 = 9 non-green cards. Therefore, the probability of not drawing a green card on the first draw is 9/13.
For the second draw, there will be 12 cards left in the box. Since one green card has already been removed, there are now 12 - 3 = 9 non-green cards remaining. Thus, the probability of not drawing a green card on the second draw is 9/12.
To find the overall probability, we multiply the probabilities of each individual draw:
(9/13) * (9/12) = 27/52

Answer:
[tex]b=80[/tex]°
Step-by-step explanation:
The central angles theorem states that the measure of an angle whose vertex is the center of the circle is equivalent to the arc surrounding it. One can apply this here by stating that the measure of the arc surrounding the (90) degree angle is (90) degrees.
The total degree measure of a circle is (360). Thus one can form an equation and solve it to find the measure of the arc surrounding the angle (b). Call the arc surrounding angle (b); ([tex]b_1[/tex]).
[tex](b_1)+(90)+(110)=360[/tex]
Simplify,
[tex]b_1+200=360[/tex]
Inverse operations,
[tex]b_1+200=360[/tex]
[tex]b_1=160[/tex]
The peripheral angles theorem states that if the vertex of an angle formed between a tangent and a chord, is on the circumference (outer edge) of a circle, then the measure of the angle is equal to half of the measure of the surrouding arc. Please note that a chord is a line segment in a circle that intersects the circle in two points. A tangent is a line segment that intersects a circle at one point. One can apply this here by stating the following,
[tex]b=\frac{b_1}{2}[/tex]
Substitute,
[tex]b=\frac{160}{2}[/tex]
Solve,
[tex]b=80[/tex]

what is the explicit formula for this sequence
Answer:
A
Step-by-step explanation:
Start with the 3.
You know that there is a difference of 4 between (say) 2 and 5. The 3 is a sign that the sequence is increasing. The members of the sequence are going up.
n - 1 means that the nth terms is calculated as an and uses the number of terms to be n-1. That means that the first term is a1 which is the starting point of the sequence.
The answer is an = a1 + (n-1)*d
d = 3
a1 = - 7
So let's try the formula out.
a4 = -7 + (4 - 1)*3
a4 = -7 + 3 * 3
a4 = -7 + 9
a4 = 2

Yes, the triangles are similar by AA.
Yes, the triangles are similar by SSS.
Yes, the triangles are similar by SAS
Yes, the triangles are similar by ASA.
Answer:
Yes, the triangles are similar by SAS
Step-by-step explanation:
Looking at the picture, we see that there are two triangles with side lengths of different sides. We can deduce that the scale factor is 1 2/3, because 8 divided by 4.8 is 1 2/3, and 10 divided by 6 is the same. Now that we have clarified that the triangles share the same scale factor, we notice that the angle is also the same, as mentioned in the picture. This leads us to say that the triangles are similar by the SAS similarity theorem (Side, Angle, Side). I hope this helped and please don't hesitate to reach out with more questions!

Step-by-step explanation:
Option (b) is correct.
The sum of given expression \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}x2y3+2x3y4+xyy is 2xy\sqrt{y}+2xy^2\sqrt{x}2xyy+2xy2x
Step-by-step explanation:
Given:Expression \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}x2y3+2x3y4+xyy
We have to find the sum of the given expression and choose the correct from the given options.
Consider the given expression \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}x2y3+2x3y4+xyy .
\sqrt{x^2y^3}x2y3 can be written as \sqrt{x^2y^2y}=xy\sqrt{y}x2y2y=xyy
Also, 2\sqrt{x^3y^4}2x3y4 can be written as 2\sqrt{x^3y^4}=2\sqrt{x^2x(y^2)^2}=2xy^2\sqrt{x}2x3y4=2x2x(y2)2=2xy2x
Now, the given expression becomes,
x2y3+2x3y4+xyy
=xy\sqrt{y}+2xy^2\sqrt{x}+xy\sqrt{y}=xyy+2xy2x+xyy .
Now, adding like term, terms having same variable with same degree.
=2xy\sqrt{y}+2xy^2\sqrt{x}=2xyy+2xy2x .
Thus, The sum of given expression \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}x2y3+2x3y4+xyy is 2xy\sqrt{y}+2xy^2\sqrt{x}2xyy+2xy2x

Answer:
x = 6[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Here we need to use the Pythagorean Theorem
Pythagorean Theorem: a^2 + b^2 = c^2
STEP 1: Define your variables
The legs of the triangle are a and b, and the hypotenuse is c.
a = x
b = 4
c = 14
STEP 2: Plug your variables into the equation and solve
x^2 + 4^2 = 14^2
x^2 + 16 = 196
x^2 + 16 - 16 = 196 - 16
x^2 = 180
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{180}[/tex]
STEP 3: Simplify
Since the question asks you to put the equation in simplified radical form, you do not have to approximate the answer, but you do have to simplify the radical.
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{180}[/tex]
x = [tex]\sqrt{36}[/tex] * [tex]\sqrt{5}[/tex]
x = 6[tex]\sqrt{5}[/tex]
Find the distance between each pair of points. Round to the nearest tenth if necessary.
(-3, 6) (2,1)
Answer:
The distance between the two points is about 7.1 units.
Step-by-step explanation:
We want to find the distance between the two points (-3, 6) and (2, 1).
To find the distance between any two points, we can use the distance formula:
[tex]\displaystyle d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Let (-3, 6) be (x₁, y₁) and (2, 1) be (x₂, y₂). Substitute:
[tex]\displaystyle d=\sqrt{((2)-(-3))^2+((1)-(6))^2}[/tex]
Simplify:
[tex]\displaystyle d=\sqrt{(5)^2+(-5)^2}[/tex]
Evaluate:
[tex]d=\sqrt{25+25}=\sqrt{25(2)}=5\sqrt{2}\approx 7.1\text{ units}[/tex]
The distance between the two points is about 7.1 units.
