What is triangle?A triangle is a geometric shape that consists of three line segments that connect to form three angles. These angles always add up to 180 degrees. A triangle has three sides and three vertices (corners). Triangles can have different shapes and sizes, and they are often classified based on the length of their sides or the size of their angles. Some common types of triangles include equilateral triangles (where all sides are equal in length and all angles are equal to 60 degrees), isosceles triangles (where two sides are equal in length), and right triangles (where one angle is a right angle, or 90 degrees). Triangles have many properties and are an important part of geometry and mathematics.
Here,
To determine the scale factor for the dilation that maps △ABC to △DEF, we need to find the ratio of the corresponding side lengths of the two triangles.
Since △ABC ∼ △DEF, we know that the corresponding angles of the two triangles are congruent. Therefore, angle B in △ABC corresponds to angle E in △DEF, and angle A in △ABC corresponds to angle D in △DEF.
Using the Pythagorean theorem, we can find the length of the missing side of △DEF:
DF² = DE² + EF²
6² =DE² + 4²
DE=√20

How many milliliter in 1 microliter?
From the given information provided, by converting the units there are 0.001 milliliters in 1 microliter.
This means that if you have 1 microliter of liquid, it is equal to 0.001 milliliters of liquid.
The conversion factor between milliliters (mL) and microliters (μL) is:
1 mL = 1000 μL
Therefore, to convert microliters to milliliters, you divide the number of microliters by 1000.
For example, if you have 500 μL of liquid, you can convert it to milliliters by dividing 500 by 1000:
500 μL / 1000 = 0.5 mL
So, 500 microliters of liquid is equal to 0.5 milliliters of liquid.

The result of a number, when decreased by 66 2/3%, is 432. Find the number
Answer:
1298/3 is the answer
Step-by-step explanation:
Answer:
1296
Step-by-step explanation:
Let the unknown number be x.
If 432 is the result of x being decreased by 66²/₃%, then 432 is 33¹/₃% of x since 100% - 66²/₃% = 33¹/₃%.
Therefore:
[tex]\implies 33\frac{1}{3}\%\;\textsf{of}\;x=432[/tex]
[tex]\implies \dfrac{33\frac{1}{3}}{100} \cdot x=432[/tex]
[tex]\implies \dfrac{33\frac{1}{3}x}{100} =432[/tex]
Multiply both sides of the equation by 100:
[tex]\implies 33\frac{1}{3}x =43200[/tex]
Rewrite 33¹/₃ as an improper fraction:
[tex]\implies \dfrac{100}{3}x =43200[/tex]
Multiply both sides by 3:
[tex]\implies 100x=129600[/tex]
Divide both sides by 100:
[tex]\implies x=1296[/tex]
Therefore, the number that when decreased by 66²/₃% is 432, is 1296.

Write an exponential function for a graph that passes through the points (3, 2.8) and (4, 5.6) . Write the function in the form y=a(b)x.
The formula of the given exponential function whose graph passes through the points (3, 2.8) and (4, 5.6) is :
y = 0.35* (2)ˣ
What is an exponential function?
When the input variable x appears as an exponent in the formula
f(x) = aˣ, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x. It is mostly used to determine exponential growth or decay.
When there is exponential growth, the quantity grows initially extremely slowly and subsequently quickly. Over time, the rate of change quickens. As time goes on, the rate of increase accelerates. In exponential decay, the quantity initially falls very quickly and then gradually. Over time, the rate of change slows. As time goes on, change happens at a slower rate.
The general formula of an exponential function is:
y = abˣ
It is said that points (3, 2.8) and (4, 5.6) are present on the graph of the given exponential function.
W can substitute these value values in the above formula.
2.8 = ab³
5.6 = ab⁴
Dividing the above equations,
2.8 /5.6 = b³/b⁴
1/2 = 1/b
b = 2
Now substituting this value in one of the equations to find the value of a.
2.8 = a. (2)³
a = 2.8/8 = 0.35
Therefore the formula of the given exponential function is :
y = 0.35* (2)ˣ

Z-scores can be either positive or negative, with a positive number signifying a score above the mean and a negative value signifying a score below the mean according to the z-score table.
The statistical measurement known as the Z-score describes the relationship between a value and the mean of a group of values. Z-score is quantified by the standard deviations from the mean. The mean score and the data point's score are equal when the Z-score is 0. The Z-score for a value that deviates by one standard deviation is 1.0. Z-scores are binary, with a positive value denoting a score above the mean and a negative value denoting a score below the mean.

Solve for lengths of the missing sides in each pair of similar triangles. Round to nearest tenth if if necessary jk kl
For the given similar triangles, the length of the missing side in the second triangle is 20.
To solve for the length of the missing side in the pair of similar triangles, we can use the SSS similarity theorem. The theorem states that 'if all three pairs of corresponding sides of two triangles are proportional, then the two triangles are similar'. Since the triangles are similar, the ratio of their corresponding sides will be equal.
The given measurements of the first triangle are 12, 18, and 24, and the measurements of the second triangle are 10, 15, and x. To solve for x, you can use the ratio of corresponding sides of similar triangles. The ratio for the sides of the first triangle are 12:18:24 and for the second triangle are 10:15:x. The ratio of the corresponding sides is 10:12, 15:18, and x:24.
We can set up a proportion using the given dimensions and solve for x.
The proportion will look like this:
12/10 = 18/15 = 24/x
Cross-multiplying and simplifying, we get:
12x = 240
x = 20
Therefore, the length of the missing side in the second triangle is 20.
Note: The question is incomplete. The complete question probably is: Solve for length of the missing side in the pair of similar triangles. The dimensions of one triangle are 12, 18, and 24, and the dimensions of the second triangle is 10, 15, and x. (These are corresponding measurements).

At what points does the helix r(t) = sin(t), cos(t), t intersect the sphere x2 + y2 + z2 = 26? (round your answers to three decimal places. If an answer does not exist, enter dne. ).
At (0.958, 0.287, 5) and (0.958, -0.287, -5) points, the helix r(t) = sin(t), cos(t), t intersect the sphere x^2 + y^2 + z^2 = 26.
The sphere x^2 + y^2 + z^2 = 26 is a sphere with center at the origin and radius sqrt(26).
The helix r(t) = sin(t), cos(t), t is parameterized by sine and cosine functions, which oscillate between -1 and 1.
To find the points at which the helix intersects the sphere, we need to find the values of t such that the distance between r(t) and the origin is equal to sqrt(26).
The distance between a point (x, y, z) and the origin is given by the formula:
d = sqrt(x^2 + y^2 + z^2)
So, substituting the values from r(t), we have:
d = sqrt(sin^2(t) + cos^2(t) + t^2)
Setting d equal to sqrt(26), we have:
sqrt(sin^2(t) + cos^2(t) + t^2) = sqrt(26)
Squaring both sides, we have:
sin^2(t) + cos^2(t) + t^2 = 26
Recall that sin^2(t) + cos^2(t) = 1, so we have:
1 + t^2 = 26
Subtracting 1 from both sides, we have:
t^2 = 25
Taking the square root of both sides, we have:
t = ±5
So, the two points of intersection are (sin(5), cos(5), 5) and (sin(-5), cos(-5), -5).
Rounding the results to three decimal places, we have:
(sin(5), cos(5), 5) = (0.958, 0.287, 5)
(sin(-5), cos(-5), -5) = (0.958, -0.287, -5)

Translation: 2 units left and 1 unit down. Q(0,-1), D(-2,2), V (2,4), J(3,-3)
Translation: 2 units left and 1 unit down. Q(0,-1), D(-2,2), V (2,4), J(3,-3)
New coordinates are respectively, (-2, -2), (-4, 1), (0, 3), (1, -4)
What is the point?A point is a location of an object by taking reference of origin, In general case we consider it at (0,0), At the origin value of both the coordinate position is considered as Zero, In simple words point indicates how much it is above or below from the coordinate axes.
Vertical distance from the x axis is known as y coordinate and horizontal distance from the y axis is known as x coordinate.
Given the points Q(0,-1), D(-2,2), V (2,4), and J(3,-3),
we can see that each point has been translated 2 units to the left and 1 unit down.
This is because each x-coordinate has decreased by 2 and each y-coordinate has decreased by 1.
So, the translation of 2 units left and 1 unit down has moved each point along the plane in the negative x-direction and the negative y-direction.
the points are respectively (-2, -2), (-4, 1), (0, 3), (1, -4)
