That's a Congruent Triangle question.
The first thing that we should to analize is it: What figure is EFGH? The question say for us that [tex]\overline{EF} \cong \overline{GH}[/tex] and [tex]\overline{EH} \cong \overline{GF}[/tex], therefore, EFGH is a parallelogram because its parallel sides are congruents (equals).
Now, we should to proof that [tex]\triangle EFH \cong \triangle GHF[/tex]. The simbol "≅" means congruence, that is, [tex]\triangle EFH \cong \triangle GHF[/tex] means that the triangles EFH and GHF are equals.
Let's proof:
[tex]\overline{HF}[/tex] is a diagonal of the parallelogram EFGH. When we have a diagonal in a parallelogram, the opposite angles are congruents (look at the picture: the blue angles are congruent and the red angles are congruents too). Therefore, [tex]E\hat{F}H \cong F\hat{H}G[/tex] and [tex]E\hat{H}F \cong H\hat{F}G[/tex].
Both triangle has a comum side: the diagonal [tex]\overline{HF}[/tex]. The diagonal [tex]\overline{HF}[/tex] is between two angles that we know that are congruents, Therefore, by the case ASA (Angle, Side, Angle), we proof that [tex]\triangle EFH \cong \triangle GHF[/tex].

What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the equation of the line that passes through the points (-4, 0) and (0, 4), we can use the point-slope form of the equation of a line as described in the definition.
First, let's find the slope of the line. We can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) = (-4, 0) and (x2, y2) = (0, 4):
m = (4 - 0) / (0 - (-4)) = 4 / 4 = 1
So the slope of the line is 1.
Next, let's choose one of the given points, say (-4, 0), and substitute its coordinates and the slope into the point-slope form:
y - 0 = 1(x - (-4))
Simplifying this equation, we get:
y = x + 4
So the equation of the line that passes through the points (-4, 0) and (0, 4) is y = x + 4.

Select the correct answer. Which function has a domain of all real numbers? A.y=(x+2)^ 1/4 B.y=-x^ 1/2+5 C.y=-2(3x)^1/6 D.y=(2x)^1/3-7
Answers
The option D shows a function has a domain of all real numbers.
Which is the Domain of a Function?
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.
Letter A - [tex]y=\left(x+2\right)^{^{\frac{1}{4}}\:}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]\left(x+2\right)^{^{\frac{1}{4}}\:}=\sqrt[4]{x+2}[/tex]
Therefore, the function domain is x [tex]\geq[/tex]-2.
Letter B - [tex]y=-x^{\frac{1}{2}}^{\:}+5[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-x^{\frac{1}{2}}^{\:}+5=-\sqrt{x} +5[/tex]
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter C - [tex]y=-2\left(3x\right)^{\frac{1}{6}}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-2\left(3x\right)^{\frac{1}{6}}=-2*\sqrt[6]{3x}[/tex]
3x [tex]\geq[/tex] 0
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter D - [tex]y=\left(2x\right)^{\frac{1}{3}}-7[/tex], as you have an odd exponent, the results for y has no undefined points nor domain constraints. Thus,[tex]\left(2x\right)^{\frac{1}{3}}-7=y=\sqrt[3]{2x} -7\\ \\[/tex]
Therefore, the function domain is [tex]-\infty \: < x < \infty \:[/tex].

Answers
The empire state building is taller than a chair seat by three orders of magnitude.
What are orders of magnitude?Orders of magnitude refer to the classification based on the sizes of two objects against each other.
Orders of magnitude range in the power of 10 or 10ⁿ.
Data and Calculations:Orders of Magnitude:
10x = 1 order of magnitude
100x = 2nd order of magnitude
1000x = 3rd order of magnitude
Empire State Building = 1,500 feet
Chair seat = 1.5 feet
Order of magnitude = 1,000x (1,500/1.5)
Thus, the Empire State Building is about a thousand times taller than a chair seat or three orders of magnitude.

For the numbers, count the negative signs. It the sum is an even number than the product is positive. If the sum is a negative number, then the product is negative. There are a total of 3 negative signs. This is a odd number so the product is negative

Step-by-step explanation:
Ravi présent âge 15 because présent would be 20:15 and then it would turn into 25:20
Answer:
15 years old
Step-by-step explanation:
Given the ratio of their ages = 4 : 3 = 4x : 3x ( x is a multiplier )
Then in 5 years the ratio of their ages is 4x + 5 : 3x + 5 = 5 : 4, that is
[tex]\frac{4x+5}{3x+5}[/tex] = [tex]\frac{5}{4}[/tex] ( cross- multiply )
4(4x + 5) = 5(3x + 5) ← distribute both sides
16x + 20 = 15x + 25 ( subtract 15x from both sides )
x + 20 = 25 ( subtract 20 from both sides )
x = 5
Thus
Ravi's age is 3x = 3 × 5 = 15
