Actually Welcome to the concept of Geometric Mean (leg) theorem.
So according to the rule, we know that, here altitude = h and left side is 6 and right side is 14 , so we get as,
==> altitude/left = right/altitude
==> h/6 = 14/h
==> h^2 = 14*6
==> h^2 = 84
2.) so now we apply the Pythagoras theorem in triangle ∆DCB
so we get as,
==> (14)^2 + h^2 = a^2
==> 196 + 84 = a^2
==> 280 = a^2
==> a = √280
==> after simplified => a = √70*4
==> a = 2√70 units
hence the correct answer is a => 2√70 units.

Answer:
(2, -3), (3, -3)
Step-by-step explanation:
y = x^2 - 5x + 3
y = -3
x^2 - 5x + 3 = -3
x^2 - 5x + 6 = 0
(x - 3)(x - 2) = 0
x - 3 = 0 or x - 2 = 0
x = 3 or x = 2
We are given y = -3.
Answer: (2, -3), (3, -3)
Answer:
(2, -3) , (3, -3)
Step-by-step explanation:
One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,
[tex]f(x)=x^2-5x+3[/tex]
Set this equation up, and solve to find the value of (x) that satisfies this requirement:
[tex]f(x)=x^2-5x+3=-3[/tex]
Inverse operations,
[tex]x^2-5x+6=0[/tex]
Factor, rewrite the quadratic equation as the product of two linear equations,
[tex](x-2)(x-3)=0[/tex]
Therefore the solutions are the following, the (x-coordinate) represents the input, and the (y-coordinate) represents the output.

Tiys earns $7 an hour owing her neighbors lawn.
Part A: create two variables and determine which is dependent and which is independent for this situation.
Part B list three order pairs to show the values of the two variables.
Part C write and equation to represent the relationship between the two variables.
Answers
Answer:
Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.
Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.
Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

After answering the question provided, we can predict that the result will be as by equation As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.
What is equation?A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.
A binomial distribution with the specified values of n and p has a mean of = np and a standard deviation of = sqrt(np(1-p)).
Inputting n = 261 and p = 1/5 results in:
μ = np = 261 × 1/5 = 52.2
5.28 is equal to sqrt(np(1-p)) = sqrt(261 1/5 4/5)
Calculating the minimal typical value of 2 is as follows:
μ − 2σ = 52.2 − 2 × 5.28 ≈ 41.64
The calculation for the maximum typical value + 2 is as follows:
μ + 2σ = 52.2 + 2 × 5.28 ≈ 62.76
These values are rounded to the nearest hundredth, giving us:
The range is 41.64 to 62.76.
As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.

Rational numbers are the type of numbers that can be written in fraction forms (1/b where a and b are integers and b ≠ 0). Rational numbers also include decimals that are repetitive (0.313131313131) and decimals that end (0.25).

a=12
Step-by-step explanation:
We must use SOH, CAH, TOA
SOH= Sin0=opp/hyp
CAH=Cos0=adj/hyp
TOA= Tan0=opp/adj
Since we have opposite and hypotenuse we use Sin ratio, in this case,
sin30°= [tex]\frac{a}{24}[/tex]
[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply
[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself
a=12
Answer:
a = 12
Step-by-step explanation:
To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;
Sin(30) = [tex]\frac{a}{24}[/tex]
Sin(30) * 24 = a
12 = a

The box plot shows the algebra scores of students in class A and class B.
The median score of class A is _____.
The interquartile range of class B is ____.
The difference of the medians of class A and class B is
the interquartile range of either data set.
Answers
Answer:
[tex]Mid(A) = 73[/tex]
[tex]IQR(B) = 8[/tex]
The difference of the medians of class A and class B is between the interquartile range of either data set.
Step-by-step explanation:
Given
The attached box plots
To answer this, see attached image for how to read a box plot
With reference to the attached image of how to read the box plot;
Solving (a): The median of class A
[tex]Mid(A) = 73[/tex]
Solving (b): IQR of class B
IQR is calculated as:
[tex]IQR =Q_3 - Q_1[/tex]
From the box plot of class B, we have:
[tex]Q_3 = 87[/tex]
[tex]Q_1 = 79[/tex]
So, we have:
[tex]IQR(B) = 87 - 79[/tex]
[tex]IQR(B) = 8[/tex]
Solving (c):
[tex]Mid(A) = 73[/tex]
[tex]Mid(B) = 82[/tex]
[tex]IQR(B) = 8[/tex]
IQR of class A is calculated as:
[tex]IQR =Q_3 - Q_1[/tex]
From the box plot of class A, we have:
[tex]Q_3 = 76[/tex]
[tex]Q_1 = 68[/tex]
So, we have:
[tex]IQR(A) = 78 - 68[/tex]
[tex]IQR(A) = 10[/tex]
The difference (d) between the medians is:
[tex]d =Mid(B) - Mid(A)[/tex]
[tex]d = 82 - 73[/tex]
[tex]d = 9[/tex]
From [tex]smallest[/tex] to [tex]largest[/tex], we have: 8, 9, 10
i.e. IQR(B), d, IQR(A)

Answers
Answer:
[tex]f(x) = \frac{2x}{5y+6}[/tex]
Step-by-step explanation:
Answer:
Below!
Step-by-step explanation:
f(x) = 2x/5x+6
Sub y for f(x) : y = 2x/5x+6
Swap x and y : x = 2y/5y+6
Multiply both sides by 5y+6 : 2y = (5y + 6) x
Distribute x : 2y = 5xy + 6x
Change sign : 2y - 5xy = 6x
Factor out y : (2-5x)y = 6x
Divide both sides by 2-5x : y = 6x/2-5x
Substitute for y : f^-1(x) = 6x/2-5x
Answer: f^-1(x) = 6x/2-5x
