What is √84 simplified
The simplified form of √84 is 2√21.
To simplify the given value, first, we need to write down the prime factorization of 84.
The prime factorization of 84 = 2² × 3 × 7
Therefore,
√84 = √(2² × 3 × 7)
Applying the radical rule: √ab = √a × √b, we get
√84 = √2² × √(3 × 7)
Applying the radical rule: √a² = a, for a ≥ 0, we get
√84 = 2 × √(3 × 7)
Multiply the numbers 3 and 7 we get 3 × 7 = 21
√84 = 2 × √21
√84 = 2√21
Therefore, the simplified form of √84 is 2√21.

Answer:
[tex]f(x) = 12 + \frac34x[/tex]
Step-by-step explanation:
Hello!
Function notation simply means replacing the term y with f(x).
Given the equation: y = 3/4x + 12
f(x) = 3/4x + 12The equation in function notation is [tex]f(x) = \frac34 x + 12[/tex].
What does f(x) mean?The meaning of f is just the name of the function. x is the variable being used in the function. Therefore, it can also be written as g(y), s(d), or e(f), as long as the variable inside the parenthesis exists in the equation.
Suppose you see a number in the spot for the variable. In that case, you are replacing the variable in that equation to evaluate when the x-value is that number.
Ex:f(x) = 2xf(1) = 2(1)f(1) = 2Interpreting this will tell you the value of y when x is 1. The y-value is 2.
Arc XY located on circle A has a length of 40 centimeters. The radius of the circle is 10 centimeters. What is the measure of the corresponding central angle for XY in radians?
The measure of the corresponding central angle for XY in radians is; 229.1°
What is the angle subtended by the arc?We know that an arc is a part of the entire perimeter of a circle.
Radian is defined as a unit of plane angular measurement that is equal to the angle subtended by the circle at the center by an arc that is of the length equal to the radius.
We also know that the circle as a whole contains 2π radians. Now, at first we are required to find the perimeter of the circle.
Perimeter of the circle is given by the formula 2πr.
Thus, perimeter of the circle = 2πr = 2π * 10 =20π = 62.851cm
Hence value of arc in radians = 40/62.851 * 2π = 0.636 x 2 π = 1.272π
Radian can be converted to degree by multiplying the radian measure by 180/π
Therefore, angle subtended by arc in degrees =1.272 π * 180 /π =229.1 °
Hence the angle subtended by arc is 229.1°

What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
The distance between the center of the circle to any point in the circle is called the radius of the circle, while the diameter is twice this distance.
Given that the range of the router, which services the wifi connection of the school has a diameter of 3.5 meters. Therefore, the radius of the wifi will be,
Radius = Diameter/2 = 3.5 meters / 2 = 1.75 meters

an exterior angle of a triangle is 105 degree and one of its interior opposite angle is 35 degree less than the other .calculate the measure of both interior angle
The value of both the interior angles of the triangle is calculated as 70° and 35°.
What is the exterior angle property?If a triangle side is formed, the exterior angle made is equal to the sum of a 2 interior opposite angles.
When an equivalent angle is chosen to take at each vertex of the triangle, this same exterior angles always add up to 360°.Each exterior angle equals 180° minus the interior angle. If the relating interior angle is given, this formula can be used. Exterior angle = Sum of opposite angles on the inside. When the exterior angle's distant interior opposite angles are given, this formula can be used to find it.Now, as per the given question;
The exterior angle of a triangle is 105°.
Let one of the interior angle is 'x'.
Then, the other interior angle is 35 degree less; x - 35°.
By the exterior angle property.
Sum of interior angles = exterior angle
x + x - 35° = 105°
2x = 105° + 35°
2x = 140°
x = 70°
The other interior angle is; x - 35°
= 70° - 35°
= 35°
Therefore, the two interior angles of the triangles are estimated as 70° and 35°.

⇒ (-2x -6y) + 6y = 18 + 6y
⇒ -2x -6y + 6y = 6y + 18
⇒ -2x = 6y + 18
⇒ [tex]\frac{2x}{2} = \frac{-6y + 18}{2}[/tex]

[We must multiply a term and an expression in order to enlarge this word.
We'll utilize the following product distributive property:
A(B + C) = AB + AC
⇒ -(2x + 2 * 3y) = 18
The final expression, in this case, will have two terms:
The first term is a product of '2' and 'x'
the second term is a product of '2' and '3y'.]
In this term, numerical components have been multiplied.
⇒ -(2x + 6y) = 18
We must group all the variable terms on one side of the equation and all the constant terms on the other in order to solve this linear equation.
⇒ (-2x -6y) + 6y = 18 + 6y
Here, the '-' (minus) term, -6y will be moved to the right side.
When a term "moves" from one side of the equation to the other, you'll notice that its sign changes.
Parentheses around expressions must be eliminated.
Each term in the expression changes sign if a negative sign is placed in front of it. Otherwise, the expression stays the same.
There is no negative sign in the situation.
⇒ -2x -6y + 6y = 6y + 18
In order to join like terms in this expression, we must first sum all of the numerical coefficients and, if necessary, replicate the literal section.
Nothing in a number suggests a value of 1.
There is just one set of related terms: -6y, 6y.
⇒ -2x = 6y + 18
We must eliminate the coefficient that multiplies the variable in this linear equation in order to isolate it.
If both sides are divided, then the coefficient must be removed (-2)
⇒ [tex]\frac{2x}{2} = \frac{-6y + 18}{2}[/tex]
We must simplify this fraction to its simplest form.
To do this, divide the variables that occur in both the numerator and the denominator.
The common factor, in this case, is 2.
⇒ [tex]x = \frac{-(2*3)y + (2*3)^{2} }{2}[/tex]
We must consider the GCF (Greatest Common Factor).
The GCF and the original expression, split by the GCF, provide the final term.
⇒ [tex]\frac{-2*3\frac{2*3y}{2*3} + \frac{(2*3)^{2} }{2*3} }{2}[/tex]
GCF in this case is 2*3.
The fraction [tex]\frac{2*3y}{2*3}[/tex] must be lowered to its simplest form. To do this, divide the variables that occur in both the numerator and the denominator.
Here, the common factor is 2*3.
⇒ [tex]x = \frac {2*3(y + (3)^{2 - 1}) }{2}[/tex]
The expression must be lowered to its simplest form.
Driving out the components that exist in both the numerator and the denominator will accomplish this.
2*3 is a common factor.
⇒ [tex]x = \frac{-2*3(y + 3)}{2}[/tex]
Numerical terms in the factor {y + (3²⁻¹)} is added which makes it (y + 3)
The fraction will then be broken down into its smallest terms next.
To do this, divide the variables that occur in both the numerator and the denominator.
2 is the common factor.
⇒ x = -[3(y + 3)]
⇒ x = -(3y + 3*3)
We must multiply a term and an expression in order to expand this term.
We'll utilize the following product distributive property:
A=AB+AC = A(B + C)
The final expression, in this case, will have two terms:
"3" and "y" are the product in the first term.
The second term is the result of the numbers 3 and 3.
⇒ x = -(3y + 9)
This term's numerical terms have been multiplied by three (3*3 = 9).
⇒ x = - 3y - 9
The parenthesis around expressions must be eliminated.
Each term in the expression changes sign if a negative sign is placed in front of it.
Otherwise, the expression stays the same.
The signs of the following two terms will now change. -(3y + 9) = - 3y - 9

The area of a rectangular carpet is given by the quadratic function A(x) = x(x + 30), where A(x) is the area and x is the width of the carpet in feet. What are the restrictions on the domain of the function and its inverse?
The inverse of the function is; f⁻¹(x) = - 15 ± √(x + 225)
What is the Inverse of the Function?We have been given a quadratic function f(x) = x(x + 30) and we need to restrict the domain such that it becomes a one to one function.
Now, the given function can also be written in vertex form as;
f(x) = (x + 15)² - 225
We know that vertex of this quadratic function occurs at (-15, -225).
Further, we know that range of this function is (-225, ∞).
If we restrict the domain of this function to either (-∞, -225) or (-225, ∞) , it will become one to one function.
Let us know find its inverse;
y = (x + 15)² - 225
Upon interchanging x and y, we get:
x = (y + 15)² - 225
Solving for y gives;
y = - 15 ± √(x + 225)

f⁻¹(x) = - 15 ± √(x + 225)

The irreversible loss of an island from over 100 acres in size to less than 3 acres is an example of?
The irreversible loss of an island from over 100 acres in size to less than 3 acres is an example of the irreversible nature of human change.
Human activity has lead to the change of Earth's climate in unimaginable ways over the last thousand years. Some of these changes are so significant that they are practically inevitable and irreversible.
Due to global warming, the planet's temperature is increasing gradually every year. This change in climate causes polar ice caps to melt and increases the water level.
Islands, which are pieces of land in between water bodies, are reducing in size due to this. The increased water level submerges some or all parts of an island. This is especially threatening for small islands.
This is not only dangerous for the human and wildlife population of these islands, but also for the general habitability. Due to frequent flooding, soil salinity increases and this makes it difficult to cultivate these islands.

BD bisects ZABC. Solve for x and find mABC.
m/ABD = 11x - 10, m/CBD = 8x + 2
The value of x is 4 and the value of ∠ABC is 68°.
To solve this problem we first have to understand the concept of an angle bisector. Angle bisector is a straight line passes through the vertex of an angle dividing the angle in two equal angles.
According to the condition BD bisects ∠ABC
Therefore the two angles formed by the angle bisector are ∠ABD and ∠CBD.
The angle value of these two angles are equal.
Given:
m∠ABD=11x-10
m∠CBD=8x+2
Therefore from the above condition:
m∠ABD=m∠CBD
Substituting the values we get:
11x-10=8x+2
Solving the linear equation to find the value of x.
[tex]or,11x-10=8x+2\\or,11x-8x=2+10\\or,3x=12\\or,x=4[/tex]
Now let us find the value of ∠ABC
m∠ABC=m∠ABD+m∠CBD
or,∠ABC=11x-10+8x+2
or,∠ABC=19x-8
Substituting the value x=4 in the equation we get:
m∠ABC=19×4-8
or,m∠ABC=68°
Therefore we can conclude that the value of xis 4 and the value of ∠ABC is 68°.
