Solving for B in the equation gives B = 5( h - m) / r
What is subject of formula?
A subject of formula can be defined as a variable that is expressed in terms of other variables in an equation or expression.
It is also known as the variable that is being worked out in an equation or given expression.
From the information given, we have the equation;
h = m + 1/5rB
To make 'B' the subject of formula, we have to take the following crucial steps;
Take 'm' over the equality sign
h - m = rB/ 5
Now, cross multiply
5( h - m) = rB
To make 'B' stand alone, divide both sides by r
B = 5( h - m) / r
Thus, solving for B in the equation gives B = 5( h - m) / r

Which angle number represents the linear pair of \angle FHC∠FHC?
The angle number that represents the linear pair of angle FHC is: angle 5.
What is the Linear Pair?The linear pair consists of two adjacent angles that are on a straight line, whose sum will be equal to 180 degrees when added together.
Thus, the two adjacent angles share a common side and a common vertex, and they are supplements of each other. That is, they have a sum of 180 degrees.
Angle 4 represents angle FHC. Angle 5 is adjacent to angle 4, and both lie on a straight line.
Therefore, angle FHC + angle 5 = 180 degrees.
In conclusion, we can state that, the angle number that represents the linear pair of angle FHC is: angle 5.

What is the range of the function?
{x | −2 ≤ x < 3}
{x | −2 < x ≤ 3}
{y | 0 ≤ y < 9}
{y | 0 < y ≤ 9}
The range of the quadratic function is {y |0 ≤ y < 9}
What is the range of a function?The range of a function is the set of output values of the graph. This in other words mean the range of a function is the set of y values of the graph.
How to determine the range of the function?From the question, we have the following parameters:
The parabola opens upwardVertex = (0, 0)Closed circle point = (-2, 4)Open circle point = (3, 9)Write out the vertex
So, we have
Vertex = (0, 0)
Remove the x value
y = 0
From the question, we have
The parabola opens upward
This means that the vertex is a minimum
So, the range is
y ≥ 0
Rewrite as
0 ≤ y
Recall that:
Closed circle point = (-2, 4)
Open circle point = (3, 9)
Remove the x values
Closed circle point = 4
Open circle point = 9
Remove the smaller y value
Open circle point = 9
This means that the highest value of y is at open circle point = 9
This is represented as
y < 9
So, we have
0 ≤ y and y < 9
Combine both
0 ≤ y < 9
Rewrite properly as
{y |0 ≤ y < 9}
Hence, the range of the quadratic function is {y |0 ≤ y < 9}

the middle of the river are 25° and 32° respectively.
Find the length of the bridge.
The length of the golden gate bridge is -163.250975.
What is trigonometry?
Trigonometry is the branch of mathematics that deals with particular functions of angles and how to apply them in calculations. There are six widely used angles-related trigonometric functions. Their respective names and acronyms are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What is length?
Length is a measure of distance. According to the International System of Quantities, length has the dimension of distance. Most measurement systems select a length base unit from which all other units are derived. The International System of Units' fundamental unit of length is the meter.

(x + 1)³ = 729
Now, using the identity (a + b)³ = a³ + b³ + 3ab(a + b), we get
x³ + 1 + 3x² + 3x = 729
x³ + 3x² + 3x - 728 = 0 : Equation 1
By hit and trial method x = 8 is the solution of the equation 1.
Now, by remainder theorem we can write the equation 1 as

Step-by-step explanation:
what relationship must hold for the point to be equidistant from the origin and the xz-plane? make sure that the relationship you state is valid for positive and negative values of a, b, and c
The relationship must hold for the point to be equidistant from the origin and the x z-plane is a^2+b^2+c^2 > b^2.
What is equidistant point:
A point is said to be equidistant from two other points when it is at an equal distance away from both of them. For example, the perpendicular bisector of a line segment is equidistant from both endpoints.
Now,
distance from P(a, b, c) and the Origin (0,0,0)
[tex]\sqrt{(a-0)^2+(b-0)^2+(c-0)^2} =\sqrt{a^2+b^2+c^2}[/tex]
distance from p(a ,b, c) and the x-z plane
[tex]\sqrt{(0-0)^2+(b-0)^2+(0-0)^2} = |b|[/tex]
Here,
P is equidistant from the Origin and the x - z plane
[tex]\sqrt{a^2+b^2+c^2} = |b|[/tex]
[tex]a^{2} +b^2+c^3 = b^2[/tex]
[tex]a^{2} +c^2 = 0[/tex]
Hence a=c=0 ,thus the point P must be of the form (0,b,0) for any b ∈R
Again,
point P far the from the origin than from the x z plane
[tex]\sqrt{a^2+b^2+c^2} > |b|[/tex]
[tex]a^{2} +b^2+c^2 > b^2[/tex]
[tex]a^{2} +c^2 > 0[/tex]
Hence a, c ∈R such that atleast one of the a ,b ,c is non-zero.
Therefore,
(a ,b ,c) for any b∈ R and for a, c ∈ R with atleast one of the a and c is non-zero.

The coach company charges £195 for the trip.
a Show that the money paid by the students and parents is not enough to pay for the
coach.
b How much should each teacher pay so that the cost of the coach is covered exactly?
c On the day of the trip, 8 students are ill and they get their money back. The
passengers on the coach share the extra cost equally. What is the extra payment for
each passenger?
Step-by-step explanation:
the total charge is £195.
we have 36 students. each paying £4.25.
we have 3 parents. each paying 2×£4.25 = £8.50
we have 3 teachers. each paying £0.
a.
the payments are
36×4.25 + 3×8.50 = 153 + 25.5 = £178.50
that is clearly below the total charge of £195.
there is a deficit of 195 - 178.5 = £16.50
b.
3 teachers.
so, each should pay
16.5 / 3 = £5.50
c.
8 students drop out.
that means
8× 4.25 = £34.00 are not paid.
we have now
28 students

Reflexive Property of congruence justifies the statement
∠K ≅ ∠K
The Reflexive Property of congruence states that any geometric figure is congruent to itself. The figures are being the reflection of itself. They have the line segments of same length, an angle has the same angle measure and the figure has same shape and size as itself.
If two triangles have a common side or a common angle, then Reflexive Property of congruence is used to prove that the two triangles are congruent.
Since the given angle is K, therefore by the Reflexive Property of congruence we could say that the angle K is congruence to angle K.

For questions 4-7, find the measures of the angles in the picture below.
(Questions shown in image)
Answer:
Measures of each angle are as follows:
4. ∠BXC = 20°
5. ∠FXE = 85°
6. ∠GXD = 75°
7. ∠BXF = 75°
Step-by-step explanation:
#4
∠BXC is opposite ∠EXD and so it is the same as ∠EXD = 20°
#5
∠FXE is opposite ∠CXG and so it is the same as ∠CXG = 85°
#6
Angles ∠CXG, ∠GXD and ∠EXD line on a straight line so the sum of these angles must be 180°
∴ m∠CXG + m∠GXD + m∠EXD = 180°
Substituting known values for ∠CXG and ∠EXD we get
85 + ∠GXD + 20 = 180°
105 + m∠GXD = 180°
m∠GXD = 180-105 = 75°
#7
∠BXF is opposite ∠GXD which we computed in #6 to be 75°
So m∠BXF = m∠GXD = 75°
a. What is the solution of √5 x-1 +3=x ? Check your results.
The solution is 10
Firstly rewriting the equation to frame the steps of solution -
√(5x-1) + 3 = x
Shifting 3 to the Right Hand Side of the equation -
√(5x-1) = x - 3
Now taking square of both sides of the equation
(√(5x-1))² = (x - 3)²
On solving the square we get the equation -
(5x - 1) = x² + 9 - 6x
Further solving the equation -
5x - 1 - 9 = x² - 6x
5x - 10 + 6x = x²
x² - 11x + 10 = 0
Solving the equation by factorizing -
x² - 1x - 10x + 10 = 0
x (x - 1) - 10(x - 1) = 0
(x - 1) (x - 10) = 0
x = 1, 10
Keeping the value of x in equation to find the solution and check the results-
x = 1
√(5×1-1) +3 = 1
√(5 - 1) + 3 = 1
√4 + 3 = 1
2 + 3 = 1
5 = 1
x = 10
√(5×10-1) +3 = 10
√(50 - 1) + 3 = 10
√49 + 3 = 10
7 + 3 = 10
10 = 10
