A, B, C and D are the four corners of a rectangular plot marked out on level ground. given that the bearing of B from A is 040 degree and the bearing of C from A is 090 degree, calculate the bearing of:
a. B from C
b. A from C
c. D from C
The bearing of B from C based on the information given will be 40°.
How to depict the bearing?A bearing is an angle measured from the North direction clockwise. Notice that the bearing of B from C is 40° because according to the problem, all four points are on level ground, which means they are coplanar, and the angle between the plane and the North is 40°.
The bearing of A from C is also 110° because it's the bearing of C from A and A from C are same-side internal angles between parallels which must sum 180°.
The bearing of D from C is 40° too because that setup is parallel to the bearing of B from C.

A singles tournament had six players. Each player played every other player only once, with no ties. If Helen won 4 games, Ines won 3 games, Janet won 2 games, Kendra won 2 games and Lara won 2 games, how many games did Monica win
Monica win 2 games.
What is Expression?In maths, an expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)
According to the question,
First we look from the perspective of one player.
How many games does this person play? 5.
Now, each or the 6 people in the tournament played 5 games,
SO,
[tex]^{6} C_{2} = \frac{6!}{2! * 4!} = \frac{6*5}{2} = 15[/tex]
Therefore,
We know that there were a total of 15 games played.
This means, there were 15 losses, and more importantly, 15 wins.
Not counting Monica, there were:
4 + 3 + 2 + 2 + 2 = 13 wins.
This leaves,
15 − 13 = 2 wins for Monica.
Hence, 2 games won by monica in a tournament.

The area of a square is 256cm2. When each side of the square is increased by x cm, its area becomes 324 cm2.Find the value of x.
Answer: x = 2
Step-by-step explanation:
First, let's take the root of 256 to find the length of each side before the addition of x.
[tex]\sqrt{256} = 16[/tex]
This means 16 cm is the length of each side before the addition of x.
Then increase each side by X to get

The sides of a rectangle are represented by 4a-1 and 3a + 2. Find the expression for its perimeter.
Answer:
14a+2
Step-by-step explanation:
Perimeter of a rectangle: P=2(l+w) where l=length and w=width.
So P=2[(4a-1)+(3a+2)]=2(4a-1+3a+2)=2(4a+3a-1+2)=2(7a+1)=14a+2.
The expression to find the perimeter of the rectangle is 14a + 2.
What is Perimeter?Perimeter of a straight sided figures or objects is the total length of it's boundary.
Given that,
Sides of a rectangle is represented as 4a - 1 and 3a + 2.
Perimeter of a rectangle is represented as,
Perimeter = 2 (l + w)
Here l is the length and w is the width.
Substituting,
Perimeter = 2 (4a - 1 + 3a + 2)
= 2(7a + 1)
= 14a + 2
Hence the expression to find the perimeter is 14a + 2.

The radius of a circle is 7 metres. What is the length of a 135° arc?
Answer:
16.5 meters
Step-by-step explanation:
The length of an arc of a circle = 2πr(C/360°) ;where:
C is the central angle of the arc,
R is the radius of the arc
Length of the arc = 2π(7)(135/360)
= 16.493
= 16.5 metres (approx.)
Answer:
Arc Length: 5.25π or [tex]\frac{21}{4} \pi[/tex]
Explanation:
An arc is the part of the circumference of a circle.
Formula:
[tex]\sf Arc \ Length = \dfrac{\theta}{360} \ \times \ 2\pi \ \times radius[/tex]
If applied:
[tex]\sf Arc \ Length = \dfrac{135}{360} \ \times \ 2\pi \ \times 7[/tex]

What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
Let's consider an angle CAD be t.
In a triangle ABD
x + 90 + t = 180
t = 180 -x - 90
t = 90 - x ( by angle sum property)
Now, we know that the sum of the corresponding angle on a transversal is 180
So,
Angle A + angle D = 180
2x + t + x + x = 180
substitute the t value
2x + 90 - x + 2x = 180
3x + 90 = 180
3x = 90
x = 30 degree
Hence, the value of x would be 30 degrees.

the graph of F(x) can be stretched vertically and flipped over the x axis to produce the graph of G(x) if F(x)=x^2 which of the following could be the equation of G(x)
A. G(x)=-1/5x^2
B. G(x)=-5x^2
C. G(x)=5x^2
D. G(x)=1/5x^2
Answer:
g(x) = -5x²
(option B)
Step-by-step explanation:
we know that our original graph, f(x) = x² is a parabola.
So, we can consider what happens when we adjust the function/equation of a parabola.
when we "vertically stretch" a parabola, we are increasing the value of x.
think of it this way: the steepness of a slope is rise over run. If we rise ten, and run one, that's going be a lot more steep than if we rise 1, run 1.
Let's say our x = 5
if f(x)=x²
f(5) = 25
> y value / steepness is 25
f(x) = 3x²
f(5) = 75
> y value / steepness is 75
So, we are looking for an equation with an increase in x present.
When a parabola has been flipped over the x-axis, we know that the original equation now includes a negative
suppose that x = 1
if y = x² ; y = 1² = 1
if y = -(x²) ; y = -(1²) ; y = -1
So, when we set x to be negative, we make our y-values end up as negative also (which makes the graph look as if it has been flipped upside-down)
This means that we are looking for a function with a negative x value.
So, we are looking for a negative x-value that is multiplied by a number >1
The graph that fits our requirements is g(x) = -5x²
