Given that OA = 2x + 9y , OB = 4x + 8y and CD = 4x - 2y , explain the geometrical relationships between the straight line AB and CD.
It’s a 3 mark question sooo if someone could help then thanks.
The geometrical relationships between the straight lines AB and CD is that they are parallel to each other
How to determine the relationshipIt is important to note the following;
A drawn from the origin and passes through point A (a , b), then the equation of OA = ax + byIf a line is drawn from the origin and passes through point B (c , d), then the equation of OB = cx + dyWe find the equation of AB by subtracting OB from OA, thus AB = (c - a)x + (d - b)y
The slope of line AB =
⇒ OA= 2 x + 9 y
⇒ OA = 4 x + 8 y
⇒AB = OB - OA
⇒AB = (4 x + 8 y) - (2 x + 9 y)
⇒ AB = 4 x + 8 y - 2 x - 9 y
Collect like terms
⇒ AB = (4 x - 2 x) + (8 y - 9 y)
⇒AB = 2 x + -y
⇒ AB = 2 x - y
⇒ Coefficient of x = 2
⇒ Coefficient of y = -1
⇒ The slope of ab = [tex]\frac{-2}{-1}[/tex] = 2
For CD
⇒ CD = 4 x - 2 y
⇒Coefficient of x = -4
⇒ Coefficient of y = -2
⇒The slope of cd = [tex]\frac{-4}{-2}[/tex] = 2
Note that Parallel lines have same slopes
And Slope of ab = slope of cd
AB // CD
Therefore, the geometrical relationships between the straight lines AB and CD is that they are parallel to each other

pls help me I need the help I would appreciate it!!!
SOLUTION :-
Since, the pair of angles are supplementary
a + b = 180°
50° + b = 180°
b = 180° - 50°
→ b = 130°

Answer:
130°
Step-by-step explanation:
supplementary angles are two angles that add up to 180°
(they form a straight line)
So, because we know that ∠b and 50° are supplementary, they must add up to 180:
b + 50 = 180
- 50 -50 (subtract 50 from both sides to isolate b)
b = 130
So, ∠b [angle b] = 130°

The density of liquid a is 8 pounds per gallon and the density of liquid b is 6 pounds per gallon. what quantity of liquid b weighs the same as 30 gallons of liquid a?
40 gallons of liquid b weighs the same as 30 gallons of liquid a.
What is density?A substance's density is defined as its mass per unit volume (more specifically, the volumetric mass density; also known as specific mass). Although the Latin letter D may also be used, the sign most frequently used for density is (the lower case Greek letter rho). Density is mathematically defined as mass divided by volume.
where m is the mass, V is the volume and D is the density, which is sometimes roughly characterized as weight per unit volume, while this is incorrect scientifically; this quantity is more precisely known as specific weight.
For liquid a,
8= mass/30
For liquid b,
6=mass/volume
For the two masses to be equal,
240=6*volume
volume=240/6
volume=40

A door delivery florist wishes to estimate the proportion of people in his city that will purchase his flowers. Suppose the true proportion is 0.07. If 289 are sampled, what is the probability that the sample proportion will differ from the population proportion by more than 0.03
The probability that the sample proportion will differ from the population proportion by more than 0.03 is 0.99968.
Given the true proportion is 0.07, sample size 289.
We have to calculate the probability that the sample proportion will differ from the population proportion by more than 0.03.
Probability is the likeliness or chance of happening an event among all the events possible. The probability lies between 0 and 1.
Probability=number of items/ total items.
True proportion=0.07
n=289
sample population mean=0.07
Sample proportion standard error=[tex]\sqrt{pq/n}[/tex]
=[tex]\sqrt{0.07*0.93)/289}[/tex]
=[tex]\sqrt{0.0651/289}[/tex]
=[tex]\sqrt{0.00022}[/tex]

Probability that the sample proportion will differ from the population proportion by more than 0.03=P(I P-p I>0.03)
=P( I Z I>0.03*0.015)
=P ( I z I >0.0045)
=0.99968.
Hence the probability that the sample proportion will differ from the population proportion by more than 0.03 is 0.99968.

Option C: Triangle JKL and Triangle PQR can be shown to be congruent by a single rotation.How are they congruent?Note that:
If ∆MNO can be gotten from ∆ABC then ∆MNO ≅ ∆ABC
To solve for Reflection (x axis), it will be:
The coordinate note for the reflection is (x, y) will be: (x,-y)
Since ∆MNO M(-9, -4), N(-3, -4), and O(-3, -15).
Then the reflections will be:
M(-9, -4)- M1(-9,4)
N(-3, -4)- N1(-3,4)
O(-3,-15)-O1(-3,15)
To solve for Reflection (y axis), it will be:
The coordinate note for the Reflection is (x,y) will be (-x,y)
Since ∆M1N1O1 = M1(-9, 4), N1(-3, 4), and O1(-3, 15).
Then M1(-9, -4) - M2(9,4)
N1(-3, -4) - N2(3,4)
O1(-3,-15)- O2(3,15)
To solve for Translation
The coordinate note for the Translation is (x,y) will be (x+2,y+2)
Since ∆M2N2O2 = M2(9,4), N2(3,4), and O2(3, 15).
Then M2(9, 4) - M3(11,6)=A
N2(3,4) - N3(5,6)=B

Hence ∆MNO ≅ ∆ABC
To know the congruent by a single rotation.
If ∆JKL can be gotten from ∆PQR
Then ∆JKL ≅ ∆PQR
For Rotation of 90 degree in an anticlockwise position, then:
The coordinate note for the Rotation is (x,y) will be (-y, x)
So, ∆JKL = J(17, -2), K(12, -2), and L(12, 7).
J(17, -2)- J1(2,17)
K(12, -2) - K1(2,12)
L(12,7) - L1(-7,12)
To solve for translation
The coordinate note for the translation is (x,y) will be (x+10,y-14)
Then ∆J1K1L1 = J1(2, 17), K1(2, 12), and L1(-7, 12).
Hence J1(2, 17) - J2(12,3) = P
K1(2, 12)- K2(12,-2) = Q
L1(-7, 12)- L2(3,-2) = R
So, ∆JKL ≅ ∆PQR.

Question 6 The volumes of two similar solids are 729m3 and 125m3 The surface area of the larger solid is 324m2. What is the surface area of the smaller solid
Answer:
100 m²
Step-by-step explanation:
The scale factor for volume of similar figures is the cube of the scale factor for linear dimensions. The scale factor for area is the square of that linear dimension scale factor.
Scale factorIf the ratio of volumes is the cube of the scale factor, then the scale factor for the smaller figure in terms of the larger is ...
[tex]k=\sqrt[3]{\dfrac{125\text{ m}^3}{729\text{ m}^3}}=\sqrt[3]{\dfrac{5^3}{9^3}}=\dfrac{5}{9}[/tex]
Smaller areaThe area of the smaller figure is found from ...
[tex]\dfrac{A}{324\text{ m}^2}=\left(\dfrac{5}{9}\right)^2=\dfrac{25}{81}\\\\A=(324\text{ m}^2)\cdot\dfrac{25}{81}=\boxed{100\text{ m}^2}[/tex]
The surface area of the smaller solid is 100 square meters.

An ATM personal identification number (PIN) consists of a four-digit sequence. According to a representative at the bank, there are in fact restrictions on the choice of digits. It is prohibited to have any sequence start with 19 (birth years are too easy to guess). How many possible PINs are there with this restriction
The number of combinations of pins that can generated without using 19 in beginning are 3645 pins.
Given ten numbers from 0 to 9 and we are require to generate pins such that 19 will not come in beginning.
Total numbers=10
Combinations are the arrangement of numbers, variables, alphabets, etc. to form another numbers or word. In this problem we have to use combinations because there will be many combinations made from 10 numbers to form a 4 digit pin.
[tex]C=n!/r!(n-r)![/tex]
Combination: When 19 is not in beginning, we have to use 2 numbers in the beginning other than 19 so we can use all 9 numbers on thousandths place other than 1 and all the 9 numbers on hundredth place other than 9 and rest 2 places can be filled with any number from all 10 numbers so the combinations will be [tex]9 C_{1}*9C_{1}* 10C_{2}[/tex]=9*9*45=3645 pins.
Hence we can make 3645 pins of ATM from 10 numbers not starting with 19.

Answer:
232.28°
Step-by-step explanation:
Using N = 0 degrees
Arctan ( 12.8 / 9.9) = 52.28 degrees ( this A to C )
C to A would be 232.28 ° ( just add 180 degrees)

Answer:
about 94.41°
Step-by-step explanation:
The Law of Cosines can be used to find an angle in a triangle with three sides given.
SetupThe law of cosines relation generally relates the side opposite the angle to the other measures in the triangle:
r² = p² +q² -2pq·cos(R)
SolutionWe want to find the measure of angle R, so we solve the equation for that:
2pq·cos(R) = p² +q² -r² . . . . . . add 2pq·cos(R)-r²
cos(R) = (p² +q² -r²)/(2pq) . . . . divide by the coefficient of the cosine
We can fill in the given side lengths at this point:
cos(R) = (13² +10² -17²)/(2·13·10) = -20/260 = -1/13
Then the angle can be found using the arccos function:
R = arccos(-1/13) ≈ 94.41°
The measure of angle R is about 94.41°.

Additional comment
When you have done a few of these, you recognize that the angle opposite side 'c' is ...
C = arccos((a² +b² -c²)/(2ab))
A calculator can make short work of this. The second attachment shows the evaluation of this expression with a=10, b=13, c=17. The calculator angle mode is set to degrees. The arccos function is the 2ND function of the Cos key.
