Note (For 1st Question) :
• Figure is provided in the Attachment[tex].[/tex]
Answer:
1)
y = 45° (converse of alternate interior angle theorem)
z = 45° (alternate interior angle theorem)
k = 135° (exterior angle theorem)
2)
Cos θ + Sin θ = √2 Cos θ
(Cos θ + Sin θ)² = (√2 Cos θ)²
(Exponential property of equality)
Cos² θ + Sin² θ + 2 (Cos θ • Sin θ) = (√2 Cos θ)²
(Distributive property)
1 + 2(Cos θ • Sin θ) = (√2 Cos θ)²
(Definition of the pythagorean identity).
This identity is true because, if a² + b² = c². The triangle must be a right triangle, and a right triangle always has a 90° angle tangent to the triangle, and the tangent of 90° is 1, cos applied to the adjacent over hypotenuse, and sin applies to the opposite over hypotenuse, so this identity must work).
1 + 2(Cos θ • Sin θ) = 2 Cos² θ
(definition of an exponent)
1 + 2(Cos θ • Sin θ) – 1 = 2 Cos² θ – 1
(subtraction property of equality)
2(Cos θ • Sin θ) = 2 Cos² θ – 1
2(Sin θ • Cos θ) = 2 Cos² θ – 1
(Associative property of multiplication ; the input for both functions are θ so this rule works, this is an exception)
Sin (2x) = 2 Cos² θ – 1
(double angled identity of 2 sine and cos)
Ted ran 2/5 in 3/4 hour. What is his speed?
Answer:
8/15
Step-by-step explanation:
d=rt (distance = rate x time)
2/5=r(3/4)
Divide 3/4 on both sides.
r = 8/15

Truetone Music company sold 192,000 alternative music downloads. This represents 64% of their total sales. How
many total downloads did Truetone selt?
Answer:
The total downloads is 300000
Step-by-step explanation:
Given
Represent the total downloads with D.
[tex]\% = 64\%[/tex]
[tex]Sales = 192000[/tex]
Required
Determine the value of D
We understand that 64% of D = sales.
In other words;
[tex]64\% * D = 192000.[/tex]
Convert % to decimal
[tex]0.64 * D = 192000.[/tex]
Make D the subject
[tex]D = 192000/0.64[/tex]
[tex]D = 300000[/tex]
Hence, the total downloads is 300000
What is the rise over run if the slope is (-2/3)?
Step-by-step explanation:
rise: any number in the multiple of 2
run: any number in the multiple of 3
WITH
a line sloping downwards
Topic: coordinate geometry
If you like to venture further, do check out my insta (learntionary) where I regularly post useful math tips! Thank you!
Answer:
[tex]Slope=\frac{Rise}{Run}=\frac{-2}{3}[/tex]
The rise is -2 and run is 3
Step-by-step explanation:
We need to find rise over run if the slope is (-2/3).
The formula of slope is: [tex]Slope=\frac{Rise}{Run}[/tex]
So in the given slope: [tex]Slope=\frac{-2}{3}[/tex]
The rise is : -2 and run is 3 because if we compare the formula of slope with the slope given we can simply find rise over run
[tex]Slope=\frac{Rise}{Run}=\frac{-2}{3}[/tex]
3(p - 29) - 4(2p - 39 - 5)
expand and simplify
Answer:
-5p+99
Step-by-step explanation:
Original Equation;
3(p - 29) - 4(2p - 39 -5)
★First Step: Multiply the number 3 by p and -29 which is in the first term so it's going to be;
3 multiplied by p and 3 multiplied by -29
3p - 87
★Second step: Add the -39 and -5 which is going to give you -44 because - + - is = -
-44
★Third step: Multiply -4 by 2p and -44 so it's going to be;
-4×2p=-8p and -4×-44=176 we have positive 176 because - × - = +
★Fourth Step: Remove brackets
So it's going to be;
3p - 87 -8p +176
★Then you combine like terms
3p - 8p - 87 +176
-5p + 99
3(p-29)-4(2p-39-5)
3p-87-4(2p-44)
3p-87-8p+176
3p-8p-87+176
-5p+99

Determine the point that is 3/4 the distance from the endpoint (−6,−16)(−6,−16) of the segment with endpoints (34,2)(34,2) and (−6,−16)(−6,−16).
what, pls explain cus there is other questions similar to this
Answer:
The location of the point that is 3/4 the distance from [tex]A(x,y)[/tex] is [tex]C(x,y) = (24, -2.5)[/tex].
Step-by-step explanation:
Let [tex]A(x,y) = (-6,-16)[/tex] and [tex]B(x,y) = (34,2)[/tex] the endpoints of the segment, we can determine the location of the point that is 3/4 the distance from [tex]A(x,y)[/tex] by the following vector equation:
[tex]C(x,y) = A(x,y) + \frac{3}{4}\cdot (B(x,y)-A(x,y))[/tex] (1)
If we know that [tex]A(x,y) = (-6,-16)[/tex] and [tex]B(x,y) = (34,2)[/tex], the location of [tex]C(x,y)[/tex] is:
[tex]C(x,y) = (-6,-16)+\frac{3}{4}\cdot [(34,2)-(-6,-16)][/tex]
[tex]C(x,y) = (-6,-16)+\frac{3}{4}\cdot (40,18)[/tex]
[tex]C(x,y) = (24, -2.5)[/tex]
The location of the point that is 3/4 the distance from [tex]A(x,y)[/tex] is [tex]C(x,y) = (24, -2.5)[/tex].

Question # 19
Revisit
On a certain day six passengers from cities - Alpha, Beta, Delta, Gamma, Kappa, and Lambda -
boarded a train starting from town Theta and with the final stop at city Meritland. The following facts
are known about these six passengers
1. The persons from Delta and Alpha are less than 36 years of age.
2. Zane, the youngest of all is a scientist
3. The oldest person is from Gamma and his/her profession is the same as that of the person who
got down at station X.
4. The
persons from Beta, Alpha. Lambda, and Kappa got down at four different stations. The
eldest among these four got down at station Y and the youngest at station Z. The person who
got down at Meritland is older than the person who got down at station X
5. The
pilot from Beta is older than the pilot from Apha.
6. While arranging the managers in increasing orden of age lit was observed that the middle person
is as old as the pilot from Aloha,
7. Yahu, who got down at station is less than 34 years old.
8. The manager from Delta is found ears older than the silvears old scientist
who is not from
Kappa
Which of the following options is true
Answer:
The correct answer is E. The person who got down at Meritland is older than Yahu, who in turn is older than the person from Lambda.
Step-by-step explanation:
We can conclude that there are three managers, two pilots, and one scientist from the information we're given. Since the youngest among the passengers is Zane, a scientist, his age must be 31. The passengers from Beta and Alpha are pilots, whereas the people from Gamma, Delta, and Kappa are all managers. This means that the passenger who is the scientist must be from Lambda. The passenger who got down at Station X is a manager and is under 34 years old.
The passengers from Delta and Alpha are 35 years old. The person from Beta got down at Station Y, while the person from Lambda got down at Station Z. Here’s the final distribution in the attachment:

find the slope of the line that contains the points (-6, 4) and (2, -8)
Answer:
slope = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 4) and (x₂, y₂ ) = (2, - 8)
m = [tex]\frac{-8-4}{2+6}[/tex] = [tex]\frac{-12}{8}[/tex] = - [tex]\frac{3}{2}[/tex]
