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

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]

In the problem 3/4 • N=1, n must be

Answers

3/4 x n=1......n equals 4/3.

In order for n to equal 1 you have to find a number that will make 3/4 a whole number after you multiply it. Usually in problems like these the answer is usually the fraction but flipped around. So 3/4 and 4/3....when you multiply the    numerators you get 12 and when you multiply the denominator you get 12 so 12/12, which equals 1. hope that makes sense.

The answer would be 4/3 because it’s the reciprocal of it. And it would be 1

expand and simplify​

Answers

Answer: -7 - 188
I think this is the answer

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

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

On a certain day six passengers from cities - Alpha, Beta, Delta, Gamma, Kappa, and Lambda -

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​

Answers

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:

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]
