Determine the general solution of 6 sinx+7cosx-3=0​

Please Help. Prove The Following Identity: Sin [ (90 +x). Sin (x-180) -cos (180+x)/ Cosx] -2 Sin 0 =

Answers

Answer 1

Using trigonometric identities;

a. We are able to proof that [sin(90° + θ)sin²( θ - 180°) - cos θ(180° +  θ)] / [cos θ - 2sin² θ] = cos 2θ

b. The general solution is:

x = cos⁻¹(-1/3) + 2kπ and x = 2π - cos⁻¹(-1/3) + 2kπ, where k is an integer.

What is the proof of the trigonometric identity?

a. To prove the identity:

[sin(90° + θ)sin²( θ - 180°) - cos θ(180° +  θ)] / [cos θ - 2sin² θ] = cos 2θ

First, let's simplify the left-hand side (LHS) of the equation:

[sin(90° + θ)sin²( θ - 180°) - cos θ(180° +  θ)] / [cos θ - 2sin² θ]

= [cos θ sin²( θ - 180°) - cos θ(180° +  θ)] / [cos θ - 2sin² θ]

= [cos θ sin²( θ - 180°) - cos θ(180° +  θ)] / cos θ [1 - 2sin² θ / cos θ]

= [cos θ sin²( θ - 180°) - cos θ(180° +  θ)] / cos θ [1 - 2sin² θ / cos θ]

Next, simplify each term individually:

cos θ sin²( θ - 180°) = cos θ (-sin² θ) = -cos θ sin² θ

cos θ(180° +  θ) = cos θ * 180° + cos θ * θ = 180° cos θ + θ cos θ

2sin² θ / cos θ = 2(sin θ / cos θ)² = 2tan² θ

Substituting these simplified terms back into the equation:

[-cos θ sin² θ - (180° cos θ + θ cos θ)] / cos θ [1 - 2tan² θ]

= [-cos θ sin² θ - 180° cos θ - θ cos θ] / cos θ [1 - 2tan² θ]

= -cos θ [sin² θ + 180° + θ] / cos θ [1 - 2tan² θ]

= -(sin² θ + 180° + θ) / [1 - 2tan² θ]

Now, we can use trigonometric identities to simplify further:

sin² θ + cos² θ = 1

1 - cos² θ = sin² θ

1 - sin² θ = cos² θ

tan² θ + 1 = sec² θ

Using these identities, we can rewrite the expression as:

-(sin² θ + 180° + θ) / [1 - 2tan² θ]

= -(1 - cos² θ + 180° + θ) / [1 - 2tan² θ]

= -(1 - (1 - sin² θ) + 180° + θ) / [1 - 2tan² θ]

= -(-sin² θ + 180° + θ) / [1 - 2tan² θ]

= (sin² θ - 180° - θ) / [1 - 2tan² θ]

= cos 2θ / [1 - 2tan² θ]

Hence, we have shown that the left-hand side (LHS) of the equation is equal to cos 2θ, which verifies the identity.

b. To determine the general solution of 6sin²x +

7cosx - 3 = 0:

Start by rewriting the equation using trigonometric identities:

6(1 - cos²x) + 7cosx - 3 = 0

6 - 6cos²x + 7cosx - 3 = 0

-6cos²x + 7cosx + 3 = 0

Now, let's solve this quadratic equation for cosx:

Multiply the equation by -1 to make the leading coefficient positive:

6cos²x - 7cosx - 3 = 0

Using factoring or the quadratic formula, we can solve for cosx. However, since the coefficients do not easily factor, we will use the quadratic formula:

cosx = (-b ± √(b² - 4ac)) / (2a)

Plugging in the values, we have:

cosx = (-(-7) ± √((-7)² - 4(6)(-3))) / (2(6))

cosx = (7 ± √(49 + 72)) / 12

cosx = (7 ± √121) / 12

cosx = (7 ± 11) / 12

Now we have two possible solutions for cosx:

1. cosx = (7 + 11) / 12 = 18 / 12 = 3 / 2 (not possible since -1 ≤ cosx ≤ 1)

2. cosx = (7 - 11) / 12 = -4 / 12 = -1 / 3

Since the cosine function is positive in the first and fourth quadrants, and the given equation involves cosine, we are interested in solutions in those quadrants.

In the first quadrant, x can be determined using the inverse cosine function:

x = cos⁻¹(-1/3)

In the fourth quadrant, x can be determined using the inverse cosine function and the fact that cosine is periodic:

x = 2π - cos⁻¹(-1/3)

Therefore, the general solution is:

x = cos⁻¹(-1/3) + 2kπ and x = 2π - cos⁻¹(-1/3) + 2kπ, where k is an integer.

Matt's four cousins are coming to visit. There are four identical rooms that they can stay in. If any number of the cousins can stay in one room, how many different ways are there to put the cousins in the rooms

Answers

The total number of different ways there are to put the cousins in the rooms is;  15

How to use probability combinations?

When we count the number of cousins staying in each room, it means that the possibilities are as follows; (4,0,0,0), (3,1,0,0), (2,2,0,0), (2,1,1,0), (1,1,1,1).

1) (4,0,0,0): This means that there is only 1 way to put all the cousins in the same room due to the fact that the rooms are identical.

2) (3,1,0,0): This means that there are 4 ways to choose which cousin will be in a different room than the others.

3) (2,2,0,0): This means that there are 3 ways to choose which of the other cousins will also stay in that room, and then the other two are automatically in the other room.

4) (2,1,1,0): This means that the number of ways to choose which cousins stay in the same room is; 4C2 = 6

5) (1,1,1,1): This means that there is only one way for all the cousins to the total number of possible arrangements is;

1 + 4 + 3 + 6 + 1 = 15each stay in a different room.

Answers

The total amount that roland paid for the ticket is $27.60

Given that the price of an all-access ticket to the fair is $42.99 before tax. Roland bought the all-access ticket for 40% off.

We need to calculate the total amount paid by the roland

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100

The price after 40% off -

= 42.99*60% = $25.794

Sales tax on 25.794

= 25.794*7% = $1.80558

Total amount Paid for the ticket

= 1.80558 + 25.794 = $27.59958

= $27.60

Answers

The larger number is 32 and the smaller number is 28 given that one number is 4 more than another and their sum is 60. This can be obtained by forming algebraic equation and finding

Calculate the value of the numbers:

Given that one number is 4 more than another,

⇒x = y + 4              (equation (1))

Their sum is 60,

⇒x + y = 60

y + 4 + y = 60      (From (1))

2y + 4 = 60

2y = 56 ⇒ y = 28

x = y + 4 = 28 + 4 = 32

Answers

Answer:   y = -x + 2

Step-by-step explanation:

Point slope form is y - y = m(x - x)

m = the slope of the line

Slope-intercept form is y = mx + b

m = the slope of the line

b = y-intercept

So because the - is in the m spot in the point-slope form, that means that is the slope of the line meaning it will also be in the m spot in slope-intercept form. The y-intercept of the line is found when x is 0.  When we look at the two coordinates provided you can see that one of them shows when x is 0.  We see that when x is 0, y is 2  which means that the y-intercept is 2.

So when you put the 2 in place of b,  you get   y = -x + 2

A recipe for fruit punch calls for 333 liters of orange juice and 222 liters of pineapple juice. Jo creates a drink by mixing 444 liters of orange juice with 333 liters of pineapple juice. Which recipe will have the stronger pineapple taste

Answers

The jo's drink have stronger pineapple taste.

Given that fruit punch calls for 333 liters of orange juice and 222 liters of pineapple juice and Jo creates a drink by mixing 444 liters of orange juice with 333 liters of pineapple juice.

In the Recipe for fruit punch calls

The Number of liters of orange juice = 333.

The Number of liters of pineapple juice = 222.

Thus, Total number of liters of juice = 222+333= 555 liters

Now, % of pineapple juice in fruit punch is

P₁=(222/555)×100

P₁=0.4×100

P₁=40%

Further, % of orange juice in fruit punch is

O₁=(333/555)×100

O₁=0.6×100

O₁=60%

In Jo's drink

The Number of liters of orange juice = 444.

The Number of liters of pineapple juice = 333.

Thus, Total number of liters of juice = 444+333= 777 liters

Now, % of pineapple juice in jo's drink is

P₂=(333/777)×100

P₂=0.43×100

P₂=43%

Further, % of orange juice in jo's drink is

O₂=(444/777)×100

O₂=0.57×100

O₂=57%

Hence, the taste of both drinks was not the same, jo's drink will have a stronger pineapple taste and jo's drink will have a lesser orange taste.

3. Given diameter (D) = 60

Radius = 1/2 D
= 30
Circumference = πD
= 188.49555921539
Area =
pi (D/2) ^2
= 2827.4333882308

4. Given diameter (D) = 1.8

Radius =
D/2
= 0.9
Circumference = πD
= 5.6548667764616
Area =
π( D/2 ) ^2
= 2.5446900494077

Hi! I’ve tried at this question many times and still do not understand why the answer isn’t B but A. Please explain as best as you can! Thanks! (The question is below in the picture)

Please look closely at the attached images where I gave graphed these points.

I hope this helps. Please let me know if you have questions.

The temperature, t, in Burrtown starts at 32°F at midnight, when h = 0. For the
next few hours, the temperature drops 2 degrees every hour.
Which equation represents the temperature, t, at hour h?
OA. t= 2h+32
B. t= -2h+ 32
C. t = 32h-₂
OD. t= -32h+2

Answers

You would multiply the change per hour by number of hours to get -2h

That would be added to the starting temperature.

Answer: B, t = -2h + 32

Answer: The answer is B

Step-by-step explanation:

The question says it drops ( which means subtraction) by 2 degrees every hour, so -2h
