x = ±π/6 + πn, ±11π/12 + πn, where n is an integers are solutions of the equation cos²x = sin²x + 1/2
To solve the equation cos²x = sin²x + 1/2, we can use the trigonometric identity sin²x + cos²x = 1.
Rearranging the equation, we have:
cos²x - sin²x = 1/2
Using the identity cos²x - sin²x = cos(2x), we can rewrite the equation as:
cos(2x) = 1/2
The solutions to this equation can be found by taking the inverse cosine (or arccosine) of both sides:
2x = ±π/3 + 2πn, ±11π/6 + 2πn, where n is an integer
Dividing both sides by 2, we get:
x = ±π/6 + πn, ±11π/12 + πn, where n is an integers

find the bearing of a from b
find the bearing of b from a
Answer:
130° and 310°
Step-by-step explanation:
the bearing of A from B is the measure of the clockwise angle from a north line at B to A
the angle at B and A are same- side interior angles and sum to 180°
angle at B = 180° - 50° = 130°
the bearing of A from B is then 130°
the bearing of B from A is the measure of the clockwise angle from the north line at A to B
the complete angle about A = 360° then clockwise angle from north line at A to B is
360° - 50° = 310°
the bearing of B from A is 310°

Patient’s wt: 60 lb Medication order: 0.5 mg/kg Stock medication: 10 mg/mL
1. The weight of the patient in kilograms is 27.216 kg. (60 lb * 0.4536 kg/lb = 27.216 kg)
2. The total dosage of medication required for the patient is 13.608 mg. [tex](0.5 mg/kg \times 27.216 kg = 13.608 mg)[/tex]
3. The patient should be administered 1.3608 mL of the stock medication. (13.608 mg / 10 mg/mL = 1.3608 mL)
To calculate the necessary values based on the given information, let's follow the steps below:
Determine the weight of the patient in kilograms:
Given that the patient weighs 60 lb, we can convert this to kilograms using the conversion factor of 1 lb = 0.4536 kg.
Weight (in kg)[tex]= 60 lb \times 0.4536 kg/lb = 27.216 kg.[/tex]
Calculate the total dosage of medication required for the patient:
The medication order is 0.5 mg/kg, and the patient weighs 27.216 kg.
Total dosage [tex]= 0.5 mg/kg \times 27.216 kg = 13.608 mg.[/tex]
Determine the amount of stock medication required in milliliters (mL):
The stock medication is available in a concentration of 10 mg/mL.
To find the volume required, we need to divide the total dosage by the concentration of the stock medication.
Volume (in mL) = Total dosage (in mg) / Concentration (in mg/mL) = 13.608 mg / 10 mg/mL = 1.3608 mL.
Therefore, based on the given information, the weight of the patient is 27.216 kilograms, the total dosage of medication required is 13.608 milligrams, and 1.3608 milliliters of the stock medication should be administered to the patient.

in a certain country people own a total of about 356 million fish, cats, and dogs as pets. The number of fish owned is 12 million more than the total number of cats and dogs owned, and 12 million more cats are owned than dogs. how many of each type of pet do people in this country own?
People in this country own approximately 111 million dogs, 123 million cats, and 258 million fish as pets.
Let's solve the problem step by step to determine how many of each type of pet people in this country own.
Let's assume the number of dogs as D.
According to the information given, the number of cats would be D + 12 million since there are 12 million more cats than dogs.
The number of fish would be the sum of the number of cats and dogs plus 12 million, as there are 12 million more fish than the total number of cats and dogs combined.
So, the equation representing the total number of pets is:
D + (D + 12 million) + (D + 12 million) = 356 million
Simplifying the equation, we have:
3D + 24 million = 356 million
Subtracting 24 million from both sides, we get:
3D = 332 million
Dividing both sides by 3, we find:
D = 110.67 million
Since the number of pets cannot be in fractions, we can round D to the nearest whole number. In this case, D ≈ 111 million.
Now, we can calculate the number of cats:
Cats = D + 12 million
= 111 million + 12 million
= 123 million
And the number of fish:
Fish = (D + Cats) + 12 million
= (111 million + 123 million) + 12 million
= 246 million + 12 million
= 258 million

jazmine made 3 1/3 cups of jam. she will separate the jam into jars that each hold 2/5 cup.
Answer:
To find out how many jars Jazmine can fill with her 3 1/3 cups of jam, we need to divide the total amount of jam by the amount of jam that each jar can hold.
First, we need to convert 3 1/3 cups into an improper fraction:
3 + 1/3 = (3 x 3 + 1) / 3 = 10/3
So, Jazmine has 10/3 cups of jam.
Next, we need to convert the jar size of 2/5 cup into a fraction with the same denominator as 10/3:
2/5 = 6/15
Now we can divide the total amount of jam by the amount of jam that each jar can hold:
(10/3) ÷ (6/15)
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction:
(10/3) x (15/6)
Simplifying:
(10/3) x (5/2) = (50/6)
So Jazmine can fill (50/6) jars with her 3 1/3 cups of jam.
This is an improper fraction, so we can convert it to a mixed number:
(50/6) = 8 2/6 = 8 1/3
Therefore, Jazmine can fill 8 and 1/3 jars with her 3 1/3 cups of jam.

The correct answer is:
B. cosθ = √5/3 and tanθ = 2/√5
C. cosθ = -√5/3 and tanθ = 2/√5
To solve this question, we can use the given information that sinθ = 2/3 and determine the values of the other trigonometric functions based on that.
Recall the trigonometric identity: sin^2θ + cos^2θ = 1
Since sinθ = 2/3, we can substitute this value into the identity and solve for cosθ:
(2/3)^2 + cos^2θ = 1
4/9 + cos^2θ = 1
cos^2θ = 1 - 4/9
cos^2θ = 5/9
Taking the square root of both sides, we get:
cosθ = ±√(5/9) = ±(√5/3)
Now, let's analyze the given options:
A. secθ = 3/√5 and tanθ = 2/√5
B. cosθ = √5/3 and tanθ = 2/√5
C. cosθ = -√5/3 and tanθ = 2/√5

Given the trigonometry identity below:
cos3∅=cos²∅-3cos∅sin²∅
We are to prove that both sides of the equation are equal.
cos 3θ = cos(2θ + θ)
Using the double angle formula for cosine, we can expand the first term:
cos(2θ + θ) = cos2θ cos θ - sin2θ sinθ
Since cos2θ = cos²θ - sin²θ
cos(2θ + θ) = cos²θ - sin²θ - 2cosθsinθsinθ
cos(2θ + θ) = cos²θ - sin²θ - 2cosθsin²θ
On simplifying, we can see that;
cos3θ =cos(2θ + θ) = cos²θ - 3cosθsin²θ (Proved)

17. What is the value of y in ADEF?
D
7y +14
F
jo
9y+2
DE
Answer:
y = 6
Step-by-step explanation:
You want the value of y, given the sides of isosceles triangle DEF are marked as (7y +14) and (9y +2).
Isosceles triangleThe sides of an isosceles triangle are congruent, so we have ...
FD = FE
7y +14 = 9y +2
12 = 2y . . . . . . . . . . subtract 7y+2
6 = y . . . . . . . . . divide by 2
The value of y is 6.
__
Additional comment
We know this triangle is isosceles for a couple of reasons. One is that the altitude is a perpendicular bisector of the base. Another is that the two smaller triangles are congruent by the SAS (or LL) postulate, making FD = FE by CPCTC.

Compute probability of rolling two dice that have a sum of 7. Write the probability as a simplified fraction.
Thank you!!!
The probability of rolling two dice that have a sum of 7 is: 1/6.
What is the probability?When rolling two dice each die will have 6 possible outcomes
Total number of possible outcomes= 6 * 6
Total number of possible outcomes = 36
Now let's roll a sum of 7 dice to determine the amount of favourable results. There are 6 various ways that the number 7 may be combined, and they are as follows:
(1, 6), (2, 5), (3, 4), (4, 3), (5, 2) and (6, 1)
The number of favorable outcomes is 6.
Let find the probability of rolling two dice that have a sum of 7 :
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Probability = 6 / 36
Probability = 1 / 6
Therefore the probability is 1/6.
