Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

x = 12/5Step-by-step explanation:
√x² + 49 = x + 5
Square both sides
(√x² + 49)² = ( x + 5)²
x² + 49 = x² + 10x + 25

10x = 49 - 25
10x = 24

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x
so let’s plug in from your table.

(you could also do 1-0 divided by 0-(-7))
-1/-7 which equals 1/7
so, your slope is 1/7

32 people will each drink a glass of lemonade. It takes 6 lemons to make one glass. If lemons are sold in bags of 10, how many bags should he buy?
Answers
Answer:
20 bags
Step-by-step explanation:
they should by 20 bags because 6 x 32 will equal how many lemons total you need. then you divide that number by 10.
Answer:
He should buy 20 bags of lemons.
Step-by-step explanation:
Okay, so the first step will be to see how many lemons we first need. We do this by multiplying the 32 people and the 6 lemons:
32 x 6 = 192 lemons
The next step is to find out how many bags we need. So, we know we have 192 lemons and each bag of lemons contain 10, so we need to divide 192 by 10.
192 divided by 10 = 19.2
Now, 19.2 isn't the answer because it is not a whole number. We can't buy a fraction of lemons. So, we need to buy 1 more extra bag to be able to have all 32 people be able to have some lemonade:
19 + 1 = 20 bags of lemons.

The expression 2x + 4x represents the cost of buying the same number of cases of spring water, sold for $2 per case, and sparkling water, sold for $4 per case. What expression can be used to express the total cost?
Answers
Answer: 2x + 4x = (2 + 4)x = 6x
Step-by-step explanation:
The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.
Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:
2x + 4x = (2 + 4)x = 6x
Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.
Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.

Sindy bought a pair of jeans with a price tag of $68.00. She paid 8% sales tax. How much sales tax did she pay and what was her final price including tax?
Answers
Answer:
Step-by-step explanation:
Sindy paid $5.44 in sales tax, and her total price was $73.44.
Sales Tax: 68 x .08= 5.44
Final Price: 68 + 5.44= 73.44
Answer:
To find sales tax, you need to find the percent of;
$68.00 * 8%
$68.00 * 0.08
= $5.44
$5.44 is the sales tax
Add the sales tax to the original amount:
$68.00 + $5.44 = $73.44
So the final price including tax is equal to $73.44.

The first option is correct, 12/30 and 25/30
Step-by-step explanation:
To get common denominators, you need to find the GFC (greatest common factor) of 5 and 6, which is 30. Then you would need to make the fractions equal the same as the original fractions, by multiplying.
2/5 = ?/30 <- you can see that 30 is 6 times more than 5. so this means you multiply 2 by 6 to get 12. 12/30
5/6 = ?/30 <- you can see that 30 is 5 times more than 6. so this means you multiply 5 by 5 to get 25. 25/30

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Step-by-step explanation:
B = 25 + .05M
20 minutes a day for 30 days = 600 minutes per month
A(600) = 40+.1(100) = $50
B(600) = 25 + .05(100) = $30
Plan B is less expensive
40+.1(M-500)= 25+.05M
40-25- .1(500) = .05-.1M
.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B
40+.1(200) = $60 under plan A
25+.05(700) = $60 under plan B
