In trigonometry, both sine and cosine are negative in the third quadrant of the coordinate plane, as both the x and y coordinates are negative in this quadrant.
Explanation:In the context of trigonometry, on the coordinate plane, sine and cosine are both negative in the third quadrant. The sine function represents the y-coordinate and the cosine function represents the x-coordinate of a point on the unit circle. Hence, in the third quadrant, where both x and y are negative, both sine and cosine are negative as well. This is a basic idea from trigonometry and is commonly referred to as the rule 'All Students Take Calculus', which helps to remember the sign of sine, cosine and tangent in each quadrant. A- all (Quadrant I, all are positive), S - Sine (Quadrant II, only sine is positive), T - Tangent (Quadrant III, only tangent is positive), C - Cosine (Quadrant IV, only cosine is positive). Therefore in the III quadrant, both sine and cosine are negative as only tangent (ratio of sine to cosine) is positive.

A pedestal on which a statue is raised on is a rectangular concrete solid measuring nine
feet long, nine feet wide, and six inches high. How much is the cost of the concrete in the
pedestal, if concrete costs $70 per cubic yard?
Answer:
The cost of the rectangular concrete solid is $104.87Step-by-step explanation:
If the pedestal on which a statue is raised on is a rectangular concrete solid measuring nine feet long, nine feet wide, and six inches high, the volume of the rectangular concrete solid will be expressed as shown;
Volume of the rectangular concrete solid = Length * Width * Height
Given Length = 9ft, Width = 9ft and Height = 6inches
Converting all the units to yards
Given 1ft = 0.333yard
Length = 9 * 0.333 = 2.997yards
Width = 9* 0.333 = 2.997yards
Also given 1inch = 0.0278yard
Height = 6 * 0.0278yards = 0.1668yards
Volume of rectangular concrete solid in cubic yards = 2.997*2.997*0.1668
Volume of rectangular concrete solid in cubic yards = 1.4982cubic yards
If concrete costs $70 per cubic yard, the cost of the rectangular concrete solid will be 1.4982 *$70 = $104.87
Cost to store: $75
Percent of Markup:
Selling price: $112.50
Answer:
15%
Step-by-step explanation:
pretty sure thats right
Final answer:
The student's question involves a business math concept of calculating the percent markup from the cost and selling price, resulting in a 50% markup for this example.
Explanation:
The question involves calculating the percent markup based on the cost to store an item and its selling price.
To find the percent of markup, you subtract the cost to store from the selling price and then divide by the cost to store.
Finally, multiply by 100 to get the percentage.
For example, if an item costs $75 to store and sells for $112.50, the markup is ($112.50 - $75) / $75 = 0.50, or 50%.
This is an example of a basic markup calculation commonly covered in business and economics classes in high school.
A number m increased by 5 is 7.
Answer:

Line segment ON is perpendicular to line segment ML.
Circle O is shown. Line segments M O, N O, and L O are radii. Lines are drawn to connects points M and N and points N and L to form chords. A line is drawn from point M to point L and intersects line O N at point P. The length of O M is 13 and the length of P N is 8. Angle O P L is a right angle.
What is the length of chord ML?
20 units
24 units
26 units
30 units
Answer:
B. 24 units
Step-by-step explanation:
Each triangle has 13 as the hypotenuse and 8 as a leg length; the lengths carry over.
The longer leg length (MP & PL) is 12 from the pythagorean theorem.
13^2 - 8^2 = 12^2.
MP + ML = PL, so 12 + 12 = 24.

Find the equation of the hyperbola centered at the origin that satisfies the given conditions: x-intercepts = +,-4 and asymptote at y=3/4x
Answer:
The equation of the hyperbola is presented as follows;
[tex]\frac{x^2}{16} - \frac{y^2}{9} =1[/tex]
Step-by-step explanation:
Here we have the standard equation of an hyperbola given as follows;
[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} =1[/tex]
Where:
a = x intercept
The asymptote is ±(b/a)x
Since the intercept, a is ± 4, the vertices are (-4, 0) and (4, 0)
We are given the asymptote as y = 3/4x, therefore, since the genral form of the asymptote is ±(b/a)x, comparing, we have;
±(b/a)x ≡ 3/4x
We have a = ±4, therefore, b = 3
Hence the equation of the hyperbola is found by putting in the values of a and b in the general form as follows;
[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} =1 \Rightarrow \frac{x^2}{4^2} - \frac{y^2}{3^2} =1[/tex]
The equation of the hyperbola = x²/16 - y²/9 = 1.

Amanda has a ribbon that is 6 feet long. She wants to cut it into 12 equal pieces. How long will each piece be? Write the steps, in order, you would take to solve the problem. * 2 points Your answer
Answer:
Each of the pieces will be 0.5 feet long
Step-by-step explanation:
In this question, we are asked to calculate the individual length Anita will cut a ribbon 6 feet long into to ensure that each of the piece has the same length.
To calculate this, since we don not know what length each of the piece would be, we can say let the length of each of the pieces be x feet
Now, we know that there are 12 pieces that are equal in length. The length of all these 12 pieces would be 12 * x = 12x feet
Now what do we know again?
We also know that these 12x feet equals a total of 6 feet
mathematically therefore;
12x = 6
x = 6/12
x = 0.5 feet
Answer: Each piece will be 1/2 feet long.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given.
We simply have to divide the length of the ribbon (6) by the number of pieces that she wants to cut (12).
Mathematically speaking:
6 /12 = 1/2
In conclusion, each piece will be 1/2 feet long.

Jordan went to the store to buy a bicycle that was advertised for $50. When he arrived, he learned that the model he wanted was sold out, but there was another bicycle available that cost 15% more. How much did the available bicycle cost before taxes? $7.50 $57.50 $65.00 $15.00
Answer: 57.50
Step-by-step explanation:
50*.15=7.50
50+7.5=57.50
B - $57.50
Step-by-step explanation:
To find the cost of the available bicycle before taxes, we need to add another 15% to the original $50. To do that, all you do is multiply $50 by 15%, and then re-add the $50. Work is shown below:
First, change 15% into a decimal:
15% -> 15/100 -> 0.15
Next, lets find the cost of the available bicycle:
x = 50 (0.15)
x = 7.5
Now add the $50 back 7.5:
50 + 7.5 = 75.50
So your answer is B = $57.50
James had a peach that was 98 mm in diameter. One day he watered it with a magical solution, and it grew to 188,869 mm
in diameter.
Approximately how many times as large did the diameter of the peach become after James watered it?
To determine how many times larger the peach got, you will divide the new diameter by the original diameter length.
188869/98 = 1927.2
The new diameter is approximately 1927 times longer.
To convert this to scientific notation, move the decimal point from the end (on the right) to between the 1 and the 9 to get 1.927.
Then count the number of decimal places you moved to get there, because this represents how many groups of 10 you adjusted your place value by and then becomes your exponent in scientific notation.
1.927 x 10^3 times is the answer in scientific notation.
Answer:

20. Helen and Carla live in states that have
different sales tax rates. They each bought
a new bicycle. Helen paid $14 for a 5.6%
sales tax on her bicycle. Carla paid $12 for
a 4.8% sales tax on her bicycle. Who paid
more for their bicycle, not including sales
tax?
Answer: Helen paid $250 for the bike
Carla paid $250 for the bike.
They both paid the same amount
Step-by-step explanation:
Final answer:
By calculating the pre-tax prices of the bicycles using the provided sales tax amounts and rates, we determine that both Helen and Carla's bicycles cost $250 before tax, meaning neither paid more for their bicycle excluding the sales tax.
Explanation:
To determine who paid more for their bicycle excluding the sales tax, we need to calculate the pre-tax price of each bicycle using the sales tax amounts given. This requires us to work backwards from the sales tax paid to the original cost of the item.
For Helen, we know that the sales tax was $14, and the rate was 5.6%. We find the pre-tax price by dividing the sales tax paid by the sales tax rate (converted into decimal form):
Pre-tax price for Helen = $14 / 0.056 = $250
For Carla, the sales tax was $12, and the rate was 4.8%. The pre-tax price calculation is similar:
Pre-tax price for Carla = $12 / 0.048 = $250
Since both pre-tax prices are equal, neither Helen nor Carla paid more for their bicycle when we do not include the sales tax.

What is the slope and x-intercept of y=2x+1?
Answer:
slope: 2
x-intercept = -1/2
Step-by-step explanation:
The equation is in y = mx + b form. m = slope. The slop is equal to 2.
To find the x-intercept set y equal to 0 and solve for x.
0 = 2x + 1
-1 = 2x
x = -1/2
Answer:
slope= 2
x intercept=-0.5 or -1/2
Step-by-step explanation:
y= mx+b
m is the slope, therefore 2 is the slope of the equation.
X-intercept
substitute 0 to y
0=2x + 1
Subtract 1 from both sides
0-1=2x+1-1
-1=2x
Divide both sides by 2
-1/2=2x/2
x=-1/2 or -0.5

The price of 8 citrons and 9 fragrant wood apples is 145 units. The price of 9 citrons and 8 fragrant wood apples is 144 units. Find the price of a citron and the price of a wood apple.
Answer:
The price of a citron is 8 and the price of a wood apple is 9
Step-by-step explanation:
First of all we make two equations that represents the problem
c = citrons price
w = wood apples price
8c + 9w = 145
9c + 8w = 144
we clear c in the first equation
8c + 9f = 145
8c= 145 - 9w
c = (145 - 9w) /8
c = 145/8 - 9w/8
we replace c by (145/8 - 9w/8) in the second equation and solve
9(145/8 - 9w/8) + 8w = 144
163.125 - 10.125w + 8w = 144
163.125 - 144 = 10.125w - 8w
19.125 = 2.125w
19.125/2.125 = w
9 = f
now we replace w in the first equation
8c + 9w = 145
8c + 9(9) = 145
8c + 81 = 145
8c = 145 - 81
8c = 64
c = 64 / 8
c = 8
The price of a citron is 8 and the price of a wood apple is 9
