By following these steps, you can use the unit circle to define the trigonometric functions of any angle.

Steps: Draw a unit circle,  place the angle, Identify the point of intersection, Define the trigonometric functions.

To use the unit circle to define the trigonometric functions of any angle, follow these steps:
1. Draw a unit circle: This is a circle with a radius of 1, centered at the origin (0, 0) of the coordinate plane.

2. Place the angle: Position the angle in standard position, which means that the initial side (starting side) of the angle is along the positive x-axis and the terminal side (ending side) is formed by rotating the initial side counterclockwise to a certain position.

3. Identify the point of intersection:

Determine the point where the terminal side of the angle intersects the unit circle.

This point will have coordinates (x, y).
4. Define the trigonometric functions:

Using the coordinates (x, y), define the six trigonometric functions as follows:
  - Sine (sin): sin(angle) = y
  - Cosine (cos): cos(angle) = x
  - Tangent (tan): tan(angle) = y/x
  - Cosecant (csc): csc(angle) = 1/y
  - Secant (sec): sec(angle) = 1/x
  - Cotangent (cot): cot(angle) = x/y.

Answer:

2) x = 3√5; y = 6;

3) x = 12√2; y = 12;

4) x = 45∘; y = 45∘;

5) x = 60∘; y = 30∘

Step-by-step explanation:

2) Use trigonometry:

[tex] \cos(60∘) = \frac{3}{y} [/tex]

Use the property of the proportion to find y:

[tex]y = \frac{3}{ \cos(60∘) } = \frac{3}{1} \div \frac{1}{2} = \frac{3}{1} \times \frac{2}{1} = 6[/tex]

Use the Pythagorean theorem to find x:

[tex] {x}^{2} = {y}^{2} + {3}^{2} = {6}^{2} + {3}^{2} = 36 + 9 = 45[/tex]

[tex]x > 0[/tex]

[tex]x = \sqrt{45} = 3 \sqrt{5} [/tex]

3) Use trigonometry:

[tex] \sin(45∘) = \frac{12}{x} [/tex]

Use the property of the proportion to find x:

[tex]x = \frac{12}{ \sin(45∘) } = \frac{12}{1} \div \frac{ \sqrt{2} }{2} = \frac{12}{1} \times \frac{2}{ \sqrt{2} } = 12 \sqrt{2} [/tex]

Use trigonometry:

[tex] \tan(45∘) = \frac{12}{y} [/tex]

Use the property of the proportion to find y:

[tex]y = \frac{12}{ \tan(45∘) } = \frac{12}{1} = 12[/tex]

4) Use trigonometry:

[tex] \tan(x∘) = \frac{3}{3} = 1[/tex]

x = 45∘

[tex] \tan(y∘) = \frac{3}{3} = 1[/tex]

y = 45∘

5) Use trigonometry:

[tex] \cos(x∘) = \frac{4}{8} = \frac{1}{2} = 0.5[/tex]

x = 60∘

What is a capacitor short answer?

A capacitor is a component used in electrical circuits to hold charges. The idea behind how a capacitor functions is that when an earthed conductor is moved close to a conductor, its capacitance increases noticeably.

                                      As a result, a capacitor contains two plates with equal and opposing charges that are spaced apart. Two conductors that are near to one another and are isolated from one another make up a capacitor, a device for storing electrical energy.

Supplementary angles are angles whose sum up to 180 degrees.

the recommended amount of mulch for the flower bed with a radius of 20 feet and a desired depth of 0.5 feet is approximately 628.3 cubic feet.

The given information about the vertex of the function does not appear to be relevant to the question about mulch for a flower bed. However, we can still solve the problem using the given radius of the flower bed.

The formula to find the recommended amount of mulch for a circular flower bed is:

Mulch = π * r^2 * d

Where r is the radius of the flower bed and d is the desired depth of the mulch.

Assuming a desired depth of 0.5 feet, we can plug in the given radius of 20 feet to the formula:

Mulch = π * (20 feet)^2 * 0.5 feet

Mulch = π * 400 square feet * 0.5 feet

Mulch = 200π cubic feet

To find the approximate value in decimal form, we can use the approximation π ≈ 3.14:

Mulch ≈ 200 * 3.14

Mulch ≈ 628 cubic feet

Rounding to the nearest tenth, we get:

Mulch ≈ 628.3 cubic feet

Therefore, the recommended amount of mulch for the flower bed with a radius of 20 feet and a desired depth of 0.5 feet is approximately 628.3 cubic feet.

The area of regular pentagon is 758.7 square in.(rounded to the nearest tenth.)

A pentagon is a specific type of polygon with 5 sides and 5 angles. The word “pentagon” is constructed of two words, namely Penta and Gonia, which defines five angles. So in a simplified way it can be said that pentagon is a polygon having 5 sides.

Two-variable equations are algebraic equations that involve two variables, typically x and y, and describe a relationship between them.

Let's call the tens digit "T" and the ones digit "O". Based on the problem, we know that:

T = 2 + O

Then substitute this equation in 10T + O = 10O + T + 27 i.e.

10T + O = 10O + T + 27

10T - T = 10O - O + 27

9T = 9O + 27

9(2 + O) = 8O + 27

9(2 + O) = 8O + 27

18 + 9O = 8O +  27

9O - 8O =  27 - 18

O = 9

Tina and Carl will use 6 and 12 ounces of clay, respectively. Tina uses 3/10 of the 20-ounce bucket and Carl uses 3/5 of the 20-ounce bucket.

To determine how much clay Tina and Carl will use, we need to first find the total amount of clay they will use together.

If 3/10 of the clay is used by Tina and 3/5 of the clay is used by Carl, we can find the total amount of clay used by adding these fractions:

3/10 + 3/5 = (3/10 * 1/2) + (3/5 * 1/2) (we multiply by 1/2 to find the common denominator of 10)

= 3/20 + 6/20

= 9/20

Therefore, Tina and Carl will use a total of 9/20 of the 20-ounce bucket of clay.

To find how much each of them will use, we can multiply the total amount of clay by each person's fraction:

Tina: (3/10) x 20 ounces = 6 ounces

Carl: (3/5) x 20 ounces = 12 ounces

Therefore, Tina will use 6 ounces of clay, while Carl will use 12 ounces of clay.

For Annually compounded interest:

A = P (1 + i)ⁿ

A = $9,200 (1 + 0.06)¹⁵

A = $9,200 (1.06)¹⁵

A = $22,048.34

For Semi-Annually compounded interest:

A = P (1 + i)ⁿ

A = $9,200 (1 + 0.03)³⁰

A = $9,200 (1.03)³⁰

A = $21,214.29

For Quarterly compounded interest:

A = P (1 + i)ⁿ

A = $9,200 (1 + 0.015)⁶⁰

A = $9,200 (1.015)⁶⁰

A = $20,947.34

For Monthly compounded interest:

A = P (1 + i)ⁿ

A = $9,200 (1 + 0.005)¹⁸⁰

A = $9,200 (1.005)¹⁸⁰

A = $20,812.09

For Weekly compounded interest:

1. Fill in the chart for the following investment.

A one-time investment is made in the amount of $9,200 for 15 years at an APR of 6%.

Compound Interest: A = P (1 + i)", where A is the final amount, P is the principal invested, i is the interest rate per compounding period, and n is the number of compounding periods.

Answer:

We can use the continuous compound interest formula:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the interest rate (as a decimal), and t is the time (in years). We can rearrange this formula to solve for t:

t = ln(A/P) / r

where ln is the natural logarithm function.

Using the given values, we have:

P = 920

A = 2310

r = 0.047

So,

t = ln(2310/920) / 0.047

t ≈ 18.8 years

Rounding to the nearest year, it would take about 19 years for the value of the account to reach $2310.

Next we have to multiply be the cost per square foot.

144 * 35

= $5040

Solve for the area.

A = 14 * 14

A = 196 ft^2

Multiply by the cost per square foot.

Assuming that we have two data sets, a and b, with means of 20 and 30, respectively, and the same standard deviation of 5, we can conclude that neither data set is more spread out than the other.

Suppose you have two data sets A and B, with means of 20 and 30, respectively, and the same standard deviation of 5. To determine which data set is more spread out, we need to compare the variance of the two data sets. Since the variance is the square of the standard deviation, we can compare the variances of the two data sets. Using the formula, Var = s², we can calculate the variances of data set A and B.

[tex]Var(A) = (5)^2 = 25\\Var(B) = (5)^2 = 25[/tex]
