Find the area ___m^2

Answer: bellshaped

Step-by-step explanation:

Answer:

We can use the cosine double angle formula to find cos(2π/3):

cos(2θ) = cos^2(θ) - sin^2(θ)

Letting θ = π/3, we get:

cos(2π/3) = cos^2(π/3) - sin^2(π/3)

Using the values of cosine and sine of π/3 (which are known), we have:

cos(2π/3) = (1/2)^2 - (√3/2)^2

Simplifying, we get:

cos(2π/3) = 1/4 - 3/4

cos(2π/3) = -1/2

Therefore, cos(2π/3) is equal to -1/2.

Answer:

cos(2π/3) = cos(π/3 + π/3)

= cos²(π/3) - sin²(π/3)

= (1/2)² - (√3/2)²

= 1/4 - 3/4

= -2/4

= -1/2

Step-by-step explanation:

here are the steps:

Therefore, cos(2π/3) = -1/2

according to the given information we can say that the fraction of the area of the circle that is shaded is 1/4 or 0.25.

Every point in a horizontal surface that is a certain distance above another point forms a circle (centre). It is a circle made out of point that are separated from each other in a horizontal direction as a result. At all angles, it is rotating symmetric about the centre. In the closed, two-dimensional plane of a circle, each pair of points is evenly separated from the "centre." A line that pierces the circle creates a specular symmetrical line. At all angles, it rotates symmetrically about the centre.

given,

If the circle is divided into two equal parts and one of them is shaded, then the shaded area is half of the total area of the circle. So the fraction of the area of the circle that is shaded is 1/2 or 0.5.

If the circle is divided into four equal parts and one of them is shaded, then the shaded area is one-fourth of the total area of the circle. So the fraction of the area of the circle that is shaded is 1/4 or 0.25.

Therefore, the answer depends on how many equal parts the circle is divided into and the number of shaded parts.

Answer:

The lateral area of a cone is given by the formula:

L = πrs

Where r is the radius of the base, s is the slant height, and π is pi.

We are given that the lateral area L is 587π cm^2 and the radius r is 32 cm. Substituting these values into the formula, we get:

587π = π(32)s

Simplifying, we can cancel the π on both sides of the equation:

587 = 32s

Dividing both sides by 32, we get:

s = 18.34375

Rounding to the nearest tenth, we get:

s ≈ 18.3 cm

Therefore, the slant height is approximately 18.3 cm.

Step-by-step explanation:

The above prompts are related to the concepts of Degrees, Radians, Sines and Cosines. See the solutions below.

1)

(a) Cos 150 degrees

To convert 150 degrees to radians, we multiply by π/180:

150 degrees = (150π/180) radians = (5π/6) radians

We can use the unit circle and reference angle of π/6 to find the cosine of 5π/6:

cos(5π/6) = -cos(π/6) = -(√3/2) = -√3/2

Therefore, cos 150 degrees = -√3/2.

(b) Sin 240 degrees

To convert 240 degrees to radians, we multiply by π/180:

240 degrees = (240π/180) radians = (4π/3) radians

We can use the unit circle and reference angle of π/3 to find the sine of 4π/3:

sin(4π/3) = -sin(π/3) = -(√3/2) = -√3/2

Therefore, sin 240 degrees = -√3/2.

2)

To use the law of cosines, we need either a side and the two angles opposite that side, or two sides and the angle between them. In this case, we have two angles and the side opposite one of them, so we can use the law of sines to find the other side and then use the law of cosines to find the remaining side or angle.

Using the law of sines, we have:

sin A / AB = sin B / AC

where AC is the side opposite angle B. Substituting the given values, we get:

sin 52 / 26.7 = sin 70 / AC

Solving for AC, we get:

AC = sin 70 / sin 52 * 26.7 = 30.4

Now we can use the law of cosines to find the remaining side, x:

x^2 = AB^2 + AC^2 - 2ABACcos A

Substituting the given values, we get:

x^2 = 26.7^2 + 30.4^2 - 226.730.4*cos 52

Solving for x, we get:

x ≈ 22.1

Therefore, the missing side is approximately 22.1.

To find the area of the triangle, we can use the formula:

Area = (1/2) * a * b * sin C

where a and b are the lengths of the two sides, and C is the included angle. Substituting the given values, we get:

Area = (1/2) * 7 * 9 * sin 30

Using the fact that sin 30 = 1/2, we can simplify this to:

Area = (1/2) * 7 * 9 * (1/2) = 15.75

Therefore, the area of the triangle is 15.75 square units.

From the law of sines, we have:

sin A / a = sin B / b

Substituting the given values, we get:

sin 45° / (7√2) = sin B / 7

Solving for sin B, we get:

sin B = (7/7√2) * sin 45° = √2/2

Therefore, B = 45° or 135°. We can use the fact that the angles of a triangle sum to 180° to find C:

C = 180° - A - B = 90° or 0°

If C = 0°, then the triangle is degenerate and the sides a and b lie on top of each other. Therefore, we must have C = 90°.

Now we can use the Pythagorean theorem to find the remaining side:

c^2 = a^2 + b^2 - 2ab*cos C

Substituting the given values, we get:

c^2 = (7√2)^2 + 7^2 - 2(7√2)(7)*cos 90°

Solving for c, we get:

c = √(98 + 49) = √147 = 7√3

Therefore, the sides of the triangle are:

a = 7√2

b = 7

c = 7√3

Using the law of cosines to find x:

In triangle ABC with side lengths AB = 18, AC = 15, and angle A = 108 degrees, we want to find the length of side BC (denoted by x). Using the law of cosines:

x^2 = 18^2 + 15^2 - 2(18)(15)cos(108 degrees)

We can evaluate the cosine of 108 degrees using the identity cos(180 - 108) = -cos(108):

cos(108 degrees) = -cos(180 - 108 degrees) = -cos(72 degrees)

Substituting this into the equation above, we get:

x^2 = 18^2 + 15^2 - 2(18)(15)(-cos(72 degrees))

Simplifying:

x^2 = 729

Taking the square root of both sides:

x = ±27

Since x represents a length, we take the positive root:

x = 27

Therefore, the length of BC is 27 units.

Using the law of cosines to find theta:

In triangle ABC with side lengths AB = 20, BC = 12, and AC = 10, we want to find the measure of angle B (denoted by theta). Using the law of cosines:

cos(B) = (12^2 + 10^2 - 20^2) / (2(12)(10)) = -1/2

Since -1/2 is the cosine of an angle in the second quadrant, we have:

B = 180 degrees - arccos(-1/2)

Using a calculator, we find:

B ≈ 150.5 degrees

Therefore, the measure of angle B is approximately 150.5 degrees (or theta = 150.5 degrees).

The supplied value 4 is a solution to the equation m + 2(m + 1) = 14.

To solve the equation m + 2(m + 1) = 14 for the supplied value of m = 4, we substitute the value of m into the equation and simplify both sides of the equation.

First, we replace every occurrence of m in the equation with 4:

m + 2(m + 1) = 14

Substitute m with 4

4 + 2(4 + 1) = 14

The parentheses around (4 + 1) indicate that we need to add 4 and 1 together first, before multiplying by 2. This gives us:

4 + 2(5) = 14

We simplify further by performing the multiplication:

4 + 10 = 14

14 = 14

according to the question, the PLUS Loan will have a higher balance due at the time of repayment by $233.80 ($11,966.11 - $11,732.31).

Divide the principal times the interest rates, the length of time, and various other factors to arrive at simple interest. Simple return = principle + interest + hours is the marketing formula. The easiest way to compute interest is with this method. The most typical technique to figure out interest is to use a portion of the principal sum. He is only going to pay his share of the 100% interest, for example, if he loans $100 form a friend then agrees to pay it off with 5% interest. $100 (0.05) corresponds to $5. Interest must be paid as you borrow money and must be added to any loans you make. Interest is often determined as a yearly proportion of the loan total. The interest on the loan is this percentage.

given,

To compare the two loans, we need to calculate the total balance due for each loan at the time of repayment. We can start by calculating the balance due for the Unsubsidized Stafford Loan:

Principal: $10,720

Interest rate: 5.95% per year, compounded monthly

Time: 6 months grace period + 6 months repayment = 1 year

Number of periods: 12 months x 1/12 month per period = 12 periods

Using the formula for compound interest, the balance due on the Unsubsidized Stafford Loan after 1 year is:

B = P(1 + r/n)^(nt) + I [(1 + r/n)^(nt) - 1]/(r/n)

where B is the balance due, P is the principal, r is the annual interest rate, n is the number of times per year the interest is compounded, t is the time in years, and I is the monthly payment.

Plugging in the numbers, we get:

B = $10,720(1 + 0.0595/12)^(121) + $0 [(1 + 0.0595/12)^(121) - 1]/(0.0595/12)

B = $11,732.31

Now, let's calculate the balance due for the PLUS Loan:

Principal: $11,443.63

Interest rate: 6.55% per year, compounded monthly

Time: 6 months repayment

Number of periods: 6 periods

Using the same formula for compound interest, the balance due on the PLUS Loan after 6 months is:

B = $11,443.63(1 + 0.0655/12)^(120.5) + $0 [(1 + 0.0655/12)^(120.5) - 1]/(0.0655/12)

B = $11,966.11

Therefore, the PLUS Loan will have a higher balance due at the time of repayment by $233.80 ($11,966.11 - $11,732.31). Thus, the Unsubsidized Stafford Loan will have a lower balance due at the time of repayment compared to the PLUS Loan.

Answer:

a) 3/4

b) 21/4  

Step-by-step explanation:

To find the scale factor from A to B take any side of B and divide it by the corresponding side of A

The ratio will be the same for all sides

We have
scale factor = 3/4

We see that the sides 9 and 12 are also in this ratio: 9/12 = 3/4

a) So scale factor from A to B is 3/4

b) w of shape B corresponds to the side with length 7 in shape A

The ratio of w to 7 must be equal to the scale factor

So w/7 = 3/4

w = 7 x 3/4

w = 21/4

The equation that represents the relationship between the distances each girl has run is: Marcia = -3/4 * k + 6.5

Let x be the distance run by Tamara in kilometers.

Since Tamara has completed 3/4 of the race, then x = 3/4 * k.

Since Tamara is 2.5 kilometers ahead of Marcia, then x - 2.5 = 4 - Marcia.

Substituting the first equation into the second equation, we get:

3/4 * k - 2.5 = 4 - Marcia

Multiplying both sides by -1, we get:

Marcia - 4 = -3/4 * k + 2.5

Adding 4 to both sides, we get:

Marcia = -3/4 * k + 6.5
