Using DeMoivre’s theorem, the answer in regular form would be (5 + 5√3i)⁷ = -5000000 + 8660254.03i

The De Moivre's Theorem is used to simplify the computation of powers and roots of complex numbers and is used in together with polar form.

Convert the complex number to polar form. The polar form of a complex number is z = r(cos θ + isin θ),

r = |z|  magnitude of z

it becomes

r = √((5)² + (5√3)²) = 10

θ = arg(z) is the argument of z.

θ = atan2(b, a) = atan2(5√3, 5) = π/3

(5 + 5√3i) = 10 × (cos π/3 + i sin π/3)

De Moivre's theorem to raise the complex number to the 7th power

(5 + 5√3i)⁷

= 10⁷× (cos 7π/3 + i sin 7π/3)

= 10⁷ × (cos 2π/3 + i sin 2π/3)

Convert this back to rectangular form:

Real part = r cos θ = 10⁷× cos (2π/3) = -5000000

Imaginary part = r sin θ = 10⁷ × sin (2π/3) = 5000000√3 = 8660254.03i

∴  (5 + 5√3i)⁷ = -5000000 + 8660254.03i

Answer:10^7 (1/2 - √3/2 i)

Step-by-step explanation:

To use DeMoivre's theorem, we first need to write the number in polar form. Let's find the magnitude and argument of the number:

Magnitude:

|5 + 5√(3i)| = √(5^2 + (5√3)^2) = √(25 + 75) = √100 = 10

Argument:

arg(5 + 5√(3i)) = tan^(-1)(√3) = π/3

So the number can be written in polar form as:

5 + 5√(3i) = 10(cos(π/3) + i sin(π/3))

Now we can use DeMoivre's theorem:

(5 + 5√(3i))^7 = 10^7 (cos(7π/3) + i sin(7π/3))

To simplify, we need to find the cosine and sine of 7π/3:

cos(7π/3) = cos(π/3) = 1/2

sin(7π/3) = -sin(π/3) = -√3/2

Explanation:

So the final answer in rectangular form is:

10^7 (1/2 - √3/2 i)

The value of angle 1 given the value of angle 4 as 47° will be 133°

Parallel lines are two lines on a two-dimensional plane that, no matter how far they are extended, never collide. They always keep the same gap between them.

Parallel lines have the same slope, which means they have the same angle of inclination or steepness. In other words, they rise and fall at the same pace along their length.

The value will be:

The probability of rolling a single die and getting a 6 is 1/6. Since the rolls of the four dice are independent, the probability of getting a 6 on all four dice is (1/6) x (1/6) x (1/6) x (1/6), which simplifies to 1/1296.

To see why this is the case, consider that there are 6 possible outcomes for each roll of a single die (1, 2, 3, 4, 5, or 6). Therefore, the total number of possible outcomes for four rolls of a die is 6 x 6 x 6 x 6, or 1296. Out of these 1296 possible outcomes, only one of them is rolling four 6's. Thus, the probability of rolling four 6's is 1/1296.

Therefore, the probability of all four dice being 6's is very low, only 1/1296 or approximately 0.08%. This is because the chances of getting a specific number on a single die is relatively small, and the probability decreases with each additional die that is rolled.

The equation we need to find will relate the amount of remaining berries to the number of batches of jam the farmer can make is 16 = 2 1/2 + 2 1/4b (option b)

To start with, we know that the farmer picks 16 quarts of berries. Out of those, 2 1/2 quarts cannot be used, which means the farmer has 16 - 2 1/2 quarts of berries that can be used to make jam.

Now, the recipe requires 2 1/4 quarts of berries to make one batch of jam. Let's represent the number of batches of jam the farmer can make with the remaining berries as "b".

Therefore, the equation we need to find will relate the amount of remaining berries to the number of batches of jam the farmer can make is written as,

The measure of the larger acute angle of ΔABC is: α = 45° + φ/2. Option A.

Let's denote the angles of triangle ΔABC as follows:

∠A = x

∠B = y

∠C = 90° (right-angled triangle)

Let D be the midpoint of AB, so CD is the median. Let E be the point on AB such that CE is the height from point C.

Since CD is the median, we know that angle ∠ECD = φ.

In right-angled triangle ΔCEB, we have:

∠CEB = 90° - y

Now, let's examine triangle ΔCED. We know that the sum of the angles in a triangle is 180°. Therefore:

∠CED + ∠CEB + ∠ECD = 180°

Substitute the known values:

∠CED + (90° - β) + φ = 180°

Since ∠CED and ∠A are supplementary angles, we can also write:

∠CED = 180° - x

Now substitute this value into the previous equation:

(180° - x) + (90° - y) + φ = 180°

Simplify the equation:

270° - x - y + φ = 180°

Subtract 90° from both sides:

180° - x - y + φ = 90°

From this equation, we get:

x + y = 90°

Substitute this value back into the equation involving φ:

180° - (90°) + φ = 90°

Simplify:

90° + φ = 90°

Therefore, the measure of the larger acute angle of ΔABC is:

x = 45° + φ/2 (option a)

the above answer is in response to the full question below;

Triangle ΔABC, right angled at C, is given. Height and the median from point C form an angle φ. The measure of larger acute angle of Δ ABC is:

a. 45⁰ + φ/2

The invested amount dogwood tree is $15000 and on maple tree is $45000 as per linear equation.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."

Given, total invested amount is $60000.

Let, invested amount for dogwood trees is $x.

Therefore, invested amount for maple trees is ($60000 - x).

Now, the profit on a dogwood tree is 29% = 0.29.

The profit on a red maple tree is 17% = 0.17.

Again, the profit for the entire stock is 20%. = 0.20.

Therefore,

(x + x × 0.29) + [(60000 - x) + (60000 - x) × 0.17 = 60000 + 60000 × 0.20

⇒ 1.29x + 60000 - x + 10200 - 0.17x = 72000

⇒ 0.12x = 72000 - 60000 - 10200

⇒ 0.12 x = 1800

⇒ x = 15000

Therefore, invested amount  on dogwood tree is $15000.

Similarly, invested amount on maple tree is $(60000 - 15000) = $ 45000.

Step-by-step explanation:

The simplest way to calculate the surface area of a polyhedron, though, remains to simply sum the areas of the polygons that make up its faces. The surface area of a sphere has a very interesting formula. It depends solely on the radius of the sphere. The surface area of a sphere is equal to 4Π times the square of the radius of the sphere: 4Πr2.

In this question, measure of angle 4 is c. 60 degree. It has been calculated using properties of parallel lines.

It can be seen that in this question l and m are parallel lines and there is a transverse passing through it. We know through the properties of parallel lines that sum of ∠2 and ∠4 is 180° as they are consecutive interior angles and consecutive interior angles are supplementary meaning their sum is 180.

∠2 + ∠4 = 180° (consecutive interior angles)

120° + ∠4 = 180°

∠4 = 180 - 120

= 60°

Parallel lines are straight lines that never meet, no matter how far they are extended. Many pairs of angles are generated when two parallel lines are intersected by another line known as a transversal.

Some angles are congruent (equal), whereas others are supplementary (different).  Consecutive interior angles, also known as co-interior angles, develop on the inside of the transversal and are additional.

The basic relation of complex numbers is given as follows:

i² = -1.

The fraction for this problem is given as follows:
