Answer:

-34 - 24i

Step-by-step explanation:

To calculate ( – 2 – 3i)^4, we can use the property that (a + bi)^n = a^n + (n*a^(n-1)b)i + (na^(n-2)*b^2)i^2 + ...

So, ( – 2 – 3i)^4 = (-2 - 3i) * (-2 - 3i) * (-2 - 3i) * (-2 - 3i)

= -2^4 - 2^3 * 3i - 2^2 * 3^2i^2 - 2 * 3^3i^3 - 3^4i^4

= -16 - 24i + 18i^2

Answer:

you could fit 7776 people on the gym floor for an event.

Step-by-step explanation:

The Locust Grove gymnasium has an area of 54 yd x 40 yd = 2160 square yards. To find the number of people that can fit on the gym floor, we need to convert the area of the gym floor to square feet and divide it by the number of square feet each person takes up.

We know that 1 yard = 3 feet, so we have to convert the area of the gymnasium in square yards to square feet by multiplying it by (3*3) = 9.

So the area of the gymnasium in square feet is 2160*9 = 19440 square feet.

To find the number of people that can fit on the gym floor, we divide the area of the gym floor by the number of square feet each person takes up.

19440 square feet / 2.5 square feet/person = 7776 people

We are aware that P = 2(a + b) units is the perimeter of a parallelogram.Consequently, the parallelogram's sides are 50 cm, 25 cm, 50 cm, and 25 cm.

We are aware that P = 2(a + b) units is the perimeter of a parallelogram.Adding up all four sides will reveal a parallelogram's perimeter.An area of a circle of radius r is known as r2 in geometry.

The circumference-to-diameter ratio, which is always the same and is roughly equivalent to 3.14159 in this context, is denoted by the Greek letter.

Let side a and the side next to it in the parallelogram be a and b, respectively.

The parallelogram's perimeter is equal to 2(a+b)=150, where a+b=75.

Since an is 25 cm taller than b, a=b+25.

By changing it in equation 1, b+25+b=75 2b=50 b=25 is obtained.

a+b=75\sa=75=25\sa=50

Consequently, the parallelogram's sides are 50 cm, 25 cm, 50 cm, and 25 cm.

3/2 does not have any factors because it is a fraction and factors are integers that can divide a number evenly. Only integers can have factors, fractions cannot.

Generally, A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another number to generate n. Another name for this concept is a factor of n. One may also state that n is a multiple of m in this particular scenario.

A number is considered to be a factor if the division of that number by that number results in no residue. If we get a product when we multiply two whole numbers, then the numbers we are multiplying are factors of the product since they are divisible by the product. In other words, we get a product when we multiply two whole numbers. Multiplication and division are the two techniques that may be used to discover factors.

Answer: The function f(x) = || is the absolute value function of x, which is defined as f(x) = |x|. The graph of this function is a "V" shape, with the vertex at the origin (0,0) and the lines x = 0 and y = 0 as the asymptotes. The graph of f(x) starts at the origin and increases as x increases or decreases, but never reaches x-axis.

The function g(r) = (-1)|r| is the absolute value function of r, multiplied by -1. The effect of multiplying the function by -1 is to reflect the graph of f(x) across the x-axis. So the graph of g(r) will be a "V" shape, with the vertex at the origin, and the lines x = 0 and y = 0 as the asymptotes. The graph of g(r) starts at the origin and decreases as r increases or decreases, but never reaches x-axis.

In summary, the effect of the change on the graph of f(x) = || is that it will be reflected across the x-axis.

The equation is solved and the values of a and b is simplified as

a) The possible values of ab = 4

b) The possible values of a + b = 4

c) The possible values of a and b = 2

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

(a)

To find all possible values of ab, we can use the identity:

a⁴ + b⁴ = (a² + b²)² - 2a²b²

Substituting the given values, we have:

16 = (a² + b²)² - 2a²b²

We also know that a + b=4, which means that b = 4 - a.

Substituting this into the equation above, we have:

16 = (a² + (4-a)²)² - 2a²(4-a)²

Simplifying, we get:

16 = (2a² - 8a + 16)² - 32a² + 64a³ - 32a⁴

Expanding, we get:

16 = 4a⁴ - 64a³ + 288a² - 512a + 272

Rearranging and factoring, we get:

4a⁴ - 64a³ + 288a² - 512a + 256 = 0

Dividing by 4, we get:

a⁴ - 16a³ + 72a² - 128a + 64 = 0

This is a quartic equation, which can be factored as:

(a-2)⁴ = 0

Therefore, the only possible value of a is 2, which means that the only possible value of b is 2 as well.

So, ab = 2 x 2 = 4

(b)

We know that a + b = 4, and since a = 2, we have b = 4 - a = 2

Therefore, the only possible value of a + b is 4

(c)

From part (b), we know that the only possible value of a + b is 4. From part (a), we know that the only possible values of a and b are both equal to 2.

Therefore, the only possible solution is a = 2 and b = 2

Answer:

To solve this problem, we will use the following steps:

Step 1: Let's assume that the larger number is x and the smaller number is y, we know that the difference between the two numbers is 9, so we can write the equation: x-y = 9

Step 2: We know that Four times the larger number plus one-half the smaller is 45, so we can write the equation: 4x + 0.5y = 45

Step 3: Now we have two equations with two unknowns, we can solve for one of the unknowns by isolating it in one of the equations.

x-y = 9

x = y+9

Step 4: Now we can substitute the value of x in the second equation

4(y+9) + 0.5y = 45

4y + 36 + 0.5y = 45

4.5y + 36 = 45

4.5y = 9

y=2

Step 5: We can substitute the value of y in one of the equation, to find the value of x

x-2 = 9

x = 11

Final Answer: The two numbers are 11 and 2.

Answer:

To solve this problem, we will use the following steps:

Step 1: Let's assume that the number of adult tickets sold is x and the number of senior/child tickets sold is y

Step 2: We know that the number of senior/child tickets sold was 27 less than twice the number of adult tickets sold, so we can write the equation: y = 2x - 27

Step 3: We also know that the total value of tickets sold was $2,647.50. Since adult tickets sold for $10 each and senior/child tickets sold for $7.50 each, we can write the equation: 10x + 7.5y = 2,647.50

Step 4: Now we have two equations with two unknowns, we can substitute one equation into another to find the value of x and y.

y = 2x - 27

10x + 7.5(2x - 27) = 2,647.50

10x + 15x - 405 = 2,647.50

25x = 3,052.50

x = 122

Step 5: We can substitute the value of x in one of the equation, to find the value of y

y = 2(122) - 27

y = 245

Final Answer: 122 adult tickets and 245 senior/child tickets were sold.

Note: We can check our solution by multiplying the number of adult tickets by $10 and the number of senior/child tickets by $7.5 to check if the total money is $2,647.50 which is true.

Answer:

30%.

Step-by-step explanation:

Ayo earns 50,000 monthly and he spends 35,000 altogether, so he saves the rest of his income. To find the percentage of his savings, we can divide his savings by his total income and multiply by 100.

His total income is 50,000

His total expenditure is 35,000

His savings = total income - total expenditure = 50,000-35,000 = 15,000

So the percentage of his savings = (savings / total income) x 100 = (15,000 / 50,000) x 100 = 0.3 x 100 = 30%

Therefore, Ayo's savings percentage is 30%.
