The simplified expression for the complex expression is -56-52i

What is a complex expression?

A complex expression is an expression of the form a+ ib where a , b are constant and i is the imaginary number known as iota. In a + ib a is the real part and b is the imaginary part.

We are given two complex number as (8-8i) and (8+4i)

We have to simplify the given expression

As Complex number are added multiplied subtracted same as real number we can simplify the expression easily

2(8-8i)-9(8+4i)

We multiply the constants inside the bracket

16-16i-72-36i

Separating the terms and simplifying them we get

-56-52i

Hence the simplified expression is -56-52i

Answer:

Step-by-step explanation:

let x = number of 3 wheel stollers

let y = number of 4 wheel strollers

x + y = 28

y = 28 - x

3x + 4y = 100

3x + 4(28 - x) = 100

3x + 112 - 4x = 100

-x = -12

x = 12

Answer:

$4.30

Step-by-step explanation:

First, find the cost of both games by multiplying the price by 2:

7.85(2)

= 15.7

Then, to find his change, subtract this from 20:

20 - 15.7

= 4.3

So, Luke should get $4.30 back in change.

The derivative dz/dt can be found by applying the chain rule. Let's first substitute the given expressions for x and y into the equation for z:

z = (x + y)e^y

z = (3t + 1 - t^2)e^(1 - t^2)

Now, we can differentiate z with respect to t using the chain rule. The chain rule states that if u = f(g(t)), then du/dt = f'(g(t)) * g'(t).

Applying the chain rule to the given equation, we have:

dz/dt = d((3t + 1 - t^2)e^(1 - t^2))/dt

To differentiate this expression, we need to consider the derivative of each term. Let's break it down:

1. The derivative of 3t with respect to t is simply 3.

2. The derivative of 1 with respect to t is 0 since it is a constant.

3. The derivative of -t^2 with respect to t is -2t.

4. The derivative of e^(1 - t^2) with respect to t can be found using the chain rule again.

For the fourth term, let's define u = 1 - t^2. The derivative of u with respect to t is du/dt = -2t. Now, we have:

dz/dt = (3 + 0 - 2t)e^(1 - t^2) + (3t + 1 - t^2)d(e^(1 - t^2))/dt

Using the chain rule once more, we differentiate e^(1 - t^2) with respect to u:

d(e^(1 - t^2))/du = e^(1 - t^2) * d(1 - t^2)/dt

The derivative of 1 - t^2 with respect to t is -2t. Substituting this back into our expression, we get:

dz/dt = (3 + 0 - 2t)e^(1 - t^2) + (3t + 1 - t^2)(-2t)e^(1 - t^2)

Simplifying the expression, we have:

dz/dt = (3 - 2t)e^(1 - t^2) - 2t(3t + 1 - t^2)e^(1 - t^2)

Therefore, the derivative dz/dt is given by (3 - 2t)e^(1 - t^2) - 2t(3t + 1 - t^2)e^(1 - t^2), where e represents the exponential function.

Step-by-step explanation:

first convert to /12 and put the wholes in the fraction:

6 3/4 = 81/12

4 11/12 = 59/12

Then perform the subtraction

81/12 - 59/12 = 22/12

... and simplify

22/12 = 11/6

separate the wholes

11/6 = 6/6 + 5/6 = 1 5/6

Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expression is given below.

⇒ [(x² - 3x - 10) / (x + 3)] / [(2x² - 7x - 15) / (x² - 9)]

Simplify the expression, then we have

⇒ [(x² - 3x - 10) / (x + 3)] / [(2x² - 7x - 15) / (x² - 9)]

⇒ [(x² - 3x - 10) (x² - 3²)] / [(2x² - 7x - 15) (x + 3)]

⇒ [(x² - 5x + 2x - 10) (x - 3)(x + 3)] / [(2x² - 10x + 3x - 15) (x + 3)]

⇒ [(x - 5)(x + 2)(x - 3)] / [(2x + 3)(x -  5)]

⇒ [(x + 2)(x - 3)] / (2x + 3)

⇒ (x² - x - 6) / (2x + 3)

The expression in the simplified form will be (x² - x - 6) / (2x + 3). Then the correct option is C.

You can use the sine rule

a / sinA = b / sinB

Substitute the values in:

15 / sin112 = b / sin33

Multiply both sides by sin(33) to get b by itself

b = (15 / sin112) x sin33

Calculate this to get your answer of:

BC = 8.8 cm

2.

You can also use the sine rule here

sinA / a = sinB / b

Sub your values in:

sin84 / 32.4 = sin(y) / 21

Multiply both sides by 21 to isolate sin(y)

(sin84 / 32.4) x 21 = sin(y)

Calculate sin(y)

sin(y) = 0.6445975248

You now need to sin-1 this value to get u:
