simplify(-2+8i)(-2+6i)
Answers
The product between the complex numbers gives:
(-2 + 8i)*(-2 + 6i) = -44 - 28i
How to simplify the expression?Here we have the product of two complex numbers.
It is (-2 + 8i)*(-2 + 6i)
Expanding that we will get:
(-2 + 8i)*(-2 + 6i) = (-2)*(-2) + (-2)*(6i) + (-2)*(8i) + (8i)*(6i)
Remember that i² = -1, then we will get:
(-2)*(-2) + (-2)*(6i) + (-2)*(8i) + (8i)*(6i) = 4 - 12i - 16i - 48
= -44 - 28i

The graph of this function will behave as (b) A graph of this function would slope downward, starting from a price of $100 dollars because the rate of change is less than 0 and the initial value is -10.
The demand function is given by d = 100 - 10p. This means that the quantity demanded (d) decreases as the price (p) increases.
The slope of the demand function is the rate of change of the quantity demanded with respect to the price. In this case, the slope is -10, which is negative. This indicates that as the price increases, the quantity demanded decreases.
The initial value of the demand function is 100, which represents the quantity demanded when the price is zero. This means that the demand function intersects the y-axis at (0, 100).
Therefore, the correct answer is (b) A graph of this function would slope downward, starting from a price of $100 dollars because the rate of change is less than 0 and the initial value is -10.

HELP ASAP! What is the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the triangle?
Answers
Answer:
Step-by-step explanation:
To answer this question, we need to know the dimensions of the rectangle and the triangle. Assuming that the triangle is right-angled and has one side coinciding with one side of the rectangle, we can use the formula for the area of a triangle: \ ( \frac {1} {2} \) × base × height1. The base and height of the triangle are the same as the length and width of the rectangle. The area of the rectangle is length × width. The probability that a point chosen randomly inside the rectangle is in the triangle is then the ratio of the area of the triangle to that of the rectangle, which is: \ ( \frac {\frac {1} {2} \times length \times width} {length \times width} \) = \ ( \frac {1} {2} \). So, the probability is 0.5 or 50% to the nearest hundredth2.
Answer: C .08
Step-by-step explanation:
Probability is the part out of the whole. you first need to find the part, which is the triangle
In other words find out how much of the triangle is taking up the rectangle, which is done through area
A(triangle)=1/2 b h where b=6 h=9
A(triangle)=1/2 (6)(9) = 27
A(rectangle)= Lw where L=24 h=15
A(rectangle)= (24)(15) = 360

WXYZ is a parallelogram. If ZX = 104 and ZU = 11c-3, find the value of c.
Answers
The value of c for the parallelogram WXYZ is 5
What is Parallelogram?Parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary and the opposite sides need to be parallel.
How to determine this
When WXYZ is a Parallelogram
ZX = 104
ZU = 11-2c
By using the law of parallelogram
ZU = UX
Therefore, ZX = ZU + UX
Where ZU = UX
So, 104 = 11c- 23 + (11c -3)
104 = 11c - 3 + 11c - 3
104 = 11c + 11c - 3 - 3
104 = 22c - 6
Collect like terms
104 + 6 = 22c
110 = 22c
Divides through by 22
110/22 = 22c/22
5 = c
Therefore, the value of c = 5

Answers
Answer:
The series ∑6n=1 3n is a sum of the first 6 terms of the sequence 3n, which starts with n = 1 and increases by 3 for each successive term. Therefore, the first 6 terms of the sequence are:
3(1), 3(2), 3(3), 3(4), 3(5), 3(6)
which simplify to:
3, 6, 9, 12, 15, 18
The sum of these terms is:
∑6n=1 3n = 3 + 6 + 9 + 12 + 15 + 18 = 63
Therefore, S6, the sum of the first 6 terms of the series, is 63.

What is Variance?Variance, as a statistical measure, evaluates the level of variability or dispersion contained in a dataset by inspecting how distant each value in a set is from the mean of that same set.
If there is a higher variance, it signals that data points are more widely distributed and further removed from the mean, whereas if there is a lower variance, one can assume that they are primarily clustered more closely around the mean.
To obtain the variance value, one must determine an average signal-to-noise ratio for each squared difference derived from every respective value taken away from the arithmetic mean. It is no exaggeration to say that variance is progressively employed across diverse subject areas including finance, engineering, and science.

What is a formula for the nth term of the given sequence?
12,6,3...
Answers
Answer:
The given sequence is decreasing by a factor of 2 each time, so each term is half of the previous term.
We can write the nth term of the sequence as:
a_n = a_1 * (1/2)^(n-1)
where a_1 is the first term of the sequence (12 in this case) and n is the position of the term we want to find.
For example, to find the 4th term of the sequence, we would have:
a_4 = 12 * (1/2)^(4-1)
= 12 * (1/2)^3
= 12 * 1/8
= 1.5
Therefore, the formula for the nth term of the sequence 12, 6, 3, ... is:
a_n = 12 * (1/2)^(n-1)

Answers
Using the expression 5x/12 = 20, the amount that A originally had was $48.
We have,
Let x be the amount of money that A originally had.
Then, A gave away 1/2 x 1/3 = 1/6 of the amount, which is equal to x/6.
The amount received by B is 1/2 of the remaining amount,
which is (x - x/6)/2 = 5x/12.
We know that 5x/12 = 20,

Find the surface area of the prism a.120cm. B180cm. C34cm. D 333cm
Answers
The surface area of the prism for the given dimensions is equal to option B. 180 square centimeters.
Surface area of the prism
= Area of two right triangles + Area of rectangle 1 + Area of rectangle 2 + Area of the rectangle3
In a Triangle ,
Base = 12cm
height = 5cm
Area of the triangle = ( 1/2 ) × base × height
= (1/2)× 12 × 5
= 30 cm²
Length of rectangle 1 = 12cm
Width of rectangle 1 = 4cm
Area of rectangle 1 = 12 × 4
= 48 cm²
Length of rectangle2= 13cm
Width of rectangle 2 = 4cm
Area of rectangle 2= 13 × 4
= 52 cm²
Length of rectangle 3 = 5cm
Width of rectangle 3 = 4cm
Area of rectangle 3 = 5 × 4
= 20 cm²
Surface area of the prism
= Area of two right triangles + Area of rectangle 1 + Area of rectangle 2 + Area of the rectangle3
Substitute the values of the area we have,
⇒ Surface area of the prism = 2(30 ) + 48 + 52 + 20
⇒ Surface area of the prism = 180 square centimeters

(ii) [tex]\lim_{x \to \frac{\pi^+}{2}}[/tex] h(x) = -1
(iii) h(0) = 1/7
The value of λ must be 7, for h(x) to be continuous at x = 0.
The given function is,
h(x) = 1/7, when x = 0

= x cos x/sin λx, when x < 0
Now,
(i) [tex]\lim_{x \to \frac{\pi^-}{2}}[/tex] h(x) = [tex]\lim_{x \to \frac{\pi^-}{2}}[/tex] (1 - 2 cos 2x) = 1 - 2 cos π = 1 + 2 = 3
(ii) [tex]\lim_{x \to \frac{\pi^+}{2}}[/tex] h(x) = [tex]\lim_{x \to \frac{\pi^+}{2}}[/tex] (1 + 2 cos 2x) = 1 + 2 cos π = 1 - 2 = -1
(iii) h(0) = 1/7
Since the function is continuous at x = 0, so
[tex]\lim_{x \to 0}[/tex] h(x) = h(0)
[tex]\lim_{x \to 0}[/tex] x cos x/sin λx = 1/7

1/λ = 1/7
λ = 7
Hence the value of λ must be 7.

In a class of 50 students, they had a chance to read novel,comics and textbook 21 read novel,24 read comics and 18 read textbook 3 read only novel 9 read only comics and 2 read only textbook 5 read all the 3. illustrate your information on a venn diagram. use your diagram to find the number of students who read a. comics and novel only b. textbook and novel only c. none of the 3
Answers
Answer:
Here is a Venn diagram that illustrates the information:
```
___________
| |
| N |
|_____ ____|
|\ || /|
| \ || / |
| \ || / |
| \ || / |
| C \||/ T |
|_____\v/____|
A
```
In the diagram, N represents the set of students who read the novel, C represents the set of students who read the comics, and T represents the set of students who read the textbook. The region labeled A represents the set of students who read all three.
Using the Venn diagram, we can find the number of students who read:
a. comics and novel only: This corresponds to the region of the diagram that is exclusively shaded with the circles for comics and novel, but not for textbook. This region has 9 students.
b. textbook and novel only: This corresponds to the region of the diagram that is exclusively shaded with the circles for textbook and novel, but not for comics. This region has 1 student.
c. none of the 3: This corresponds to the region of the diagram that is outside of all three circles. This region has 13 students.
Therefore, the number of students who read a. comics and novel only is 9, b. textbook and novel only is 1, and c. none of the 3 is 13. Answer: a. 9, b. 1, c. 13.
