What is a complex number?Complex numbers are helpful in finding the square root of negative numbers.
A complex number is the sum of a real number and an imaginary number.
The idea of a complex number has come by solving a quadratic equation that has root as negative under root.
If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).
Given points, x,y, and z in a complex plan where an x-axis is a real number and the y-axis is an imaginary (i.e. i ) number.
So,
Point x is 3 units to the negative side and 2 units up so its coordinate will be (-3, 2i) so -3 + 2i.
Point w is 4 units to the positive side and 0 units up so its coordinate will be (4,0i) so 4 + 0i.
Point z is 4 units downside so its coordinate will be (0,-4i) so 0 + -4i.

A store sells a package of 25 trading hearts for $5.25 use pencil and paper explain how you can tell that the unit price per card is less than $1 what is the unit price per card.
Answer:
Unitary cost per card= $0.21
Step-by-step explanation:
Giving the following information:
Number of cards per packecge= 25
Total cost per package= $5.25
To calculate the unitary cost of each card, we need to use the following formula:
Unitary cost per card= total cost / number of cards per package
Unitary cost per card= 5.25 / 25
Unitary cost per card= $0.21
What is the solution to this equation?
Answer:
x = - [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
4x - 6 = 10x - 3 ( subtract 10x from both sides )
- 6x - 6 = - 3 ( add 6 to both sides )
- 6x = 3 ( divide both sides by - 6 )
x = [tex]\frac{3}{-6}[/tex] = - [tex]\frac{1}{2}[/tex]

D. 6x3 = 18
What is the value of value of 5/6 ÷ 3/4?
Answer:
answer is 10/9
:-)))☺️☺️
I hope it helps you
Answer: 1 and 1/9
Step-by-step explanation: Here, we have 5/6 ÷ 3/4.
Dividing by a fraction is the same as multiplying by its reciprocal.
In other words, we can change the division
sign to multiplication and flip the second fraction.
So here, 5/6 ÷ 3/4 can be rewritten as 5/6 × 4/3.
Now we're simply multiplying fractions so we multiply across the
numerators and multiply across the denominators.
So we have 5 × 4 which is 20 and 6 × 3 which is 18.
Notice that 20/18 is not in lowest terms so we divide the
numerator and the denominator of 20/18 by 2 to get 10/9.
If you would like, you can change this to the mixed number 1 and 1/9
by simply dividing 9 into 10 and putting the remainder over the denominator.

Step-by-step explanation:
Composite Figures
The image shows a figure that can be seen as a composition of three regular shapes: two identical rectangles and a quarter of a circle.
The area of a rectangle of dimensions W and L is:
Ar = WL
And the area of a circle of radius r is:
[tex]Ac =\pi r^2[/tex]
A quarter of a circle has an area of:
[tex]\displaystyle A_q =\frac{\pi r^2}{4}[/tex]
The rectangles have dimensions of 5 cm by 3 cm, thus the area is:
Ar = 5 cm * 3 cm = 15 square cm
The quarter of a circle has a radius of r=3 cm, its area is:
[tex]\displaystyle A_q =\frac{\pi 3^2}{4}[/tex]
Calculating:
[tex]\displaystyle A_q =7.07\text{ square cm}[/tex]
The total area is twice the area of each rectangle plus the area of the quarter of a circle:
A = 2*15 + 7.07
A = 37.07 square cm
To the nearest tenth:
A = 37.1 square cm
a half of 48 divided by6multiplied by4 plus 3 minus 2
Answer:
17
Step-by-step explanation:
follow the order of operations (PEMDAS): half of 48 is 24
24 / 6 = 4
4 x 4 = 16
16 + 3 = 19
19 - 2 = 17
Answer:
17
Step-by-step explanation:
half of 48 is 24
24 divided by 6 is 4
4× 4= 16
16+3= 19
19-2=17
If john had 2 apples and gave sandy 1 how many do they together
super easy
Answer:
2
Step-by-step explanation:
no. of apples with John= 2
no. of apple Sandy got= 1
so, no. of apple remaining with John= 2-1= 1
therefore,
altogether = 1+ 1 = 2.
hence, they have 2 apples altogether
Answer:
2
John have 2 apples and he gave 1 apple to sandy , John have 1 apple left and sandy also have 1 apple so 1+1 =2

Jerry has a garden that has a length of 30 feet and a width of 10 feet. Fertilizer is on sale for $2 per bottle. If each bottle covers 25 square feet, how much will it cost to fertilize the whole garden?
Answer: $50
Step-by-step explanation:
30 × 10 = 40 ft² [garden area]
40 ÷ 25 = 1.6
1.6 ≈ 2
For the area of the entire garden, you need to buy two bottles of fertilizer.
25 × 2 = 50 [fertilization cost for the whole garden]

w^8 × w¹
Using the law of indices
w^8 × w¹
= w^(8+1)
= w^9
-3w^8 × 9w

Rationalise the denominator.
9
√7-2
Answer:
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6[/tex]
Step-by-step explanation:
Rationalizing the Denominator
Rationalizing the denominator means to get rid of any radicals in the denominator.
We use the conjugate of the denominator to rationalize. The conjugate of a binomial is obtained by changing the sign that is between the two terms while keeping the same order of the terms. For example, the conjugate of
[tex]\sqrt{7}-2[/tex] is [tex]\sqrt{7}+2[/tex].
We need to use the algebraic identity:
[tex](a-b)(a+b)=a^2-b^2[/tex]
Let's rationalize
[tex]\displaystyle \frac{9}{\sqrt{7}-2}[/tex]
Multiply numerator and denominator by the conjugate of the denominator:
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9}{\sqrt{7}-2}\cdot\frac{\sqrt{7}+2}{\sqrt{7}+2}[/tex]
Operate in the numerator and apply the identity in the denominator
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9(\sqrt{7}+2)}{(\sqrt{7}-2)(\sqrt{7}+2)}[/tex]
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{(\sqrt{7})^2-2^2}[/tex]
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{7-4}=\frac{9\sqrt{7}+18}{3}[/tex]
Dividing:
[tex]\boxed{\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6}[/tex]
