convert the following complex number into its polar representation 2+2i
Answer:
[tex]z=2\sqrt{2}(cos{\frac{\pi}{4}}+isin{\frac{\pi}{4}})[/tex]
Step-by-step explanation:
The given complex number is:
[tex]2+2i[/tex]
Now, the polar from of the complex number [tex]z=a+ib[/tex] is [tex]z=r(cos{\theta}+isin{\theta})[/tex].
Finding the absolute value of r:
[tex]r=|z|={\sqrt{2^2+2^2}[/tex]
[tex]r=\sqrt8[/tex]
[tex]r=2\sqrt{2}[/tex]
Now, find the value of argument,
Using formula, [tex]{\theta}=tan^{-1}(\frac{b}{a})[/tex]
[tex]{\theta}=tan^{-1}({\frac{2}{2})[/tex]
[tex]{\theta}=tan^{-1}(1)[/tex]
[tex]{\theta}={\frac{\pi}{4}}[/tex]
Thus, the polar form is:
[tex]z=2\sqrt{2}(cos{\frac{\pi}{4}}+isin{\frac{\pi}{4}})[/tex]
which is the required polar form.

Video games are on sale for 35% off if a particular game regularly sells for $99.50 what is the sales price
To find the sales price, multiply $99.50 by 35% to get the discount amount of $34.83, then subtract that from the original price, resulting in a sales price of $64.67.
Explanation:To calculate the sales price of a video game that has a discount of 35%, first determine the amount of the discount by multiplying the original price by the percentage of the discount. The original price of the video game is $99.50. Therefore, you calculate $99.50 × 0.35 to find the discount amount.
The discount amount is $34.825. Next, subtract the discount amount from the original price to find the sales price: $99.50 - $34.825 equals the sales price.
It's also important to round the discount to the nearest cent as currency, resulting in a discount of $34.83. Thus, the sale price of the video game will be $99.50 - $34.83, which equals $64.67.

Predict the vital capacity of a 20-year-old 5'5" female who weighs 120 pounds using the equation below: vc = (0.041) h - (0.018) a - 2.69
The predicted vital capacity of a 20-year-old, 5'5" female, using the provided equation, is approximately 3.97 liters.
Explanation:To predict the vital capacity of this 20-year-old 5'5" female who weighs 120 pounds using the given equation, we first need to convert the height from feet to centimeters since standard medical measurements are usually in metric units. The conversion is 1 foot = 30.48 cm. Therefore, 5'5" = 5*30.48 cm + 5*2.54 cm = 165.1 cm. Now we can substitute the height (h) and age (a) into the equation: vc = (0.041) h - (0.018) a - 2.69 = (0.041*165.1) - (0.018*20) - 2.69 ≈ 3.97 Liters. Therefore, the predicted vital capacity of this 20-year-old 5'5" female is approximately 3.97 liters.

Solution:
A is the correct option.
Explanation:
We have been given that [tex](2r - 3s)^{12}[/tex]
The [tex]r^{th}[/tex] term of a binomial expansion [tex](a+b)^n[/tex] is given by
[tex]t_r=^{n}C_{r-1}a^{n-r+1}b^{r-1}[/tex]

The volume of a cylinder is 1323pi cmcubed. The radius of the base of the cylinder is 7 cm. What is the height of the cylinder? The height of the cylinder is nothing cm. (Simplify your answer.)
The height of the cylinder with a given volume of 1323
cmcubed and a radius of 7 cm, divide the volume by the area of the base. The correct height is 27 cm.
The height of a cylinder given its volume and the radius of its base. To find the height, we'll use the formula for the volume of a cylinder, which is V = ()h, where V is the volume, is the radius and h is the height.
Step-by-step calculation:
The volume of the cylinder is given as 1323cmcubed.
The radius (r) of the base of the cylinder is given as 7 cm.
Plugging these values into the formula: 1323cm³= (7 cm)² imes h.
Simplify the equation: 1323cm³ = 49cm² imes h.
Divide both sides by 49cm² to find the height: h = 1323cm³ / 49cm².
The resulting height is therefore 27 cm, which is the solution to the problem.
The height of the cylinder is 27 cm.
Which of the following equations could be used to solve the given equation?
9x + 26 + 7x - 17 = 2x + (-3x) + 5x
16x + 9 = 0
16x + 9 = 4x
16x + 11 = 4x
Answer: The correct option is (B) [tex]16x+9=4x.[/tex]
Step-by-step explanation: We are given to select the correct equation that could be used to solve the following equation :
[tex]9x+26+7x-17=2x+(-3x)+5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To find the correct equation, we need to simplify the given equation (i).
From equation (i), we get
[tex]9x+26+7x-17=2x+(-3x)+5x\\\\\Rightarrow (9+7)x+(26-17)=2x-3x+5x\\\\\Rightarrow 16x+9=(2-3+5)x\\\\\Rightarrow 16x+9=4x.[/tex]
Thus, the required equation is [tex]16x+9=4x.[/tex]
Option (B) is CORRECT.

If there is a very strong correlation between two variables, then the coefficient of correlation must be
Final answer:
If there is a very strong correlation between two variables, then the coefficient of correlation must be close to 1 or -1.
Explanation:
The correlation coefficient measures the strength and direction of the relationship between two variables. If there is a very strong correlation between two variables, then the coefficient of correlation must be close to 1 or -1. A correlation coefficient of 1 indicates a perfect positive correlation, meaning the variables increase and decrease together.
A correlation coefficient of -1 indicates a perfect negative correlation, where one variable increases while the other decreases.
