Compare and contrast the absolute value of a real number to that of a complex number
Answer:
The absolute value of a real number is the distance from 0 on the number line. The absolute value of a complex number is the distance from the origin in the complex plane. Both are distances, and therefore both are positive values. You need to use the distance formula or the Pythagorean theorem to calculate the absolute value of a complex number.
Step-by-step explanation:
Use the distance formula or the Pythagorean theorem to calculate the absolute value of a complex number.
What is a complex number?Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfies the equation i² = 1.

which formula can be used to describe the sequence? 1.2, 3, 7.5, 18, 7.5, ...
Answer:
Option A) [tex]1.2(2.5)^{x-1}[/tex]
Step-by-step explanation:
We are given a series:
[tex]1.2, 3, 7.5, 18.75, ...[/tex]
We know that the given series is a geometric series as
[tex]\displaystyle\frac{3}{1.2} = \frac{7.5}{3} = \frac{18.75}{7.5} = 2.5[/tex]

Which value of r indicates a stronger correlation: r equals=0.828 or r equals= −0.879? explain your reasoning?
A value of r = 0.828 indicates a stronger positive correlation, while r = -0.879 indicates a stronger negative correlation.
Explanation:A stronger correlation is indicated by a value closer to 1 or -1. In this case, r = 0.828 indicates a stronger positive correlation, whereas r = -0.879 indicates a stronger negative correlation. The closer the absolute value of r is to 1, the stronger the correlation. A value of r = 0.828 suggests a strong positive relationship between two variables, while a value of r = -0.879 suggests a strong negative relationship.

One half of a number y is more than 22
Answer:
Inequality: [tex]\frac{y}{2}>22[/tex]
Solution: [tex]y>44[/tex]
Step-by-step explanation:
We are supposed to write and solve an inequality for the given verbal description.
One half of a number y would be y divided by 2: [tex]\frac{y}{2}[/tex].
Since one half of a number y is more than 22, so we can set an inequality as:
[tex]\frac{y}{2}>22[/tex]
Multiply both sides by 2:
[tex]\frac{y}{2}*2>22*2[/tex]
[tex]y>44[/tex]
Therefore, the solution to our given inequality is any value of y greater than 44.

An investor bought 400 shares of stock, some at $7.00 per share and some at $1.00 per share. If the total cost was $1450.00, how many shares of each stock did the investor buy?
The investor bought 175 shares at $7.00 per share and 225 shares at $1.00 per share.
Explanation:To solve this problem, you can set up a system of equations. Let x be the number of shares bought at $7.00 per share and y be the number of shares bought at $1.00 per share.
From the information given, we know that:
x + y = 400 (equation 1)7x + y = 1450 (equation 2)To solve the system of equations, you can use the substitution method or the elimination method.
Using the elimination method, multiply equation 1 by 7 to make the coefficients of x in both equations equal:
7(x + y) = 7(400)7x + 7y = 2800 (equation 3)Now, subtract equation 2 from equation 3 to eliminate x:
(7x + 7y) - (7x + y) = 2800 - 14506y = 1350y = 225Substitute the value of y into equation 1 to find x:
x + 225 = 400x = 175Therefore, the investor bought 175 shares at $7.00 per share and 225 shares at $1.00 per share.
what inequality represents the verbal expression? 8 less than a number n is less than 11
The inequality representing the verbal expression '8 less than a number n is less than 11' is written as 'n < 19'. This is found by adding 8 to both sides of the inequality 'n - 8 < 11'.
Explanation:The inequality that represents the verbal expression '8 less than a number n is less than 11' can be translated into a mathematical inequality as follows. First, '8 less than a number n' means you take 8 away from n, which is written as n - 8. Then, this quantity being 'less than 11' is represented by the inequality n - 8 < 11. To find the range of values for n, we solve this inequality.
Step 1: Add 8 to both sides of the inequality to isolate n -
n - 8 + 8 < 11 + 8
Step 2: Simplify -
n < 19
Therefore, the inequality symbol that represents the verbal expression is n < 19.
The inequality that represents the verbal expression '8 less than a number n is less than 11' is 8 < n < 11. The symbol '<' represents 'less than' and since the number n is between 8 and 11, we use the inequality symbol '<' twice.
The inequality that represents the verbal expression '8 less than a number n is less than 11' is 11 > n - 8 > 8.
Explanation:The inequality that represents the verbal expression '8 less than a number n is less than 11' is 11 > n - 8 > 8. This inequality states that the number n, decreased by 8, is greater than 8 and less than 11.

Jacqueline leaves city a at 2:00 p.m. and drives at a constant speed, traveling west on i-90. she passes city b, 40 mi from city a, at 2:50 p.m. (a) find a linear function d that models the distance (in mi) she has traveled after t min.
Jacqueline's speed is 0.8 miles per minute. The linear function representing the distance she has traveled in t minutes is d(t) = 0.8t. This equation means Jacqueline would have covered 0.8t miles after any given time t.
Explanation:The subject of this question is a linear function in mathematics, more specifically, it is about the concept of speed and distance. The question describes the journey of a person named Jacqueline who is traveling at a constant speed.
Given that city B is 40 miles from city A and it took Jacqueline 50 minutes to cover that distance, we can easily calculate her speed. Speed = Distance / Time. Therefore, her speed is 40 miles / 50 minutes = 0.8 miles per minute.
The linear function d, which models the distance she has traveled after t minutes would, therefore, be d(t) = 0.8t. The coefficient 0.8 indicates the speed, and the variable t is the time spent traveling. So, after any given number of minutes t, Jacqueline would have covered 0.8t miles on her journey.

Find the slope of the graph of the function y=5x/x-2 at (3,15). Then find an equation for the line tangent to the graph at that point.
The slope of the graph at the point (3,15) is -10. The equation of the tangent line at that point is y = -10x + 45.
Explanation:To find the slope of the graph, we need to differentiate the equation y=5x/(x-2). Using the quotient rule, the derivative of this equation is (5(x-2) - 5x)/(x-2)². Simplifying this further, we get -10/(x-2)². Now, substitute the x-coordinate of the point (3,15) into the derivative to find the slope at that point. Substituting x=3, we get a slope of -10/1 = -10.
To find the equation of the tangent line at the point (3,15), we use the point-slope form of a line, y - y1 = m(x - x1). Substituting the slope (-10) and the coordinates of the point (3,15) into this equation, we get y - 15 = -10(x - 3). Simplifying further, we get y - 15 = -10x + 30. Rearranging the equation, we get y = -10x + 45. Therefore, the equation of the tangent line to the graph at the point (3,15) is y = -10x + 45.
