What is n?

–13 + 4i
–13 - 4i
The value of n that makes the equation [tex](13 + 4i) + n = 0[/tex] true is (d) -13 - 4i.
The equation is given as:
[tex](13 + 4i) + n = 0[/tex]
Remove brackets
[tex]13 + 4i + n = 0[/tex]
Subtract 13 from both sides
[tex]13 - 13 + 4i + n = 0 - 13[/tex]
Evaluate like terms
[tex]4i + n = - 13[/tex]
Subtract 4i from both sides
[tex]4i -4i + n = - 13 -4i[/tex]
Evaluate like terms
[tex]n = - 13 -4i[/tex]
The equation cannot be further simplified.
Hence, the value of n is (d) -13 - 4i

A motorized float in a Thanksgiving Day parade is traveling north at a speed of 16.0 km/h. Part of a "Pilgrim" woman's role in the thematic vignette is to walk across the float to call the men to dinner. She walks at a speed of 3.22 km/h east as the float passes the judge's booth, which is on the west side of the street. What is the woman's velocity with respect to the judge?
Answer:
16.32 N11.38°E km/h
Step-by-step explanation:
16.0∠0° +3.22∠90° ⇒ (x, y) = (3.22, 16.0) ⇒ (r, θ) =
(3.22, 16.0) ⇒ (r, θ) = (√(3.22² +16²), arctan(3.22/16)*) = (16.32, 11.38°)
The woman's velocity is 16.32 km/h in a direction that is 11.38° east of north.

Answer:
k = -3x
Step-by-step explanation:
To find the slope, use rise over run
I started from (0, 0)
To get to the next whole number point, you must go up (rise) 3 and go back (run) 1
Since we are going back, the slope is negative.
The rise over run is -3/1 which simplifies to -3
To find y-intercept, we look at the point when x = 0. When x = 0, y = 0 so the y-intercept is 0 (which means you don't have to include it into the equation
y = -3x or k if that's what you use

Which describes how to graph g) XH +7 by transforming the parent function? Translate the parent function 5 units to the left and 7 units up OTranslate the parent function 5 units to the right and 7 units up. OTranslate the parent function 5 units down and 7 units to the right. OTranslate the parent function 5 units up and 7units
Answer:
Step-by-step explanation:
The translation rule:
The parent function is translated 5 units to the right and 7 units up.
What is transformation on the graphs?Let the functions f(x) and g(x) be two real functions.
And g (x) = f (x) + k, where k is real numbers.
The function can be sketched by shifting f (x), k units vertically.
The direction of shift can be found by the value of k:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
The function provided by the basic function f(x) and the constant
g(x) = f(x - k),
may be drawn by horizontally moving the f(x) k unit coordinates.
The shift's direction depends on the value of k. Specifically,
The base graph moves k units to the right if k > 0, and
The base graph moves k units to the left if k < 0.
To graph the function g(x) = ∛(x - 5) + 7, we need to transform the parent function f(x) = ∛x.
We can achieve this transformation by first translating the function 5 units to the right and then 7 units up.
This is because the "x - 5" inside the cube root shifts the function horizontally to the right by 5 units, and the "+7" outside the cube root shifts the function vertically up by 7 units.
Therefore, the correct answer is to translate the parent function 5 units to the right and 7 units up.

The highest yielding savings accounts are paying historically low
interest rates, so Maria is only able to get a 2% annual interest rate
for her savings account. Assuming interest rates do not change,
use the Rule of 72 to approximate how many years it will take for
her to DOUBLE her money in this account? *
1 year
5 years
10 years
36 years
Answer:
36 years
Step-by-step explanation:
Maria interest rates was to get 2% annual. Her interest rate do not change of 72. So you will have to divide 72 out of 2 which that will give you 36 . 36 years is your answer.
Maria's money would double in 36 years
The rule of 72 is an heuristic that is used to determine in how many years it would take an investment to double given the interest rate
Rule of 72 = 72 / interest rate
72 / 2% = 36 years
Assume Maria has $10,000 in her account, it would take 36 years for the money to double.

6. Audrey's monthly car payment is $350 and
she needs to save at least $35 each month for
gas. If Audrey is paid $17.50 an hour, write
and solve an inequality to represent the
number of hours she must work in a month to
pay for her car payment and gas.
The number of hours she must work in a month to pay for her car payment and gas is 22 hours
What is inequality?inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
For one month, Audrey has to pay $350 for her payment and $35 for gas, meaning that she will need to pay $385 per month.
$350 + $35 = $385
Audrey makes $17.50 an hour. Set up equality to find the number of hours she must work to pay for her car payment and gas.
17.50x > 385
(17.50x)/17.50 > 385/17.50
x > 22
Therefore, Audrey must work at least 22 hours to pay for her car payment and gas.

Jenny and her children went to the SeaWorld.She purchased adult ticket for herself and children tickets for her 2 boys. Tickets cost $39.99 for one adult and $19.99 for each child. Let x represent the number of adult ticket purchase and y represent the number of child tickets purchase. Write an expression to represent the total cost of the tickets Jenny purchased
Given:
She purchased adult ticket for herself and children tickets for her 2 boys.
Cost of one adult ticket = $39.99
Cost of one child ticket = $19.99
To find:
The expression to represent the total cost of the tickets Jenny purchased.
Solution:
Let x represent the number of adult ticket purchase
and y represent the number of child tickets purchase.
Cost of one adult ticket = $39.99
Cost of one child ticket = $19.99
Total cost = 39.99x + 19.99y
Therefore, the expression for total cost is 39.99x + 19.99y.
She purchased one adult ticket and 2 child tickets.
Substitute x=1 and y=2 in the above expression.
Total cost = 39.99(1) + 19.99(2)
= 39.99 + 39.98
= 79.97
Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.

When the number of bricks is multiplied by 2, the length is multiplied by
1.
2.
3.
6.
Answer:
The length will be multiplied by 2.
Step-by-step explanation:
By looking at the first and third ratio, we know that the no. of birck have been multiplied by 2 and the length has also been multiplied by 2 .
So when the number of bricks is multiplied by 2, the length is multiplied by 2
Answer:
2Step-by-step explanation:
Using the table we observe the points
(6, 3) and (12, 6)The number of bricks doubled
6*2 = 12, andThe length is doubled accordingly
3*2 = 6So the answer is 2
Prove that when 2 lines intersect each other ,then the vertically opposite angles formed are equal.
plz help fast
Answer:
Because both lines intersect at one given point, this means that wherever they intersect both lines will have the same length on each side because that one point serves as the half way point between the intersection. meaning that if two lines cross and it creates the vertical angle of 150⁰ then by definition the side that is across that intersection point will also be 150⁰
Answer:
Step-by-step explanation:
If two lines i.e. AB & CD intersect each other. They have two pair of opp. angles.
i.e.
∠AOC,∠DOB,∠AOB,∠COB.
To prove :- ∠AOC=∠DOB & ∠AOD=∠COB
Proof :-
∠AOC+∠AOD=180 °
[linear pair] ___(1)
∠AOD+∠BOD=180°
[linear pair] ___(2)
from eq. (1) & (2)
∠AOC+∠AOD=∠AOD+∠BOD
i.e. [∠AOC=∠BOD]
Similarly [∠AOD=∠COB]
Hence proved.
