The product of two numbers is 41. One of the numbers
is the complex number 5+4i. What is the other
number?
A. 5-4i
B. 5+4i
C. -5-4i
D. -5+4i
E. 41/5-4i
Answers
===================================================
Work Shown:
x = the other number
(5+4i)*x = 41
x = 41/(5+4i)
x = 41*(5-4i)/( (5+4i)*(5-4i) ) ..... see note below
x = 41*(5-4i)/( 41 )
x = (41/41)*(5-4i)
x = 5 - 4i
As a way to check, (5+4i)*(5-4i) = 5^2+4^2 = 25+16 = 41
The rule used is (a-bi)(a+bi) = a^2 + b^2
-----------
Note: I multiplied top and bottom by (5-4i) to get rid of the imaginary term in the denominator.

Answers
Answer: 4.2
Step-by-step explanation:
Here's the formula for how to find the hypotenuse: (a and b are the two legs for the triangle-- it doesn't matter which leg is a and which leg is b, but c MUST be the hypotenuse)
[tex]a^2+b^2=c^2[/tex]
[tex]1.9^2+3.8^2=c^2[/tex]
[tex]3.61+14.44=c^2[/tex]
[tex]18.05=c^2[/tex]
[tex]\sqrt{18.05} =c[/tex]
[tex]c=4.2[/tex]
Given from question
h= ? , b=1.9mm and p=3.8mm
We know h^2 = b^2 + p^2
So = (3.8)^2 + (1.9)^2
= 14.44+3.61
=18.05
We know h^2 = 18.05 so
:• h = 4.25mm so

A max subscription for Twitch, a streaming service, costs a flat fee of $25. You can then also buy small subscriptions for others for $5 per subscription. Johnny is trying to budget the amount of money he wants to spend.
Let y represent the total amount of money spent, and x represent the number of small subscriptions he purchases.
Answers
Answer:
y = 25 + 5x
Step-by-step explanation:
Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.
