Answer:
Step-by-step explanation:
If the roots are 1 + 5i and 1 - 5i, then you need the factors that result from those roots. They are (x - 1 + 5i) and (x - 1 - 5i). Now what you do with those is FOIL them out. Doing that gives you the following:
(what a mess, huh?)
The good thing is that several of those terms cancel each other out. +5ix cancels out the -5ix; -5i cancels out the 5i; and the 2 -x terms combine to -2x. That leaves you with:
Obviously you're in the section in math that deals with complex (imaginary) numbers so you should know that i-squared is equal to -1. Making that replacement:
a = 1, b = -2, c = 25
Answer:
The multiples of 4 are: 4,8,12,16,20,24,28,32,36,40,44,.
Step-by-step explanation:
so no
No, the answer is 3/8 because if 3/4 of the cars are Sudan's, and half of that three quarters are white, you need to divide three quarters into two to get the answer. I did this question by using the equivalent fraction 6/8 and dividing both numbers into two.
3/5 × 20/1 = 12 because 3×20 is 60 and 5×1 is 5 so 60/5 and that simplifies to 12
Answer:
$73,000
$43,000 + $5,000 x t
Step-by-step explanation:
Every year increase $5,000, after 6 years increase $5000 x 6 = $30,000
Her salary will be $43,000 + $30,000 = $73,000
After t years, her salary will be
$43,000 + $5,000 x t
