Answer:
d) 4 ± 5i
Step-by-step explanation:
Here we have to use the quadratic formula.
x = 
In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41
Now plug in the given values in the above formula, we get
x = 
Simplifying the above, we get
x = 
x = 
[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]
x = (8 ± 10i )/2
Now dividing by 2, we get
x = 4 ± 5i
The answer is d) 4 ± 5i
Hope you will understand the concept.
Thank you.
7-4=3
10-7=3
13-10=3
we can see that this is an arithmetic sequence with a difference of 3
the nth term=the first term +(n-1) times the difference
so a(n)=4+3(n-1)
Answer:
{(5, –4), (–4, 5), (–5, 4), (4, –5)}
Answer:
Y= -12x + 150
Step-by-step explanation:
1. You do the change in y over the change in x to get the slope.
y1 - y2 / x1 - x2 and you get the slope of -12
2. Making a point-slope form equation
y-y1=m(x-x1)
y-138= -12(x-1)
3. Turning point-slope form equation to slope-intercept
y-138= -12(x-1)
distributive property
y-138=-12x+12
add 138 on both sides
<h2><u>
y= -12x+150</u></h2>
