Answer:
y = -x - 3
Step-by-step explanation:
-44+18=-26degrees
negative 26 degrees is your answer
please mark brainliest and have a nice day
X² + 1 = 0
=> (x+1)² - 2x = 0
=> x+1 = √(2x)
or x - √(2x) + 1 = 0
Now take y=√x
So, the equation changes to
y² - y√2 + 1 = 0
By quadratic formula, we get:-
y = [√2 ± √(2–4)]/2
or √x = (√2 ± i√2)/2 or (1 ± i)/√2 [by cancelling the √2 in numerator and denominator and ‘i' is a imaginary number with value √(-1)]
or x = [(1 ± i)²]/2
So roots are [(1+i)²]/2 and [(1 - i)²]/2
Thus we got two roots but in complex plane. If you put this values in the formula for formation of quadratic equation, that is x²+(a+b)x - ab where a and b are roots of the equation, you will get the equation
x² + 1 = 0 back again
So it’s x=1 or x=-1
<span>A. cos(x) = cos(-x) [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph. [false]
C. cos(x) = -cos(x) [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin. [false]</span>
The given process is an example of a cluster system.
<h3>What is the cluster system?</h3>
The clustered systems are a combination of hardware clusters and software clusters.
The hardware clusters help in sharing of high-performance disks between the systems.
The software clusters makes all the systems work together.
Each node in the clustered systems contains the cluster software.
A cluster refers to a group of inter-connected computers where it works together to support applications and middleware (e.g. databases).
In a cluster, each & every computer is known to be a “node”.
