What is the difference?
slega [8]

Answer:

<h3>The answer is option D.</h3>

Step-by-step explanation:

First we must first find the LCM

The LCM of x² + 3x + 2 and (x + 2)(x + 1 ) is

x² + 3x + 2

So we have

\frac{x}{ {x}^{2} + 3x + 2 }  -  \frac{1}{(x + 2)(x + 1)}  \\  \\  =  \frac{x - 1}{ {x}^{2} + 3x + 2 }

Hope this helps you

How can the Pythagorean Identity be used to find sin θ, cos θ, or tan θ and the quadrant location of the angle?
Archy [21]

First lets see the pythagorean identities

sin^2 \Theta + cos^2 \Theta =1

So if we have to solve for sin theta , first we move cos theta to left side and then take square root to both sides, that is

sin^2 \Theta = 1-cos^2 \Theta => sin \theta = \pm \sqrt{1-cos^2 \Theta}

Now we need to check the sign of sin theta

First we have to remember the sign of sin, cos , tan in the quadrants. In first quadrant , all are positive. In second quadrant, only sin and cosine are positive. In third quadrant , only tan and cot are positive and in the last quadrant , only cos and sec are positive.

So if theta is in second quadrant, then we have to positive sign but if theta is in third or fourth quadrant, then we have to use negative sign .

Which relationship shows an inverse variation?
PIT_PIT [208]
In inverese, when x increases, y deceases, when x decreases, y increses

we see that x increases for all choices

therefor the y values of the answer should be decreasing

first one is increasing, wrong
second is decreasing
third is also decreasing
fourth is increasing


look at second and third

remember
xy=k for inverse
so just solve for k for each and see if it is valid

second
1,60
(1)(60)=k
60=k

2,30
(2)(30)=60
60=60
true

therefor this is nswer
