8x+23/(x+3)(x+2) partial fraction decomposition

Mathematics
1 answer:
Natasha_Volkova [10]3 years ago
6 0

Answer:

1/(x+3)+7/(x+2)

Step-by-step explanation:

I'm assuming the full numerator is (8x+23)... and by making that assumption I'm assumed the fraction was (8x+23)/[(x+3)(x+2)].

(8x+23)/[(x+3)(x+2)]=A/(x+3)+B/(x+2)

8x+23=A(x+2)+B(x+3)                   I multiply both sides by (x+3)(x+2)

Set x to -2 that gives -16+23=B          so this means B=7

Set x to -3 instead that gives -24+23=A(-1)   so this means A=1

So (8x+23)/[(x+3)(x+2)]=1/(x+3)+7/(x+2)

Tcecarenko [31]

Answer:

B. (3,0)(0 ,-6)

Step-by-step explanation:

What is intercept.?

Intercept are those points where a given line cuts across a given axis.

So for the equation y = 2x - 6

To find the intercept we will bear in mind that we are looking for two points.

The point where the line cuts both the x axis and the y axis .

And to determine that, we will set both x and y to be equal to zero and then solve for both.

So let x = 0

Y = 2x -6

Y = 2(0) -6

Y = -6

One point = (0 ,-6)

Let y = 0

Y = 2x -6

0 = 2x -6

6 = 2x

X = 3

One point = (3,0)

The two points are

(3,0)(0 ,-6)

A plane traveling with a velocity measured in meters per second, is described by vector a = 5,6). Find the
ryzh [129]

Answer:

The speed of the plane is v=1.2\: m/s

Step-by-step explanation:

The vector (5,6) represents a point in the coordinate system time-position.

So, we have that at t = 5 s the position is x = 6.

Let's recall that the slope of this vector is the speed, then using the tangent definition:

v=\frac{x}{t}=\frac{6}{5}

v=1.2\: m/s

I hope it helps you!
