The vectors are linearly independent if and only if?
Alexeev081 [22]

The vectors are linearly independent if and only if k ≠ -11

<h3>How to solve the vector</h3>

In mathematics, the definition of a vector is a quantity that is made up of both magnitude and also have direction. This type of quantity is not one that is considered based on its position. A very good example of such a quantity with magnitude and direction is acceleration.

Vectors are used to represent items such as position, velocity, physical quantities and others in mathematics and in physics.

In this question,

We have 2v - 3w

We have to multiply 2 by the values of v and multiply 3 with the values of w

this would produce

[2,6,8]-[6,6,12]

subtract w from v

= [-4, 0, -4]

We u as -1, 0 and 10+k

It is not possible to -1 = 10 + k

-11 = k

Hence we have to conclude that they are linearly independent if and only if k ≠ -11

Use a change of variables to find the indefinite integral xe^(x^2) dx
ValentinkaMS [17]
\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12\int2xe^{x^2}\,\mathrm dx

If we take y=x^2, then \mathrm dy=2x\,\mathrm dx, and we can write the above integral as


\displaystyle\frac12\int e^y\,\mathrm dy=\frac12e^y+C

and undoing the substitution, we end up with

\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12e^{x^2}+C

What is the equation of a line passing through the point
Anettt [7]

Answer:

y=5x-13

Step-by-step explanation:

<u><em>The correct question is</em></u>

What is the equation of a line passing through the point  (3, 2) and parallel to the line y=5x+4

step 1

Find the slope of the given line

we have

y=5x+4

This is the equation of the line in slope intercept form

The slope is m=5

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are equal

so

The slope  is  m=5

step 3

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=5

point\ (3,2)

substitute

y-2=5(x-3)

step 4

Convert to slope intercept form

y=mx+b

isolate the variable y

y-2=5x-15

y=5x-15+2

y=5x-13
