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

Help pls with answer!!!Rewrite the function in the given form.
Elis [28]

Answer:

g(x) = \frac{-2}{x-1}+5\\\\

The graph is shown below.

=========================================================

Explanation:

Notice that if we multiplied the denominator (x-1) by 5, then we get 5(x-1) = 5x-5.

This is close to 5x-7, except we're off by 2 units.

In other words,

5x-7 = (5x-5)-2

since -7 = -5-2

Based on that, we can then say,

g(x) = \frac{5x-7}{x-1}\\\\g(x) = \frac{5x-5-2}{x-1}\\\\g(x) = \frac{(5x-5)-2}{x-1}\\\\g(x) = \frac{5(x-1)-2}{x-1}\\\\g(x) = \frac{5(x-1)}{x-1}+\frac{-2}{x-1}\\\\g(x) = 5+\frac{-2}{x-1}\\\\g(x) = \frac{-2}{x-1}+5

This answer can be reached through alternative methods of polynomial long division or synthetic division (two related yet slightly different methods).

-------------------------

Compare the equation g(x) = \frac{-2}{x-1}+5\\\\ to the form g(x) = \frac{a}{x-h}+k\\\\

We can see that

  • a = -2
  • h = 1
  • k = 5

The vertical asymptote is x = 1, which is directly from the h = 1 value. If we tried plugging x = 1 into g(x), then we'll get a division by zero error. So this is why the vertical asymptote is located here.

The horizontal asymptote is y = 5, which is directly tied to the k = 5 value. As x gets infinitely large, then y = g(x) slowly approaches y = 5. We never actually arrive to this exact y value. Try plugging in g(x) = 5 and solving for x. You'll find that no solution for x exists.

The point (h,k) is the intersection of the horizontal and vertical asymptote. It's effectively the "center" of the hyperbola, so to speak.

The graph is shown below. Some points of interest on the hyperbola are

  • (-1,6)
  • (0,7) .... y intercept
  • (1.4, 0) .... x intercept
  • (2, 3)
  • (3, 4)

Another thing to notice is that this function is always increasing. This means as we move from left to right, the function curve goes uphill.

Tristan and his friends are visiting chocolate shops in Salem. They take a cab from one
NemiM [27]

Answer:

8 inches

Step-by-step explanation:

Use a proportion.

2 inches is to 0.9 miles as x inches is to 3.6 miles

2/0.9 = x/3.6

0.9x = 2 * 3.6

x = 2 * 4

x = 8

Answer: 8 inches

What is the value of this expression when a=20 5a
Darina [25.2K]

Answer:

100

Step-by-step explanation:


Given :     a=20


To Find :  the value of  expression 5a.

Solution :

We are given the value of 'a' i.e. a=20

Now to find the value of given expression  5a


⇒5a


put a = 20 in the equation


⇒5*20


⇒100


⇒5a = 100


Thus , The value of expression 5a when a = 20 is 100
