Determine the relationship between the two vecors

Mathematics

1 answer:

Answer:

Step-by-step explanation:

Since there exists a scalar

(namely

λ=a⋅b

) such that

b=λa

, the directions of the two vertices are the same (they are collinear). This implies that

|a⋅b|=|a||b|

So,

|a|=|(a⋅b)b|=|a||b||b|

which implies that

|b|=1

It is known that the point P(-9,18) belongs to the graph of the function y=k/x. Find k.

riadik2000 [5.3K]

Answer:

$k = (-162)$ .

Step-by-step explanation:

A point of the form $(x_{0},\, y_{0})$ belongs to the graph of this function, $y = k / x$ , if and only if the equation of this function holds after substituting in $x = x_{0}$ and $y = y_{0}$ .

The question states that the point $(-9,\, 18)$ belongs to the graph of this function. Thus, the equation of this function, $y = k / x$ , should hold after substituting in $x = (-9)$ and $y = 18$ :

$y = k / x$ .

$18 = k / (-9)$ .

Solve this equation for the constant $k$ :

$\begin{aligned}k &= 18 \times (-9) \\ &= (-162)\end{aligned}$ .

Thus, $k = (-162)$ .

Please help!<br> Hard math.

Reil [10]

Answer:

the value of digit 3 in 156.32 =

3 x 0.1 = 0.3

The value of digit 3 in 13 =

3 x 1 = 3

3/0.3=10 times

The value of digit 3 in 13 is 10 ten times the value of digit 3 in 156.32

As long as the (digit in ones/single digit) of a number is equal to 3

The value of digit 3 of it is always 10 ten times the value of digit 3 in 156.32

The graph first represents the provided piecewise function option first is correct.

<h3>What is a piecewise function?</h3>

The graph of a piecewise function contains numerous curve components. It signifies that it has a plethora of definitions based on the value of the input. In other words, a piecewise function behaves differently depending on the input.

We have a piecewise function shown in the picture.

$\rm y=\left\{x\le-2:\sqrt{-x-2}\right\}$

$\rm y=\left\{-2 < x < 1:\dfrac{x}{x^{2}+x-2}\right\}$

$\rm y=\left\{x\ge1:\log_{2}\left(x+1\right)\right\}$

After plotting all the pieces of a function on the coordinate plane we will get a graph the same as shown in the first option.

Thus, the graph first represents the provided piecewise function option first is correct.
