Express the following vector in the form v=v1i+v2j+v3k. 3u - v if u=(4,7,-3) and v=(2,-7,5).3u - v = ____ i + ____ j + _____ k.(

Alecsey [184]

Answer:

<h2><em>5i+14j-7k</em></h2>

Step-by-step explanation:

Given the vectors u = (4,7,-3) and v=(2,-7,5), both vectors are 3-dimensional in nature and can also be rewritten as;

u = 4i+7j-3k and v = 2i-7j+5k

To get 3u-v, we will substitute the given vectors into the expression;

3u-v = 3(4i+7j-3k) - (2i-7j+5k)

open the parenthesis

3u-v = 12i+21j-9k - 2i + 7j - 5k

collect like terms

3u-v = (12i - 2i) + (21j + 7j) (-9k-5k)

3u - v = 10i+28j-14k

To simplify the answer, we will divide through by 2

3u - v = 10i/2+28j/2-14k/2

<em>3u - v = 5i+14j-7k</em>

<em>Hence the simplified form of the expression is 5i+14j-7k</em>

The miniature pinscher weighs 0.12 times the weight of a Doberman pinscher that weighs 32.65 kilograms. How much does the miniat

anastassius [24]

Answer:

3.918kg

Step-by-step explanation:

Given parameters:

Doberman Pinscher weight = 32.65kg

Unknown:

Miniature Pinscher weight = ?

Solution:

From the first sentence;

Miniature Pinscher's weight is 0.12 times Doberman Pinscher

Miniature Pinscher's weight = 0.12 x 32.65kg

Miniature Pinscher's weight = 3.918kg

What is the domain of the function?<br> x + 3<br> f(x) =<br> VX + 3

ahrayia [7]

Your question is a little ambiguous, but I am assuming that you meant to say the function $f(x) = x+3$

Thus, I am solving your question based on assuming the function such as

$f(x)=x+3$

But, it would still clear your concept, no matter what the function is.

Answer:

we conclude that

$\mathrm{Domain\:of\:}\:x+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

The graph is also attached.

Step-by-step explanation:

Given the function

$f(x)=x+3$

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

As the function has no undefined points nor domain constraints.

Thus, the domain is

$-\infty \:$

Therefore, we conclude that

$\mathrm{Domain\:of\:}\:x+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

The graph is also attached.

A cake with a regular hexagonal top is sliced along each of its 9 diagonals what percent of the resulting 24 pieces are triangle

jeyben [28]

<span>i guess it means that its a cake with a top shaped like a hexagon. if you were to use paper and cut out a hexagon then fold it, you would find out that it has 9 diagonals(meaning that you are able to fold it equally into 9 pieces). when it is unfolded, you will see 24 pieces and you will have to figure out which of the 24 pieces are triangles and which are not. after that, you calculate the percentage of triangles.

after you are finished with the paper, you apply the information to the cake.
i'm not sure if this is right, but you can try it out.</span>
