By applying concepts of linear algebra, the point P'(x, y) = (-3, 4) represents the translation of P(x, y) = (-3, 4) along the vectors <7, -6> and <-1, 3>.

<h3>How to determine the resulting point by applying translations</h3>

Translations are a kind of <em>rigid</em> transformation. A transformation is <em>rigid</em> if and only if <em>Euclidean</em> distances are conserved. By linear algebra, an image as a consequence of <em>consecutive</em> translations is described by the following formula:

P' (x,y) = P(x,y) + \left(\sum\limits_{i=1}^{n}x_{i}, \sum\limits_{i=1}^{n}y_{i}\right)     (1)

Where:

  • P(x, y) - Original point
  • P'(x, y) - Image
  • \left(\sum\limits_{i=1}^{n}x_{i}, \sum\limits_{i=1}^{n}y_{i}\right) - Net translation vector

Now we proceed to determine the image of the given point:

P'(x, y) = (-3, 4) + (7, -6) + (-1, 3)

P'(x, y) = (-3 + 7 - 1, 4 - 6 + 3)

P'(x, y) = (3, 1)

By applying concepts of linear algebra, the point P'(x, y) = (-3, 4) represents the translation of P(x, y) = (-3, 4) along the vectors <7, -6> and <-1, 3>.

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream.She rows downstream miles/hour faster th
disa [49]

Answer:

Option D. 9 mi/hr downstream, 6 mi/hr upstream

Step-by-step explanation:

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

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3 miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way

Define the variables

Let

x -----> Alicia's rowing rate downstream in miles per hour

y ----> Alicia's rowing rate upstream in miles per hour

we know that

The rate is equal to the distance divided by the time

so

The time is equal to the distance divided by the rate

we have

\frac{6}{x}=\frac{4}{y}

4x=6y

x=1.5y -----> equation A

x=y+3 ----> equation B

equate equation A and equation B

1.5y=y+3

1.5y-y=3

0.5y=3

y=6

<em>Find the value of x</em>

x=1.5(6)=9

therefore

Alicia's rowing rate downstream is 9 mi/h

Alicia's rowing rate upstream is 6 mi/h

Plzzzz help me with this question ❓​
Elina [12.6K]

Answer:

i think u should first givr her discount by doing 20/100×3500=700 and than he will get 5 percent profit than here

3500-700=2800

now for 5 % profit

5/100*2800=140

hence

20% discount=700

5% profit =140

it might be wrong but here u go
