The value of w given that k is 15 is 30

<h3>Sum of vectors</h3>

From the given diagram, the sum of the two vectors moving in the same direction is equal to the vector moving in the opposite direction.

The sum of vectors in similar directions = -k% - k%
The sum of vectors in similar directions = -2k%

Equating this to -w%

-2k% = -w%

-2k = -w

w = 2k

If k = `5

w = 2(15)

w = 30

Hence the value of w given that k is 15 is 30

1) Draw the coordinate plane

2) Draw the line y = - 2

It is a line parallel to the y axis, two units below the origin

3) The solution (graph of the inequality y < - 2) is all the area below the line y = - 2.

Varvara68 [4.7K]

<u>Answer: </u>

The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.

<u> Solution: </u>

Given that current population of city is 27900.

Also, population of a city has decreased by 38% since it was last measured.

Let assume that population of city when it was last measured = x

Decreased of 38% means x-38% of x . we can write this as,

$=x-\frac{38}{100} \times x$
