<h2>Answer:</h2>

B. |y| = 1.6

<h2>Step-by-step explanation:</h2>

A sketch of the vector is attached to this response.

As shown, the vector lies on the second quadrant and its horizontal and vertical components are given by x and y respectively.

Where;

|x| = v cos θ              -----------------(i)

|y| = v sin θ               -----------------(ii)

and

v = magnitude of the vector = 2.5km/hr

θ = angle that the vector makes with the +x axis = 90° + 50° = 140°

<em>To get the magnitude of the vector's vertical component</em>

<em>Substitute these values into equation(ii) as follows;</em>

|y| = 2.5 sin 140°

|y| =  2.5 x 0.6428

|y| = 1.607

|y| ≅ 1.6 km/hr

Therefore, the vertical component of the vector has a magnitude of 1.6 km/hr.

$12.95 for 3 pounds of nuts or $21.45 for 5 pounds of nuts
Zarrin [17]

First, find the base rate of both of the numerals, to do this simply divide the price by the number of units.

12.95 divided by 3 is 4.32 ( rounded to nearest cent )

21.45 divided by 5 is 4.29 ( rounded to nearest cent )

So, if you want the better deal ( which is what I've interpreted ), then 5 pounds of nuts is the better deal <u>BY</u> 3 cents.

Hope this helps, if not, comment below please!!!!

Am I correct? (Perfect Square Form)
natka813 [3]

Answer:

(x -3 )^2 = 10

Step-by-step explanation:

Given

x^2 - 6x - 1 = 0

Required: Express as a perfect square

x^2 - 6x - 1 = 0

Add 10 to both sides

x^2 - 6x - 1 +10= 0+10

x^2 - 6x +9= 10

Expand

x^2 - 3x  - 3x+9= 10

Factorize:

x(x - 3) - 3(x  - 3)= 10

Factorize:

(x -3 )(x - 3) = 10

(x -3 )^2 = 10
