A jogger ran 3 miles due east of his house. then he ran 5 miles at a heading of 30o east of north (or 30o ne). how far is he fro

Magnitude of the net displacement: 7.0 miles

Step-by-step explanation:

In order to find the total displacement of the man, we have to resolve each displacement along the x- and y- direction.

Taking x as positive x direction and y as positive north direction:

- The first motion is 3 miles due east, so

$A_x = 3 mi\\A_y = 0$

- The second motion is 5 miles at $30^{\circ}$ east of north, so:

$B_x = 5 sin 30^{\circ}=2.5 mi\\B_y = 5 cos 30^{\circ}=4.3 mi$

So the components of the net displacement are

$R_x = A_x + B_x = 3 + 2.5 = 5.5 mi\\R_y = A_y+B_y = 0 + 4.3 = 4.3 mi$

And so the magnitude of the net displacement is

$d=\sqrt{R_x^2+R_y^2}=\sqrt{5.5^2+4.3^2}=7.0 mi$

So, he is 7.0 miles far from the house.

A phone company offers two monthly plans. Plan A costs 14 plus an additional 0.09 for each minute of calls. Plan B costs 18 plus

Sliva [168]

Answer:

200 minutes

Step-by-step explanation:

14 + 0.09 x = 18 + 0.07 x

0.09 x - 0.07 x = 18 - 14

0.02 x = 4

x = 400/2 = 200

I need the answer to number 6 & 7 please

zlopas [31]

6.
$k=\dfrac{y}{x}\\
k=\dfrac{25}{1}=25 \Rightarrow H$

7.
$\dfrac{118}{13}=\dfrac{59}{z}\\
118z=767\\
z=\dfrac{767}{118}=0.6$
