They are perpendicular

The slopes of two perpendicular lines is when the two lines are negative reciprocals of each other.

Slope of a:

1 - -3
_____ = 4/10
5 - -5

Slope of b:
-6 - 4
_____ = -10/4
2 - -2

So yes.

(b) 5.2m + 5 = 2.9m – 3 – 4.1m

ohaa [14]

Answer:

m =-1.25

Step-by-step explanation:

5.2m + 5 = 2.9m – 3 – 4.1m

Combine like terms

5.2m + 5 = -1.2m – 3

Add 1.2m to each side

5.2m +1.2m +5 = -1.2m +1.2m -3

6.4m +5 = -3

Subtract 5 from each side

6.4m +5-5 = -3-5

6.4m = -8

Divide each side

6.4m/6.4 = -8/6.4

m =-1.25

Sam sees a rocket traveling straight up at an angle of elevation of 24 degrees. If Sam is located 5 miles from the rocket Launch

julsineya [31]

Given :

Angle of elevation, Ф = 24°.

Distance of Sam from launchpad, D = 5 miles.

To Find :

How high is the rocket.

Solution :

Let, height is h.

We know, tan Ф is given by :

$tan \ \phi=\dfrac{h}{d}\\\\tan \ 24^{\circ}=\dfrac{h}{5}\\\\h = 5\times tan \ 24^{\circ}\\\\h = 2.226 \ miles$

Hence, this is the required solution.
