-2x+8y-4 *parallel *perpendicular *neither *please help asap!*

guapka [62]

Answer:

Step-by-step explanation:

y = m x + b

Then we can read the slope right off the equation: it is the number

represented by m.

I'll help you get one into this form:

Start with -2x+8y-4

Then add 4 to both sides: -2x+8.

Then divide both sides by 4: y = 3/4 x + 6/4.

This means that the slope is 3/4.

Try the other one on your own and reduce the slope to the smallest

possible fraction.

Now, what does this mean? If the slopes are the same, it means the two

lines are parallel. If one slope is the negative reciprocal of the

other, then the two lines are perpendicular. To get the negative

reciprocal of a number, put one over the number and then make it

negative. So:

if the number is its negative reciprocal is

2 -1/2

3/10 -10/3

-3/2 2/3

So if the two lines had these respective slopes, they would be

perpendicular.

If the slopes are neither the same nor negative reciprocals, the lines

are neither parallel nor perpendicular.

Jon is in a raft 100m from the base of a 54m cliff. What is the angle of depression from the he top of the cliff to the raft? Le

kvv77 [185]

Answer:

28.4 degrees

Step-by-step explanation:

In the diagram attached

Height of the cliff, AB=54 m

Distance of the raft to the base of the cliff, AC=100m

We want to determine the angle of depression from the top of the cliff to the raft. This is angle OBA.

$\angle OBA = \angle BAC $ (Alternate Angles)\\Therefore, in the right triangle ABC\\\tan A =\dfrac{BC}{AC}\\ \tan A =\dfrac{54}{100}\\\tan A =0.54\\A=\arctan 0.54\\A=28.4^\circ$ (to the nearest tenth)$

The angle of depression from the top of the cliff to the raft is 28.4 degrees correct to the nearest tenth.
