Answer:

Step-by-step explanation:

y = (-1/4)x - 4 has a y-intercept of (0, -4). Place a dark dot at (0, -4).

Now we use the info from the slope, -1/4:

Starting with your pencil point on the dot (0, -4), move the pencil point 4 units to the right and then 1 unit down. You will now be at (4, -5). Place a dark dot there.

Then draw a straight, solid line through (0, -4) and (4, -5).

In the problem 4x + 10 list a term, factor, coefficient, and constant.

kifflom [539]

term- 4x and 10

This is because to be a term it has to be + or -

Factor- 4x+10

This is because that is what is happening in the problem

Coefficient- 4y

I don't know what the constant would be, But I hope that this helps you

From the side of a hill wai-kin looks up at the top of a nearby vertical cliff at an angle of elevation of 36 degrees and looks

oksano4ka [1.4K]

Answer:

881.5 meters.

Step-by-step explanation:

The horizontal plane at the level of wai-kin's eyes divide the height of the cliff into two parts. Let the upper part be represented by x and the lower part be represented by y.

The height of the cliff = x + y

Applying the appropriate trigonometry functions.

To determine the value of x;

Tan θ = $\frac{opposite}{adjacent}$

Tan $36^{o}$ = $\frac{x}{490}$

⇒ x = 490 x Tan $36^{o}$

= 490 x 0.7265

= 355.985

x = 356 meters

To determine the value of y;

Tan θ = $\frac{opposite}{adjacent}$

Tan $47^{o}$ = $\frac{y}{490}$

⇒ y = 490 x Tan $47^{o}$

= 490 x 1.0724

= 525.476

y = 525.5 meters

Therefore,

The height of the cliff = x + y

= 355.985 + 525.476

= 881.461

The height of the cliff is 881.5 meters.
