Answer:

Question 1:  Slope = \frac{1}{3}  feet

Question 2:  Slope = 4

Step-by-step explanation:

Question 1:

The pitch of a roof is the inclination of that roof. The "slopiness" of the roof. Whether it is steep or not.

To know the pitch, we need to find the "RISE" over "RUN". That means the "height" from ground and the "length" from initial position.

The height is shown in the figure as 4 ft

The length is shown in the figure as 12 ft

The slope is the quotient of it.

Hence,

Slope = 4/12 = 1/3 feet

Question 2:

To find slope from table of points, we need 2 coordinate pairs in the form (x,y). Lets take the first two points.

(1,2)

and

(3,10)

The slope would be the change in y coordinates of both (2nd point y coordinate - 1st point y coordinate) DIVIDED by the change in x coordinates of both (2nd point x coordinate - 1st point x coordinate). So:

Change in y coordinates = 10 - 2 = 8

Change in x coordinates = 3 - 1 = 2

Thus,

Slope = change in y/change in x = 8/2 = 4

Slope = 4

Find the value of the following expression below 8(15-4)/4^2-5
Sonja [21]

Answer:

The correct answer is 1/2 or 0.5

Step-by-step explanation:


8(15-4)/4^2-5

8(11)/4^2-5

Now i'm going to multiply 8 by 11

88/4^2-5

Now solve 4^2

Which is 16.

Now we have 88/16-5

Divide 88 and 16 which is 5.5.

Now minus 5.5 - 5 which gets us our answer: 0.5

Find the length of the altitude to the hypotenuse. Round the answer to the nearest tenth, if needed.
SVEN [57.7K]
To solve this, it might be easier to draw it out (see the picture below). I split it into two triangles and used trig functions to find the altitude. I used the big triangle to find theta, and the used theta to find the side of the altitude. *remember that sine= opposite/hypotenuse*
