(7,-1) and ( 21,-5) what is the slope

Mathematics
1 answer:
mart [117]3 years ago
8 0

Answer:

-2/7

Step-by-step explanation:

Going from (7,-1) to ( 21,-5) we see x (the 'run') increasing by 14 and y (the 'rise') decreasing by 4.  Thus, the slope of the line connecting these two points is m = rise/run = -4/14, or -2/7.

See below for the domain and the range of the functions.

<h3>How to determine the domain and the range?</h3>

As a general rule, all linear functions have a domain and a range of all set of real numbers i.e.  (−∞, ∞)

The functions (2), (3), (4), (5) and (6) are linear functions.

So, their domain and range are  (−∞,∞)

For function (1), we have:

f(x) = 3(3)^x - 1

The above is an exponential function.

The domain of an exponential function is all set of real numbers i.e.  (−∞, ∞)

I need help finding the area and the equation to it.
RideAnS [48]

Hello from MrBillDoesMath!


Answer:

3 1/2   (i.e 3.5)


Discussion:

From the attached file, the area of the shaded triangle =

Area  =   <u>square</u> surrounding triangle -

               area triangle 1 - area triangle  2 -  area triangle 3


         = 4 * 4  -

             (1/2) (1 * 1)     -  (1/2) (3 * 4)  -   (1/2) (3 * 4)

         = 16  - 1/2 - 1/2 (12) - 1/2(12) =

         = 16 - 1/2 - 12 =

         = 4 - 1/2

         = 3 1/2


Where we have used that the area of a triangle =

(1/2) base * height.


Thank you,

MrB

The Pyramid Arena is located in Memphis, Tennessee. It is in the
natta225 [31]

Answer:

528000 ft²

Step-by-step explanation:

The Pyramid Arena has a shape of a square pyramid. A square pyramid is a pyramid with a square base and the top point is directly above the center of the base. It consist of 5 faces (base and 4 triangles), 8 edges and 5 vertices.

Given:

length of base (b) = 600 ft and height of lateral face (h) = 440 ft.

Since the lateral faces are made of glass, the area of each lateral face is the same as the area of a triangle with base same as base length and height same as height of lateral face.

Therefore, area of each lateral face = 1/2 × b × h = 1/2 × 440 × 600 = 132000 ft²

The lateral faces are made almost  completely of glass and they are 4 lateral faces, therefore the total  area of the glass in the Pyramid Arena = 4 ×  132000 ft² = 528000 ft²
