Answer:

\frac{3}{5}

Step-by-step explanation:

Let the side length for the octagon having 9m² as area = x

Side length for the octagon having area of 25m² = y.

Thus:

\frac{9}{25} = (\frac{x}{y})^2 (area of similar polygons theorem)

The scale factor of their sides would be \frac{x}{y}. Which is:

\sqrt{\frac{9}{25}} = \frac{x}{y}

\frac{\sqrt{9}}{\sqrt{25}} = \frac{x}{y}

\frac{3}{5} = \frac{x}{y}

Scale factor of their sides = \frac{3}{5}

Which statement is true about the function f(x) = 7
TEA [102]

Answer:

the function is EVEN because f(x)= f(-x)

Step-by-step explanation:

Key to find if a function f(x) is even or odd is to replace the x with -x

if the results comes out to be f(x) then it is even function

if the results comes out to be -f(x) then it is odd function

where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.

In given case f(x)=7

if we replace x with -x in above equation then results is 7

f(-x)= 7

hence f(x)= f(-x) = 7

The slant height is used to find the volume of a square pyramid. true or false
alexandr1967 [171]
The answer is false.

For a square pyramid, the volume is calculated by 1/3*B*h. The height should touch the tip and lie perpendicular to the base. Slant height is used for surface area, not volume.

Find the slope of the line. (Please explain if you can, and answer in an integer/fraction.)
Setler [38]

Answer:

-2

Step-by-step explanation:

We can find the slope of a line by using two points

(-2,1) and (2,-7)

The slope is given by

m = (y2-y1)/(x2-x1)

   = (-7-1)/(2- -2)

   = (-8)/(2+2)

   = -8/4

   =-2
