Answer:

9) The scale factor is 3/2

10) The scale factor is 4/3 and the missing length is 9

Step-by-step explanation:

9) The triangles are similar because 6/4 = 9/6 = 3/2

The scale factor is 6/4 = 3/2

10) If the rectangular gardens are similiar then the scale factor is 16/12 = 4/3

(The scale factor is always > 1)

=> 12 / x = 4/3 => 4x = 12·3 => x = 9

Answer:

9. The scale factor is 1.5.

10. scale factor = 0.75

    the missing side is 9m

9. 3/2 = 1.5

   9/6 = 1.5

   6/4 = 1.5

10. 12/16 = 0.75

    12*0.75 = 9

Please help asap. it’s 2 am and idk how to do this

This is an example of a piecewise defined function. It means that the function has not a unique formula to represent it, but it depends on "where" you want to compute it.

So, if you choose any input x, you have two alternative:

  • If x \neq 3 (i.e., if you've chosen any input that is not 3), the output will be the opposite of the input you've chosen (y=-x)
  • If x=3, the ouput will be -1.

So, let's forget about x=3 for a moment. For any input x you choose, the answer is -x. The graph of this function is the bisector of the second and fourth quadrant.

Now remember that there is our special case: you have to "carve a hole" in our line, at x=3, and assing to this point the value -1, instead of what we would expect, i.e. -3.

So, the graph of this function is the line y=-x, except for one point (x=3), where we reassign the value to be -1.

using the 28/36 ratio, determine the maximum allowable recurring debt for someone with an annual income of $86,250.
murzikaleks [220]
Given:
28/36 ratio
annual income: 86,250

28+36 = 64

28/64 * 86,250 = 0.4375 * 86,250 = 37,734.375
36/64 * 86,250 = 0.5625 * 86,250 = 48,515.625

28/36 ⇒ 37,734.375/48,515.625

How do you write 0.0000006813 in scientific notation?
Free_Kalibri [48]

Answer:

6.813·10^7

Step-by-step explanation:

Multiplying 0.0000006813 by 10^7 will move the decimal point 7 places to the right, resulting in 6.813.

Conversely, multiplying 6.813 will move the decimal point 7 places to the left, producing the original decimal fraction.

Therefore,

0.0000006813 = 6.813·10^7
