Yeap, number 6 is growing the fastest, because 1.189 is the largest of the growth factor, now that's just the growth factor, no the growth rate.

growth rate will be 1.189 - 1, or 0.189, in decimal format, let's put it in percentage format, 0.189 * 100, or 18.9%.

and yes, you're correct again, 3 is shrinking fastest, because 0.78 is the smallest growth factor, so its growth rate is

0.78 - 1, or -0.22, is a negative rate, so if we put in decay term is just 0.22 in decimal format, let's put it in percentage format

0.22 * 100, or 22%.

HELP QUICK PLEASE! 20 POINTS
victus00 [196]

Answer:

54%

Step-by-step explanation:

Percent increase = (new - original)/ original  * 100%

The new cost is 800 and the original cost is 520

Percent increase = (800-520)/520 *100%

                             = 280/520 * 100%

                              .538461538 * 100%

                               53.8461538 %

 Give the answer to 2 significant figures, means we round to the ones place

                                 54 %

Answer:

steps below

Step-by-step explanation:

Are you going to solve the value of A or just a proof the equation

cos 2A = cos² A - sin² A

2cos²A-cos2A-1 = 2cos²A - (cos² A - sin² A) - 1 = cos² A + sin² A - 1

2cos²A-cos2A-1 = 1 - 1 = 0

A: 90° or 270° or 450° .....
