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%.

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° .....
X - y = -3
x - x - y = -3 - x
-y = 3 - x
y = -3 - x
