Answer:
8
Step-by-step explanation:
the average of 9, 8 , and 7 is 8
{k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64}
{k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}
{(k - 4)(k + 6) = 0, (k - 7)(k + 9) = 0}
{k = -6, 4, -9, 7)
Therefore, range = {-9, -6, 4, 7)
Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%
