Altho' 2 is a factor of both 8 and 64, we cannot "find the value of 2" because that's already given.
I believe you may have meant "<span>Find the value of z in the following equation: 8z=64".
We can solve that equation for z: z = 64/8, or z = 8 (answer).</span>
Answer:
-1.2
Step-by-step explanation:

Subtract 3.9 from -9.18 to isolate the variable.

Divide -13.08 by 10.9

Which equals

The general formula for exponential growth and decays is:

if k>0 then then it is an exponential growth function. If k<0 then the function represents an exponential decay.
Now we need to classify each of the functions:
1.
The function

can be wrtten as:

comparing with the general formula we notice that k=2, therefore this is an exponential growth.
2.
The function

can be written as:

comparing with the general formula we notice that k=-4, therefore this is an exponential decay.
3.
The function

comparing with the general formula we notice that k=-1, therefore this is an exponential decay.
Answer:
Area = 140
16 x 8.75 = 140
Step-by-step explanation:
Answer:
1728
Step-by-step explanation:
There are 12 numbers that can be used for the first number; 12 for the second number; and 12 for the third number. This means there are a total of
12(12)(12) = 1728 combinations.
