28x - 2 = 26x + 6
2x = 8
x = 4
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:L=4 W=15
Step-by-step explanation:
P=2L+2W
38-8=30
If length is 8 less than twice the width and the perimeter is 38, then subtract 38-8 which is 30, then divide 30 by 2 to get 15.
P=2(4) +2(15)
P=38
THEN, LENGTH OF THE HYPOTNUSE IS 5 FEET.
