Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
Answer:
x = -1
Step-by-step explanation:
log(-2x+9)= log(7-4x)
becomes:
-2x + 9 = 7 - 4x as long as these are not negative
2x + 9 = 7
2x = -2
x = -1
check
-2*(-1) + 9 = 2 + 9 = 11
ok
