Answer:
log(13/4)
Step-by-step explanation:
The property of logarithms of interest here is ...
log(a) + log(b) = log(ab)
Using a=13/5 and b=5/4, we find ...
log(13/5) + log(5/4) = log((13/5)(5/4)) = log(13/4)
1.75-1.25=0.5, prices increased by $0.5
X% of 1.25 is 0.5. X% *1.25=0.50
X%=0.5/1.25=0.4
Price increased by 40%
Answer:
f(x) = 4x² + 9x - 28
Step-by-step explanation:
Create the polynomial by multiplying (4x - 7) and (x + 4) together:
f(x) = 4x² + 16x - 7x - 28, or
f(x) = 4x² + 9x - 28
