v = -20
you may replace v with -20 and simplify to vertiy the answer.
Answer:
log 12 = 1.0791
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the logarithmic function is log12
We will apply the formula
log by = log b + log y
log xⁿ = n log x
<u><em>Step(ii):-</em></u>
log 12 = log 4 × 3
= log 4 + log 3
= log 2² + log 3
= 2 log 2 + log 3 (∵ log xⁿ = n log x)
= 2× 0.3010 + 0.4771
= 1.0791
It is B and C. The answer is B and C or B and D

Answer:
$1.8
$2.25
$0.45
Step-by-step explanation:
a)
Unit Price = Cost/Volume
= 9/5
= $1.8/Kg for the 5Kg
4.5/2
= $2.25/Kg for the 2Kg
b)
($2.25-$1.8) per kg
= $0.45
