Answer:
The characteristic of a logarithm is the number to the left of the decimal.
(The characteristic is like an exponent).
We are working with base 3 logs.
So if we are increasing a number by multiplying it by the base of the logarithm, (in this case 3 times 3) then we increase the characteristic by two.
Since 2 is the exponent of 3^2 then to get the log 3 of 72, we get the log3 (8) and increase it by 2.
1.8928 +2 = 3.8928
Had we been working with base 10 logs and we were multiplying a number by 100, We would increase the characteristic by 2 because 100 = 10^2.

Answer:
44, 21
Step-by-step explanation:
x+y = 2x-23
x-y = 2y - 19
Rewrite
-x + y = -23
x - 3y = -19
Use elimination.
Answer:
other parallel side is 23m
Step-by-step explanation:
Let's assume other parallel sides as 'x'
One of the parallel sides of the trapezium plot measure 18m
so, y=18
distance between the two parallel sides measure 20m
so, h=20
now, we can use area of trapezium formula

now, we can plug values

we can set A=410
and then we can solve for x




Answer:
