Y = log3 27
27 = 3^x
3^3 = 27
so x = 3
Answer:
C a1= -2
an = an-1 +3
Step-by-step explanation:
an = -2+ (n-1)3
What is the first term? Let n=1
a1 = -2 + 0*3
a1 = -2
The difference between the terms is +3 (coefficient on (n-1))
The second term is the first term +3
The third term is the second term plus 3
The next term is the previous term +3
so an = an-1+ 3
Answer:
6
9
6.48
Step-by-step explanation:
this is the easiest way to solve for percentage:
Where all the percents (except 100) would go in part
and the whole number would go in whole
Then multiply 24 × 25 ÷ 100 = 6
Multiply 60 by 25 then divided by 100 = 9
Then for the last one 9 is what percent of 72
all we have to do is multiply 9 and then convert 72 into a decimal (0.72)
Then 9 × 0.72 = 6.48
