Make an equation.
80% = 0.8
'of' is multiplication
'what number' is 'x'
'is' is an equal sign
0.8 * x = 64
0.8x = 64
Divide 0.8 to both sides:
x = 80
Let's consider the scenario after each year:
After the zeroth year, the population is: 120 000(1 + 0.04)⁰
After the first year, the population is: 120 000(1 + 0.04)¹
After the second year, the population is: 120 000(1 + 0.04)²
...
Thus, we can find the general rule:
After the nth year, the population is: 120 000(1 + 0.04)ⁿ
And after the 16th year, the population is 120 000(1 + 0.04)¹⁶ = 224 758 (rounded to nearest whole number)
Answer;
A) y=8x
step by step explain action;
48 = 8(6)
48=48
The 4th term of the sequence is -38
Given the following recursive function 
and, 
, we need to get the fourth term of the sequence:
For the second term:
a2 = -2a1 - 2
a2 = -2(4) - 2
a2 = -8 - 2
a2 = -10
For the third term:
a3 = -2a2 - 2
a3 = -2(-10) - 2
a3 = 20 - 2
a3 = 18
For the fourth term:
a4 = -2a3 - 2
a4 = -2(18) - 2
a4 = -36 - 2
a4 = -38
Hence the 4th term of the sequence is -38
