Answer:
a) 1,544,804,416
b) 52,523,350,144
c) 34
Step-by-step explanation:
(a) Each character position can be any of 24 letters or 10 digits, so any of 34 characters. The number of possible characters sets increases by a factor of 34 for each added character. A six-character plate will have ...
34^6 = 1,544,804,416 . . . possibilities
__
(b) 34^7 = 52,523,350,144 . . . possibilities
__
(c) 34^7/34^6 = 34 . . . times as many
This is the concept of application of compound interest, to calculate the amount I will have after the 5th deposit we proceed as follows;
A=p(1+r/100)^n
where;
A=future amount
p=principle
r=rate
n=number of years
thus substituting the values in our formula we get:
A=3,100(1+8.5/100)^5
A=3,100(1+0.085)^5
A=3100(1.085)^5
A=4,666.34
The amount of money after 5 years will be $4,666.24
Answer:
1) -5 and +5; 2) -9 and +9
Step-by-step explanation:
1) a² + 2ab + b² = 25
(a + b)² = 25 Wrote the left-hand side as a square
a + b = ±5 Took the square root of each side
All values of a + b are -5 and +5.
2) a² − 8ab + 16b² = 81
(a - 4b)² = 81 Wrote the left-hand side as a square
a - 4b = ±9 Took the square root of each side
All values of a - 4b are -9 and +9.
