The answer is B by inspection, there really isn't any work to show. You could check every wrong answer to prove it's wrong but that's not needed.
Answer:
88
Step-by-step explanation:
Write the expression for the sum in the relation you want.
Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)
Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)
The relation we want is ...
Sn > 5543
35(1.06^n -1) > 5543 . . . . substitute for Sn
1.06^n -1 > 5543/35 . . . . divide by 35
1.06^n > 5578/35 . . . . . . add 1
n·log(1.06) > log(5578/35) . . . take the log
n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n
The least value of n such that Sn > 5543 is 88.
First distribute the negative. Then combine like terms. The answer should be 4ab+2a-7
Hello there,
I believe that the answer to your question is A.... I am not 100% sure tho!! Sorry if i am wrong!!
Hope I helped
Answer:
The value of n depends on the questin. N would be a variable in an equation.
Step-by-step explanation:
For example. 2*n=6
n is the variable in the equation. Therefore, the value of n is 3. Because 2*3=6.
