Answer:
$359.42
Step-by-step explanation:
The difference in the investment values can be computed by making use of the formulas for the account balance in each case.
compound interest: A = P(1 +r)^t . . . . interest at rate r compounded annually
simple interst: A = P(1 +rt) . . . . simple interest at rate r
__
The account earning simple interest will have a balance of ...
A = $8000(1 +0.12×3) = $10,880
The account earning compound interest will have a balance of ...
A = $8000(1 +0.12)^3 ≈ $11,239.42
The difference between the two investments is ...
$11,239.42 -10,880 = $359.42
Answer:
t=11.9
Step-by-step explanation:
960=420(2)^t/10
2.28571429=2^t/10
add log to both sides
log(2.28571429)=10
t log(2)
divide by log 2
1.19264508= 10
/t
10(1.19264508)
11.926450779=t
I think it’s A=B I could be wrong
Answer:
x = 2k
is the solution of this equation.
Step-by-step explanation:
This question is related to trigonometric equations.
The given equation is,
We have to find the solutions of this equation.
Put 
+ 3cosx - 1 = 2
= 0
For this equation only cosx = 1 is possible solution.
Cosx = 1 happens when x is a multiple of 2
So x = 2k is the solution of this equation.
