Answer:
2x -3y = 21
Step-by-step explanation:
The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.
3x +2y = 6 . . . . . given equation
2x -3y = c . . . . . . coefficients swapped, one negated
2(6) -3(-3) = c = 21 . . . . . the value of c for the given point
The desired equation is ...
2x -3y = 21
Answer:
the balance after 5 years is: 26540.744
Step-by-step explanation:
Given the information:
- P = initial balance = $ 20,000
- r = interest rate (decimal) = 5% = 0.05
- n = number of times compounded annually = 4
- t = time = 5
We have the compound interest function ta model the situation is:
<=> A =
<=> A = $26540.744
Hence, the balance after 5 years is: $26540.744
