1 Solve for t write your asnwer in interval notation t2t3 t

1) Solve for t. write your asnwer in interval notation t-2/t+3 <0

2) what kinds of symmetry if any does the graph of 2x^2 - 5xy +Y^2=0

3) how long will it take for $8,200 to grow to $12,00 at an interest rate of 1.2% if the interest is compoinded continuously? round the of years to the nerest hundredth.

Solution

1) t-2/t+3 <0 ======> t - 2 < 0 =======> t < 2

2) 2x^2 - 5xy + Y^2 = 0 [neither even nor odd]

3) A = P*e^(nt)

12000 = 8200*e^(0.012*t)

t = 31.73 years
