Answer:
= 0.99
Step-by-step explanation:
Convert the tax rate from a percent to a decimal number by moving the decimal point 2 places to the left.
8.8% = 0.088
Now multiply the price of the item by the tax rate:
63 x 0.088 = 5.544
Now round that to the nearest cent = $5.54
The population triples ( P × 3 ) every ten minutes...
So if ten minutes is reached there will be 1,200 bacteria.
Edited - missed the question
** The units for time should be in minutes.
P = 400 × 3^(t/10)
at t = 0 ; P = 400
at t = 10 ; P = 1,200
When P = 600
600 = 400 × 3^(t/10)
6/4 = 3^(t/10)
Log(3/2) = Log(3^(t/10))
power rule
Log(3/2) = (t/10) Log(3)
10 × Log(3/2)/Log(3) = t
3.69 minutes the population will be at 600 bacteria
Unites for time are in minutes.
Sqrt(-2), can be written as i * sqrt(2). Thus, our answer is x - i sqrt(2).
