The population of a city is growing at an average rate of 3% per year in 1990 the population was 45 000.

Nonamiya [84]

This is an exponential growth/decay problem...

F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case:

F=I(1.03)^t and they just want to know when F=2I so

2=1.03^t take natural log of both sides...

ln2=t*ln1.03

t=ln2/(ln1.03)

t≈23.45

So it will take approximately 23.45 years for the population to double..

1990+23.45=2013.45

So during the year of 2013 the population will have double from its 1990 level.

PLEASE HELP HYPERBOLAS What is the length of the transverse axis ?<br> (x-1)^2/25-(y+3)^2/9=1

Sav [38]

Given equation of hyperbola is

$\frac{(x-1)^{2}}{25}-\frac{(y+3)^{2}}{9}=1$

Given hyperbola is the horizontal hyperbola

The standard form of the horizontal hyperbola is

$\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}}=1$

When we compare these two equations, we get

h = 1, a = 5 , k = -3 and b = 3

Length of the transverse axis = 2a

Plug in the value of 'a' as 5

So,Length of the transverse axis = 2(5) = 10
