The population of Bridgetown triples every decade. If the population

Afina-wow [57]

Between 2000 and 2030 three decades will have gone by, which means the population will triple three times.

$2000-25,000 \\ 2010-25,000*3=75,000 \\ 2020-75,000*3=225,000 \\ 2030-225,000*3=675,000$

Therefore, the population of Bridgetown will be 675,000 people in 2030.

What is the inverse of the function F(x)= 19/x^3?

AleksAgata [21]

set f(x) equal to y

y = 19/ x^3

swap x and y

x = 19/y^3

make y the subject

xy^3 = 19

y^3 = 19/x

$y = \sqrt[3]{ \frac{19}{x} }$
