You have to get X all by itself so you divide 20 and 30 which gives you a fraction. X= 20/30
Then = 2/3

Answer:

V= -2000t + 20000

Step-by-step explanation:

Let m be the slope of our function :

m=(20000-16000)/(0-2)= -2000
so our function is V= -2000t + b
b is the intitial price so b = 20000
then : V= -2000t + 20000

Let's check :

take the second year : V= -2000*2 +20000 = 16000
that's true !

A population, P(t) (in millions) in year t, increases exponentially. Suppose P(9)=16 and P(18)=24. a) Find a formula for the pop

jenyasd209 [6]

Answer: $\frac{32}{3}\left ( 1.0460\right )^t$

Step-by-step explanation:

Given

Population changes exponentially

$P\left ( t\right )=ab^t$

$P\left ( 9\right )=16$ ------1

$P\left ( 9\right )=16=ab^8$

$P\left ( 18\right =24=ab^{18}$ -----2

divide 1 & 2 we get

$\frac{24}{16}=\frac{b^{18}}{b^9}$

$\frac{3}{2}=b^9$

Substitute $b^9$ in 1 we get

$a=\frac{32}{3}$

Thus $P\left ( t\right )=\frac{32}{3}\left ( 1.0460\right )^t$
