Answer:ayayaa
Step-by-step explanation:
So since -2, 0, 1 are the roots:
Therefore x = -2, x = 0 , x = 1
Implies that:
x = 2 x - 2 = 0
x = 0 x = 0
x = 1 x - 1 = 0
Therefore (x - 2)x(x - 1) = 0
(x - 2)(x - 1) = x(x - 1) - 2(x - 1) = x² - x - 2x + 2 = x² - 3x + 2
(x - 2)x(x - 1) = 0
(x - 2)(x - 1)x = 0
(x² - 3x + 2)x = 0
x*x² - x*3x + x*2 = 0
x³ - 3x² + 2x = 0
This is the polynomial with the least degree, because it possible for another polynomial with higher power to still have the same root.
x³ - 3x² + 2x = 0 is the polynomial.
I hope this helps.
Answer:
<em>is the increased number.</em>
Step-by-step explanation:
<em>The first step would be to turn the percentage into a decimal. To do that, divide it by 100.</em>

Then, multiply that by 90.

Add both together to get the increased price.

Answer:
25.2 weeks until everyone on the planet is infected
Step-by-step explanation:
The number of infected people after t weeks has the following format:

In which P(0) is the initial number of infected people and r is the growth rate, as a decimal.
The number of infected people doubles every week
This means that 
So




So

200-person town
This means that 
So


How long will it be until everyone on the planet is infected?
This is t for which P(t) = 7700000000[/tex]
So







25.2 weeks until everyone on the planet is infected
