Solve 3x²-x-2=0. Please show all work.​
lorasvet [3.4K]

3x²-x-2=0

Δ=1+24=25 (Δ=b²-4ac)

x₁,₂=\frac{1(+/-)\sqrt{25} }{6}

x₁,₂=\frac{1(+/-)5}{6}

x1=\frac{1+5}{6}=6/6=1

x2=\frac{1-5}{6}=\frac{-2}{3}

so

x1=1

x2=\frac{-2}{3}

A population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, which function represe
Dimas [21]

Answer:

P(t) = 258( 1 + 6%)^t

Step-by-step explanation:

Given that the  population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, the function representing the number of caribou in the forest in t years will be

P(t) = 258( 1 + 6%)^t

Since it is increasing, it will be 1 + 6%

Where P(t) is the function representing the population after t years.

258 is the current or initial population.
