Answer:

x =  - 4, \:  \: x = 1 \frac{1}{2}

Step-by-step explanation:

2 {x}^{2}  + 5x - 12 = 0 \\  \\ 2 {x}^{2}  + 8x - 3x - 12 = 0 \\  \\ 2x(x + 4) - 3(x + 4) = 0 \\  \\ (x + 4)(2x - 3) = 0 \\  \\ x + 4 = 0, \:  \: 2x - 3 = 0 \\  \\ x =  - 4, \:  \: x =  \frac{3}{2}  \\  \\ x =  - 4, \:  \: x = 1 \frac{1}{2}

A population of 100 frogs increases at an annual rate of 22%. How many frogs will there be in 5 years? Write an expression to re
gizmo_the_mogwai [7]
Exponential growth of the form:

F=Ar^t

F=100(1.22)^t

F(5)=100(1.22)^5

F(5)=270.27

F(5)=270 to the nearest frog...

....

1.22=r^12

r=1.22^(1/12)

F=100(1.22^(1/12)^t)

F=100(1.22^(t/12))  now it will produce monthly populations...

Say we did the same as before but instead of 5 years you have 60 months...

F(60)=100(1.22^(60/12))

F(60)=270 to the nearest frog... :P
