Step-by-step explanation:
Answer: After 7 years the population will be one-half the initial amount.
Step-by-step explanation:
Given: Initial population = 500,000
The population declines according to the equation:
, where P is the population in t years later.
One-half the initial amount = 0.5 x 500,000
= 250,000
Put P(t)=250,000, we get

Hence, After 7 years the population will be one-half the initial amount.
Answer:
4 ft by 12 ft
Step-by-step explanation:
x^2 +8x -48
Set this equal to 0 to solve for the values of x
x^2 +8x -48=0
What two values multiply to -48 and add to 8
12*-4 = -48
12+-4 = 8
(x+12) (x-4) = 0
Using the zero product property
x+12 = 0 x-4=0
x=-12 x=4
We cant have a negative length
x=4
The area is 48
48/4 = 12
The other dimension is 12
