You want to find t such that
2 = 1·e^(0.082t)
ln(2) = 0.082t . . . . . take the natural log
ln(2)/0.082 = t ≈ 8.453
It would take about 8.5 years for a population to double at 8.2% per year.

p + m - 10 is your expression
Step-by-step explanation:
Answer:
Second option: 4 cm and 7 cm.
Step-by-step explanation:
A Parallelogram is defined as a type of Quadrilateral, whose opposite sides are parallel and have equal lenght.
Since the opposite sides
and
have the same lenght, then:

Now you have to solve for "n":
Add 6 to both sides of the equation.
Subtract 3n to both sides of the equation:

Divide both sides of the equation by 2:

To know the lenght of two adjacent sides, susbtitute
into the third side
and into one of the the sides that are opposite to eache other. Then:

Answer:
Step-by-step explanation:
y + 2= -1/2(x - 0)
y + 2 = -1/2x + 0
y = -1/2x - 2
-1/2x = -2
x = 4
