Answer:
no proportional.if it was proportional it would start at (0,0)
To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:

Answer:
An old bone contains 80% of its original carbon-14 in 1844.6479 years
Step-by-step explanation:
We know that
half life time of C-14 is 5730 years
so, h=5730
now, we can use formula

we can plug back h
and we get

An old bone contains 80% of its original carbon-14
so,
P(t)=0.80Po
we can plug it and then we solve for t





So,
An old bone contains 80% of its original carbon-14 in 1844.6479 years

Answer:
Second option is correct

Step-by-step explanation:
Given:
Central angle = 15°
Radius of the circle = 9 in
Arc length = ?
Given formula is

Where n is the central angle of the sector.
Write the given formula for Arc length of the sector.

We know that the the circumference of the circle is
, where r is the radius of the circle,

Now we substitute central angle value and radius value in above equation.


----------(
)

Divide the numerator and denominator by 5.

Therefore the arc length of the sector is
