Answer: <em>Yes</em>, a coefficient can have two variables.
A is the initial population
b is the decay coefficient
X is normally the time.
<span>then is the population half of the initial population of A
for half life you will have
</span>
<span>so the equation becomes

Bottom Side Surface Area:
(24 inches + 24 inches + 24 inches) * (30 inches)
= 72 inches * 30 inches
= 2160 inches squared
--------
Top Side Surface Area:
24 inches * 30 inches
= 720 inches squared
--------
Length of the diagonal (D) which needs to be measured:
*Use Pythaogras's theorem...
24^2 + 10^2 = D^2
D=√(24^2+10^2)
D=26 inches
------------
Measure the surface area of the two ramps:
26 inches * 30 inches * 2
= 1560 inches squared
-----------
Total surface area:
2160 inches squared + 720 inches squared + 1560 inches squared
= 4440 inches squared
---------
Answer:
4440 square inches
<h3>
Answer: Choice A. 8pi feet</h3>
======================================================
Explanation:
The perimeter around the circle is known as the circumference
The full circumference of a circle with radius r is
C = 2*pi*r
In this case, r = 16 is the radius, so,
C = 2*pi*r
C = 2*pi*16
C = 2*16*pi
C = 32pi
is the full distance around the circle. But we only want 90/360 = 1/4 of that total distance. So take 1/4 of 32pi to get
(1/4)*32pi = (1/4*32)pi = 8pi
The arc length is exactly 8pi feet long
Approximately this is about 25.13274 feet
