Answer:
B. about 76 in 2
Step-by-step explanation:
The picture of the question in the attached figure
I will assume that the tile is a regular hexagon
The area of the regular hexagon is equal to the area of six congruent equilateral triangles
Applying the law of sines to calculate the area of triangle
Remember that the measure of the interior angle in a equilateral triangle is 60 degrees
so
substitute
therefore
The area of each tile is about 76 square inches
Answer:
-Exponential Decay
-Decay factor is (1-0.05)
Step-by-step explanation:
-Given that the number decreases by a defined rate each year from the initial size by 5%,
-This is an exponential decay function of the form:
Where:
is the quantity/size after time t
is the initial size
is the rate of decay
-Our function can the be written as
Hence, the decay rate/factor is 0.05
#Alternatively
The exponential decay can be of the form:
Where:
y is the size at time x, a is the initial size, x is time and b is the decay factor.
b is of the form
Hence, the decay factor is (1-0.05)
