The eccentricity of an eclipse is found by using the
formula, eccentricity = c/a
Where,
c represents the distance between the center and a focus.
a represent the distance between that focus and a vertex
The numerical value of the eccentricity of an eclipse ranges
between 0 and 1
Step-by-step explanation:
five-eighths means 5/8
one third means 1/3
the difference between 5/8 and 1/3 is
Answer: 1/(Y^2) or if you want in y^n is y^2
apply exponents law (a^b) ^c = a^b c
take off the parenthesis
1/2 · 4
1 · 4/(2)
4/2
divide it
4/2= 2, nevertheless it become -2
y^-2
1/(y^2)
First, you have to find the area of the entire wall, including the window. The formula for the area of a trapezoid is:
A = (b1 + b2)/2 * h
b1 is the first base, b2 is the second base, A is the total area, and h is the height.
Plug in the numbers from the problem.
(13 + 10)/2 * 8
Simplify.
(23)/2*8
11.5*8 = 92
Now, to calculate the window's surface area, you use the formula for area of a circle.
A = 3.14*r^2
Plug in your number.
A = 3.14 * 2^2
Simplify.
A = 3.14 * 4
A = 12.56
Now, you subtract the area of the window from the total area of the wall.
92 - 12.56 = 79.44
79.44 feet
9514 1404 393
Answer:
(c) 2^r = a

I find this easier to remember if I think of a logarithm as being an exponent.
Here, the log is r, so that is the exponent of the base, 2.
This equivalence can also help you remember that the rules of logarithms are very similar to the rules of exponents.
