-13
Since a negative number (-2) divided by another negative number results in a positive number,
2
----------
13
Both Answers A and B are correct; the final value in each case is +2/13.
The equivalent expression will be (-2)/(-13) and-(-2/13) so option (A) and option (B) both will be correct.
What is numerator and denominator?In such a fraction, the value that appears above the horizontal line is referred to as the numerator. It represents the number of pieces removed from the whole.
The denominator of a fraction is the numerical value that comes before the brings together various.
If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator. For example a fraction 1/5 here 1 will be the numerator and 5 will be denominated.
Given that[tex]-\dfrac{2}{-13}[/tex] now since the multiplication of - and - quantity is always positive so - and - is positive so it will be 2/13
If you take both options A and B in both options the negative sign going to cancel and it will give a positive value.
Hence "The equivalent expression will be (-2)/(-13) and-(-2/13)".

Step-by-step explanation:
We need to use the formula :-
2 (l + b) × h ---> For Lateral surface area
2(30+30) h = 7200
2×60×h = 7200
120 × h = 7200
h = 7200/120
h = 60 cm
Now, volume = l×b×h
= 30×30×60
= 54000 cm³ is the required answer.
Hope it helps! :D
Answer:
54000cm³
Step-by-step explanation:
7200=4*30x，so x=60
In other words, the length of the vertical side is equal to 60cm
The volume inside the kite=60*30*30=54000cm³

Proof that the formula Fn = Fn-1 + Fn-2 works
Fibonacci python
Answers
IV. The sum of the first n Fibonacci numbers with even indices is
f2 + f4 + ... + f2n = f2n+1 - 1.
Proof:
From II,
f1 + f2 + f3 + ... + f2n = f2n+2 - 1.
When we subtract the result from III, we get the desired result.
Example:
f2 + f4 + f6 + f8 + f10 + f12 = 1 +3 + 8 + 21 +55 +144
= 232
= f13 - 1 .
V. The sum of all (fn+1)/ (fn )
converges to the Golden Ratio.
3/1 + 5/3 + 8/5 + 13/8 .... converges to ) / 2.
Proof that Rn converges to the Golden Ratio:
Let R = lim Rn as n approaches infinity
= lim f n+1 / f n as n approaches infinity
= lim fn + fn-1 /fn as n approaches infinity
= lim (1 + fn-1/ fn) as n approaches infinity
= 1 + lim (fn-1 /fn ) as n approaches infinity
= 1 + 1/ lim (fn-1 /fn ) as n approaches infinity
= 1 + 1/R
So, R = 1 + 1/R,
or R^2 = R + 1,
R^2 - R - 1 = 0,
R = ( ) / 2
= ( ) / 2
Since Rn is positive, Rn = ( ) / 2 .
Thus, Rn converges to the Golden Ratio.

find the first four terms and the tenth term
a) 3n^2
Answers
Step-by-step explanation:
3n^2
First term => n=1 => 3(1)^2 =>3
Second term => n=2 => 3(2)^2 =>3x4=12
Third term => n=3 => 3(3)^2 =>3x9=27
Fourth term => n=4 => 3(4)^2 =>3x16=48
Tenth term => n=10 => 3(1)^2 =>3x10=300
Answer:
{3, 12, 27, 48, 300}
Step-by-step explanation:
For the first four terms, n = {1, 2, 3, 4}. For the tenth, n = {10}.
Then, applying the formula a(n) = 3n^2 to n = {1, 2, 3, 4, 10}, we get:
{3(1)², 3(2)², 3(3)², 3(4)², 3(10)²} = {3, 12, 27, 48, 300}
