Define root squar

Answer» How simple<br>Square root of a number is a value, which on multiplied by itself gives the original number. Suppose, x is the square root of y, then it is represented as x=√y or we can express the same equation as x2\xa0= y. Here, ’√’ is the radical symbol used to represent the root of numbers. The positive number, when multiplied by itself, represents the\xa0square of the number. The square root of the square of a positive number gives the original number.

Slope intercept form?

Answer» The slope intercept form is in the form of y = mx + c in this m is the slope and c is the intercept on the x-axis.<br>The graph of the linear equation\xa0y\xa0=\xa0mx\xa0+ c is a line with m as slope,\xa0m\xa0and c as y-intercept. This form of the linear equation is called\xa0slope-intercept form. The values of m and c are real numbers.The\xa0slope,\xa0m, represents the steepness of a line. The slope of the line is also termed as gradient, sometimes. The y-intercept, b, of a line, represents the y-coordinate of the point where the graph of the line intersects the y-axis.

What is the formula for sum of n terms of G.P

Answer» Sn=a[r^n-1]/r-1<br>Let ‘a’ be the first term and ’r’(≠) be the common ratio of the given G.P.The general teams of G.P. If Sn\xa0denotes the sum of ‘n’ terms, then,Sn\xa0= a((1 - rn)/(1 - r)) r\xa0≠\xa01This can also written asSn\xa0= a((rn\xa0- 1)/(r - 1))Note: (1) Sn\xa0= a + ar + ar2\xa0+….. +arn-1\xa0(2) If r = 1, then Sn\xa0= a + a + a +……………+a – na\xa0(3) If r = 1, then formulas for Sn\xa0fail\xa0(4) If r < 1, then use Sn\xa0= a((1 - rn)/(1 - r))(5) If r > 1, use Sn\xa0= a((rn\xa0- 1)/(r - 1))(6) Sum of an infinite G.P.,a + ar + ar2 + ..... is a/(1 - r), - 1 r < 1(7) If a, b, c are in G.P.then ‘b’ is the G.M. (geometric mean) between a and c, then b2 = ac\xa0⇒ b =\xa0√ac(8) If A and G are A.M. and G.M. of two given distinct positive real numbers, then relation between A and G is A > G.

What is fibonacci sequence. With example??

Answer» Thnks yogita jii but itta lamba??<br>The\xa0Fibonacci sequence,\xa0also known as\xa0Fibonacci numbers, is defined as the sequence of numbers in which each number in the sequence is equal to the sum of two numbers before it. The Fibonacci Sequence is given as:Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, ….Here, the third term “1” is obtained by adding first and second term. (i.e., 0+1 = 1)Similarly,“2” is obtained by adding the second and third term (1+1 = 2)“3” is obtained by adding the third and fourth term (1+2) and so on.For example, the next term after 21 can be found by adding 13 and 21. Therefore, the next term in the sequence is 34.

Value of iota

Answer» The square root of a negative real number is called an imaginary quantity or imaginary number. e.g., √-3, √-7/2The quantity √-1\xa0is an imaginary number, denoted by ‘i’, called iota.Integral Powers of Iota (i)i=√-1, i2\xa0= -1, i3\xa0= -i, i4=1So, i4n+1= i, i4n+2\xa0= -1, i4n+3\xa0= -i, i4n+4\xa0= i4n\xa0= 1In other words,in\xa0= (-1)n/2, if n is an even integerin\xa0= (-1)(n-1)/2.i, if is an odd integer
