43/8 7/8+4 1/2 Here, 4 1/2 is nothing other than 4+1/2. The calculation goes this..... 7/8+4 1/2 =7/8+(4+1/2) =7/8+(4(2)+1)/2 =7/8+(8+1)/2 =7/8+9/2 =7/8+(9(4))/(2(4 ...
How do you find the midpoint of the line segment joining (4
May 17, 2018 · For a line segment AB, one endpoint is A(0,6) and the midpoint is M(4,7) how do you find the
How do you use sigma notation to write the sum for
Jun 19, 2017 · How do you use sigma notation to write the sum for #1/2+2/4+6/8+24/16+120/32+720/64#?
How do you find the sum of the terms of geometric 1, -2, 4, -8 ...
-5461 The general term of a geometric sequence is given by the formula: a_n = a * r^(n-1) where a is the initial term and r the common ratio. In our example a = 1 and r = -2 If we want to sum the first N terms, we find: (r - 1) sum_(n=1)^N a_n =(r - 1) sum_(n=1)^N a r^(n-1) =r sum_(n=1)^N a r^(n-1) - sum_(n=1)^N a r^(n-1) =sum_(n=2)^(N+1) a r^(n-1) - sum_(n=1)^N a r^(n-1) =a r^N + …
How do you use sigma notation to write the sum for
Feb 19, 2017 · 1/4+3/8+7/16+15/32+31/64 = sum_(r=1)^5 (2^n-1)/2^(n+1) If we look at the sequence for the terms in denominator we have: {4,8,16,32,64} It should be obvious that these numbers are successive powers of 2, with the first term 2 missing so the general term of the above sequence would be: u_n=2^(n+1) where n in {1,2,3,4,5} And now we look at the …
How do you use the geometric sequence of numbers 1, 2, 4, 8
a_24=2^23=8388608 This sequence has a_1=1 q=2 To calculate the n-th term you use the formula a_n=a_1*q^(n-1)
How do you calculate number of valence electrons in an neon?
Nov 23, 2017 · Neon is noble. The periodic table is your friend. Where can neon (Ne ) be found? Do you see it? If not, look for Group VIIIA. If you don't understand Roman numerals, that is '8'. Elements in Group 8 have one thing in common: their valence shells are full, i.e. they satisfy the octet rule. Octet, you ask? Let me ask you something... How many tentacles does an Octopus …
How do you find the greatest common factor of 20, 16?
16 factors are: 1, 2, 4, 8 and 16. 20 factors are 1, 2, 4, 5, 10 and 20. Numbers that are factors of 16 and 20: 1, 2, 4. The greatest of these is 4. There are a more useful method to calculate GCF of a set of numbers: Factorize all numbers in the set; Take a factor of each base that is repeated with exponent equals to the lowest of they.
What are all the possible rational zeros for - Socratic
Nov 14, 2016 · The "possible" rational zeros are: +-1, +-2, +-4, +-8 The actual zeros are: -1, 4, +-sqrt(2) f(x) = x^4-3x^3-6x^2+6x+8 By the rational root theorem, any rational zeros of f(x) are expressible in the form p/q for integers p, q with p a divisor of the constant term 8 and q a divisor of the coefficient 1 of the leading term. That means that the only possible rational zeros are: + …
How do you find the set in which the real number - Socratic
Mar 9, 2017 · -sqrt(0.0625) is a rational number. Note that: 0.0625 = 0.125/2 = 0.25/4 = 0.5/8 = 1/16 = (1/4)^2 So: sqrt(0.0625) = sqrt((1/4)^2) = 1/4 So: -sqrt(0.0625) = -1/4 This is a rational number, since it is expressible in the form p/q for integers p, q …
