The sum of the first 3 terms of a geometric series is 171 and the common ratio is 2/3
S_A_V [24]

Answer:

81

Step-by-step explanation:

The formula for calculating the sum of geometric series varies depending on the value of its common ratio.

Given the common ratio to be 2/3 which is less than 1, the formula to be used is given as;

Sn = a(1-rⁿ)/1-r

n is the number of terms of the series

a is the first term

r is the common ratio.

Sn is the sum of the series

Given n = 3, r = 2/3 and Sn = 171,

a= ?

Substituting this values in the formula we have;

171 = a{1-(2/3)³}/1-2/3

171 = a{1-8/27}/(1/3)

171 = a(19/27)/(1/3)

171 = 19a/27 × 3/1

171 = 57a/27

57a = 171×27

57a = 4,617

a = 4,617/57

a = 81

The first term of the series is 81

Help math hw pls Fractional indicies
solmaris [256]

Answer:

C

Step-by-step explanation:

1. If it is to the power of a negative, you do the reciprocal, so you know the answer will be 1/y.

2. If it is to the power of 4/3, you know it is \sqrt[3]{y} ^{4\\} (y cubed to the power of 4), so the whole answer is 1/\sqrt[3]{y} ^{4\\}

Which of the following equations graphs as a vertical parallel to the y-axis?
neonofarm [45]

Answer:

x = 1 is the equation of a vertical line parallel to y-axis, as shown in attached figure.

Step-by-step explanation:

  • As the equation of y-axis is x=0.
  • If a line is parallel to y-axis i.e. x=0, then location of the that line will have at some distance - let say d - from y.
  • The Distance d will be positive or negative depending on whether the line is located at the left side or right side of the y-axis.
  • So, the equation of any parallel line to the y-axis and has an x-intercept will have an equation like x = a where a is the x-intercept.
  • The slope of this vertical line will be undefined.

Therefore, from the above discussion, we can safely say that x = 1 is the equation of a vertical line parallel to y-axis, as shown in attached figure.
