The sum of the first k terms in the sequence is 118096, find the value of k. The first term is 78732 the common ratio is 1/3.
FrozenT [24]

Answer:

k = 10

Step-by-step explanation:

The sum of k terms of a geometric sequence with first term a1 and common ratio r is given by ...

... Sk = a1·(1 -r^k)/(1 -r)

For the given numbers, this is ...

... 118096 = 78732·(1 -(1/3)^k)/(1 -1/3)

Manipulating this to get the term containing k, we have

... 1 -(2/3)(118096/78732) = (1/3)^k

... 1/59049 = (1/3)^k

Taking logarithms, we get

... -log(59049) = -k·log(3)

... log(59049)/log(3) = k = 10

Solve for x.<br> −7≥13−5x
Sergio039 [100]

Answer:

\[=>x\geq 4\]

Step-by-step explanation:

Given inequality is \[−7\geq13−5x\]

Simplifying:

\[5x\geq13+7\]

\[=>5x\geq20\]

\[=>x\geq \frac{20}{5}\]

\[=>x\geq 4\]

Hence the solution for the given inequality is represented by  \[=>x\geq 4\]

This means that the original inequality will be true only for those values of x which are greater than or equal to 4.

An augmented matrix for a system of linear equations in x, y, and z is given. Find the solution of the system.
Angelina_Jolie [31]

Answer:

  (x, y, z) = (-4, 2, 1)

Step-by-step explanation:

See the attachment for the output of a calculator that produces the reduced row-echelon form of the matrix.

The [x, y, z] result vector is the column on the right.

  (x, y, z) = (-4, 2, 1)

_____

Numerous web sites are available for computing the row-reduced form of the matrix, or for solving the system of equations. Your graphing calculator will do it as well.

Please solve this question asap
disa [49]

Step-by-step explanation:

y =  \sqrt{4x + 6}

{y}^{2}  = 4x + 6

{y}^{2}  - 6 = 4x

\frac{1}{4} ( {y}^{2}  - 6) = x

Swap x and y

\frac{ {x}^{2} - 6 }{4}  = y
