12.2 geometric sequences evaluate homework and practice answers

Answers

Answer 1

Geometric Series is known to be the exact sum of the terms of a geometric sequence. Its practice work example is given below:

Find the stated term of Given of the Geometric sequence  -3, -6, -12, -24 ...9th term.

What is Geometric Means?

This is known to be the terms that exist  between two nonconsecutive terms that belongs to a geometric sequence.

The Method to used in the above question is Geometric sequence.

The Rule of geometric sequence is that f (n)arⁿ⁻¹

Where A  =  the first term,

r = the  common ratio

Therefore, r = -6 ÷ -3 = 2n

f (n) = -3. 2ⁿ⁻¹

Then you change the term n with 9

f (9) = 3.2⁹⁻¹

= -768

Therefore, the the stated term is 768.

The question is incomplete as the dimensions or the figure is not given

So, I will provide a general solution

Assume the shape is a cylinder, with the following parameters:

Radius, r = 5 cm

Height, h = 3 cm

The volume is:

V = π r² h

This gives

V = (3.14) (5 cm)² (3 cm)

The algebra shows that the line ax + y + c is perpendicular to the line x - by = d, then a/b = 1.

How to solve the algebra?

Firstly, write the equations of line in the slope intercept form. The equation ax + y = can be rewritten as y = ax + c. The slope of the line is m = a.

The equation x - by = d can be written as y = 1/bx - d/b. Therefore, the second slope will be 1/b.

Then, we multiply the slopes. Therefore, (-a)(1/b) = -1.

6-4 practice elimination using multiplication answers

Answers

Multiplication as a method of elimination is used to eliminate an unknown in a system of equations by multiplying one of the equations by a constant.

What is the Gauss method?

It is the method of eliminating unknowns that transforms a linear system into a triangular system, so that it is possible to solve the problem with retroactive resolution. Like for example:

2x+3y=143x-4y=4

A) The first step is to solve equation 2 to find the variable x.

3x=4y+4x=4y/3+4/3

B) The second step is to include the variable x found in equation 1.

2x(4y/3+4/3)+3y=14

17y/3=34/3

17y=34

C) The third step is to solve equation 1 to find the variable y.

17y=34y=2

D)Now that we've found the value of y, we can solve equation 1 to find the value of x.

x=4/3x(2)+4/3=4

Therefore, if the value of x is 4 and the value of y is 2, the solution of this exercise, using the Gauss method is (4;2).
