Below is a plot of the graph of this equation. It repeats in all directions, as you would expect from periodic functions. So aren't there an infinite number of solutions for which it is true?

The generic solution is n·π +/- 1/6π, for all n.

3. What is the scale factor of Figure B to Figure A?

xxMikexx [17]

Answer:

2.5

Step-by-step explanation:

From the diagram, figure B was enlarged to obtain figure A.

The two figures are therefore similar.

The corresponding sides are in the same proportion. That constant value of the proportion is called scale factor.

It is given by:

$k = \frac{image \: length}{corresponding\:object \: length}$

Figure B is the image of A

$k = \frac{10}{4} = \frac{25}{10} = \frac{21.5}{8.6} = 2.5$

Therefore the scale factor is 2.5

Answer:

a = c - 3b/2

Step-by-step explanation:

2a + 3b - 3b = c - 3b

2a = c - 3b

2a/2 = c/2 - 3b/2

therefore your answer is a = c - 3b/2
