Two figures are similar if one can be mapped onto the other by rigid rotation, reflection, and translation. Two figures are similar if one can be mapped onto the other by rotation, reflection, translation, or dilation/rescaling.

a cubic block of wood is painted various colours on all sides, each side of the block has the same leng of 12 cm. thos block is

MakcuM [25]

Number of cubes length-wise = 12 ÷ 3 = 4
Number of cubes width-wise = 12 ÷ 3 = 4
Number of cubes height-wise = 12 ÷ 3 = 4

Total number of cubes = 4 x 4 x 4 = 64

--------------------------------------------------------------------------------------
Answer: 64 cubes were created from the original block.

Consider the following geometric sequence: -5, 10, -20, 40,..... if the explicit formula for the sequence above is expressed in

Dima020 [189]

To solve this we are going to use the formula for the nth term of a geometric sequence: $a_{n}=a_{1}r^{n-1}$
where
$a_{n}$ is the nth term
$a_{1}$ is the first term
$r$ is the common ratio
$n$ is the place of the term in the sequence

Notice that we can infer for our problem that $B=a_{1}$ and $C=r$ .

Now, to find our common ratio, we are going to use the formula $r= \frac{a_{n}}{a_{n-1} }$
where
$a_{n}$ is the current term in the sequence
$a_{n-1}$ is the previous term in the sequence
for $a_{n}=10$ and $a_{n-1}=-5$ :
$r= \frac{10}{-5}$
$r=-2$

Since $r=C$ , we can conclude that $C=-2$ .

Notice that the first therm of our geometric sequence is -5, so $a_{1}=-5$ . Since $B=a_{1}$ , we can conclude that $B=-5$ .

We can conclude that the values of B and C in our geometric sequence are: $B=-5$ and $C=-2$ .
