Answer: I think it's 0.4

Step-by-step explanation:

Adding all the numbers together (0.2; 0.4; 0.4; 0.6) gives you 1.6 which, when divided by the amount of numbers, gives you 0.4. If that isn't the kind of mean you're referring to. It'd still be 0.4 because it is the value in the middle of all given numbers.

Answer:

-57

Step-by-step explanation:

$log \frac{ {c}^{7} }{ {a}^{6} {b}^{2} } \\ \\ = log {c}^{7} - log( {a}^{6} {b}^{2} ) \\ \\ = log {c}^{7} - (log {a}^{6} + log{b}^{2} )\\ \\ = 7 \: log {c} - (6 \: log {a}+ 2 \: log{b})\\ \\ = 7 \:( - 9) - [6 \: ( - 5)+ 2 \: (12)] \\ \\ = - 63 - [ - 30 + 24] \\ \\ = - 63 - [- 6] \\ \\ = - 63 + 6 \\ \\ = - 57$

what solid 3D object is produced by rotating the triangle about line m with a height of 8 and radius 4

Oksi-84 [34.3K]

Answer:

The diagram of the question is missing, I found a matching diagram, and it is attached to this answer

The 3D object produced is a cone with height 8 and diameter 8 (radius 4)

Step-by-step explanation:

A 3 dimensional solid figure can be formed when a 2 dimensional object is rotated about a line without displacing the object.

when the object in the diagram is rotated about line m, the rotation forms an object with a circular base of diameter 8 units (radius 4) from the base of the triangle and height 8 units, and the 3D object formed is called a cone.
