Answer: 4
Step-by-step explanation: Because 4x5=20 and 20x4=80 than 80x4=320
For this case we must resolve the following expression:![log_ {0.5} (16)](https://tex.z-dn.net/?f=log_%20%7B0.5%7D%20%2816%29)
We have to:
![log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}](https://tex.z-dn.net/?f=log_%20%7Ba%7D%20%28x%29%20%3D%20%5Cfrac%20%7Blog_%20%7Bb%7D%20%28x%29%7D%20%7Blog_%20%7Bb%7D%20%28a%29%7D)
The base change rule can be used if a and b are greater than 1 and are not equal to x.
We substitute the values in the base change formula, using ![b = 10](https://tex.z-dn.net/?f=b%20%3D%2010)
![\frac {log (16)} {log (0.5)} = - 4](https://tex.z-dn.net/?f=%5Cfrac%20%7Blog%20%2816%29%7D%20%7Blog%20%280.5%29%7D%20%3D%20-%204)
Answer:
-4
Option A
I think it would be 186. hope it helps
The center is the point of reference for the dilation (like the vanishing point in a perspective drawing) and scale factor tells us how much the figure stretches or shrinks. A scale factor is typically labeled \begin{align*}k\end{align*} and is always greater than zero..
