Answer:
12.5
Step-by-step explanation:
49.00/3.92=12.5
One of the rules of logarithms is as follows;

We can now insert the corresponding values in the question provided, as shown below;

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

Therefore, our equation can now be re-written as follows;

However, the question requires the answer to be expressed in exponential form. Therefore,
Answer:
Vertical stretch across the y-axis, reflection across the x-axis, horizontal shift 2 units to the left, and vertical shift 1 unit down
Answer:
The value of
is 
Step-by-step explanation:
Rearrange the terms so that all terms containing the variable are on one side of the equation and all constant terms are on the other side.
Subtract
from both the sides.
