Here is the equation:

Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
Divide both sides by -3.9 to leave the variable alone:

r is equal to 4 → r = 4
2/5 | 52% | 0.57 is the answer
100pi/10pi this is irrational but reduces to 10, a rational number
For this case we have an exponential expression of the form:

We can rewrite the exponential expression using power properties.
We have then:

From here, we take the square root of 36.
We have then:
Answer:
The exponential function is given by:
Answer: 5
Step-by-step explanation: 30 divided 6 is five
