So here are a few rules with exponents that you should know:
- Multiplying exponents of the same base:
- Dividing exponents of the same base:
- Powering a power to a power:
- Converting a negative exponent to a positive one:
<h2>1.</h2>
Firstly, solve the outside exponent:
Next, convert the negative exponents into positive ones:
<u>Your final answer is 
</u>
<h2>2.</h2>
For this, just divide:
<u>Your final answer is 
</u>
<h2>3.</h2>
For this, convert all negative exponents into positive ones:
<u>Your final answer is 
</u>
the equation of the line is y= x-4
Step-by-step explanation:
so so the first thing that you're going to do is get y alone
-x-5=y
next you're going to find your slope which in this case is negative one.
after that in order to find the equation of a parallel line you're going to find the reciprocal of the slope.
so in this case the reciprocal is one.
next you're going to substitute in the cordinates to find the y intercept
x+b=y. (-1)+b= -5. (. b is the y intercept)
b= -4
Yep! They are all right! Great job, could write a bit better.... sorry
The answer is 3+-i
I hope this helps!!!!!!!!
Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
Thus, the correct option is, Exponential Decay, $23,914.85.
