Answer:
See below.
Step-by-step explanation:
1)
So we have the limit:
This is equivalent to:
To solve, we can use the following property:
Therefore, our limit is the same as:
We are already given that the limit as x approaches 4 of g(x) is -2. Therefore:
You simply need to evaluate this to solve the limit. I don't have enough information to solve this, so maybe you have something more.
Similarly, for the second one:
2)
We have:
Using the same property:
And we are told that this is 16, so:
And we just need to evaluate this to find the limit.
I hope you find this helpful!
Answer:
304
Step by step:
Using your calculator 5% of 320 is 16.
Since it was a discount, you subtract 16 since you're marking it down.
320-16=304
304 is your answer
How do I know? Well, there it takes 20+20+20+20+20 to equal a hundred. We can do this same math for this problem. 16 x 20 is 320
This is a quadratic equation. There's a shortcut (two shortcuts really) called the Shakespeare Quadratic Formula (2b or -2b) applicable when the middle term is even:
OK, our problem is
Typically we'd write but the answers here don't so we won't either.
