Answer:
3.1 ≤d≤183.1
Step-by-step explanation:
d = 4.5t + 3.1
Since this is a line, we can find the range by putting in the minimum and maximum of the domain
domain = 0≤t≤40
Let t =0
d = 0+3.1 so the minimum of the range is 3.1
Let t = 40
d = 4.5(40)+3.1
d = 183.1 so the maximum is 183.1
The range is 3.1 ≤d≤183.1
Answer:
-14 - 11i
Step-by-step explanation:
You may be learning about the imaginary number, i. Even though i is actually the squareroot of -1, when you are doing algebra with it, it acts just like a variable does. The special thing to remember about i is that i^2 is -1. But we don't even need that right now for this problem.
(-14 + 3i) - (14i)
= -14 + 3i - 14i
Combine the i's
= -14 - 11i
That's it. The -14 is the a, and the -11 is the b in a+bi.
If necessary to fill in a computer answer that is already formatted with a plus, like:
_ + _i
then use -14 for a and -11 for b.
My hand writing is messy but you would take. 40$ × 0.10 . then you would take 40$ and subtract it from the answer you received from multiplying and then you have your answer.
The odds in favor of winning $5 or more is 3 : 13
<h3>What are the odds in favor of winning $5 or more?</h3>
The odds of winning $5 or more can be determined by finding the ratio of the total value of tickets that have a value of $5 or greater to the total value of tickets.
Total number of the tickets that have a value of $5 or more = 25 + 5 = 30
Total number of ticket = 25 + 5 + 100 = 130
Ratio : 30 : 130
3 ; 13
