Answer:
Domain : all real numbers
Range: All numbers greater than 2
Step-by-step explanation:
The shark. (Haha, I'm sorry.)
There are no restrictions on the x. X can be any real number.
The range, however, does have restrictions. The range has to be a number greater than 0.
Why?
Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.
Answer + explanation:
1. Writing the function
You know that for every mile it costs 40 cents, or 0.4 dollars, so you can write this as 0.4m.
You also know that there is an initial fare of 2.5, so you add that.
Then you have F = 0.4m + 2.5
2. Find the better choice
Since she has to travel 5 miles, you can plug m = 5 into the function to see the cost:
F = 0.4 * 5 + 2.5
F = 2 + 2.5
F = 4.5 or $4.50
Since $4.50 < $8.00, you know that the cab would be the cheaper and better option.
Answer:
432 mm³
Step-by-step explanation:
Volume of a Rectangular Prism: V = lwh
Step 1: Define variables
<em>l</em> = 8
<em>w</em> = 6
<em>h</em> = 9
Step 2: Plug into formula
V = 8(6)(9)
Step 3: Evaluate
V = 48(9)
V = 432
And we have our answer!
