Answer:
D. All real numbers
Step-by-step explanation:
The range of a function is all of the possible x-values (which is easiest to understand if you can view a graph), and the domain of a function is all possible y-values.
So, you could put any x-value into this function (and it would have a corresponding y-value)
The domain [y] is limited, but the range [x] is best described as all real numbers
(if it's hard to remember which is which, d comes before r alphabetically, and x comes before y alphabetically)
Hello!
There is a discount of 40%, which means that we will be subtracting 40% of the price, and then sales tax is basically additional money added to the price, so we will be adding that.
65.00 * 40% = 26
65.00 - 26 = 39
So, the discounted price is $39. Now we must add tax on that.
39 * 5% = 1.95
39 + 1.95 = 40.95
The final price of the jacket is $40.95.
Answer:
yes
Step-by-step explanation:
this number is a decimal
Answer:
see below
Step-by-step explanation:
This graphs as 3 horizontal lines. The open circles are at the ends of the interval where the function is undefined or is defined as a different value.
The area of the trapezoid is calculated through the equation,
A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given,
A = 0.5(9.6 + 25)(90) = 1557 mi²
Therefore, the approximate area of the country is 1557 mi².
