8. domain=hours
range=cost
it is a function because there is a y value for ever x
9. minutes =60, 120,180, 240 (domain)
calories= 360, 720, 1080, 1440 (range)
this is also a function
For this case, we can model the problem as a triangle with a right angle.
Where,
x, y: lengths of the sides of the triangle
d: hypotenuse of the triangle
We then have the following relationship:

Clearing d we have:
Answer:
A functions that would best model the situation above is:
D square root
Answer:
Step-by-step explanation:
Let x be the "number."
"twice the difference of a number and 16" can be written as:
2(x-16)
"is the same as three times a number less than 18" can be written as:
= 3(x<18)
I wonder if this was meant to say "is the same as three times a number less 18," instead of "less than 18." If so, we would have:
=3(x-18)
1. Using the sentence as written: 2(x-16) = 3(x<18)
2. Using the sentence as amended: 2(x-16) = =3(x-18)
Going with this interpretation:
2(x-16) = 3(x-18)
2x - 32 = 3x - 54
x = 22
n would equal <em>-33</em>.
<em>n=-33</em>
I will assume that this question is about scientific notation (also assuming that the first number is 3.4*10^2), where you can arrange the numbers by the exponent of the 10, so from least to greatest:
