It is determined by the kinds of atoms in the substance and their arrangement.<span />
Answer:
Step-by-step explanation:
From the law of variation,
y <> 1/x, where <> is the constant of proportionality. Therefore
y = k/x where k is a constant
3 = k/5 and k = 15
To find x when y = 2.5(5/2)
Go back to the second equation
y = k/x
5/2 = 15/x
When you cross multiply
5x = 30.
Divide through by 5,
x = 6.
Your answer would be C and D, the domain for this function is all real numbers, and the range for this function is the set {-5}.
C is correct: The domain of a function is the amount of x values. For example, if you had a line going from an x value of 1 to an x value of 3, the domain would be {1<x<3}.
In this case, C is stating the domain of this function is all real numbers. This is true, because the straight line will continue for all values of x, so therefore the domain is all values of x, or all real numbers.
D is correct: The range is the exact opposite of a domain of a function. It is the number of y values the function covers.
In this case, D is stating the range is {-5}. This is correct, because the straight line only covers the y value of -5, so therefore that is the range.
A is therefore incorrect because the domain has already been established as all real numbers. B is incorrect because a horizontal line is a function, and one value of y can have multiple values of x. E is incorrect because the range has already been established as only one number.
Good luck!
Simply plug it into the equation
y=mx+b or -4=-5/6(8)+b
Now just tie up loose ends and your equation will be
y=-5/6x+8/3
Answer:
18.8
Step-by-step explanation:
Hey there!
In order to find the solution to this question, we need to find the circumference
To find the circumference, you need to take the diameter and multiply it by 3.14 which is pi
In this case, the diameter is 6
6 x 3.14 is 18.84 so this means that the circumference of the circle, or in this case, a cookie, is 18.84
Also, it says to round to the tenth so our final answer will be 18.8
So the answer to this question is 18.8
