For any direct variation: x=ky so k=x/y
k=4.8/2=2.4
k=10.8/4.5=2.4
k=14.4/6=2.4
Since k is a constant, you get the same value when you use any set of x and y values from the table. I just wanted to show you that.
The constant of variation(k)=2.4
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Hope this helps!
The correct answer for the question that is being presented above is this one: "a. prevention of accidents." Safety training in the workplace should be focused on a. prevention of accidents. Prevention is better than cure. As early as possible, any untoward incidents must be prevented.
Hello!
Reflecting across the y-axis will invert our x-value in our original point. This gives us the point (-3.4)
I hope this helps!
Hello,
Write an expression to describe a rule for the sequence. Then find the 100th term in the sequence. 4,9,14,19,24,29...
Rule: +5
This question was relatively simple because all you had to do was divide the total in the answer choices by 100 and to see if you would get by 5
Since it starts at 4 and that dosen't evenly match with 100 the answer is A. 4+5n;504
