eimsori [14]4 years ago
7 0
7k + 2m = kr + 4m + 3
7k - kr = 4m - 2m + 3
7k - kr = 2m + 3
k(7 - r) = 2m + 3
k = (2m + 3) / (7 - r)

Write a power function representing the verbal statement. (Let k represent the constant of proportionality)
Tatiana [17]

The Power function representing the verbal statement is W = k.n^{1/2}.

<h3>What is the Power function?</h3>

A power function is in the form of f(x) = kxⁿ, where k = all real numbers and n = all real numbers. You can change the way the graph of a power function looks by changing the values of k and n.

When two quantities are proportional, their relationship can be described by the linear equation y = kx, where k is the constant of proportionality.

Now "inversely proportional to the square root" is the same as "proportional to the inverse of the square root."

According to question,

       W α 1/√n

      W = k/√n

      W = k.n^{-1/2}

Thus, the Power function representing the verbal statement is W = k

madreJ [45]

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "x3"   was replaced by   "x^3".  2 more similar replacement(s).

((3•(x2))+(9•(x2)))-3x3

((3 • (x2)) +  32x2) -  3x3

(3x2 +  32x2) -  3x3

Pull out like factors :

12x2 - 3x3  =   -3x2 • (x - 4)

-3x^2 • (x - 4)
