$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ K(\stackrel{x_1}{-7}~,~\stackrel{y_1}{5})\qquad H(\stackrel{x_2}{5}~,~\stackrel{y_2}{7})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ KH=\sqrt{[5-(-7)]^2+[7-5]^2}\implies KH=\sqrt{(5+7)^2+(7-2)^2} \\\\\\ KH=\sqrt{144+4}\implies KH=\sqrt{148}\implies KH\approx 12.17$

1/4k = 3 (-1/4k + 3)

Arada [10]

Answer:

For the expression $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

k = 9 is the required solution.

Step-by-step explanation:

Here, the given expression is $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

Solving the above expression for k, we get:

$\frac{1}{4} k = 3 (-\frac{1}{4}k +3) \implies \frac{k}{4} = (\frac{-3}{4}k) + 9$

or, $\frac{k}{4} + (\frac{3}{4}k) = 9 \implies \frac{k + 3k}{4} = 9$

or, $\frac{4k}{4} = 9 \implies k =9$

or, k = 9

Hence for the expression $\frac{1}{4} k = 3 (-\frac{1}{4}k +3)$

k = 9 is the required solution.

Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have alre

azamat

Answer:

total = 0;

for (k = 0; k <= n; k++)

total += Math.pow(k,3);

Step-by-step explanation:

Here the variable total is declared and initialized with a value zero

Then a for loop is defined with a counter k whose initial value is set to zero then a condition for the loop is that the counter k does not exceed n k<=n and then within the loop a statement which add the cube of the counter k to the variable total and still assigns it to the variable total is defined

total += Math.pow(k,3);

What this program does is to obtain the sum of the cubes of k
