Evaluate \dfrac{3}{2}+(-k)+(-2)
Dimas [21]

As I understand, we need to evaluate the given rational expression, we will get that the evaluated expression is equal to - 1/10

<h3>Evaluating expressions:</h3>

Evaluating an expression just means that we need to replace the variable in the expression for a given value, here we have the expression:

\frac{3}{2} + (-k) + (-2)

And we want to evaluate it in:

k = -\frac{2}{5}

So we just need to replace k by that value in the above expression, we will get:

\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)

Now we can just solve this:

\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)\\\\\frac{3}{2} + \frac{2}{5}  + (-2)\\\\\frac{15}{10} + \frac{4}{10}  + (-2) = \frac{19}{10} - \frac{20}{10}= -\frac{1}{10}

ANSWER THIS!!!!!!!!!!
cluponka [151]

Answer:

r = sqrt( 3V/( pih))

Step-by-step explanation:

V = 1/3 pi  r^2 h

Solving for r

Multiply each side by 3

3V =  pi r^2h

Divide each side by  pi h

3V/( pi h)  = r^2

Take the square root of each side

sqrt( 3V/ (pi h) )= sqrt( r^2)

sqrt( 3V/ (pi h)) = r
