The value of double integration can be found by applying limits and integrating them one by one.

<h3>What is integration?</h3>

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

We have:

\rm \int\limits \int\limits_R {ye^{-xy}} \, dA \ , R = [0,2]\times[0,3]

After plugging limits:

\rm \int\limits^3_0 \int\limits^2_0 {ye^{-xy}} \, dx dy\

After solving the first integration:

\rm \int\limits^3_0  {(-e^{-2y}+1)} \, dy\

After solving the further integration and plugging limits:

=\rm \dfrac{e^{-6}(5e^{6}+1)}{2}

\rm \int\limits \int\limits_R {ye^{-xy}} \, dA \ =\dfrac{e^{-6}(5e^{6}+1)}{2}

Thus, the value of double integration can be found by applying limits and integrating them one by one.

Find the measure of angle of hmg<br><br>PLS HELP AND SHOW WORK​
Anna11 [10]

Answer:

70 degrees

Step-by-step explanation:

Angle HMK = 50 degrees

Angles LMK, MLK and MKL are equal to 60 degrees, being in a perfectly congruent triangle which they all add up to 180 degrees.

Add 60 to 50 = 110

180 - 110 = 70 degrees, equal to angle HMG.

This is because the line that angles LMK, HMK and HMG are on is supplementary.
