Answer:
Profit=Rs90
Step-by-step explanation:We know that,Profit=Sp-Cp =Rs 810-Rs720 =Rs 90
It looks like you want to compute the double integral
over the region <em>D</em> with the unit circle <em>x</em> ² + <em>y</em> ² = 1 as its boundary.
Convert to polar coordinates, in which <em>D</em> is given by the set
<em>D</em> = {(<em>r</em>, <em>θ</em>) : 0 ≤ <em>r</em> ≤ 1 and 0 ≤ <em>θ</em> ≤ 2<em>π</em>}
and
<em>x</em> = <em>r</em> cos(<em>θ</em>)
<em>y</em> = <em>r</em> sin(<em>θ</em>)
d<em>x</em> d<em>y</em> = <em>r</em> d<em>r</em> d<em>θ</em>
Then the integral is
Answer:
2.52
Step-by-step explanation:
4.2% of 60 = 4.2% * 60
4.2% = 0.042
0.042 * 60
2.52
Step-by-step explanation:
It is 64*0.32=20.48 minutes or 20.5 minutes.
