Step-by-step explanation:
84% of 150=126 (foreign coins)
150-126=24 (non foreign coins)
Answer:
after 5 months, the petri dish will have 332 bacteria :)
Step-by-step explanation:
7% of 246 = 17.22
every moth, the bacteria increases by 17.22
17.22 x 5 = 86.10
246 + 86.10= 332.1
rounded to the nearest whole number= 332
Answer:
General solution
<em> θ =</em><em></em>
<em>Put n=1 </em>
<em> θ</em> = 210°
put n =2
<em> θ</em> = 330°
put n=3
<em> θ</em> = 270°
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given equation </em>
<em> sin 2θ cosθ + cos 2θ sinθ = -1 </em>
<em> we know that </em>
<em>Sin (A+B) = sin A cos B +Cos A sin B </em>
<em> sin( 2θ+θ) = sin (180+90)</em>
<em> = </em><em></em>
<em> sin 3θ = sin (3π/2)</em>
<em>General solution of sinθ = sinα </em>
<em> θ = 2 n π ±α</em>
<em> 3θ = 2 n π ±3π/2</em>
<em> θ =</em><em></em>
<em> θ =</em><em></em>
<em>Put n=1 </em>
<em> θ=</em> = 210°
put n =2
<em> θ=</em> = 330°
Put n=3
<em> θ=</em> = 270°
