Solution:
Given that, 6 identical toys weigh 1.8 kg
we know that, 1kilogram = 1000 grams
6 identical toys weigh in grams
6 identical toys weigh 1800 grams
then calculating the weight of 1 toy by unitary method ,
weight of 1 toy =
grams.
Hence, 1 toy would weigh 300 grams.
Because she has more COLORED shirts then WHITE shirts it is likely she will pick a COLORED shirt.
11 +9 = 20 total shirts
probability for a colored one = 11/20
By converting into parametric equations,
<span><span>x(θ)=r(θ)cosθ=cos2θ<span>cosθ
</span></span><span>y(θ)=r(θ)sinθ=cos2θsinθ</span></span>
By Product Rule,
<span>x'(θ)=−sin2θcosθ−cos2θsinθ</span>
<span>x'<span>(π/2)</span>=−<span>sin(π)</span><span>cos<span>(π/2)</span></span>−<span>cos(π)</span><span>sin<span>(π/2)</span></span>=1</span>
<span>y'(θ)=−sin2θsinθ+cos2θcosθ</span>
<span>y'<span>(π/2)</span>=−<span>sin(π)</span><span>sin<span>(π/2)</span></span>+<span>cos(π)</span><span>cos<span>(π/2)</span></span>=0</span>
So, the slope m of the curve can be found by
<span>m=<span>dy/dx</span><span>∣<span>θ=<span>π2
</span></span></span>= <span><span>y'<span>(π/2)/</span></span><span>x'<span>(π/2)
</span></span></span></span>=0/1
=0
