11:30 am. 8:35 + 2 hours = 10:35 + 5 mins = 10:40 + 50 mins = 11:30 am
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

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
Answer:
30
Step-by-step explanation:
because if x is 5 then 6(5)
and 6x5=30
Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.
<h3>What is a
circle? </h3>
A circle is the locus of a point, such that the distance from a fixed point (center) is always constant.
The circumference of a circle is given by:
Circumference = π * diameter
Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.
