Answer:
c=
ad+b
a
give me brilliant please
Step-by-step explanation:
a=
b
c−d
Step 1: Multiply both sides by c-d.
ac−ad=b
Step 2: Add ad to both sides.
ac−ad+ad=b+ad
ac=ad+b
Step 3: Divide both sides by a.
ac
a
=
ad+b
a
c=
ad+b
a
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
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
The answer should be 0.875.
Hmm, it looks like it could be commutative property of multiplication.
The order of the expression is different.
4(2+3)=
4(5)=20
(2+3)4=
(5)4= 20
Yeah there all right but I have a little hinch for the last and first one
