Answer:
9 or -17
Step-by-step explanation:
Hello!
The distance can be positive or negative, as we are just counting the number of units they are apart.
To find the possible coordinates for G, we can add or subtract 13 from -4 to find the possible coordinates for G.
<h3>Find G</h3>
- -4 + 13 = G1
-4 - 13 = G2
- 9 = G1
-17 = G2
The possible coordinates of G are 9 or -17.
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.
At th x-intercept y=o
∴40x + 70 = 0
40x = -70
x = -70/40
x = -1.75
x intercepr = (-1.75,0)
answer is either A or D
I hope this help. but I'm not really sure.
