Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = -5 - 5 cos θ
Grace [21]
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry

What is the value of x?<br><br> Enter your answer, as a decimal, in the box.
iragen [17]

Answer:

x = 67.50 ft

Step-by-step explanation:

Consider, ΔMAB and ΔMNP,

∠M = ∠M (Common)

Given AB║NP and let MN as transversal,

∠MAB = ∠MNP (alternate angle)

Also, Given AB║NP and let MP as transversal,

∠MBA = ∠MPN (alternate angle)

Therefore, ΔMAB ≅ ΔMNP (By AAA similarity )

Thus, by CPCT,

\frac{MA}{MN}=\frac{MB}{MP}=\frac{AB}{NP}

consider first two ratios,

\frac{MA}{MN}=\frac{MB}{MP}

Substitute the values, MA = MN - AN = 49.5 ft

\frac{49.5}{71.5}=\frac{x}{97.5}

On solving for x , we get, x = 67.50 ft

Thus, value of x is 67.50 ft
