5 0

Answer:

12.566

Step-by-step explanation:

A = ∫1/2(r)^2dtheta from a - b = 0 to 2π

∫1/2(sin^2theta-4sintheta+4)dtheta

[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…

when you solve this you get 14.137 without taking out the cos(2theta+3)

Sliva [168]

Answer:

x = 0

Step-by-step explanation:

The axis of the symmetry has the same x coordinate of the vertex

Simplify<br><br> urgent pls​
Sonbull [250]

Answer: VI)

\frac{x - 1}{3(x+ 1)}

VII)

\frac{2(m - 7) \times (m + 7)}{n(n - 7)}

Step-by-step explanation:

VI)

\frac{{(x + 1)}^{2}}{6}  \times  \frac{2}{{x}^{2} - 1}

= \frac{2{(x - 1)}^{2} }{6(x - 1) \times (x + 1)}

=  \frac{x - 1}{3(x+ 1)}

VII)

\frac{{m}^{2}  - 49}{3n}  \div  \frac{2n - 14}{6}

=  \frac{(m - 7) \times (m + 7)}{3n}  \times  \frac{6}{2(n - 7)}

=  \frac{2(m - 7) \times (m + 7)}{n(n - 7)}

Can't type fast enough, LaTex is hard :(
