Hello,

tan (t)<0
==> sin (t) /cos (t)<0
==>1 / cos (t)<0  [since sin (t) ≠0, dividing  by sin (t) ]
==> cos (t) <0

anzhelika [568]

Answer:

189 people

Step-by-step explanation:

We can make a proportion to solve

We know that 7 out of 8 people prefer Brand X, and p out of 216 people prefer Brand X, so

7/8=p/216

To solve, we need to get p by itself.

To do this, we must multiply both sides by 216 to "reverse" the division being done to p.

216(7/8)=(p/216)216

189=p

So, out of 216 people, 189 people will prefer Brand X.

Find the interval(s) of upward concavity on this accumulation function.
maxonik [38]

\displaystylef(x)=\int_{0}^{x^2}\sec^2(\sqrt{x})dx \\=\int_{0}^{\sqrt{x^2}}\sec^2(u)\cdot2udu \\=2\int_{0}^{\sqrt{x^2}}\sec^2(u)du \\=2\Big[u\tan(u)-\int\tan(u)du\Big]_{0}^{\sqrt{x^2}} \\=2\Big[u\tan(u)+\ln\Big(\mathrm{abs}(\cos(u))\Big)\Big]_0^x \\=2\Big(x\tan(x)+\dfrac{1}{2}\ln\Big(\cos^2(x)\Big)\Big) \\=2x\tan(x)+\ln(\cos^2(x))

Hope this helps.
