Are we solving for h?
V=πr²h+r²h
V=h(πr²+r²)
V/(πr²+r²) = h

*****For this problem, I substituted pi, with x, because I cannot find the pi button :/ sorry if it gets confusing... :(

V = xr²h + r²h //solve for h

Factor out the h

V = (xr² + r²) h

divide by xr²+r²

V / xr² + r² = h

Hope this helped! :D

Answer:

  see attached

Step-by-step explanation:

The scaling shown in the attachment is about as close as I can get using an on-line graphing program. You may fare better with graph paper. The vertex and x-intercepts are shown. The values at x=-3 and x=2 are y=11.

Prove the identity secxcscx(tanx+cotx)=2+tan^2x+cot^2x
svetlana [45]
Hello,

sec(x)= \dfrac{1}{cos(x)} \\&#10;&#10;cosec(x)= \dfrac{1}{sin(x)} \\&#10;&#10;sec(x)*cosec(x)*(tg(x)+cotg(x))=\dfrac{1}{cos(x)}* \dfrac{1}{sin(x)}*( \frac{sin(x)}{cos(x)} +\frac{cos(x)}{sin(x)})\\&#10;&#10;= \dfrac{sin^2(x)+cos^2(x)}{sin^2x*cos^2x} \\&#10;&#10;= \dfrac{1}{sin^2x*cos^2x} \\&#10;&#10;
==============================================================
2+tg^2(x)+cotg^2(x)=2+ \dfrac{sin^2x}{cos^2x} + \dfrac{cos^2x}{sin^2x} \\&#10;&#10;=2+ \dfrac{sin^4x+cos^4x}{sin^2x*cos^2x} \\&#10;&#10;=\dfrac{2*sin^2x*cos^2x+sin^4x+cos^4x}{sin^2x*cos^2x} \\&#10;&#10;= \dfrac{(sin^2x+cos^2x)^2}{sin^2x*cos^2x}} \\&#10;&#10;= \dfrac{1}{sin^2x*cos^2x}} &#10;
