Answer:

Pythagorean Theorum:

16ft

Step-by-step explanation:

pythagorean theorum states a^2+b^2=c^2

it only works for right triangles, c is the hypotenuse, a and b are the legs

so to find b we plug in the info we have!

7.8^2+b^2=17.8^2

next we simplify:

60.84+b^2= 316.84

subtract 60.84 from both sides to isolate the variable:

b^2=256

square root both sides

b=16

16ft is the answer

I hope this helps!

Use a surface integral to ﬁnd the surface area of the portion of the sphere xUse a surface integral to ﬁnd the surface area of t

brilliants [131]

Parameterize this surface (call it $S$ ) by

$\vec r(u,v)=\cos u\sin v\,\vec\imath+\sin u\sin v\,\vec\jmath+\cos v\,\vec k$

with $0\le u\le2\pi$ and $0\le v\le\dfrac\pi4$ . The limits on $u$ should be obvious. We find the upper limit for $v$ by solving for $v$ where the sphere and cone intersect:

$\begin{cases}x^2+y^2+z^2=1\\z=\sqrt{x^2+y^2}\end{cases}\implies x^2+y^2=\dfrac12$

$\implies(\cos u\sin v)^2+(\sin u\sin v)^2=\dfrac12$

$\implies\sin^2v=\dfrac12$

$\implies\sin v=\dfrac1{\sqrt2}\implies v=\dfrac\pi4$

Take the normal vector to $S$ to be

$\vec r_u\times\vec r_v=-\cos u\sin^2v\,\vec\imath-\sin u\sin^2v\,\vec\jmath-\cos v\sin v\,\vec k$

(orientation does not matter here)

Then the area of $S$ is

$\displaystyle\iint_S\mathrm dA=\iint_S\|\vec r_u\times\vec r_v\|\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{\pi/4}\int_0^{2\pi}\sin v\,\mathrm du\,\mathrm dv$

$=\displaystyle2\pi\int_0^{\pi/4}\sin v\,\mathrm dv=\boxed{(2-\sqrt2)\pi}$

Question 1

Andrews [41]

The club currently have 25 members

Yolanda's club requires that 80% of the members be present for any vote. If at least 20 members must be present to have a vote, it means that 80% of the members in Yolanda's club is 20 members.

In order to determine the number of members in the club, use this formula:

Number of members in the club = least number of members that have to be present to vote / percentage of members that must be present to vote

least number of members that have to be present to vote = 20

percentage of people that must be present to vote = 80%

20 / 0.8 = 25 members
