1st the spere is centered at z=4.5 and with radius 4.5 also
Right?

2nd the area is at the top of the sphere (inside the paraboloid)... but I can't find the limits of the area-- the projection of the area to the xy plane
that s for setting up the INT
look at James Stewart's book chap 15 & 16.

What I tried to do was subst. z=para- with z at sphere, but it was disastrous producing x^4 and y^4
right?

so I switch to spherical coordinate method of INT
here I tried to find the phi-Φ angle .. see stewart chapter 15..
and also the rho-ρ would change.. when we INT right ?

honestly I kinda suck at spherical coord there too..
I am still trying..

Actually I am quite pesimmistic that anyone here would be able to correctly solve it.. although the problem seem to be quite simple..
since for many times I have asked about problems from chap 15-16 stewart calculus..most of the time the ans were wrong..even thou they have really tried

So BIG thx and salute to the solver!!

Sam's wheel?
Sam's four wheel drive is capable of speeds of 40km/h across country and 80km/h along roads.he receives a call asking him to get home as quickly as possible.At the time of the call he was 15km from a point P which lies on a straight road and a distance of 35km from home,furthe along the road.

Sam decides to drive across country directly to some point between home and the point P on the road.

a) If the distance that Sam travels on the road is x how far does he travel across country?

b) using t=d/v obtain an expression for the total amount of time Sam spends on his journey.

c) How far does Sam need to travel on the road for his quickest route home?
What is the minimum possible time Sam can spend travelling (to the nearest minute)?

solve the triangle with a=7, b=10, and c=6, and find its area. Round all answers to the nearest tenth.
I slove all the angles by the law of cosine. (though I can do it with the law of sin)
then I got A=43.5
B=79.8
C=36.2
I have checked the value of B and C is correct, what's wrong with A of my answer?
please explain by using the law of cosine

Thanks!

let a=b then
a^2 = ab ---------- (*a both)
a^2+(a^2-2ab) =ab+(a^2-2ab) - ------- ( +(a^2-2ab) both)
then take log base 10

log(2a^2-2ab) =log(a^2-ab)
log(2(a^2-ab)) = log(a^2-ab)
log2 + log(a^2-ab) = log(a^2-ab)
log 2=0
then
log2 = log1
that mean
2 = 1

where wrong!!!!!!???
a+a = a
mean 2a =a

Let's take the problem (x^2) - 5
is the Domain: All real #'s except [ sqrt(5), -sqrt(5) ]
(is radical(5) even a real #?) If not, what is the Domain?
and How do you find the Range in general and in this particular problem?
