The run-off next to a race track is described by the area enclosed between the curve y=x(x-10)^2+2x^4 and the curve y=2x^4 where x and y are measured in metres. Find the area of the run-off, establish
Suppose you want to eat lunch at a popular restaurant. The restaurant does not take reservations, so there is usually a waiting time before you can be seated. Let x represent the length of time waitin
how to find the points of intersection for the curves y=x^2 and y=x+2
i know they are (-1,1) AND (2,4) BUT HOW DO U GET THIS?-x^2 = x+2
x^2-x-2=0
Solve it using quadratic formula for least headache
x
If I owe $161,965.21 on my house, my interest rate is 4.5%, it was a 20 year loan a year ago when it started (I think the loan was about $171,000 a year ago) – my principal and interest due every mont
The measure one acute angle of a right triangle is 30 degrees more than twice the measure of the other acute angle. Find the measures of the angles-30+2a+a=90
3a+30=90
3a=60
a=20
30+2*20 =70
The question asks: 121.5 is 45% of what number?
I did 121.5=.45x x=270
is that right? Thank you in advance!-Yeah, to check it divide 121.5 by 270. gives you 45%-Kudos to seeing that someone actually
solve by factorization,by completing the square or by quadratic formula but more preferably by factorization-Discriminant = √[(2√6)^2 - 4 * 3 * 2] = 0
=> 3x^2 + 2√6x + 2 is a perfect square and is
= (
Please & Thanks!-First integer: x
Second integer: x+1
x = 2(x+1) + 5
x = 2x + 2 + 5
x = -7
So the two integers are -7 and -6-x+1 = yx = lower integer, y = higher
x=5+2y
(5+2y)+1 = y
6 = -y
y =
GRE scores are normally distributed with a mean μ = 500 and a standard deviation of σ = 100. A sample of size n = 25 is drawn from this distribution.

f(x,y,z) = (x+y+z)^r/(x^2+y^2+z^2) if (x,y,z) is not equal to (0,0,0), and 0 if otherwise.
Suppose that r is less than or equal to 2. Show that the lim of f(x,y,z) at (x,y,z) -> (0,0,0) does not exi
Assuming the graph of y=x²-8x-7 has been drawn, find the equation of the line which should be drawn to solve the equation 2x²=16x+2
I tried so many times but i keep getting it wrong! The answer is y=
As in algebra.-In a recursive function, the function is obtained from multiple functions combined, in a explicit function, one variable is expressed in terms of another.
So d/dx ln x = 1/x
But∫1/x = ln |u| + c
What is the | | for?I mean, I know that it means absolute value, but why is it there?
Btw, the text Im working from uses these, but WolframAlpha didnt.-d/dx l
thank you ever so much !-Just divide by 10.
$19.50-what is 10% it is just 10/100 = 1/10
So 10% of 195 is what? It is one tenth of 195. In other words 195/10 = 19.5(19.5*10=195)-19.5
