hi guys, im stuck on this question, if anyone can help me out i would really appreciate it ! Q: The market demand and supply curves for an agricultural product are as follows: Qd = 4500-250P and Qs = 200p where quantities are in thousands of bushels per annum and price is in ...

Would someone clarify this for me... Is antiderivatives just another name for intergral and why is intergral of a function is the area under the curve? Antiderivatives is another word for integral. Why area? THink on this...the integral is the sum of all the "heights" times ...

Find the area of the region bounded by the parabola y=x^2, the tangent line to this parabola at (1,1) and the x-axis. I don't really get what this question is asking. It looks like the area of right triangle to me...try the graph, and shade the area under the tangent. Find out...

economics-worked out, need confirmation
hey ppl i have already done he working out and need ppl to just confirm my working out etc. Q: The market demand and supply curves for an agricultural product are as follows: Qd = 4500-250P and Qs = 200p where quantities are in thousands of bushels per annum and price is in ...

The geometric mean of two postitive numbers a and b is sqrt(ab). Show that for f(x) = 1/x on any interval [a,b] of positive numbers, the value of c in the conclusion of the mean value theorem is c = sqrt(ab) I have no idea how to do this! If the mean of a and b is sqrt(ab), ...

I am doing the AP calculus review, these are the questions I have no Idea on how to do: 1. if 0<= k <=pi/2 and the area under the curve y-cosx from x=k to x=pi/2 is 0.2, then k= 2. let F(x) be an antiderivative of (ln x)^4/x If F(1)=0, then F(9)= 3. What is the equation ...

We're doing areas by integrals now, with 2 eqns. I have a few questions. 1. Sketch the region in the xy-plane defined by the inequalities x-2(y^2)> 0 and 1-x-abs(y)>0. and find its area. Would it be best to solve for x, then graph it as x= something? Then find the ...

The area under a force-versus-time curve is: a) momentum b) impulse c) velocity what's the area under a force-vs-time curve: momentum, impulse, or velocity?

When the force F acting on a particle depends only on the particle's position coordinate x, and when the particle moves along the x-axis, then the work done by the force is the area under: a) F versus x curve b) F versus v curve (v is velocity) c) F versus a curve (a is ...

what's the area under a force-vs-time curve: momentum, impulse, or velocity? Impulse. (It happens to equal the change in momentum, as well) i thought so.. thanks for the clarification.

CALC - area under a curve
You have an unknown function that is monotone increasing for 1<x<5 and have the following information about the function values. With the clear understanding that there is no way to get an exact integral, how would you try and approximate the area under the curve? X=(1, ...

Calc 2: Area under the curve
Find the area of the region enclosed between y=2sin(x and y=3cos(x) from x=0 to x=0.4pi Hint: Notice that this region consists of two parts. Notice: I'm getting 1.73762 but apparently that is wrong.

Calc 2: Area under the curve
Find x where 2sin(x)=3cos(x) (div by cos) 2tan(x)=3 tan(x)=1.5 x=56.31degr Area(from x=0 to x=56.31)= (3sin(56.31)+2cos(56.31)-(3sin(0)+2cos(0)) =3.60555-2=1.60555 Area(from x=56.31 to x=72)= (-2cos(72)-3sin(72))-(-2cos(56.31)-3sin(56.31))=-3.47120-(-3.60555)=0.13435 The total...
