Calculus
A particle starts at the point (5,0) at t=0 and moves along the x-axis in such a way that at time t>0 its velocity v(t) is given by v(t)= t/(1+t^2). a). Determine the maximum velocity of the particle. Justify your answer. b). Determine the position of the particle at t=6. c...

a). 4^(-1) is the same as 1/4. Since this is the diameter, you divided it by the 2 to get the radius. So the radius is 1/8. Now the expression is: A= pi*(1/8)^2 or A=(1/64)*pi b). In part a, the expression is for the area of one punched hole. Since you have three punched holes...

1. The first thing you need to do is convert 60km to meters, or 10,000m to kilometers; whichever you prefer. Next,it helps if you draw a right triangle. The plane is at a height of 10,000m; this is the vertical leg of the triangle. It is 60 km away from the airport; this is ...

Calculus
In the interval (0 is less than or equal to x which is less than or equal to 5), the graphs of y=cos(2x) and y=sin(3x) intersect four times. Let A, B, C, and D be the x-coordinates of these points so that 0<A<B<C<D<5. Which of the definite integrals below ...

Whenever you have a number raised to a negative power, you have to divide it. So 6y^-3 becomes (6)/(y^3)

Algebra 1 HELP
So you have (8^6)/((8^4)*(8^2)). I would start with the denominator. When you are multiplying exponents with the same base, you add the exponents. So the above equation becomes (8^6)/(8^6). This simplifies to 1. For the second problem, it's slightly different. You have (4^...

Thank you!

Calculus
I'm a little confused with this integration problem: If the definite integral from 0 to 2 of (e^(x^2)) is first approximated by using two inscribed rectangles of equal width and then approximated by using the trapezoidal rule with n=2, the difference between the two ...
