A 10-question multiple choice test has 4 possible answers for each question. A student guesses on all ten answer. a)What is the probability that the student selects at least 6 correct answers? b)Is getting exactly 10 questions correct the same probability...

find the area of the region bounded by the graphs of y=-x^2+5x+2 and y=2

Find the area of the region bounded by the curves of y=sin^-1(x/4), y=0, and x=4 obtained by integrating with respect to y. Your work must include the definite integral and the anti-derivative. I am really confused on this question. I graphed all of the p...

Set up, but do not evaluate, the integral which gives the volume when the region bounded by the curves y = Ln(x), y = 1, and x = 1 is revolved around the line y = -1. ANSWER: v = ∫[1,e] π(4-(lnx+1)^2) dx

The slope of the tangent to a curve at any point (x, y) on the curve is -x/y . Find the equation of the curve if the point (3,-4) on the curve.

The table below gives selected values for the function f(x). Use a trapezoidal estimation, with 6 trapezoids to approximate the value of integral from 1 to 2 f(x) dx =.1*4/2+.1*7/2+.3*10/2+.2*13/2+.2(15/2)+.1*18/2 =4.40

Using 4 equal-width intervals, show that the trapezoidal rule is the average of the upper and lower sum estimates for the integral from 0 to 4 of x squared, dx.

THANK YOU!!!!!!!

thank you!

Yes I do see the relation, but I don't understand what to do next.

thanks!

Really that is all? I guess I was over complicating it. Thank you!

Thank you!
