What is the area bounded by the graphs y=3e^x, y=3-x^2, y=2x, and x=2

This one is a little tricky. First graph all functions/lines. Then find region that is bounded by all functions/lines. The region I found is shaded in link below: http://www.flickr.com/photos/56185495

A square is cut into two equal rectangles, each with perimeter 36. Find the area of the square.-If x is one side of the square, one side of the rectangle is x and the other is x/2, so the equation of

Help on a math problem please

Explain how you got your answer please. 1) Find the equation of the line in slope-intercept form that is parallel to the line 2x+y= -5 and contains the point (3, -1) Thanks everyone. I got 2x+y=5 b

Math Summation Proof....Simple

1 + 2 + 3 + .... + i - 2 + i - 1 = [( i - 1)i]/2 Prove with gory detail please.-Let K = 1 + 2 + 3 + .... + (i - 2) + (i - 1) now, use the commutative property of addition to write K = (i-1)+(i-2)+

Slope and y-intercept

Write the slope intercept form for the equation of a line with the given slope and y intercept. M = -1; y-int: (0,0) I did the problem but Im not sure do you show the 0?-The slope intercept form is

What i really mean is that should i go up by for this graph on the y axis? Its from $2000 to about a million dollars but i dont know how much to do up by, and i only have 30 spaces, i could possibly c

Linear Algebra Eigenvalue

Is λ = -3 an eigenvalue of [-1 4 ; 6 9]? Why or why not? Thanks!-| -1+3 4 ;69+3 | = (-1+3)(9+3) - (6*4) = 30 != 0.Therefore -3 is not an eigenvalue. [Ed.What a mistake.(-1+3)(9+3) - (6*4) should be

Discontinuity, first year calc

is the discontinuity of (e^(2x) -1) / (e^x - 1) at x= 0 removable? if not explain why not, and if yes, give a value for f(0) that will make f(x) continuous ok so im confused, so the limits as x approa

Differentiation speed as a function of concentration

Concentration c as a function of distance r from the center satisfies c(r) = 1/r Distance as a function of time t satisfies r(t) = (10 - t)^(2/3) Speed s as a function of time t satisfies s(t)

What do they want for this math problem and how do I solve it

5(12-3p) = 15p+60-First you distribute the 5: (5 x 12) - (5 x 3p) = 15p + 60 60 - 15p = 15p + 60 Then you get the variable all on one side and the non-variable all on one side: 60 - 15p + 15p = 15p +
