If the digits of a number may be any one of 0 through 9 (except the first digit cannot be zero), and the system of alternating signs of coefficients is used to create a polynomial, what is the least number m of real zeros the polynomial can have? What is the greatest number M ...
A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions W inches by L inches by cutting out equal squares of side x at each corner and then folding up the sides. (W = 12 in. and L = 20 in). Find the values of x for which the volume is ...
I am a 2-digit number with a 1-digit decimal. I am bigger than 54 but smaller than 56. 2 of my digits are even. When you divide my whole number by the digit in my decimal place, the answer has no remainder. What are the biggest and smallest numbers I could be?
I have this integral that I don't know how to solve: ∫ (x-3)/sqrt(x) Would I multiply both parentheses first? or just turn it into (x-3)(x^-0.5)?
okay so there must be a mistake with the system, thanks for clearing that up Damon.
Using an upper-case "C" for any arbitrary constants, find the general indefinite integral ∫ (-2-t)(-9-t^2) dt Now I multiplied both parentheses to get: ∫ (18 + 2t^2 + 9t + t^3) dt now I integrated and got: 18t + 2t^3/3 + 9t^2/2 + t^4/4 + C but I'm tol...
2x-5=39 2x=39-5 2x=34 x=17
come on i waitied almost for 20 minutes and this is what i get. -_- not cool
