Best ResponseYou've already chosen the best response.0i could see this as looking for the radius; which would indicate the a triangle in Q1

Best ResponseYou've already chosen the best response.0its a 345 right triangle

Best ResponseYou've already chosen the best response.0we then find the max area of a square that fits in it...maybe; or the max part of the circle to fit it

Best ResponseYou've already chosen the best response.0the equation of the line that we want is: (0,3) ; (4,0) ; the slope then being 3/4 or.... y = (3/4)x + 3 right? that is the equation for the hyp ... that line of 5

Best ResponseYou've already chosen the best response.1Her solution based on computing the area of ODC in two ways. First: 1/2*3*4 Second* 1/2*CD*r = 1/2*5*r

Best ResponseYou've already chosen the best response.0(4/3)x = (3/4)x + 3 [3] 4x = (9/4)x +9 [4] 16x = 9x + 36 25x = 36 x = 36/25 did I get that right?

Best ResponseYou've already chosen the best response.0watch; it can be; but im actually using the other side; even tho I inadvertantly flipped it; it doesnt matter if we have 4 over and 3; or 3 over and 4 up; its the same triangle just flipped on itself with the same amount of circle it it ...

amistre64

Best ResponseYou've already chosen the best response.0inflection points are where the graph stays along a course in a general direction.. sure

Best ResponseYou've already chosen the best response.1f(x)=x^4+c*x^3+x^2 what should b X so it will have 2 inflect. points? and then 1?

amistre64

Best ResponseYou've already chosen the best response.0f'= 4x^3 +3cx^2 +2x f'' = 12x^2 +6cx +2 = 0 for inflection points

amistre64

Best ResponseYou've already chosen the best response.0x, as far as I can tell, is an input and has no real effect on the graph of this thing; the constants describe the path it takes

Best ResponseYou've already chosen the best response.0f'' = 12x^2 +6cx +2 = 0 in order for this to have 2 real roots; we have to manipulate the discriminate of the quadratic formula....

Best ResponseYou've already chosen the best response.036c^2 4(2)(12) > 0 for 2 inflections 36c^2 4(2)(12) = 0 for 1 inflection

amistre64

Best ResponseYou've already chosen the best response.036c^2 96 = 0 36c^2 = 96 c^2 = 96/36 c = + sqrt(96)/6 for one inflection

Best ResponseYou've already chosen the best response.0it comes from taking the 1st and 2nd derivatives of the given equation

amistre64

Best ResponseYou've already chosen the best response.0youd have to understand a little calculus to get the idea of it; but basically I used proven methods to find when the 2nd derivative = 0

Best ResponseYou've already chosen the best response.0y = x^4+c*x^3+x^2 y' = 4x^3 +3cx^2 +2x y'' = 12x^2 +6cx +2 ; when y'' = 0 we have a point of inflection

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0y'' is a quadratic that can have its roots figured out by the quadratic formula; the discriminant of the quad formula tells us how many roots we will have

Best ResponseYou've already chosen the best response.0b^2 4ac (6c)^2  4(2)(12) 36c^2 96 has to be greater than 0 for it to have 2 points for inflection 36c^2 96 has to equal 0 for it to only have 1 point of inflection

amistre64

Best ResponseYou've already chosen the best response.0so you solve the equations of the discriminate for c..

amistre64
 5 years ago
Best ResponseYou've already chosen the best response.0if we know what c is ro get the discriminate to = 0; then we should assume that larger values of c will make it greater then 0 for 2 roots
