**Math HELP!**

Use brackets to show when the denominator ends I think you meant 4c^2/(4c^2-8c+4)( 4c-4)/2c , which is = 4c^2/(4(c^2 - 2c + 1)(4)(c-1)/(2c) = 4c^2/(4(c- 1)^2(4)(c-1)/(2c) now things cancel rather nicely final result 2c/(c-1) , c ≠ 1,0

following the hints suggested: let the point be (c,c^2 + 1) dy/dx = 2x so at (c,c^2+1) the slope of the tangent is 2c let the tangent equation be y = mx + b y = 2cx + b for our point, c^2 + 1 = 2c(c) + b b = 1-c^2 so the tangent equation is y = 2cx + 1-c^2 at the x-intercept, ...

**Physics**

The third charge should be placed between the +4C and +6C charges so that the forces cancel out. That will NOT be to the left of the 4C charge. If x1 and x2 are the distances to the +4 and +6 charges, 4/x1^2 = 6/x2^2 (x2/x1)^2 = 3/2 x2/x1 = 1.225 x1/(x1 + x2) = 1/2.225 = 0.449

OK. 4cos^2x-4cosx+1=0 find all angles and name 8 angles Let c=cos(x), then the equation becomes 4c²-4c+1=0 (2c-1)²=0 So c=1/2, or cos(x)=1/2 If you look at the graph of cos(x), you will find that cos(x)=1/2 occurs at π/3 and 5π/3. So the general solution is x=&...

Recall the formula for discriminant. For a quadratic equation in the general form, ax^2 + bx + c = 0, D = b^2 - 4ac if D = 0 : real, equal/double root D > 0 : two real, unequal roots D < 0 : two imaginary roots Since we're required to have one real root, we equate D to ...
