Find all values of x for which the tangent line ot y=2x^3-x^2 is perpendicular to the line x +4y=10?

math
let θ(in radians) be an acute angle in a right triangle, and let x and y, respectively, be the lenghts of the sides adjacent and opposite θ. suppose also that both x and y vary with time how are dθ/dt, dx/dt, and dy/dt related?

3 5 7 are odd and consecutive-- they add to 15 which is greater than 10 and less than 20.

Algebra
y- intercept is b in the formula y=mx+b hence your y intercept is 7/2.

Algebra
y=mx+b and m is the slope rearrange the equation so you can find what y equals. in this case you would rearrange it to equal y=-5x/2+7/2. so your slope is -5/2.

Calculus
Assume that x>0 and y>0. If y=5sqrt{x+9} and dx/dt = 2, find dy/dt when x=7.

Please advise on the following: From 1993 to 2003 the cumulative number N of AIDS cases in thousands can be approximated by, where corresponds to the year 1993. N = -2 x2 + 76x + 430, where x = 0 corresponds to. 1) Show how well the equation approximates the data. 2) Rewrite t...
