the function f(t) = 0.000468x4 - 0.016x3 + 0.095x2 + 0.806x. Evaluate f (t) for t = 4 and t = 17, and describe what the values of the function represent.

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle
