The angle of elevation to the top of a tree, from a point 50 ft away, is 68º. How high is the tree? I help pls​

What is the slope of a line that is perpendicular to y = 3x + 1

Come up with a new linear function that has a slope that falls in the range 10 m − < < . choose two different initial values. for this new linear function, what happens to the function’s values after many iterations? are the function’s values getting close to a particular number in each case?

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.
