Ok guys : use the information provided to write the vertex form equation of each parabola y=-12x^2+192x-769 explain this is a grade
2)solve each equation by completing the square : n^2+16n-74=-3
3)solve each equation by factoring: 6n^2+48n+90=0

Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 5 and another leg measuring 14. an angle across from the leg measuring 5 is marked y degrees. numerical answers expected!

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.

Suppose that the function f is defined. , for all real numbers, as follows. _ \ 1/4x² -4 if x≠ -2 f(x)=< /_-1 if x=-2 find f(-5), f(-2), and f(4)
