I have another question for u guys could u plz help me out? so here it is? Anthony threw a ball from the top of a 10-story building that was 165 feet tall. The equation g(165-h)=1/2v^2 can be used to find the maximum height the ball can attain after being thrown from the top of the building. In this equation g represents the acceleration due to gravity (32 feet per second squared), h is the maximum height attained by the ball, and v is the speed of the ball. rewrite the equation to highlight the maximum height attained by the ball, h.

There are four steps for converting the equation x2 + y2 + 12x + 2y – 1 = 0 into standard form by completing the square. complete the last step. group the x terms together and the y terms together, and move the constant term to the other side of the equation. x²+ 12x + y²+ 2y = 1 determine (b ÷ 2)2 for the x and y terms. (12 ÷ 2)2 = 36 and (2 ÷ 2)2 = 1 add the values to both sides of the equation. x2 + 12x + 36 + y2 + 2y + 1 = 1 + 36 + 1 write each trinomial as a binomial squared, and simplify the right side. (x + )2 + (y + )2 =
