If in a question you were told to use estimation to figure out lets say √5.32x3.43+4.49 what would your answer be with working because i'm not sure how my friend got this wrong in his test despite me being a young mathematician and approving of his answer which was 4 although this was not the exact question but did add up to 19 answer with working out. you in advance

Tell whatever the ordered pair is a solution of the given system.

Lindsay is creating a bridge out of dried pasta and glue. in her plans, she sketches the graph to determine the lengths of the noodles, in centimeters, needed for the arch to increase the length of the bridge in 1 centimeter increments. which function did lindsay use to create her design? f(x) = (x – 5)2 + 8 f(x) = –(x + 5)2 + 8 f(x) = 0.5(x + 5)2 + 8 f(x) = –0.5(x – 5)2 + 8

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5)
