What is the approximate total length of iron edging needed to create the square frame and the two diagonals?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

d is the only accurate one

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
