Malia is placing a barrier around the edge of a circular path with the diameter of 13 M the barrier are in length of 2.5 M.

1 answer:

7 0

The circumference of a circle of diameter 13 m is 13π m, about 40.82 m.

(40.82 m)/(2.5 m) = 16.328

16 may be the best approximation of the number of pieces Malia will need. 17 pieces will make a barrier that is longer (larger diameter) than is needed.

siniylev [52]

$y=x^2-3x+2 \\y=4x-4$

A. (1, 0) and (–6, –28)

B. (1, 20) and (6, 0)

C. (1, 0) and (6, 20)

D. no solution

Correct answer is C.

$y=x^2-3x+2 \\y=4x-4\\ \\4x-4=x^2-3x+2 \\x^2-7x+6=0 \\x^2-6x-x+6=0 \\x(x-6)-(x-6)=0 \\(x-6)(x-1)=0 \\x=6\,\text{ or }x=1 \\y=4\times 6-4=20 \,\text{ or }y=4\times 1-4=0 \\ \\(6,20)\,\text{ and }(1,0)$
