Answer:
hey
Step-by-step explanation:
formula used here
see the attachment above
option c
(2 - π) / 4
cos⁻¹(- √3 /2)) = cos⁻¹ (-0.866) = 150°
sin 150° = 0.5 = 1/2
sin (- π /2) = -1
tan (sin (- π /2)) = tan (-1) = - 45° = - π / 4
1/2 + (- π /4) = (2 - π) / 4
Set each set of parentheses to 0 and solve for x.
X—6 = 0
X = 6
X + 5 = 0
X = -5
X-9 = 0
X = 9
The zeros are 6, -5, 9
rounded to the nearest 10 is 840
rounded to the nearest 100 is 800
here you are the answer.
