Answer:
hello :
Step-by-step explanation:
f(x)=|x²-x-2|
f(x) = x²-x-2 if : x²-x-2 ≥ 0
f(x) = - (x²-x-2) if : x²-x-2 ≤ 0
x²-x-2 = ( x+1)(x-2)
sign of : x²-x-2 is :
x²-x-2 ≥ 0 : x≤ -1 or x ≥ 2
x²-x-2 ≤ 0 : -1 ≤ x ≤ 2
Answer:
7 miles a day
Step-by-step explanation:
C = 2 pi r
c = 2(3.14)(1/4)
c = 1/2(3.14) = 1.57 miles
d = rt
1.57 = 2a
.785 = a
$3.72 because 7.85 x .8 = 6.28 and 10 - 6.28 = 3.72
