The graphs of y=b(x) (black), y=g(x) (green), y=p(x) (blue) and y=r(x) (red) are shown. Which of the four statements is correct?

b′(x)=−r′(x)

g′(x)=−r′(x)

b′(x)=−g′(x)

g′(x)=−p′(x)

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

df =

both have same length

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
