A length is measured as 21 cm correct to 2 significant figures. a) What is the lower bound for the length?
b) What is the upper bound for the length?

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

54.864 meters

step-by-step explanation:

once you solve it out the value of x is 13
