The distance that a spring will stretch varies directly as the force applied to the spring. A force of 6060 pounds is needed to stretch a spring 66 inches. What force is required to stretch the spring 1414 inches?

Forced need to stretch 1414 inches = 129830.91 pounds

Step-by-step explanation:

Force ∝ Distance

F = KD where K is constant of proportionality

K = F/D = 6060/66 = 91.818182

Hence Force needed to stretch 1414 inches =

F = 6060/66 x 1414 = 129830.91 pounds

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
