The amount a string stretches varies linearly with the mass applied to the spring, as can be seen in the video. in the video, with no additional mass, the hanger was 30.6 cm off the ground. with 150 grams of additional mass, the hanger was 16.2 cm off the ground. a wooden block stretched the spring so the hanger was 24.5 cm off the ground. determine the mass of the wooden block, to at least 1 decimal place.

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.
