A solid lies between planes perpendicular to the x-axis at xequalsminus4 and xequals4. The cross-sections perpendicular to the x-axis between these planes are squares whose bases run from the semicircle y equals negative StartRoot 16 minus x squared EndRoot to the semicircle y equals StartRoot 16 minus x squared EndRoot. Find the volume of the solid.

Line gh passes through points (2, 5) and (6, 9). which equation represents line gh? y = x + 3 y = x – 3 y = 3x + 3 y = 3x – 3

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
