Clark's English students learned 30 vocabulary words. Each week, students tend to forget 10% of the vocabulary words they learned. How many of those words will they still remember in 4 weeks? (ROUND TO THE NEAREST WHOLE NUMBER) Do the following for the situation above:

Define the variables x and y.
State the Initial Value.
Is this situation Growth or Decay?
State the Growth/Decay Factor.
Write the equation that models the situation.
Determine how many vocabulary words the average student will remember in 4 weeks (ROUND to the nearest whole number).
BE SURE AND USE THE EQUATION EDITOR WHEN APPROPRIATE SUCH AS WRITING THE EQUATION

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false. (you must enter t or f -- true and false will not work.) f equation editorequation editor 1. a plane and a line either intersect or are parallel t equation editorequation editor 2. two planes parallel to a third plane are parallel f equation editorequation editor 3. two lines either intersect or are parallel f equation editorequation editor 4. two planes orthogonal to a third plane are parallel f equation editorequation editor 5. two planes orthogonal to a line are parallel f equation editorequation editor 6. two planes either intersect or are parallel f equation editorequation editor 7. two lines orthogonal to a third line are parallel t equation editorequation editor 8. two lines parallel to a third line are parallel t equation editorequation editor 9. two planes parallel to a line are parallel f equation editorequation editor 10. two lines parallel to a plane are parallel f equation editorequation editor 11. two lines orthogonal to a plane are parallel
