ugh this is bugging me
that i cant do
someone help?!

1. During a science experiment, Hal drops a ball from a 25-foot-high balcony. How long does the ball take to reach the ground?
   A. 1 second
   B. 1.5 seconds
   C. 1.75 seconds
   D. 3.5 seconds
   E. 5 seconds
2. Which argument uses inductive reasoning?
   I. The next number in the pattern 1, 4, 9, 16, 25, … is 36
   II. A quadrilateral with four right angles is a rectangle. A square has four right angles. Therefore, all squares are rectangles.
   III. I constructed several equilateral triangles and measured 60°. Therefore, the angles in all equilateral triangles measure 60°.
   
   A. “I” only
   B. “II” only
   C. “III” only
   D. “I” and “III” only
   E. “II” and “III” only
3. What is the hypothesis in the following logical argument?
   
   All regular hexagons have 6 congruent sides. ABCDEF is a regular hexagon. Therefore, ABCDEF has six congruent sides.
   
   A. Regular hexagons have six congruent sides
   B. ABCDEF is a regular hexagon
   C. ABCDEF has six congruent sides
   D. ABCDEF is a regular hexagon. Therefore, ABCDEF has six congruent sides.
   E. Not here.
4. Which x-value provides a counterexample to the following statement?
   For any real number x, x^2 ³ x
   A. x= 4
   B. x= ½
   C. x= 0
   D. x= -1
   E. Not here.
5. Which property justifies adding –3 to both sides of an equation? Choose the best answer.
   A. Addition Prop. Of Equality
