A counterexample for the statement 'All square roots are irrational numbers.' is the square root of 9.  This is because when simplified, the answer is 3.  

For a number to be irrational, it can't be expressed in fractional form.  However, 3 can be expressed in fractional form as 3/1.

Sam has a total score of 500 on a game, compared to the maximum possible score of 1200.
laiz [17]
So for this all you have to do is put 500 over 1200 like this: 500/1200 and then divide 500 by 1200 to get a decimal which would be .416 .To get the percentage you have to multiply by 100 and get 41.6%. They want the nearest integer so the answer would be about 42% :)

A bullet is fired into the air with an initial velocity of 881 feet per second at an angle of 55° from the horizontal. Find the
snow_lady [41]

The horizontal and vertical vector components of the velocity vector V, namely Vx and Vy are; 505.32 ft/s and 721.57 ft/s respectively

<h3>Horizontal and Vertical components of vectors</h3>

For ease of computation since vectors have magnitude and direction; they are resolved into horizontal and vertical components.

By convention, the horizontal, Vx and vertical components, Vy are as follows;

  • Vx = V cos π
  • Vy = V sin π

where π = angle of inclination to the horizontal.

Hence,

  • Vx = 881 × cos55° = 505.32 ft/s

  • Vy = 881 × sin55° = 721.57 ft/s
