x=position of ball  xo= original position of ball   vo = original velocity    t = time   a = acceleration of gravity 9.8 m/s^2

x=xo + vot + 1/2 a t^2    note the vo and a are DOWNWARD in this example and thus NEGATIVE

x = 60 + -3(1) + 1/2 (-9.8)(1^2)

x = 60 -3 -4.9 = 52.1 m above the ground  or 7.9 m down from its original position

The ratio of 'a' to 'b'  is expressed as   a/b   as a fraction.

Huh?      Did you mean convert degrees C to F?

F =  9/5 C + 32       9/5 (23) + 32 =   well, just use the calculator !

Possibly....if you give us the table of numbers.....

Just multiply  3/5   x  2500  

= 1500 allowable

(1/2) / 3   =   (1/2) / (3/1)  =  1/2  x  1/3  =  1/6

12 /x     as 'x'  APPROACHES  0   the value APPROACHES infinity.   Melody is correct....dividing by 0 is 'undefined'  or not allowed.

3x + 2  = x+ 2x + 2

3x + 2 = 3x + 2             any value of x will work

Well     tan a  =  sina / cosa    for small angles cosa ~ 1  thus   tana = ~ sina /1 = sin a

.9 tana =  sina

tana / sina = 1/ .9

1/cosa = 1/.9

.9 = cosa    a =25.84 degrees     Tan 25.84 = .484     sin 25.84 = .4358

3x + 1 < 0

3x  <  -1

x  < - 1/3       so for any value of x less than -1/3 the answer to the equation will be negative

pick one value of 'x'    x = -2    -2^2 = 4
