A ball is dropped from the top of a building that is 250 feet tall. The
Virty [35]

hi

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

  t² = -175 /-16

 t² = 175/16

Here there si two solutions :  t = \sqrt{175/16}   and  t =  - \sqrt{175/16}

However, as time cannot rewind,  we will  keep only positive solution

So t = \sqrt{175/16}

   

in seconds  it will be  :  3.3 seconds

If cosΦ = 5/13<br><br>what is, sin Φ/sin Φ + cos Φ<br>​
alexandr402 [8]

Answer:

sin Φ/(sin Φ + cos Φ) = 12/17

Step-by-step explanation:

sin Φ = 12/13

then sin Φ + cos Φ = 12/13 + 5/13

= 17/13

So , sin Φ/(sin Φ + cos Φ) = 12/13 ÷ 17/13

= 12/13 × 13/17

= 12/17
