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

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?
maxonik [38]
First you need to simplify the left side of the equation to get 2x-2 \geq -12
Then you add by two on both sides to get 2x \geq -10
Finally you divide by 2 on both sides to get x \geq -5
