HELP. WILL GIVE BRAINLIEST, WHEN ANSWERED.
maxonik [38]

Answer:

√89 or 9.43 units is the distance between Sophia's house and library

Step-by-step explanation:

H (1 ,1)  ⇒ House

L(6 , 9) ⇒ Library

Leg₁ = OH = 6 - 1 = 5 units

Leg₂ = OL = 9 - 1 = 8 units

<h3>  Pythagorean theorem;</h3>

            Hypotenuse² = leg₁² + leg₂²

                                   = 5² + 8²

                                    = 25 + 64

                                    = 89

              hypotenuse = √89 units  (radical form)

               hypotenuse = 9.43 units

Answer:

The equation for height is given as  

S= -16t2 +V 0 t

Also given

V0 = 128 ft/s

Substituting   192 = -16t2 +128t

Which is simplified as

t2 -8t +12 =0

Which gives t = -2 sec and  t= 6 sec ( -2 can be ignored)

Using S = -16 *6*6 +128 *6 = 192 ft
