The formula y = 64h gives the velocity v in feet per second of an object that has fallen h feet. find the
velocity of an object that has fallen 92 feet. round to the nearest hundredth.

The  velocity of the object is 76.73 ft/sec

Step-by-step explanation:

* Lets explain how to solve the problem

- The formula y = √(64h) gives the velocity y in feet per second of an

 object that has fallen h feet

- To find the velocity of an object that has fallen 92 feet substitute h

  by 92 in the formula

∵ y = √(64h)

∵ h = 92 feet

∴ y = √64(92) = √5888 ≅ 76.73 feet/seconds

* The  velocity of the object is 76.73 ft/sec

step-by-step explanation:

1st step

add 3+6

=9

multipy 9*3

=37

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
