Answer: 8.73 ft/s
Step-by-step explanation:
We have the following equation that models the motion of the rock:
Where is the height of the rock at a time .
Now, if we can find and then the velocity of the rock at that height:
Rearranging the equation:
Multiplying the equation by -1:
Solving with the quadratic formula , where , ,
.
Choosing the positive result of the equation:
Since velocity is defined as the traveled distance in a given time , we have:
This is the velocity of the rock at the height of 48 feet
Answer:
no solution
Step-by-step explanation:
3+6b= 6b +5
subtract 6b from both sides
3=5
since three can't equal five there is no solution
Hey there!
We have to multiply, the "a" becomes a "negative a" ; solve this fraction to understand this step
Like: (multiplication) -a = 1/8
Let's multiply by a negative one on each of your sides
a = -(1/8)
* 1. * 1
Solve this and that gives us our answer⬆️
We have "two solutions " in this problem, which 1/8 or -1/8
Answer: 1/8 or -1/8 (option A)
Good luck on your assignment and enjoy your day
