Answer:
c. 55.4 ft/s
Step-by-step explanation:
Speed of the object is represented by the function:
where x represents the number of feet the object has fallen. We have to find the speed of the object after it has fallen 48 feet. This means we have to find f(x) for x = 48. Substituting x = 48 in above equation we get:
Thus, rounded to nearest tenth, the speed of the object after it has fallen 48 feet would be 55.4 ft/s
Solving the expression we get value of x:
Step-by-step explanation:
We need to solve the equation and find value of x
Solving:
Multiply -2 with terms inside the bracket
Solving |1-3| we get |-2|=2
Multiply (-) sign with terms inside the bracket
Multiply 2x with 18
Add 36x on both sdides
Add 6 on both sides:
Divide both sides by 38
Simplifying:
So, Solving the expression we get value of x:
