Answer:
0.447 sec
Explanation:
velocity = distance/ time
distance 'h' is a function of time 't' given by
⇒ differentiating equation
⇒ velocity = 
⇒ acceleration = 
= 24 
deceleration due to gravity = -9.8 m/
= - 9.8 x 3.281 = - 32.154 ft/
Net deceleration = 24 - 32.154 = - 8.15 ft/
at maximum height v = 0
= 
+ 2ah
⇒ 0 = 
+ 2 (-8.15)h
⇒ h = 118.72 ft⇒
118.72 = 12
+ 44t + 16
⇒ 
- 102.72 = 0
⇒ t = -44 ± 
/ (2 x 12)
t = 0.447 sec
Answer: 1.9%
Explanation:
First derive the Market return as this is needed in the Capital Asset Pricing Model by using the same model:
Required return = Risk free rate + Beta * ( market return - Risk free rate)
Using stock Y:
12.4% = Risk free rate + 1 * (market return - Risk free rate)
12.4% = Rf + market return - Rf
Market return = 12.4%
Use this to calculate the Risk free rate:
Stock Z:
8.2% = Rf + 0.6 * (12.4% - Rf)
8.2% = Rf + 7.44% - 0.6Rf
Rf - 0.6Rf = 8.2% - 7.44%
0.4Rf = 0.76%
Rf = 0.76% / 0.4
= 1.9%
Answer:
Abstraction.
Explanation:
This is an abstraction because Donna generalized a concept — reporting the title or price of a book — to apply to all types of books. Noticing repeated details or common features and removing them is a key element of abstraction.
