Answer:
Time, t = 10 seconds.
Explanation:
<u>Given the following data;</u>
Initial velocity, u = 10 m/s
Final velocity, v = 30 m/s
Acceleration, a = 2 m/s²
To find the time, we would use the first equation of motion;
Where;
- v is the final velocity.
- u is the initial velocity.
- a is the acceleration.
- t is the time measured in seconds.
Making time, t the subject of formula, we have;
Substituting into the equation, we have;
<em>Time, t = 10 seconds.</em>
The answer is c. 10-20 seconds
Answer: 1.50
Explanation:
Isabel's portfolio beta is a weighted average of the individual stock betas.
= Weight of stock A * Stock A beta + Weight of stock B * Stock B beta + Weight of stock n * Stock n beta
= (20% * 0.4) + (30% * 1.2) + ( 25% * 2.5) + (25% * 1.75)
= 0.08 + 0.36 + 0.625 + 0.4375
= 1.5025
= 1.50
