ANSWER : D
EXPLANATION : 81 > 13 is true
Answer:
8.0
Step-by-step explanation:
The attached shows guesses until we have an answer accurate to 6 decimal places. Rounded to 1 decimal place, the answer is 8.0 years.
This (8 years) was our initial guess, based on the "rule of 72" which says the doubling time for 9% interest is 72/9 = 8 years.
Our second guess, at 8.1, was farther away from the doubled value, so the first guess at 8.0 is closer.
t = 8.0
The horizontal and vertical vector components of the velocity vector V, namely Vx and Vy are; 505.32 ft/s and 721.57 ft/s respectively
<h3>Horizontal and Vertical components of vectors</h3>
For ease of computation since vectors have magnitude and direction; they are resolved into horizontal and vertical components.
By convention, the horizontal, Vx and vertical components, Vy are as follows;
- Vx = V cos π
- Vy = V sin π
where π = angle of inclination to the horizontal.
Hence,
- Vx = 881 × cos55° = 505.32 ft/s
- Vy = 881 × sin55° = 721.57 ft/s
