Answer:
First pilot will gain altitude faster by 7.16 mph than second pilot.
Step-by-step explanation:
In this question we will calculate the y component of the velocity by which the pilots are gaining height. Means we will analyze which pilot will gain the altitude early.
For the first pilot vertical component of the velocity will be
v = 400 × sin30° = 400 × (1/2) = 200 mph
For second pilot vertical component of the speed is
v' = 300 × sin40° = 300 × (0.642) = 192.84 mph
Therefore pilot 1 will gain altitude faster then pilot 2 by
200 - 192.84 = 7.16 mph.
Answer:
We have been given many sequences below:
The sequence is said to be geometric if there is same ratio between consecutive terms
So we will check all the sequences one by one:
(1) 
.
Hence, geometric
(2) 
Hence, geometric.
(3) 
Hence, geometric.
(4) 
Hence, geometric.
(5) 
Ratio is not same hence, not geometric.
Answer:
10D
Step-by-step explanation:
3D is DDD, 7D is DDDDDDD, add those D's together and you have 10D, DDDDDDDDDD
You make the denominators into common factors (the same numbers( and subtract them like that
Answer:
The first graph.
Step-by-step explanation:
An exponential function has a graph that is a smooth curve; it either increases at an ever increasing rate or decreases at an ever increasing rate.
The only graph that fits these characteristics is the first one.
