Answer:
A
Step-by-step explanation:
The TV to have a 16:9 ratio and have a diagonal of 65 inches must have a length & width whose squares add to 4,225 (65 squared) and whose ratio length and width simplifies to 16/9.
B is not an option because
.
C is not an option because
which is 1.777777777778 as a decimal.
D fails for the same reason as C.
Therefore A is the solution because
and 
To calculate time at t= 2 minutes. We substitute at t = 2.
h = 10.5 + 6.5 sin(850t)
h = 10.5 + 6.5 sin (850 * 2)
h = 10.5 - 6.4012 = 4.1 feet
Hence at time t = 2, height = 4.1 feet.
