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.
The rules of operations to simplify 2 3-4 (5.4)
Answer:

Step-by-step explanation:
we are given two temperature
4 degrees and -10 degrees
since it says to figure out the changed
substract

remove parentheses and change its sign

simplify addition:

and we are done!
