To find

, we find the first few derivatives and observe the pattern that occurs.

As can be seen above, it can be seen that the continuos derivative of sin (x) is a sequence which repeats after every four terms.
Thus,

Therefore,

.
X=46
Explanation:
You just have to make 3x-28 and x+64 equal to each other and x would be 46.
m∠1=44
Explanation:
You just have to subtract the 46 that u solved earlier from 90 degree so it’s 44
Answer:
P=1/65.
Step-by-step explanation:
We knaow that one coin in a collection of 65 has two heads. If a coin, chosen at random from the lot and then tossed, turns up heads 6 times in a row. We calculate the probability that it is the two-headed coin.
We calculate the number of possible combinations:

Number of favorable combinations is 1.
Therefore, the probability is
P=1/65.
