So, given the polynomial
We can check if is a factor by evaluating
:
So, is not a factor.
Similarly, we can evaluate to check if
are factors:
So, only is a factor of
Answer:
Sin(t) = and
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin() =
The total snowfall for listed 10 days is 349 cm.
Further explanation:
The sum of snow fell each day will give us the total snowfall for 10 days.
Given:
Snow fell on 10 days:
14 cm, 13 cm, 7 cm, 3 cm, 11 cm, 14 cm,
