A hexagon will rotate onto its self at 120 degrees.
Answer:
34
Step-by-step explanation:
The given requirement is ...
t + a < 52
and we are told that t = 17. Substituting into the inequality, we have ...
17 + a < 52
a < 35

Answer:
Step-by-step explanation:
Given
Initial population was people
By 2020, it becomes people
Suppose the population follows the trend
where, is the number of years after 2014
For year 2020 it is 6. Insert the values
Thus, the exponential population trend is
Answer:
ACD and DCB are supplementary and others are correctly chosen ...
Answer:
1
Step-by-step explanation:
The function with the given zeros will factor as ...
f(x) = a(x +15)(x^2 +9) . . . . with leading coefficient 'a'
You have ...
f(2) = 221 = a(2+15)(2^2+9) = a(17)(13) = 221a
Then a = 221/221 = 1
The leading coefficient is 1.

<em>Additional comment</em>
As you know, a function with zero x=p has a factor of (x -p). The given zeros mean the function has factors (x -(-15)), (x -3i). and (x -(-3i)). The product of the last two factors is the difference of squares: (x^2 -(3i)^2) = (x^2 -(-9)) = (x^2 +9). This is how we arrived at the factorization shown above.
