which expression finds the measure of an angle that is coterminal with a 126° angle? 126° (275n)°, for any integer n 126° (375n)
2 answers:
Answer:
126° ± (720n)°
Step-by-step explanation:
Coterminal Angles are the angles that share the same initial side and terminal sides of the given angle.
Also, for finding coterminal angles we add or subtract the multiple of 360° ( when angle is given in degress ) or ( When angle is given in radians )
For example : The coterminal angles of an angle Ф are,
Ф ± (360n)°
Where, n is a non zero positive integer,
Here, Ф = 126°,
So, the coterminal angle of 126° are,
126° ± (360n)°
Since, n is an integer,
⇒ 2n is also an integer,
Thus, the coterminal angle of 126° are
126° ± (360×2n)°
⇒ 126° ± (720n)°
For any integer n.
Last option is correct.

Answer:
Therefore,
The Central Angle is 48°.
Step-by-step explanation:
Given:
Circumference = 12 units
To Find:
Central angle = θ = ?
Solution:
If "θ" the central angle is in degree then arc of length is given by
Substituting the values we get
Therefore,
The Central Angle is 48°.
Answer:
Step-by-step explanation:
A). An investment account earns 2.8% simple interest.
Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.
B). The price of a stock varies by 2.8% each week.
Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.
Therefore, the answer is NEITHER.
C). An investment account earns 2.8% compound interest, compounded monthly.
Formula to get the value of the final amount in the account is,
Final value = Initial value ×
Here 't' = Duration of investment
It's an EXPONENTIAL FUNCTION.
