Answer:
-cos(x)
Step-by-step explanation:
y¹ = cos(x)
y² = -sin(x)
y³ = -cos(x)
y⁴ = sin(x)
Every 4th derivative is sin(x)
123 = 4(30) + 3
y¹²⁰ = sin(x)
y¹²¹ = cos(x)
y¹²² = -sin(x)
y¹²³ = -cos(x)
Answer:
6.2
Step-by-step explanation:
5, 6, 5, 6, 9
5+6+5+6+9 = 31
31/5 = 6.2

Answer:
Option D, ∠FBE
Step-by-step explanation:
The image for the question is attached herewith
Solution
As per the property of arc, angles subtended by the same arc (chord) on the circumference of a circle have equal measures.
∠FAE is an angle subtended by the arc FE that touches the circle at point 'A'.
∠FBE is also subtended by the arc FE at the point 'B'.
Therefore, we must have
m∠FAE = m∠FBE.
Since, m∠FAE = 72°, so m∠FBE = 72°.
Hence, option D, ∠FBE
Answer:
Opposite angles
Step-by-step explanation:
Where two lines intersect each other, the angles opposite to each other are opposite angles. Opposite angles have the same measure.
