Answer:
see explanation
Step-by-step explanation:
given
f'(x) = 12cos x - 4sin x, then
f'(
) = 12cos(
) - 4sin(
)
[ cos(
) = -cos(
), sin(
= - sin(
) ]
= -12cos(
) + 4sin(
)
= - 12 ×
+ 4 × 
= - 6 + 2
≈ - 2.536 ( 3 dec. places )
Answer:
is first one and last one
Step-by-step explanation:
(a) m∠RQS = (1/2)m∠QPR = 37°
(b) m∠QPR = m(arc QR) = 74° . . . . . an arc has the same measure as its central angle
