Answer:

Step-by-step explanation:

f(x) = 2x^2 + 1

f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3

Please help me!! I am struggling... I will not accept nonsense answers!
telo118 [61]

Answer:

y = 110°

Step-by-step explanation:

The inscribed angle CHF is half the measure of its intercepted arc CDF

The 3 arcs in the circle = 360°, thus

arc CDF = 360° - 160° - 60° = 140°, so

∠ CHF = 0.5 × 140° = 70°

∠ CHF and ∠ y are adjacent angles and supplementary, thus

y = 180° - 70° = 110°
