Answer: B, D, and E
<u>Step-by-step explanation:</u>
f(x) = x² - 1
(0, 1): 1 = (0)² - 1 ⇒ 1 = -1 FALSE
(1, 0): 0 = (1)² - 1 ⇒ 0 = 0 TRUE
(3, 5): 5 = (3)² - 1 ⇒ 5 = 8 FALSE
(5, 24): 24 = (5)² - 1 ⇒ 24 = 24 TRUE
(-2, 3): 3 = (-2)² - 1 ⇒ 3 = 3 TRUE
(-4, -17): -17 = (-4)² - 1 ⇒ -17 = 15 FALSE
Answer:
- 5.8206 cm
- 10.528 cm
- 23.056 cm^2
Step-by-step explanation:
(a) The Law of Sines can be used to find BD.
BD/sin(48°) = BD/sin(50°)
BD = (6 cm)(sin(48°)/sin(60°)) ≈ 5.82064 cm
__
(b) We can use the Law of Cosines to find AD.
AD^2 = AB^2 +BD^2 -2·AB·BD·cos(98°) . . . . . angle ABD = 48°+50°
AD^2 ≈ 110.841
AD ≈ √110.841 ≈ 10.5281 . . . cm
__
(c) The area of ∆ABD can be found using the formula ...
A = ab·sin(θ)/2 . . . . . where a=AB, b=BD, θ = 98°
A = (8 cm)(5.82064 cm)sin(98°)/2 ≈ 23.0560 cm^2
_____
Angle ABD is the external angle of ∆BCD that is the sum of the remote interior angles BCD and BDC. Hence ∠ABD = 48° +50° = 98°.
