Answer:
Step-by-step explanation:
1). In ΔABC,
For angle A as a reference angle,
Opposite side of ∠A → BC
Adjacent side of ∠A → AC
Hypotenuse → AB
2). By using tangent ratio in ΔYWZ,
tan(72°) = 
tan(72°) = 
x = 
x = 3.899
x ≈ 3.9
3). By using sine rule in ΔKNM,
tan(x°) = 
tan(x) = 
x = 
x = 19.03
x ≈ 19.0°
4). By applying cosine ratio in ΔJKF,
tan(70°) =
tan(70) = 
x = 
x = 21.838
x ≈ 21.8
Answer:
The PV of an ordinary annuity with 10 payments of $2,700 if the appropriate interest rate is 5.5% is $20,352.
Step-by-step explanation:
P = PMT [(1 - (1 / (1 + r)
)) / r]
= 2,700 [(1 - (1 / (1 + 0.055)
)) / 0.05]
= 2,700 [(1 - (1 / (1 + 0.055))) / 0.05]
= 2,700 [(1 - (1 / (1.708)) / 0.05]
= 2,700 [(1 - 0.58)) / 0.05]
= 2,700 [(0.41457) / 0.05]
= 2,700(7.53)
=$ 20,352
Answer:
not sure for the 1st one but pretty sure 2nd one is B
Step-by-step explanation:
C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
