Answer: Domain is All Real Numbers, x = {1, -1}
<u>Step-by-step explanation:</u>
log₄² (1 + x²) = 0.25 restriction: 1 + x² ≥ 0 ⇒ x² ≥ -1 ⇒ x = ARN
log₄ (1 + x²) = 0.05
(1 + x²) = 4¹⁾²
1 + x² = 2
x² = 1
x = √1
x = +/- 1
This can be solve by 3 variable equation
let x be the money of luke
y money of rachel
z money of daniel
first equation
x = y + 21
second equation
x = z + 48
third equation
x + y + z = 168
solving simultaneously
x =79
y = 58
z = 31

ANSWER
EXPLANATION
We use the sine rule to obtain,
We multiply both sides by 4 to obtain,
We take the inverse sine of both sides to get,
to the nearest tenth.
