Answer:
- sin(x) = ±(√2)/2
- r.a. = 45°
- x = 45° +k·360°
- x = 135° +k·360°
- x = 225° +k·360°
- x = 315° +k·360°
- x ∈ {135°, 225°, 315°, 405°}
Step-by-step explanation:
Start by solving for sin(x).
4sin(x)² = 2
sin(x)² = 1/2 . . . . divide by 4
sin(x) = ±√(1/2) = ±(√2)/2
Use your knowledge of the sine function to recognize that the reference angle is 45°, and that the angles x will be ...
x = ±45° or 180°±45° with multiples of 360° added
The solutions in the desired range are ...
x ∈ {135°, 225°, 315°, 405°}

Answer:
Assuming Kipp had $129 BEFORE the bank charged an overdraft fee, the answer is negative $8.
Step-by-step explanation:
Kipp started with $129.
He was charged $25 by the bank, thus making his bank account balance: $104.
Kipp uses his debit card to buy clothes, which cost $112.
After the overdraft fee, he had $104.
After purchasing the clothing, he had -$8.
Therefore, Kipp has -$8 in his bank account

Answer:
x = 2
Step-by-step explanation:
1. Divide both sides by 2
2 (x + 3) ÷ 2 = 10 ÷ 2
2. Simplify
x + 3 = 5
3. Subtract 3 from both sides
x + 3 - 3 = 5 - 3
4. Simplify
x = 2
