Temp is explanatory and ice cream sales is the response
Answer:
1/8
Step-by-step explanation:
sin²(π/8) − cos⁴(3π/8)
Use power reduction formulas:
1/2 (1 − cos(2×π/8)) − 1/8 (3 + 4 cos(2×3π/8) + cos(4×3π/8))
Simplify:
1/2 (1 − cos(π/4)) − 1/8 (3 + 4 cos(3π/4) + cos(3π/2))
1/2 (1 − √2/2) − 1/8 (3 + 4 (-√2/2) + 0)
1/2 − √2/4 − 1/8 (3 − 2√2)
1/2 − √2/4 − 3/8 +√2/4
1/2 − 3/8
1/8
36 × 24 = 864 square inches. 864 sq in × $0.05 = $43.20. The green poster cost $43.20
12 × 18 = 216 square inches. 216 sq in × $0.05 = $10.80. The red poster cost $10.80

It would be the first one.
The measure of the intercepted arc (a) is twice the measure of the inscribed angle intercepting it (b or 25°). The measures of the inscribed angles are all the same: b = 25°.
The appropriate choice is D. 25
