Answer:
29/4 or 7 1/4 cups of sugar and cinnamon
Step-by-step explanation:
Answer:187.5 inches.
Step-by-step explanation:
25 / 2 = x / 15
25 = 2x / 15
15(25) = 2x
375 = 2x
187.5 = x
The actual car is 187.5 inches.
Answer:
cos3x+tan3x=0
⟹cos3x=−tan3x
⟹cos3x=−sin3xcos3x
⟹cos23x=−sin3x
⟹1−sin23x=−sin3x
⟹sin23x−sin3x−1=0
This is a quadratic equation in sin3x.
sin3x=−(−1)±(−1)2−4×1×(−1)−−−−−−−−−−−−−−−−−√2×1
sin3x=1±5–√2
If x takes real values, the upper sign must be rejected.
sin3x=1−5–√2
⟹3x=nπ+(−1)nsin−11−5–√2
⟹x=13[nπ+(−1)nsin−11−5–√2]
