Answer:
I think you would have to add 12.5 to the 5
Step-by-step explanation:
Answer:
x = 41.81°, 138.19°, 210°, 330°
Explanation:
3cos(2x) + sin(x) = 1
subtract one from both sides
→ 3cos(2x) + sin(x) − 1 = 0
rewrite using trigonometry identities
→ 2 + sin(x) − 6sin²(x) = 0
solve x by substitution
f(x) = 2 + sin(x) − 6sin²(x)
= 2 + 4sin(x) - 3sin(x) − 6sin²(x)
= −2sinx(3sinx −2) − (3sinx−2)
= (3sinx −2)(−2sinx−1)
= −(3sinx −2)(2sinx+1)
f(x) = 2 + sin(x) − 6sin²(x) = 0
= −(3sinx −2)(2sinx+1) = 0
(3sinx −2) = 0 (2sinx+1) = 0
→sinx = 2/3 →sinx = −1/2
x = 41.81°, 138.19° x = 210°, 330°

The area of Neil's rooms total
... (10 ft)×(10 ft) + (14 ft)×(14 ft) = 100 ft² +196 ft²
... = 296 ft²
Since Neil will save $1 per square foot by waiting on the sale, he will save
... (296 ft²)×($1/ft²) = $296
Answer:
Distance between Exeter and the point where flat tire occurred was 1.875 miles.
Step-by-step explanation:
Let the distance of Exeter and the point where bike developed the flat tire was = x miles
Then time taken to reach that point with speed 15 mi per hour = 
= 
hours
Devon comes back with a speed of 3 miles per hour then time taken to come back = 
hours
Total time for the entire episode = 48 minutes or 
hours
Therefore, 
x = 
x = 
miles
x = 1.875 miles
Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.
