Answer:
D) 300 seconds
Step-by-step explanation:
if the river is traveling 1 m/s and Britney is traveling 2 m/s, then half of her speed would be canceled out, resulting in her only traveling 1 m/s taking her 300 seconds or 5 minutes to complete the trip.
18 because 6=22. 12=44. 18=66
Answer:
I believe it's 0.540717
Step-by-step explanation:
3(sin(2))x+(cos(2))(x)=5/4
Simplify: 2.311745x=5/4
Divide: 2.311745x/2.311735=5/4/2.311745
x=0.540717
Answer:
h=20
Step-by-step explanation:
h=3 (V/lw)
h= 3 (960/12*12)
Answer:
‹A = 141°
‹B = 28°
‹C = 11°
*These angles are rounded to the nearest whole*
Step-by-step explanation:
Because you are only given sides you can find an individual angle measures with the inverse law of cosines.
Remember the side opposite of the angle corresponds to that angle.
a² = b² + c² - 2bc cos(A) →
A = cos⁻¹ (a² - b² - c² / -2bc)
b² = a² + c² - 2ac cos(B) →
B = cos⁻¹ (b² - a² - c² / -2ac)
c² = a² + b² - 2ab cos(C) →
C = cos⁻¹ (c² - a² - b² / -2ab)
