The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.
1 hour = 60 minutes
5 x 60 = 300
300 + 45 = 345
391 miles/345 min = 1.13 miles per min
1.13 x (60 min/1 mile) = 67.8 miles per hour
Ashley drove ~67.8 miles per hour
hope this helps
Answer:
C) 2(4x² + 5x - 4) is your answer
Step-by-step explanation:
Factor out common factors from all terms.
Note the factors for 8 & 10:
8: 1, 2, 4, 8
10: 1, 2, 5, 10
2 is the largest common factor, and so factor out 2
8x² + 10x - 8 = 2(4x² + 5x - 4)
C) 2(4x² + 5x - 4) is your answer
Note that you cannot factor out anymore common factor numbers or variables.
