e. False
Step-by-step explanation:
The matrix with orthonormal column must be in square for that it forms orthogonal matrix. Every orthonormal set of non zero vector is linearly independent. This statement is correct because there is linear combination of non zero vectors.
Answer:
115 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so if x is the angle you're trying to have you get:

Answer:

Answer:
Rate = 91 km/hr
Step-by-step explanation:
In this question, Rate = Speed
Speed (s) = Distance (d) / time (t)
Distance = 600 km
Time = 3 hrs for both cars
Speed for car A = x
Speed for car B = (18+x)
Distance traveled for car A = x* 3
Distance traveled for car B = (18+x)* 3
Remember that the total distance traveled = 600 km
3x + 3*(18+x) = 600
3x + 54 + 3x = 600
6x = 600 - 54 = 546
x = 546/6 = 91
Speed of the slower car is 91 km/hr.
