Answer:
Step-by-step explanation:
AB = B - A = (36, -45) - (31,-33) = (36 -31, -45-(-33))
AB = (5, -12)

The magnitude of a vector is the root of the sum of the squares of its components.
|AB| = √(5² +(-12)²) = √(25 +144) = √169
|AB| = 13
Answer:
387 km
Step-by-step explanation:
The length of AC, b can be obtained using the cosine rule ; using the cosine relation:
b² = a² + c² - 2ac CosB
b² = 250² + 185² - 2(250*185) Cos125
b² = 62500 + 34225 - 92500 * −0.573576
b² = 96725 + 53055.820
b² = 149780.82
b = sqrt(149780.82)
b = 387.01527
b = 387 km (nearest whole number)
The answer is 9 just reciprocate the 1/3 and the multiply the 9 by 3
11.25= 11 25/100 and you simplified it and you get 11 1/4!
The answer is x = 4/3 (solved for x)
