Answer:

AB = (5, -12)
|AB| = 13

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

When performing a horizontal analysis on an income statement, the percentage change in any individual item is calculated by div

oksian1 [2.3K]

Answer: C. the base period amount.

Explanation: While implementing a horizontal analysis on a given income statement, we compute a percentage change in any individual item by dividing the dollar amount of change from base to current time period with the base period amount.

i.e. % Change in Individual item = $\frac{Current\ Dollar\ - Base\ Dollar }{Base \ period \ amount}$

Therefore, the correct option in this case is (c)

Answer:

D 7x( x^2y) ^1/3

Step-by-step explanation:

5x (x^2y)^1/3 +2 (x^5y)^1/3

We can simplify the second term

2 (x^5y)^1/3 = 2 (x^3 * x^2y) ^1/3

We know that (a*b) ^c = a^c * b^c

2 (x^3 * x^2y) ^1/3 = 2 (x^3 )^1/3*( x^2y) ^1/3

2*x*( x^2y) ^1/3

Replacing this into the original equation

5x (x^2y)^1/3 +2x( x^2y) ^1/3

The term inside the cube root is the same, so we can add the terms on the outside

(5x+2x) 2x( x^2y) ^1/3

(7x)( x^2y) ^1/3
