Answer:

B

Step-by-step explanation

This is because the 'principal square root' means the positive square root of a certain number, and so √16 = 4 × 4, making 4 the answer. This has a certain term for it as √16 could equal -4 also (-4 × -4 = 16).

Luda [366]

Apnswer:

p = 1

q = -2

Step-by-step explanation:

5p - 2q = 9   eqn 1

If vector v has an initial point at P1 and a terminal point at P2, write v as multiples of the basis vectors That is, write v in
pantera1 [17]

Answer:

v=9i+3j

Step-by-step explanation:

The given vector, v has initial point at P1 = (−5, −2) and terminal point at P2 = (4, 1).

The vector v is found by subtraction the initial point from the terminal point.

v=<4,1>-<-5,-2>

v=<4--5,1--2>

v=<9,3>

We write v as multiples of the basis vectors to obtain:

v=9i+3j
