ohaa [14]

Answer:

d = 20.6 miles

Step-by-step explanation:

Given that,

Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west.

It is required to find the distance between two representatives. It it is d. It can be calculated as the resultant if two values as follows :

$d=\sqrt{20^2+5^2} \\\\=20.61\ mi$

So, the sales representative are 20.6 miles apart. Hence, the correct option is (c).

Solve for x: log(3) + 2 log(x) = log(27)

Rom4ik [11]

Answer:

The solution is x = 3

Step-by-step explanation:

Hi there!

First, let´s write the equation:

log(3) + 2 log(x) = log(27)

Substract log(3) from both sides of the equation

2 log(x) = log(27) - log(3)

Apply logarithm property: log(a) -log(b) = log(a/b)

2 log(x) = log(27/3)

2 log(x) = log(9)

Apply logarithm property: log(xᵃ) = a log(x)

log(x²) = log(9)

Apply logarithm equality rule: if log(a) = log(b) then a = b

x² = 9

Apply square root to both sides of the equation

x = 3

The solution is x = 3

Have a nice day!
