The map shows the length (in miles) of shoreline along the Gulf of Mexica for each state that borders the body of water. What is

Jet001 [13]

Answer:

TX: 0.23

LA: 0.24

MS: 0.03

AL: 0.03

FL: 0.47

Step-by-step explanation:

In the figure attached, the map is shown.

Total length of the shoreline: 367 + 397 + 44 + 53 + 770 = 1631 miles

probability of the ship landing in Texas: 367/1631 = 0.23

probability of the ship landing in Louisiana: 397/1631 = 0.24

probability of the ship landing in Mississippi: 44/1631 = 0.03

probability of the ship landing in Alabama: 53/1631 = 0.03

probability of the ship landing in Florida: 770/1631 = 0.47

Explain why f(x) = x^2-x-6/x^2-9 is not continuous at x = 3.

iren [92.7K]

Answer:

See Explanation

Step-by-step explanation:

Given

$f(x) = \frac{x^2 - x -6}{x^2 - 9}$

Required

Why is the function not continuous at x = 3

First substitute 3 for x at the denominator

$f(x) = \frac{x^2 - x -6}{x^2 - 9}$

Factorize the numerator and the denominator

$f(x) = \frac{x^2 - 3x+2x -6}{x^2 - 3^2}$

$f(x) = \frac{x(x - 3)+2(x -3)}{(x - 3)(x+3)}$

$f(x) = \frac{(x+2)(x - 3)}{(x - 3)(x+3)}$

Divide the numerator and denominator by (x - 3)

$f(x) = \frac{x+2}{x+3}$

Substitute 3 for x

$f(3) = \frac{3+2}{3+3}$

$f(3) = \frac{5}{6}$

Because $f(x) = \frac{x^2 - x -6}{x^2 - 9}$ is defined when x = 3;

Then the function is continuous
