Find (f/g) (x) for the functions provided: ƒ(x) = x3 − 27, g(x) = 3x − 9

AnnZ [28]

Answer:

$(\frac{f}{g})(x)=\frac{1}{3}(x^2+3x+9)$

Step-by-step explanation:

We have been given that

$f(x)=x^3-27,g(x)=3x-9$

We can use the formula for difference of cubes to simplify the function f(x)

difference of cubes - $a^3-b^3=(a-b)(a^2+ab+b^2)$

$f(x)=x^3-27\\\\=x^3-3^3\\\\=(x-3)(x^2+3x+9)$

And g(x) can be written as

$g(x)=3x-9\\=3(x-3)$

Thus, we have

$(\frac{f}{g})(x)=\frac{(x-3)(x^2+3x+9)}{3(x-3}$

On cancelling the common factors, we get

$(\frac{f}{g})(x)=\frac{1}{3}(x^2+3x+9)$

Answer:

Quesnel Lake:Lake Baikal=.31

Quesnel Lake:Great Slave Lake=.82

Step-by-step explanation:

1 foot = .3048 meters

Lake Baikal: 5369 ft. = 1636.4712 m

Great Slave Lake: 2015 ft. = 614.172 m

Quesnel Lake: 506 m

Quesnel Lake:Lake Baikal

$506 \div 1636.472 = .31$

Quesnel Lake:Great Slave Lake

$506 \div 614.172 = .82$

The total area of the United States is 3.79 million square miles, and Texas covers 0.27 million square miles. A meteor falls fro

g100num [7]

The probability that it strikes Texas given that it strikes the US will be "0.071".

Given that,

The total area of US,

P(U) = 3.79 million square miles

Area covered be Taxes,

P(T) = 0.27 million square miles

According to the Baye's theorem,

→ $P(\frac{T}{U} ) = \frac{P(T)\times P(\frac{U}{T} )}{P(U)}$

By substituting the values, we get

→ $\frac{P(T)}{P(U)} = \frac{0.27}{3.79}$

→ $=0.071$

Thus the above answer is correct.
