Answer:

$\sqrt{12a \: + \: 12b \: - \: 2ab \: + \: 2b {}^{2} }$

Step-by-step explanation:

(a²-b²) / (a+b) = 12

a² - b² = 12(a+b)

(a-b)² + 2ab - 2b² = 12a + 12b

(a-b)² = 12a + 12b - 2ab + 2b²

a - b =

$\sqrt{12a \: + 12b \: - 2ab \: + \: 2b {}^{2} }$

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

an oil spill covers 8 square miles. Measurements show that the area is tripling every 4 hrs. Find an exponential model for the a

Serjik [45]

Answer: The exponential model for the area would be $8(0.75)^t$ .

Step-by-step explanation:

Since we have given that

Initial square miles = 8

It gets tripled in every 4 hours.

So, in every 4 hours, it become 3.

In every 1 hour, it becomes $\dfrac{3}{4}$

So, According to question, an exponential model for the area would be

$Ab^t\\\\=8(\dfrac{3}{4})^t\\\\=8(0.75)^t$

Hence, the exponential model for the area would be $8(0.75)^t$

–0.3 is less than One-fifth

0 is greater than –0.5

Negative three-fifths is equal to –0.6

Number line :

-1 to 0 to 1

-1, - 0.8, - 0.6, - 0.4, - 0.2, 0, 0.2, 0.4, 0.6, 0.8, 1

–1 is less than Negative StartFraction 4 Over 5 EndFraction : - 1 < - 0.8 (true)

–0.3 is less than One-fifth : - 0.3 < 0.2 (true)

0.6 is greater than 1 ( false)

0 is greater than –0.5 (true)

Negative three-fifths is equal to –0.6; - 0.6 = - 0.6 ( true)
