Researches notice a grey whale cruising at a depth of 233 feet below sea level. It rises 73 feet and then comes up another 40 fe

musickatia [10]

Answer:

The whale is at a depth 120 feet below the sea level.

Step-by-step explanation:

A grey whale is cruising at a depth of 233 feet below sea level. The depth below the sea level has the negative position, thus the initial position of the whale is -233.

It rises 73 feet, the position of the whale becomes 73 feet higher. This means we should add 73.

Then it comes up another 40 feet, so we need to add 40.

Mathematically,

$-233+73+40=-160+40=-120$

The whale is at a depth 120 feet below the sea level.

Complete the table by providing justification for each step of the proof

exis [7]

4(x² - 2) = 28

1. Distribute the 4
4x² - 8 = -28

2. Plug in 3 and -3
4(3)² - 8 = 28
4(-3)² - 8 = 28

3. Square 3 and -3
4(9) - 8 = 28
4(9) - 8 = 28

28 = 28

The reason both answers are the same is because whenever you put a negative number to an even power, the result becomes positive because any negative multiplied by a negative number is always positive.
28 = 28

Condensing Logarithmic Expression In Exercise,use the properties of logarithms to rewrite the expression as the logarithm of a s

nevsk [136]

Answer:

$[ln \frac{x(x^2 + 1)}{(x + 1)}]^\frac{3}{2}$

Step-by-step explanation:

$\frac{3}{2} [ln x(x^2 + 1) - ln(x + 1)]$

ln(m/n)= lnm - ln(n)

$\frac{3}{2}[ln x(x^2 + 1) - ln(x + 1)]$

$\frac{3}{2}[ln \frac{x(x^2 + 1)}{(x + 1)}]$

3/2 is before ln. so we move the fraction 3/2 to the exponent

as per log property we move the fraction to the exponent

$[ln \frac{x(x^2 + 1)}{(x + 1)}]^\frac{3}{2}$
