Answer:

a. 0.76,-0.76

Step-by-step explanation:

The given equation is;

-8=-3-6\sqrt[3]{x^2}

Add 3 to both sides of the equation to get;

-8+3=-3+3-6\sqrt[3]{x^2}

\Rightarrow -5=-6\sqrt[3]{x^2}

Divide both sides by -6.

\Rightarrow \frac{-5}{-6}=\sqrt[3]{x^2}

\Rightarrow \frac{5}{6}=\sqrt[3]{x^2}

Cube both sides of the equation;

\Rightarrow (\frac{5}{6})^3=x^2

\Rightarrow \frac{125}{216}=x^2

Take square root of both sides

\pm \sqrt{\frac{125}{216}}=x

\pm 0.76=x

\therefore x=0.76,-0.76

Answer:

Step-by-step explanation:

First, add 3 to both sides:

-5 = -6∛(x²)

Next, divide both sides by -6, to isolate ∛(x²):

5/6 = ∛(x²)

Eliminate the radical by cubing both sides:

5³

---- = x²

6³

Finally, take the square root of both sides.  This will isolate x.  There will be two roots:  one +, the other -.

x = ±√(5³/6³)

This simplifies to:  ± (5/6)∛(5/6).

What is the value of x in this proportion?
astra-53 [7]

Answer:

  (a)  x=−20 1/2

Step-by-step explanation:

Multiply by the product of the denominators and solve the resulting linear equation in the usual way.

  \dfrac{2}{7}=\dfrac{-5}{x+3}\\\\2(x+3)=-5(7)\qquad\text{multiply by $7(x+3)$}\\\\2x+6=-35\qquad\text{simplify}\\\\2x=-41\qquad\text{subtract 6}\\\\\boxed{x=-20\dfrac{1}{2}}\qquad\text{divide by 2}

Human population numbers are in constant flux. Suppose a country has a population of 20 million people at the start of one year
Sati [7]
  • Birth=+600000
  • Death=-350000
  • Immigrants=+100000
  • emigrants=-5000

. Population Change:-

\\ \sf\longmapsto 600000-350000+100000-5000=+350000

Population:-

\\ \sf\longmapsto 2000000+350000=2350000

A submarine is at -125 feet in the ocean. The submarine makes 3 dives of 50 feet each. At what level is the submarine after thre
iren2701 [21]
Each dive goes further down, so it represents -50 ft (not positive which would represnt going up).

y= -125-50x

We know that there are 3 dives so plug that in for x
y= -125-50(3)
y= -125-150
y= -275

Final answer: -275 ft
