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).

If (a^x a ^y) - a^z = a^m then express m in terms of x, y and z.​
omeli [17]

Answer:

m = x+y-z

Step-by-step explanation:

Given the expression.

(a^x a ^y) ÷ a^z = a^m

We are to express m in terms of x, y and z.

Using the multiplicative law of indices, the expression becomes:

a^{x+y} ÷ a^z = a^m

Applying the division rule in indices

a^{x+y} ÷ a^z = a^{x+y-z}

The equation becomes

a^{x+y-z} = a^m

Cancel out the base and equate the powers as shown:

x+y-z = m

Hence the expression of m in terms of x, y and z is m = x+y-z

Using the graph to the right, write the ratio in simplest form. BD/AD
Romashka [77]

Answer:

\frac{BD}{AD} = \frac{5}{7}

Step-by-step explanation:

Coordinate of B = 1

Coordinate of D = 6

Coordinate of A = -1

BD = |1 - 6| = 5 units

AD = |-1 - 6| = |-7| = 7 units

\frac{BD}{AD}

Plug in the values

\frac{BD}{AD} = \frac{5}{7}

A restaurant offers 77 possible​ appetizers, 1515 possible main​ courses, and 99 possible desserts. how many different meals are
JulsSmile [24]
First you need to multiply all the numbers to get 11548845 and then for example you need to do this (77*1515)+(77*99)+(99*1515) = 274263 to get and then you need you need to add 77,1515,99 to get 1691 and then you add 11548845, 274263, and 1691 to get 11824799 and that is the total number of possible outcomes of meals that you can get.
