Answer:

C. \huge\frac{1}{3x {y}^{2}  {z}^{4}}

Step-by-step explanation:

(9 {x}^{2}  {y}^{4}  {z}^{8} )^{  - \frac{1}{2} }  \\   \\  = ( {3}^{2}  {x}^{2}  {y}^{4}  {z}^{8} )^{  - \frac{1}{2} }  \\  \\  =  \frac{1}{( {3}^{2}  {x}^{2}  {y}^{4}  {z}^{8} )^{ \frac{1}{2} }}  \\  \\  =  \frac{1}{(3x {y}^{2}  {z}^{4})^{2 \times  \frac{1}{2} }  }  \\  \\  =  \frac{1}{3x {y}^{2}  {z}^{4}} \\  \\  \red{ \bold{ \therefore \: (9 {x}^{2}  {y}^{4}  {z}^{8} )^{  - \frac{1}{2} } =  \frac{1}{3x {y}^{2}  {z}^{4}} }}\\

Dmitrij [34]

Options are:

Impossible

Certain

Likely

Unlikely

Answer:

Unlikely

Step-by-step explanation:

A ferry is a large ship that carries passengers and loads on water.

A ferry rarely sinks. Infact, the United States experience very low cases of shipwreck yearly. According to wikipedia in 2018, not more than 200 shipwrecks happened all over the world compared to a great number of operations that year.

Therefore, based on statistics, the ferry is unlikely to sink.

A scuba diver returning to the surface swims to move up quickly, then waits a few meters below the surface to avoid pressure iss
Juliette [100K]

Given:

The function f represents the diver's distance from sea level over time, in seconds.

f(x)=\begin{cases}3x+1 & \text{ if } -9

To find:

The correct statement for the domain.

Solution:

Domain is the set of input values for which the function is defined.

Here, x values are the input values and they represent time intervals on which the function is defined

Here, the possible intervals for x are -9.

Domain=(-9,-2]\cup (-2,1]\cup (1,7)

Domain=(-9,7)

Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.
