Answer:

Decay

Step-by-step explanation:

Any "r" value between 0 and 1 indicates an exponential function in decay. The "r" value is the one in the parentheses and raised to the exponent. In this case, the value is 0.91. This number falls within the "r" value boundaries of a decaying exponential function.

Which expression is equivalent to 144 superscript three-halves?

IrinaK [193]

Using the law of indices the equivalent expression of $144^{\frac{3}{2} }$ is 1728

<h3>How to find equivalent expression?</h3>

The equivalent expression of $144^{\frac{3}{2} }$ can be express as follows:

Using the law of indices,

$(a^{b} )^{c} = a^{bc}$

Applying this laws,

$144^{\frac{3}{2} }=(12^{2} )^{\frac{3}{2} }$

Hence,

$144^{\frac{3}{2} }=(12^{2} )^{\frac{3}{2} } = 12^{3}$

Finally,

12³ = 1728

Answer:

option 3) EF= -7 FG= -7

Step-by-step explanation

X= 1/2

EF= 2X-8

= 2 X 1/2 -8

=1 - 8

EF = -7

FG= 4X -9

= 4X 1/2

2 - 9

FG = -7

A plane traveled from California and back. It took one hour longer on the way out than it did on the way back. The plane's avera

padilas [110]

Answer:

Option D is the correct answer.

Step-by-step explanation:

Let x be the one way distance and t be the time out.

Time taken for back = t-1

We have plane's average speed out was 300 mph and average speed on the way back was 350 mph.

That is

$\frac{x}{300}=t\texttt{ and }\frac{x}{350}=t-1$

Dividing both equations

$\frac{\frac{x}{300}}{\frac{x}{350}}=\frac{t}{t-1}\\\\350t-350=300t\\\\t=7\texttt{ hours}$

Time taken for back = t-1 = 7-1 = 6 hours.

Total time taken = 7 + 6 = 13 hours

Option D is the correct answer.
