Write a rule for the following functions. I need help fast!
marishachu [46]

Answer:

  20.  y = 3·3^x

  21.  y = (1/3)^x

Step-by-step explanation:

These exponential functions can be written in the form ...

  y = a·b^x

where a is the value of y when x=0, and b is the common ratio between terms that have x different by 1.

__

20. The ratio is 9/3 = 3; the multiplier is 3 (the value of y when x=0), so the function is ...

  y = 3·3^x

__

21. The ratio is (1/3)/1 = 1/3; the multiplier is 1, so the function is ...

  y = (1/3)^x

_____

<em>Alternate solution</em>

Each of these can be written in a more compact form:

  20: y = 3^(x+1)

  21: y = 3^(-x)

On a shelf at a gaming store, there are six Sony Playstations and five Nintendo Wii consoles left. If one gaming system is selec
Sholpan [36]

Answer:

The probability that the system is a Wii console is 0.46

Step-by-step explanation:

Probability expresses the possibility of an occurrence of an event. The probable outcomes for the event is called sample space.

For the given question,

Number of Sony Playstations = 6

Number of Nintendo Wii consoles = 5

Total number of games on the shelve = 11

Probability that the game selected is Wii console implies the possibility of picking one out of the 5 consoles.

pr(the system is a Wii console) = \frac{5}{11}

                                                   = 0.4555

                                                   ≅ 0.46

The probability that the system is a Wii console is 0.46.

Allana used Fraction 3 over 5 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 7 over 10 yard
Delvig [45]

Answer:

Step-by-step explanation:

Divide 1 7/10 by 3/5 to see if the quotient is greater than 2.  If it's not, you can't get 2 scarves out of it.  If it is, then you can get 2 scarves out of it and have whatever the remainder is as left-over.  Before we divide, let's change that 1 7/10 into an improper fraction since it will be easier to work with.

1 7/10 = 17/10

Now we can divide:

\frac{\frac{17}{10} }{\frac{3}{5} }

The rule for dividing fractions is that you bring up the lower fraction and flip it to multiply, so that looks like this:

\frac{17}{10}×\frac{5}{3}

To simplify before we multiply, we can reduce between the 5 and the 10 and have smaller numbers to deal with:

\frac{17}{2}×\frac{1}{3}

The product there is \frac{17}{6}=2\frac{5}{6}

So the answer you want from your choices is

"Yes, because the quotient of Fraction 1 and 7 over 10 [division sign]Fraction 3 over 5 is 2 and 5 over 6", third choice
