A tablet data provider offers different plans for data usage. The plan Raul chose has a monthly fee of $29.99 per month for 5 GB

of data with an additional cost of $10 for each gigabyte over 5.

Answer:

The minimum number is 9 GB to make the unlimited cheaper

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- A tablet data provider offers different plans for data usage

- The plan Raul chose has a monthly fee of $29.99 per month for

 5 GB of data with an additional cost of $10 for each gigabyte

 over 5

* <u><em>Assume that he will use </em></u><u><em>n gigabyte per month</em></u>

∵ The monthly fee is $29.99 for 5 GB

∵ The cost per GB after the first 5 GB is $10

∵ The number of GB whose cost is $10 is (n - 5)

∴ His monthly fees = 29.99 + 10 (n - 5) ⇒ current plan

- Raul learns that his data provider is offering an unlimited data

 plan for $59.99 per month

∵ The fees of the unlimited is $59.99 per month

∵ We need the unlimited cheaper than current plane

- Let the current plan greater than the unlimited plan

∴ 29.99 + 10 (n - 5) > 59.99

- Subtract both sides by 29.99

∴ 10 (n - 5) > 30

- Divide both sides by 30

∴ n - 5 > 3

- Add both sides by 5

∴ n > 8

∴ The minimum number is 9 GB to make the unlimited cheaper

The graph of ƒ(x) = -√x is shifted to the right five units. The domain of the function represented by this graph is x ≥&gt;≤&lt;
Mars2501 [29]

Answer:

Domain = [5,∞)

Step-by-step explanation:

Given: f(x)=-\sqrt{x}

We are given that f(x) is shifted right by 5 units.

Rule : f(x)→f(x-b)

The graph f(x) shifted b units right

So, using rule : -\sqrt{x} →   -\sqrt{x-5}

So, g(x)=-\sqrt{x-5}

Now to find domain:

x-5>0

x>5

So, Domain = [5,∞).

Convert 11.42424242 to a rational expression in the form of a/b , where b ≠ 0.
TiliK225 [7]
11.424242
isolate the repeating part
11+0.424242

focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242

subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
x=\frac{42}{99}



so
11.\overline{42}=11 \space\ \frac{42}{99}
