a_{6} = 33

the n th term of an arithmetic sequence is

a_{n} = a_{1} + (n - 1 )d, hence

a_{6} = 13 + (5 × 4 ) = 13 + 20 = 33

Which graph represents the function f (x) = StartFraction 2 x minus 1 Over x minus 1 EndFraction?
Lubov Fominskaja [6]

The correct description of the graph:

<em>"One curve opens up and to the right in quadrant 1, and the other curve down and to the left in </em><em>quadrants </em><em>2, 1, and 4."</em>

<h3>Which graph is the graph of the given functions?</h3>

Here we have the function:

f(x) = \frac{2x - 1}{x - 1}

The graph of this function can be seen below:

Then we can see that a curve opens up on quadrant 1, and down on quadrants 2 and 3 (it pass throw quadrant 1 for a little bit).

Then the correct option is:

<em>"One curve opens up and to the right in </em><em>quadrant </em><em>1, and the other curve down and to the left in </em><em>quadrants </em><em>2, 1, and 4."</em>

there are some pets in a pet shop. 36% of them are rabbits, 28% of them are dogs and the rest are hamsters. If there are 160 dog
guapka [62]

Answer:

250

Step-by-step explanation:

36% are rabbits, and 28% are dogs.  That means the percent that are hamsters is:

100% − 36% − 28% = 36%

There are 160 dogs and hamsters, which are 28% + 36% = 64% of the pets.  Therefore, we can write and solve a proportion:

160 / 64% = x / 100%

x = 250

There are a total of 250 pets.
