The inverse of F(X) is a function.

For something to be a function, a vertical line must not intersect the graph more than once. Since, the horizontal line doesn't intersect the F(X) graph twice, this means that the vertical line won't intersect with the inverse of the graph

The first four sequences are shown below 9,5,1,-3 which of the following functions best defines this sequence
Anvisha [2.4K]

Answer:

Arithmetic sequence.

Step-by-step explanation:

We have been given 9,5,1 and -3

We need to check what kind of sequence is this.

d=a_2-a_1

d is common difference we will check difference of consecutive terms.

5-9=-4

1-5=-4

-3-1=-4

We can see the difference between all the terms are same that is -4

So, this is an arithmetic sequence.

Arithmetic sequence is the sequence in which the difference between consecutive terms are same.

Rajan needs 1 liter of 15% hydrochloric acid solution for an experiment. He checks his storage cabinet, but he only has a 5-lite
yarga [219]

Answer:

<em>Rajan must use </em><em>0.75</em><em> liters of 5% hydrochloric acid solution and </em><em>0.25</em><em> liters of 45% hydrochloric acid solution.</em>

Step-by-step explanation:

Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.

As Rajan need total of 1 liter of solution, so

x+y=1

i.e x=1-y --------------------1

As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so

0.05x+0.45y=1\times 0.15

i.e 5x+45y=15 -------------2

Putting value of x from equation 1 in equation 2,

\Rightarrow 5(1-y)+45y=15

\Rightarrow 5-5y+45y=15

\Rightarrow 5+40y=15

\Rightarrow 40y=15-5=10

\Rightarrow y=0.25

Putting the value of y in equation 1,

x=1-0.25=0.75

Therefore, Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.

MariettaO [177]

Answer:

The mean number of customers that will arrive in a five-minute period is 2.

Step-by-step explanation:

a. What is the mean or expected number of customers that will arrive in a five-minute period

For one minute, the mean is of 0.4 customers.

So, using proportions, for 5 minutes, the mean is of 5*0.4 = 2 customers.

The mean number of customers that will arrive in a five-minute period is 2.
