<h3> Explain:  </h3>

A quadratic relationship is characterized by constant second differences.

<em><u>Pattern A </u></em>

Sequence: 0, 2, 4, 6

First Differences: 2, 2, 2 . . . . constant indicates a 1st-degree (linear, arithmetic) sequence

__________________________________________________________

<em><u>Pattern B</u></em>

Sequence: 1, 2, 5, 10

First Differences: 1, 3, 5

Second Differences: 2, 2 . . . . constant indicates a 2nd-degree (quadratic) sequence

__________________________________________________________

<em><u>Pattern C</u></em>

Sequence: 1, 3, 9, 27

First Differences: 2, 6, 18

Second Differences: 4, 12 . . . . each set of differences has a common ratio, indicating an exponential (geometric) sequence

Answer:

Therefore, the four intervals are

(1)    6 - 6.59

(2)   7 - 7.59      

(3)    8 - 8.59      

(4)    9 - 9.59

The four frequencies are

(1)   4

(2)   3

(3)   1    

(4)  6

Step-by-step explanation:

From the data, we have

                     Interval                                                       Frequency

1st                 6 - 6.59                                                        4

2nd               7 - 7.59                                                        3

3rd                8 - 8.59                                                        1

4th                 9 - 9.59                                                       6

Therefore, the four intervals are

(1)    6 - 6.59

(2)   7 - 7.59      

(3)    8 - 8.59      

(4)    9 - 9.59

The four frequencies are

The equation Y equals 4/10 X describes the number of kilometers y that a van travels in x minutes. What is the constant speed of
Mekhanik [1.2K]

Answer:

\frac{4}{10}=0.4 kilometers per hour.

Step-by-step explanation:

We have been given an y=\frac{4}{10}x, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.

We can see that van travel \frac{4}{10}x kilometers in x hours. To find the constant speed of van, we will substitute x=1 in our given equation as:

y=\frac{4}{10}(1)

y=\frac{4}{10}

Since van travels \frac{4}{10} kilometers in one hour, therefore, constant speed of van is \frac{4}{10} kilometer per hour or 0.4 kilometers per hour.
