Describe a theme park ride that has a constant speed but changing velocity?

2 answers:

7 0

The only difference between speed and velocity is that velocity also includes direction, so if the speed is the same but the velocity is changing, that means that the direction is changing on the ride, but the speed is staying the same.

A Ferris wheel is a good example of a ride that would change velocity but not speed. Because it moves around in circles, it changes direction but the speed remains the same.

Write down the first 5 terms of n squared + n

Alex73 [517]

Answer:

2, 6, 12, 20, 30

Step-by-step explanation:

To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression

n = 1 → 1² + 1 = 1 + 1 = 2

n = 2 → 2² + 2 = 4 + 2 = 6

n = 3 → 3² + 3 = 9 + 3 = 12

n = 4 → 4² + 4 = 16 + 4 = 20

n = 5 → 5² + 5 = 25 + 5 = 30

Make a frequency distribution and find the relative frequencies for the following number set. Round the relative frequency to th

Pani-rosa [81]

Solution: We have to find the Frequency and Relative frequency of the given data:

Frequency is the number of times a number occurs.

Relative Frequency is the number of times a number occurs divided by the total number of items.

Therefore, the frequency and relative frequency are calculated as below:

Number Frequency Relative Frequency

20 1 $\frac{1}{31} \times 100 =3.2\%$

21 4 $\frac{4}{31} \times 100 =12.9\%$

22 2 $\frac{2}{31} \times 100 =6.5\%$

23 4 $\frac{4}{31} \times 100 =12.9\%$

24 3 $\frac{3}{31} \times 100 =9.7\%$

25 2 $\frac{2}{31} \times 100 =6.5\%$

26 3 $\frac{3}{31} \times 100 =9.7\%$

27 5 $\frac{5}{31} \times 100 =16.1\%$

28 3 $\frac{3}{31} \times 100 =9.7\%$

29 4 $\frac{4}{31} \times 100 =12.9\%$

I think the equation should be

$n=75\cdot3^t$

where 3 is the common ratio of the exponential function

so the answer is C.
