Create a sequence with a pattern rule of "add ." Sequence terms Create a sequence with a pattern rule of "multiply by ." Sequenc
Anuta_ua [19.1K]

Answer:

Firstly, to create a sequence we need our natural numbers which will stand for our n and the pattern created will be f(n). where n = 1, 2, 3, 4, . . .

1. If we have f(n) = n + 1, then our sequence would be 2, 4, 5, 6, . . .  with a pattern of adding 1 to our n.

2. If we have f(n) = n x 2, then our sequence would be 1, 4, 6, 8, . . .  with a pattern of multiplying 2 by our n.

3.  If we have f(n) = n + 2 when n is odd and n - 1 when even, then we have 3, 1, 5, 3, . . . as our sequence following the add subtraction pattern.

4. if we have f(n) = n x 2 when n is odd and n/1 when n is even, then we have 2, 4, 10, 6, . . .

Answer:

Answer:

C. The balloon starts at a height of 500 ft  and rises at a rate of 150 ft.

Step-by-step explanation:

We have been given a graph which represents the height of the balloon over time.

We can see from our graph that y-intercept, which represents the height of the balloon (in thousand feet) at time equals zero, is 0.5. To find the correct y-intercept we will multiply 0.5 by 1000 as height of the balloon is given in thousand feet.

Therefore, y-intercept represents that the balloon starts at a height of 500 feet.  

Now let us find slope of our given line using slope formula.

is vertical change or rise.

is horizontal change or run.

Upon substituting given values in above formula we will get,

Now let us multiply 0.15 by 1000 as height of balloon is given in thousand feet.

Therefore, slope of our line is 150 which means that height of balloon is increasing 150 feet per second or balloon is rising at a rate of 150 feet per second.

Upon looking at our given options we can see that option C is the correct choice.

Step-by-step explanation:

The slope is (change in y)/(change in x). Taking (0, 0.5) and (10, 2) since the x axis is horizontal and the y axis vertical, we get the slope to be (2-0.5)/(10-0)=

1.5/10=3/20=0.15. Since it's based off of 1000 feet, we multiply 0.15 by 1000 to get 150 as the rate of change for every x value. In addition, since we start at 0.5, 1000*0.5=500 and we therefore start at 500 ft. Using the information we have, we therefore have C as our answer
