Reduced by half = 200cm/50 seconds.
20000/50 = 400.
200 x 400 = 80,000cm
X = 5, that’s the answer to question 12
31 is the answer because you would do 5 x 3 an that's 15 and if it's squared u technically add 15 a second time
Answer:
84
Step-by-step explanation:
To find the range, find the difference between the largest value and the smallest value.
544 - 460 = 84
Answer:

Step-by-step explanation:
We need at least two points to write the equation of a straight line.
The recursive formula that Elijah wrote is:


When we substitute n=0, we get:



The points (0,30) and (1,37) lies on this line.
The equation of this line is of the form:

where b =30 is the y-intercept and m=7 is the slope.
We plug in these values to get:

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.
You could also use the two points to find the slope:
