Answer:
See explanation below
Step-by-step explanation:
The best explanation is noticing that in order to get from the point R (12, 1) to the point Q (7, 4) we move 5 units to the left and 3 units up. And to go from point Q (7, 4) to point P (2, 7) we do exactly the same: move 5 units to the left and 3 units up. That means that these points are all connected via the same rate of change: - 3/5, which is in fact the slope of the line the three points belong to.
Answer: D) 
Step-by-step explanation:
From the given table we can see that this is not representing a linear function as the rate of change is not constant.
So it can be exponential growth function
, where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.
Now here at n=1 , f(n)=8
Therefore, A=8
Now, for n=2

By substitute the values of A and b in the above equation, we get the equation 
Therefore, the function best shows the relationship between n and f(n) is
, where n is the number of weeks.
Answer:
100 meters per minute
Step-by-step explanation:
Find his average speed by dividing the distance he walked by the number of minutes it took him:
500/5
= 100
So, his average speed was 100 meters per minute
Answer:
° 3/2 × 4/15
Step-by-step explanation:
for checking a division problem use the product and one of the fractions to multiply. if the answer matches the other fraction then your division is correct.
Answer:
5.236 units
Step-by-step explanation:
The relation between r, θ and arc length ( l ) is,
l = rθ
l = 1 * 5π / 3
( The value of π = 3.14 approximately )
5π = 5 x 3.14 = 15.7
l = 1 * 5π / 3
= 5π / 3
= 15.7/3
l = 5.236 units
Note : -
Arc length is denoted by " l ".
