Ответ:
Shania types 30 words in 1 minute. --> (1, 30)
Shania types 120 words in 4 minutes. --> (4,120)
Shania types 150 words in 5 minutes. ---> (5, 150)
Step-by-step explanation:
In the given graph, At x-axis we have Time (minutes) which is an independent variable. On the other hand, at y-axis we have Words type which is dependent varaible.
Point on graph is written in the form (x,y)
So, points corresponding to
Shania types 30 words in 1 minute. --> (1, 30) [here x= 1 and y=30]
Shania types 120 words in 4 minutes. --> (4,120) [here x=4 and y=120]
Shania types 150 words in 5 minutes. ---> (5, 150)[here x= 5 and y=150]
Ответ:
it appears that the number of villagers in brian's game for 0 towns is 8.
for 1 town, it is 8·1.17
for 2 towns, it is 8·1.17·1.17 = 8·1.17²
for 3 towns, it is 8·1.17·1.17·1.17 = 8·1.17³
apparently, for n towns, the number of villagers in brian's game is 8·1.17ⁿ. this expression can be put into an equation that expresses the number of villagers (v) as a function of n:
v(n) = 8·1.17ⁿ . . . equation to predict villagers for n towns
for 16 towns, we can substitute the value 16 for n to find the number of villagers.
v(16) = 8·1.17¹⁶ ≈ 99 villagers
