Answer:
D
Step-by-step explanation:
Answer:
f(0) = 0
f(-2) = 1
Step-by-step explanation:
f(0) means the value of f when x = 0. The line is the result of equation f for all points shown on the graph. Look for the values at x = 0 and x = -2.
They are (0.0) and (-2,1). This can be written as:
f(0) = 0
f(-2) = 1
See the plants grow in airthemetic progression.
day 1 its is 1 and day 2 it is 2, day 3 it is 4.......
so,
1,2,4,6,8,......
so it take 48 days to fill the pond..
total plants = 48/2(2*1+(48-1)*2)
total plants= 2304
so half the plants is 1152
so,
1152=n/2(2*1+(n-1)2)
n=47
it so 47 days to complete half the pond.
Total length of fabric is: 3 + 3 + 5 = 11 feets
