B (t) = 50 (1.4) ^ t
What is the y-intercept of the function?
The intersection with the y-axis of the function you find when x = 0.
In this case we have:
For t = 0:
B (0) = 50 (1.4) ^ 0
B (0) = 50 * (1)
B (0) = 50
Answer:
the y-intercept of the function is:
B (0) = 50
What does this mean in the context of the problem?
You must place the complete statement to answer exactly.
However, in any problem of exponential type, it means the initial quantity of something.
If we refer to the increase in population over time, then the intersection with the y-axis is the initial population.
9C + 2A = $50
10C+ 3A = $61
3(9C + 2A = $50)
-2(10C+ 3A = $61)
27C + 6A = 150
-20C + -6A = -122
-------------------------
7C = 28
7C/7 = 28/7
C = 4
9(4) +2A = $50
36 + 2A =$50
36-36 + 2A= $50-36
2A = 14
2A/2 = 14/2
A = 7
CHECK
9(4) + 2(7) = $50
36 + 14 = $50
$50 = $50
10(4)+ 3(7) = $61
40 + 21 =$61
$61 = $61

Hello! It's hard to understand your tables, so I could help you in a general way. Remember you have to write clear questions in order to get good and exact answers.
When we say that varies directly as or is directly proportional to , we say that can be written in terms of as the following form:
Where is the constant of variation or the constant of proportionality.
So this is a line that passes through the origin. So we can establish a table as follows:
Answer:
(a) $ 1.60
(b) $ 0.96
Step-by-step explanation:
(a) Cost of printing 2000 posters = Cost of first thousand + cost of second thousand = 1500 + 1200 = 2700
Total cost = 2700 + 500 = 3200
Average Total Cost = Total cost/Number of posters = 3200/2000 = $ 1.60
(b) Cost of printing 10000 posters = Cost of first thousand + cost of second thousand + (800 × Number of additional thousands)
Number of additional thousands = (10000 - 1000 - 1000)/1000 = 8000/1000 = 8
Cost of printing 2000 posters = 1500 + 1200 + (800 × 8) = 2700 + 6400 = 9100
Total cost = 9100 + 500 = 9600
Average Total Cost = Total cost/Number of posters = 9600/10000 = $ 0.96
Answer:
76 cm cubed
Step-by-step explanation:
2 x 2 x 4 = 16 cm cubed
3 x 4 x 5 = 60 cm cubed
