Answer:
Correct answer: y- intercept is 200 for time x = 0 sec
y = 200 · (3/2)ˣ
The population after x = 10 minutes is: y = 11,533
Step-by-step explanation:
We see from the diagram that the initial bacterial count is 200 which is y-intercept
The formula for an exponential function is:
y = 200· aˣ
to find the basis a we read the second point (1, 300)
300 = 200 · a¹ => a = 300/200 = 3/2
the exact formula is
y = 200 · (3/2)ˣ
we verify the accuracy of the formula using the third point (2, 450)
450 = 200 · (3/2)² => 450 = 200 · 9/4 => 450 = 50 · 9 => 450 = 450
The population after x = 10 minutes is:
y = 200 · (3/2)¹⁰ = 200 · 57.665 = 11,533
y = 11,533

Answer: 56-(7+5)
Step-by-step explanation:
You can find the amount of muffins left over by adding up the amount of muffins that were eaten and subtracting them from the original amount of blueberry muffins, so the answer is 56-(7+5).
(7+5 is in parentheses because if not, you would have 56-7+5 and get 54).
