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:” use
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal
Let x be the fluid ounces of milk does Monica use.
As per the statement:
Monica uses 3 tablespoons of milk in her custard recipe.
It is also given that:
The ratio of tablespoons to fluid ounces is 2 : 1.
by proportion definition we have;
by cross multiply we have;
3 = 2x
Divide both sides by 2 we have;
therefore, fluid ounces of milk does Monica use.”
Step-by-step explanation:
18. It would be the second graph. The third graph is eliminated as the boy takes a time period to shave, which means there should be a constant point (horizontal line) right after the first incline. The first one is eliminated as the boy takes a bath which requires another constant point in the graph.
