Answer: The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
Step-by-step explanation:
Answer:
B. 0.083 rounded to the nearest thousandth.
Step-by-step explanation:
It is known that 12 inches = 1 foot and
60 minutes = 1 hour
Since we want to covert from inches per hour to feet per minute, then we would change 60 inches to feet in 1 hour 2 minutes in divide.
If 12 inches = 1 foot, then
60 inches = 60/12 = 5 feet
Therefore, the number of feet that she sews in a minute is
5/60 = 0.083 feet per minute
She sews 0.083 feet per minute.
This is the full explanation for this question.
