A roast turkey is taken from an oven when its temperature has reached 185°F and is placed on a table in a room where the tempera
ture is 75°F.
The graph shows how the temperature of the turkey decreases and eventually approaches room temperature.
By measuring the slope of the tangent, estimate the rate of change of the temperature after an hour.

<u>Step-by-step explanation:</u>
Chen had to divide by
. To make it easier to divide, he thought of multiplying both the dividend and the divisor by 10.
Chen multiplied the divisor by 10 but mistakenly multiplied the dividend by 100 instead of 10.
So his whole division problem was changed.
Therefore, the correct answer option is B. He multiplied the dividend by 100 instead of 10.
Answer:
The maximum cost is 41 dollars per necklace.
Step-by-step explanation:
The average cost in dollars/necklace is given by :
.....(1)
Where
x is the number of necklaces that are created
To maximize the cost, find the value of x by putting dC/dx = 0
Now put the value of x = 7 in equation (1).
Hence, the maximum cost is 41 dollars per necklace.
