4 weeks is half of 8 so you have to multiply 297 by 2 to find 8 weeks. The answer is " he saved $594 during 8 weeks"
Answer:
The ratio of the average change in profit when the level of production changes from 600 to 620 units per month is -24 : 5.
Step-by-step explanation:
The question is:
A company knows that if it produces "x" monthly units its utility "u" could be calculated with the expression: u (x) = - 0.04x ^ 2 + 44x-4000 where "u" is expressed in dollars. Determine the ratio of the average change in profit when the level of production changes from 600 to 620 units per month. Remember that the slope of the secant line to the graph of the function represents the average rate of change.
Solution:
The expression for the utility is:
It is provided that the slope of the secant line to the graph of the function represents the average rate of change.
Then the ratio of the average change in profit when the level of production changes is:
Compute the values of u (x₁) and u (x₂) as follows:
<em>x</em>₁ = 600
<em>x</em>₂ = 620
Compute the average rate of change as follows:
Thus, the ratio of the average change in profit when the level of production changes from 600 to 620 units per month is -24 : 5.
Answer: 6
Step-by-step explanation: 12*3=36; square root 36 is 6.
Short answer 34/13Start by converting both to improper fractions.
8 1/2 = (2*8 + 1)/2 = 17/2
3 1/4 = (3*4 + 1)/4 = 13/4
Next set up a 4 layer fraction
Invert the lower fraction and multiply
Cancel the 2 and the 4 leaving you with a 2 in the numerator.
