(a)

Answer to Problem 45E
The graph the decade of
Explanation of Solution
Given information:
Use the graph of minimum wages in the United States from 1950 through 2015.
Calculation:
Use the graph of minimum wages in the United States from 1950 through 2015 and find the decade of the greatest increase, the percentage increases in the minimum wage.
With the help of the graph the decade of
Conclusion:
The graph the decade of
(b)
That the percent increases in the minimum wage from 1985 to 2000 and from 2000 to 2015.
(b)

Answer to Problem 45E
From 1985 to 2000 the percent increase in the minimum wage is 57.7%
From 2000 to 2015 the percent increase in the minimum wage is 41.5%
Explanation of Solution
Given information:
Use the graph of minimum wages in the United States from 1950 through 2015.
Calculation:
With the help of the graph the wage is $3.25 in 1985, the wage is $5.125 in 2000 and the wage is $7.25 in 2015.
From 1985 to 2000 the percent increase in the minimum wage will be
From 2000 to 2015 the percent increase in the minimum wage will be
Conclusion:
From 1985 to 2000 the percent increase in the minimum wage is 57.7%
From 2000 to 2015 the percent increase in the minimum wage is 41.5%
(c)
The percent increase from 2000 to 2015 to predict the minimum wage in 2030.
(c)

Answer to Problem 45E
The minimum wage is $10.26 in 2030.
Explanation of Solution
Given information:
Use the graph of minimum wages in the United States from 1950 through 2015.
Calculation:
Use the percent increase from 2000 to 2015 and the minimum wage in 2030 will be
Therefore, the minimum wage is $10.26 in 2030.
Conclusion:
The minimum wage is $10.26 in 2030.
(a)
The prediction is reasonable.
(a)

Answer to Problem 45E
The prediction is not reasonable.
Explanation of Solution
Given information:
Use the graph of minimum wages in the United States from 1950 through 2015.
Calculation:
The prediction is not reasonable.
No, the prediction is too high because it is likely that the percent increased.
Conclusion:
The prediction is too high because it is likely that the percent increased.

- Consider the region below f(x) = (11-x), above the x-axis, and between x = 0 and x = 11. Let x; be the midpoint of the ith subinterval. Complete parts a. and b. below. a. Approximate the area of the region using eleven rectangles. Use the midpoints of each subinterval for the heights of the rectangles. The area is approximately square units. (Type an integer or decimal.)arrow_forwardRama/Shutterstock.com Romaset/Shutterstock.com The power station has three different hydroelectric turbines, each with a known (and unique) power function that gives the amount of electric power generated as a function of the water flow arriving at the turbine. The incoming water can be apportioned in different volumes to each turbine, so the goal of this project is to determine how to distribute water among the turbines to give the maximum total energy production for any rate of flow. Using experimental evidence and Bernoulli's equation, the following quadratic models were determined for the power output of each turbine, along with the allowable flows of operation: 6 KW₁ = (-18.89 +0.1277Q1-4.08.10 Q) (170 - 1.6 · 10¯*Q) KW2 = (-24.51 +0.1358Q2-4.69-10 Q¹²) (170 — 1.6 · 10¯*Q) KW3 = (-27.02 +0.1380Q3 -3.84-10-5Q) (170 - 1.6-10-ºQ) where 250 Q1 <1110, 250 Q2 <1110, 250 <3 < 1225 Qi = flow through turbine i in cubic feet per second KW = power generated by turbine i in kilowattsarrow_forwardHello!
