The bar graph shows the estimated number of calories per day needed to maintain energy balance for various gender and age groups for sedentary lifestyles. (Sedentary means a lifestyle that includes only the light physical activity associated with typical day-to-day life.) Use the appropriate information displayed by the graph to solve Exercises 69-70.

- Graph 9x2+16y2=144.arrow_forwardI am really struggling with 1-23arrow_forwardThe bar graph shows discretionary spending by full and part-time college students in some country from 2007 through 2013. The data in the graph can be modeled by the formula D=1.2x +1.6(x+40), where D represents discretionary spending among students, in billions of dollars, x years after 2007. According to the formula, how much money did college students spend in 2007? Does the model underestimate or overestimate the amount of discretionary spending displayed by the bar graph? By how much?

- Drag the three points so they simultaneously follow both a LINEAR pattern and an EXPONENTIAL patternarrow_forwardThanks. How do you calculate this answer using the graphing calculator instead of Excel?arrow_forwardUse these model equations: the linear equation y=0.225x+12.45, the quadratic equation y=0.0032(x-30)*2+19.2, and the exponential equation y=1.90(1,08)*x a) Graph each equation on the same grid.

- College students are graduating with the highest debt burden in history. The bar graph shows the mean, or average, student-loan debt in the United States for five selected graduating years from 2001 through 2013. Here are two mathematical models for the data shown by the graph. In each formula, D represents mean student-loan debt, in dollars, x years after 2000. The Model 1 is, D = 1188x + 16,218 and the Model 2 is D = 46x2 + 541x + 17,650. Solve, a. Which model better describes the data for 2001?b. Does the polynomial model of degree 2 underestimate or overestimate the mean student-loan debt for 2013? By how much?arrow_forwardPediatric growth charts suggest a linear relationship between age (in years) and median height (in inches) for children between 2 and 12 years of age. Two year olds have a median height of 35 inches and 12 year olds have a median height of 60inches. Generate an equation to describe height as a of age. A) H(a)= -2.5a + 30 B) H(a)= 2.5a + 35 C) H(a)= 2.5a - 30 D) H(a)= .4a - 12 E) H(a)= 2.5a + 30arrow_forwardKathy puts $3000 into an account that pays 5% simple interest annually.a) Create a linear model to relate the amount of the investment, A, to time, t, in years.b) Graph the amount of the investment versus time.c) How long will it take for Kathy’s investment to double in value?d) What interest rate is required for the investment to double in value in 10 years?arrow_forward

Equation: Greg is driving on the highway. He begins the trip with 18 gallons of gas in his car. The car uses up one gallon of gas every 25 miles. Let G represent the number of gallons of gas he has left in his tank, and let D represent the total distance (in miles) he has traveled. Write an equation relating G to D, and then graph your equation using the axes below.
