- Measurement Use the fact that 13 inches is approximately the same length as 33 centimeters to find a mathematical model that relates centimeters y to inches x. Then use the model to find the numbers of centimeters in 10 inches and 20 inches.arrow_forwardHOW DO YOU SEE IT? In parts (a)-(c) use the graph to determine whether the discriminant of the given equation is positive, zero, or negative. Explain. (a) x22x=0 (b) x22x+1=0 (c) x22x+2=0arrow_forwardMeasurement Use the fact that 14 gallons is approximately the same amount as 53 liters to find a mathematical model that relates liters y to gallons x. Then use the model to find the numbers of liters in 5 gallons and 25 gallons.arrow_forward
- Architecture The arch support of a bridge is modeled by y=0.0012x2+300 where x and y are measured in feet and the x-axis represents the ground. (a) Use a graphing utility to graph the equation. (b) Identify one x-intercept of the graph. Explain how to use the intercept and the symmetry of the graph to find the width of the arch support.arrow_forwardGraphical Reasoning In Exercises 47-50, determine the x-interceptsof the graph visually. Then find the x-interceptsalgebraically to confirm your results. y=x24x5arrow_forwardApplications In Exercises 81-91, assume straight-line depreciation or straight-line appreciation. Depreciation A surfing van was purchased for 24,300. Its salvage value at the end of its 7-year useful life is expected to be 1900. Find a depreciation equation.arrow_forward
