Question

Under certain air conditions, the air temperature drops about 3.9°F for each 1,000-foot rise in altitude. Complete parts (A) and (B) below. (A) If the temperature at sea level is 67°F, write a linear equation that expresses temperature T in terms of altitude A in thousands of feet. (B) At what altitude is the temperature 24.1°F? (A) If the temperature at sea level is 67°F, write a linear equation that expresses temperature T in terms of altitude A in thousands of feet. (Type your answer in slope-intercept form.)

Answer 1

@ the air temperature drops about 3.97 for each 1000: toat vise in altitude and temperature at sea level is 67°E (A) A linear equation that expresse temperature I in terms of altitude A in thousand of feet (Slope) b = 67 F s-ive sloke indicate a increases mx + b decreases y = 0.0039A + 6 m = -3.9 looo --00039 deg I feet then y a y put in (B) The altitude at temperature 2-4.1° F above equation 24.1 00039At 67 0.0039_A 42.9 A - 42.9 0.0039 LAE Il000 feet
