Q. T=29−8aThe temperature, T, in degrees Celsius, as measured by a weather balloon at an altitude of a kilometers from the ground is given by the equation. What is the best interpretation of 29 as shown in the given equation?Choose 1 answer:(A) The temperature on the ground is 29 degrees Celsius.(B) The weather balloon reaches a maximum altitude of 29 kilometers.(C) The temperature increases by 29 degrees Celsius for every kilometer increase in altitude.(D) The temperature decreases by 29 degrees Celsius for every kilometer increase in altitude.
Substitute a=0: The equation given is T=29−8a. To interpret the number 29, we need to consider what happens when the altitude a is zero. If we substitute a=0 into the equation, we get T=29−8(0).
Calculate T when a=0: Calculating the value when a=0, we have T=29−0, which simplifies to T=29. This indicates that at an altitude of 0 kilometers (ground level), the temperature is 29 degrees Celsius.
Interpretation of 29: Now, we need to determine which answer choice corresponds to our calculation. The correct interpretation of 29 in the equation is that it represents the temperature at ground level. Therefore, the correct answer is (A) The temperature on the ground is 29 degrees Celsius.
