Q.

T=29-8a

\newline

The 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?

\newline

Choose

1

answer:

\newline

(A) The temperature on the ground is

29

degrees Celsius.

\newline

(B) The weather balloon reaches a maximum altitude of

29

kilometers.

\newline

(C) The temperature increases by

29

degrees Celsius for every kilometer increase in altitude.

\newline

(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.
