The required temperature at the height of 1200 meters is 13 degree Celcius.
Given that,
Temperature drops an average of 1 degree celsius for every 100 meters that a hot air balloon rises.
The temperature is 25 degrees celsius on the ground.
The approximate temperature is 1200 meters above the ground is to be determined.
<h3>What are functions?</h3>
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The expression of for temperature drops an average of 1-degree celsius for every 100 meters that a hot air balloon rises.
Let x be the height in meters and y be the temperature in degrees celcius
y = -x/100 + 25
For temperature 1200 meters above ground
x = 1200
y = -1200/100 + 25
y = -12 + 25
y = 13
Thus, the required temperature at the height of 1200 meters is 13 degrees Celcius.

Answer:
77 m
Step-by-step explanation:
The geometry can be modeled by a right triangle. The distance from the viewpoint to the base of the tower is 110 m, the leg of the triangle adjacent to the angle. The height of the spire is the leg of the triangle opposite the given angle. The relevant trig relation is ...
Tan = Opposite/Adjacent
__
Using the given numbers, we find ...
tan(35°) = height/(110 m)
height = (110 m)tan(35°) = (110 m)×0.700208 ≈ 77.0 m
The height of the tower is about 77 meters.
Answer:
5.14 mi/h
Step-by-step explanation:
To find the average speed, we simply find the total distance traveled by Tom and divide that by the total time the entire journey took him.
Average speed = (total distance traveled) / (total time taken)
TOTAL DISTANCE TRAVELED
He traveled 3 miles to and 3 miles fro. Hence:
3 + 3 = 6 miles
TOTAL TIME TAKEN
He spent ½ hr to go and ⅔ hr to return back. Hence:
½ + ⅔ = 7/6 hr
Therefore, the average speed is:
v = 6 / (7/6)
v = 36 / 7 = 5.14 mi/h
Tom's average speed was 5.14 mi/h.
