At 5: 00 p. m., antonio turned on the oven. while the oven preheated, the temperature in the oven increased from 72°f to 400°f over a 10-minute period. the oven remained at 400°f for 45 minutes until antonio turned it off. it took 60 minutes for the temperature in the oven to cool, returning to 72°f at 6: 55 p. m. which statement best explains whether or not the temperature in the oven is a function of the time?

a. it is a function because at any given time the oven was exactly one temperature. b. it is a function because the oven temperature was the same at different times. c. it is not a function because at any given time the oven was exactly one temperature. d. it is not a function because the oven temperature was the same at different times.

The correct option is:

A. It is a function because at any given time the oven was exactly one temperature.

It is given that:

At 5:00 p.m., Antonio turned on the oven.

 The oven remained at 400°F for 45 minutes until Antonio turned it off.

It took 60 minutes for the temperature in the oven to cool, returning to 72°F at 6:55 p.m.

The statement that best explains whether the temperature in the oven is a function of the time or not is:

A.  It is a function because at any given time the oven was exactly one temperature.

( Since the definition of function states that there is a unique image corresponding to a element hence here the temperature at a given time is unique)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
