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:
If traingles are similar, then corresponding sides are in proportion:
cross multiply
divide both sides by 40
Answer:
9.7 rounded to 10
Step-by-step explanation:
I'm pretty sure 10 would be the answer, because since they are similar triangle you would cross multiply. So you would do , you would the cross multiply 23×17 and 40×X. You would then have 40X=391, so you would divide 391÷40, so X=9.7 or 10
Answer:
Domain: (-∞, ∞), or x∈R, or -∞<x<∞
Range: (-∞, ∞), or y∈R, or -∞<y<∞
Step-by-step explanation:
Domain and range are all real numbers. Domain is all values of x, range is all values of y.
Domain: (-∞, ∞), or x∈R, or -∞<x<∞
Range: (-∞, ∞), or y∈R, or -∞<y<∞
