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.

Option A

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

Solution:

Given that,

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

From above information,

5:00   72°F

5:10 400°F

5:45 400ºF

6:55 72°F

Thus at any given time (input) the oven was exactly one temperature  (a single output )

Therefore the statement that best explains is:

Option 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

option a

Step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
