Teacher functions & modeling quiz 3 name date 1) it takes 10 minutes to preheat your oven to 325 degrees. for an oven preheated to 325 degrees, the recommended cooking time for a turkey is about 16 minutes per pound a) use a formula to express the total time 7, in minutes, needed to preheat the oven and then bake a turkey weighing p pounds. b) (i point) use your formula from part a to find the approximate time required to prepare a turkey weighing 14 pounds. make sure to use function notation and include units. 2) the total number t of items that a manufacturing company can produce is directly proportional to the number of employees a) (i point) write an equation that shows the proportionality relation. let 15 be the constant of proportionality. b) ( point) what, in practical terms, does the constant of proportionality represent in this case? circle your answer. a) it is the number of employees. b) it is the total number of items produced. c) it is the number of items produced per employee. d) it cannot be determined.

so what is the problem what are they asking you to solve

step-by-step explanation:

so what is the problem what are they asking you to solve

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
