Answer:
x(t) = 37cos(70o)t and y(t) = –16t2 + 37sin(70o)t
Step-by-step explanation:
The number of hours since the bakery opened, plus the number of remaining boxes is equal to 42.
x + y = 42
So the number of boxes remaining is equal to y, and
y = 42 - x, the number of hours the bakery was open.
So at the start of the day, the bakery was open for 0 hours, and y, the number of boxes "remaining" at the start of the day, will be equal to 42 - 0 = 42.
The answer is c because
when you y -1 = ( x - 5)
1- 1 = 5 -5
0 = 0
where A y - 5 = ( x - 1)
1 - 5 = ( 5 - 1 )
-4 dosenot equal 4
37.5 = initial rate
44.9 = slope/rate
In problems like these, just use y = initial rate + rate(variable)
In this case, the answer would be y = 37.5 + 44.9h
Answer:
23833.41cm²
Step-by-step explanation:
A=πr2=π·87.12≈23833.40992cm²
That rounds up to 23833.41cm²
