- The relation T= 190(2) 16 can be used to determine the length of time, t, in hours, that milk of a certain fat content will remain fresh.
T'is the storage temperature, in degrees Celsius.
a) What is the freshness half-life of milk?
b) Graph the relation.
How long will milk keep fresh at 22°C? at 4°C?

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

i believe b is the answer
