The relation that is a function is answer D. All of the x-coordinates are all different
Answer:
false :)
Step-by-step explanation:
Y-int . . . x=0 . . . y-3 = 3 (0+1) . . . y-3 = 3 . . y=6. . . . . . . X-int .. y=0 .. 0-3=3 (x+1) .. -3=3x+3 ... -6=3x ...x=-2
Answer:
the optimal dimensions of the rectangle in order to minimize cost are
19.1 ft x 47.74 ft
Step-by-step explanation:
Assuming that the area is rectangular shaped, then
Cost = cost of the pine board fencing * length of pine board fencing + cost of galvanized steel fencing * length of galvanized steel fencing
C = a*x + b*y
that is constrained by the area
Area= A= x*y → y= A/x
replacing in C
C = a*x + b* A/x
the minimum cost is found when the derivative of the cost with respect to the length is 0 , then
dC/dx = a - b*A/x² = 0 → x = √[b/a*A]
replacing values
x = √[b/a*A] = √[($2/ft/$5/ft)*912 ft²] = 19.1 ft
then for y
y= A/x = 912 ft²/19.1 ft = 47.74 ft
then the optimal dimensions of the rectangle in order to minimize cost are
19.1 ft x 47.74 ft
Answer:
the ratio is 2 to 5, all M&M's in total 28
Step-by-step explanation:
2 green to 5 yellow.
if there are 28 M&M's
you will count by 2 every 5
2 , 4 , 6 , 8 , 10
5 , 10 , 15 , 20 , 25
There are 10 green M&M's
