Answer:
7.7km
Step-by-step explanation:
Answer:
y+3=-2(x-5)
Step-by-step explanation:
The point slope form is y-y1=m(x-x1) where m= slope and y1 and x1 are your point.
I don't see any pattern but if there has to be then it could be that the temperature is increasing and never dropped down.
The answer is z= -3(17p+28)/d+p
Answer:
20 ft by 60 ft
Step-by-step explanation:
"What should the dimensions of the garden be to maximize this area?"
If y is the length of the garden, parallel to the stream, and x is the width of the garden, then the amount of fencing is:
120 = 3x + y
And the area is:
A = xy
Use substitution:
A = x (120 − 3x)
A = -3x² + 120x
This is a downward facing parabola. The maximum is at the vertex, which we can find using x = -b/(2a).
x = -120 / (2 · -3)
x = 20
When x = 20, y = 60. So the garden should be 20 ft by 60 ft.
