the answer is A and D
when you differentiate the question you find that the maximum point is (0,0)i.e
when dy/dx is 0 values of x are 0,0
and the function shows that valies of x are real numbers.
Answer:
30%
Step-by-step explanation:
If Justin has a 20% chance and Cam has a 50% chance that adds up to 70%
But you need to get to 100% so all you do is
70 - 100 = 30
30%
I'm almost certain it's C :)
Area of a rectangle = length (l) * width (w)
A = 30ft * 20ft
A = 600 sq ft
Now the width of a sidewalk that surroundeds it = 3 ft
so now the area of the rectangle with sidewalk= 30+3ft * 20+3ft
A = (33*23) ft
A = 759 sg ft
Area of the sidewalk = 759 - 600
A = 159 sq ft
