Answer: The approximate f(1.1,-0.1) is 4.92.
Step-by-step explanation:
Since we have given that
at (1,0),
we get
Partial derivative would be
So,
Similarly,
So,
Now,
L(1.1,-0.1)=
and
f(1.1,-0.1) =
Hence, the approximate f(1.1,-0.1) is 4.92.
Answer:
LOOK IN NOTES
Step-by-step explanation:
X is greater then -4 because x is just one
See my diagram
I'm assuming that your swimming pool is an oval or something like that
remember that the area of an oval is r₁r₂π where r₁ and r₂ are the 2 radii
so
we must do big oval-small oval
the radius is half of the diameter
calculating smalller oval area
it is 32 by 18
those are diameter
halve them
16 by 9
so the area is 16*9*pi or 144pi square feet
big oval area
add 3 feet to each side, so 6 feet total to each dimention
the big oval has diameters of 32+6 and 18+6 or 38 and 24
halve them to find the radii
19 and 12
the area is 19*12*pi or 228pi
so the area that is concrete=228pi-144pi=84pi squaer feet or about 263.89 square feet
