1 worker earns 8/hour for 40 hrs.8 times 40=320 dollars in amount for 1st worker.the 2nd worker has the same 8 hrs for 40 hours therefore the same amounts.320+320=640
as a percentage:640 divided by 2000=0.32
0.32 times 100
=32 percent for both workers.16 percent for only 1 worker<span />
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
12 inches
EXPLANATION
Let the length of the rectangular painting be inches, then the width will be inches.
Since the diagonal is the hypotenuse, we can apply the Pythagoras Theorem to find the length.
We expand to obtain;
We simplify to obtain a quadratic equation in .
We divide through by 2 to obtain.
We factor to obtain
Since we are dealing with length we discard the negative value.
Hence the length is 12 inches
