Step-by-step explanation:
it is 2/7 more than what it was (5/5)
Answer and Step-by-step explanation:
to divide 16.8 by -4, divide each number by -4.
16 divided by -4 is -4.
8 divided by -4 is -2.
<u>So, the answer is -4.2.</u>
To check our answer, we multiply the answer by -4 again.
-4.2
<u>x -4</u>
-16 .8

The convert of TT$1 020.00 to US$150.
Given that,
- US $1.00 should be equivalent to the TT $6.80.
- Now we have to convert TT $1,020 to US $.
So, the value after converting should come
= $1,020 ÷ $6.80
= $150
Therefore we can conclude that the convert of TT$1 020.00 to US$150.

Answer:
x = 28 m
y = 14 m
A(max) = 392 m²
Step-by-step explanation:
Rectangular garden A (r ) = x * y
Let´s call x the side of the rectangle to be constructed with a rock wall, then only one x side of the rectangle will be fencing with wire.
the perimeter of the rectangle is p = 2*x + 2*y ( but in this particular case only one side x will be fencing with wire
56 = x + 2*y 56 - 2*y = x
A(r) = ( 56 - 2*y ) * y
A(y ) = 56*y - 2*y²
Tacking derivatives on both sides of the equation we get:
A´(y ) = 56 - 4 * y A´(y) = 0 56 - 4*y = 0 4*y = 56
y = 14 m
and x = 56 - 2*y = 56 - 28 = 28 m
Then dimensions of the garden:
x = 28 m
y = 14 m
A(max) = 392 m²
How do we know that the area we found is a local maximum??
We find the second derivative
A´´(y) = - 4 A´´(y) < 0 then the function A(y) has a local maximum at y = 14 m
