l
Length of Rectangle (cm)
w
Width of Rectangle (cm)
A
Area of Rectangle (
c

)
t
Time (s)
We are told that:
d
l
d
t
=
8
cm/s (const), and,
d
w
d
t
=
3
cm/s (const)
The Area of the rectangle is:
A
=
l
w
Differentiating wrt
t
(using the product rule) we get;
d

(

(
d

∴
d

So when
l

Answer: In order to convert Celsius to Fahrenheit, you will need to use this formula: F = 9/5C + 32. Therefore, you will need to solve for C or substitute values and solve in that manner. To find Fahrenheit temperature for -20 degrees Celsius, you can just plug it into the formula
Step-by-step explanation:
Answer:
y=1/6x -1
Step-by-step explanation:
Use point-slope form to convert it to y=mx+b.
y-y1=m(x-x1)
y+2=1/6(x+6)
Distribute and simplify.
y+2=1/6x+1
y=1/6x-1
