Answer:
f(n) = n/36
Step-by-step explanation:
The length of a string is given in yards, is a function f(n) of the length n in inches.
We have to write a function rule for this situation.
∵ 36 inches = 1 yard
∴ 1 inch = 1/36 (yard)
∴ n inches = n/36
and function representing the length will be
f(n) = n/36
x^2 – 6x = 20
b=-6
to complete the square, add (b/2)^2 to each side
(b/2)^2 = (-6/2)^2=(-3)^2 =9
x^2 – 6x +9 = 20+9
(x+b/2) ^2 =29
(x-3)^2=29
take the square root of each side
x-3 = +- sqrt (29)
add 3 to each side
x = 3+- sqrt (29)
x = 3 + sqrt(29), x- sqrt(29)
Answer: -2.39, 8.39
13 - (-3) = 16 and 13 + 3 = 16. A number minus a negative is the same as addition
