The answer is 10
f(x)=x^2+1
If f(3) then you would plug that in with each x which gets you
f(3)=3^2+1
Then you figure out what 3^2 equals
(It’s should be nine) This gets you
f(3)=9+1
Which gets you
f(3)= 10

A square shed has a floor area of 156.25m square. what is the length of the diagonal

Helen [10]

------------------------------------------------------------------
Given Information
------------------------------------------------------------------
Square Area = 156.25m²

------------------------------------------------------------------
Formula
------------------------------------------------------------------
Area = Length x Length

------------------------------------------------------------------
Find Length
------------------------------------------------------------------
156.25 = Length x Length
156.25 = Length²
Length² = 156.25
Length = √156.25
Length = 12.5

------------------------------------------------------------------
Formula
------------------------------------------------------------------
a² + b² = c²

------------------------------------------------------------------
Find Diagonal
------------------------------------------------------------------
12.5² + 12.5² = c²
c² = 156.25 + 156.25
c² = 312.5
c = √312.5
c = 17.68m (nearest hundredth)

------------------------------------------------------------------
Answer: The diagonal length is 17.68m
