Answer: The smaller piece is 750m long.
Step-by-step explanation:
let the smaller piece be x
so
150m + x + x = 1650
150 + 2x = 1650
or, 2x = 1500
so, x = 750 m

The first function represents the graph of a function provided in the picture option first is correct.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function shown in the picture.

x - 3 ≥ 0
x ≥ 3
Plug x = 3
f(x) = 2
Thus, the first function represents the graph of a function provided in the picture option first is correct.

Firstly , we will locate centres and radius in the figures
(a)
We can see that
centre=(h,k)=(0,0)
radius=r=5
now, we can use standard equation of circle

we can plug values
we get


(b)
We can see that
centre=(h,k)=(5,4)
radius=r=3
now, we can use standard equation of circle

we can plug values
we get


(c)
We can see that
centre=(h,k)=(4,3)
radius=r=5
now, we can use standard equation of circle

we can plug values
we get


all you just have to do is divide 30 by 2 which is=15
and 40 by 4=10
50 by 10=5
