Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long. Let y represent the length
2 answers:
Answer:
, the graph will be continuous.
Step-by-step explanation:
Given: Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long, y represent the length of each of the equal pieces of yarn that Julie decides to cut, t represents total length of yarn.
To Find: Equation to determine the total length of yarn, and find if graph is discrete or continuous.
Solution:
total number of piece to be cut from yarn =
length of four equal pieces of yarn=
length of fifth piece of yarn =
now,
total length of yarn is
rewriting equation
as length of piece of yarn can be any real number, the graph will be continuous.

Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)
another way to do it:
f(x)=x²-10x+16
the vertex is when x=-
, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
f(x)=x²-10x+16
