32) Identify the turning point of the function f(x)= x^2-2x+8 by writing its equation in vertex form. Show your work.

Answers

(1,7)

Working;
Start by finding the derivative of the function f(x);
$f^(') (x)$ =2x-2
Turning points occur when the derivative function=0;
Thus
2x-2=0
x=1
when x=1 then
f(1)= $1^(2) -2(1)+8$
=7
Turning point then is (1,7)

Molly is filling a pitcher that holds 2 gallons of water. She is filling the pitcher with a 1-cup measuring cup. How many times will she have to fill the cup 1-cup measuring cup to fill the pitcher

Answers

Answer:

32 times

Step-by-step explanation:

Molly is filling a pitcher that holds 2 gallons of water.

1 gallon = 16 cups

So, 2 gallons = $16* 2=32 cups$

So, it requires 32 cups to fill the pitcher.

Since we are given that She is filling the pitcher with a 1-cup measuring cup.

So, no. of times she will have to fill the cup 1-cup measuring cup to fill the pitcher = $(32)/(1)=32$

Hence she will need to fill cup 1-cup measuring cup 32 times to fill the pitcher.

2 cups in a pint
2 pints to a quart (therefore 4 cups to a quart)
4 quarts to a gallon (therefore 16 cups to a gallon)
And finally 2 gallons to 2 gallons (therefore 32 cups to 2 gallons)

32 times
