Determine the vertex of the function f(x)=3x^2-6x+13
Natasha_Volkova [10]

Answer:

Step-by-step explanation:

hello :

f(x)=3x^2-6x+13

1)  a=3   and  b= -6

2)  the x coordinate of the vertex is : x= -b/2a    so :  x= -(-6)/6 = 1

3) the y coordinate by x= 1 is : f(1) = 3(1)²-6(1)+13 = 10

Isabella painted her bedroom. She used 2 gallons of paint and finished in 8 hours. At what rate did Isabella paint the room?
GrogVix [38]

Answer:  " \frac{1}{4} gal /hr ;  or, write as:  " 0.25 gal/hr. " .

_______________

Step-by-step explanation:

_______________

This is a "unit rate" problem;

that is:  we want to solve for a particular quantity per [single] unit.

_______________

→ in this case, per single "hour" ;

_______________

So we convert:

_______________

" 2 gal per 8 hours" ; to the correct number of:

 _?_ gal per [single] hr.

_______________

{<u>Note</u>:  "gal" refers to:  "gallon(s)" ;

           "hr" refers to:  "hour(s)" .}.

_______________

→ " \frac{2 gal}{ 8 hr} = [\frac{2}{8}] gal / hr. " ;

_______________

→ " { \frac{2}{8} = [2÷2] / [8÷2] = 1/4 ;

_______________

So, the answer is:  

  → " \frac{1}{4} gal /hr " ;

_______________

 or: write as decimal:

  → " \frac{1}{4} = (1 ÷ 4) = 0.25 " ;

_______________

write the answer as:

_______________

  → " 0.25 gal/hr. "

_______________

Or, when we had:

 → "2/8" gal/hr ;

_______________

 Use calculator:

 → " \frac{2}{8} = "2 ÷ 8" ;

 =  " 0.25 gal/ hr.

_______________

So:  The correct answer is:

_______________

 " \frac{1}{4} gal /hr ;  or, write as:  " 0.25 gal/hr. " ;

_______________

Hope this is helpful to you!

Best wishes in your academic endeavors—

  and within the "Brainly" community!
