What is the vertex for the following quadratic? f(x)= 2x^2-12x+16

Mathematics

Answer:

(3, -2)

Step-by-step explanation:

To find the vertex, put the equation into vertex form by completing the square

2(x^2 - 6x) + 16  [pulling out the 2]

2(x^2 - 6x + 9) - 18 + 16 [completing the square, you subtracted 2*9 = 18 so you also add 18]

2(x - 3)^2 - 2 [simplify the equation]

vertex is (3, -2)

Can someone explain end behaviors and answer this question?
Luda [366]

Answer:

End behaviors are basically what the function looks like as it ends.

as x approaches positive infinity (the sideways 8) its increasing.

for the picture i believe the answer is C.

Step-by-step explanation:

basically because when you look at where the negatives are they continue which means it’s -infinity and so as the function approaches -infinity it’s x —> positive infinity and same thing for as x approaches positive infinity.

A line has a slope of zero and passes through the point (-2, 3). Which of the following points must also lie on the line?
brilliants [131]

Answer:

(5,3)

Step-by-step explanation

Because the slope is 0, it means its a horizontal line. because the horizontal is on 3, then it doesnt  matter what x is as long as y is 3 if that makes any sense.

A certain substance has a half-life of 4 minutes. A fresh sample of the substance weighing 90 mg was obtained. After how many mi
sveticcg [70]
  • We are to find the time (number of minutes) is would take for 23 mg of the substance to be remaining.

  • The formula for time is written as:

t =  [t1/2 x In(Nt/No)]  / In 2

where:

t1/2 = Half life = 4 minutes

No = Initial quantity of the sample = 90 mg

Nt = Amount of the sample left = 23 mg

t =  time elapsed = ?

Hence,

t = [4 x In (23/90)] / -In 2

t = 7.8731645610906 minutes

Approximately to the nearest hundredth = 7.87 minutes

Therefore, there will be 23mg of substance remaining after 7.87 minutes.
