Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?
Alexus [3.1K]
<h3>Answer:</h3>

option A

f(x) = (x – 1)2 + 3

<h3>Step-by-step explanation:</h3>

Given in the question a function,

f(x) = 4 + x² – 2x

Step 1

f(x) = 4 + x² – 2x

here a = 1

        b = -2

        c = 4

Step 2

x = -b/2a

h = -(-2)/2(1)

h = 2/2

h = 1

Step 3

Find k

k = 4 + 1² – 2(1)

k = 3

Step 4

To convert a quadratic from y = ax² + bx + c form to vertex form,

y = a(x - h)²+ k

y = 1(x - 1)² + 3

y = (x - 1)² + 3

Do i calculate standard deviation for sample or population
Aleksandr-060686 [28]

Answer:

A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population

I have seen two answers for this and i want a third opinion, PlEaSe help me!!A man selling hotdogs, french fries, and a soda as
irina1246 [14]

Answer:

50 combos

Step-by-step explanation:

Put it into an equation first in order to find x.

2x + 250 = 7x

Subtract 2x from both sides.

250 = 5x

Then divide both sides by 5.

x = 50

Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.

<u>You can check your work by plugging in the number to both.</u>

$250 plus the $2 times 50 combo meals.

250 + 2(50) = 350

$7 times 50 combo meals

7 x 300 = 350
