Step-by-step explanation:

<u>Standard form:</u>

  • y = ax² + bx + c

<u>Vertex form:</u>

  • y = (x - h)² + k

<u>Identity used:</u>

  • (a ± b)² = a² ± 2ab + b²

6 - 7)

<u>Standard to vertex form conversion by completing the square</u>

y = x² - 3x + 16

  = x² - 2*1*3/2 + (3/2)² - (3/2)² + 16

  = (x - 3/2)² - 9/4 + 16 =

  = (x - 1.5)² + 13.75

8 - 9)

<u>Same as above</u>

y = x² - 2x + 3

  = x² - 2*1*x + 1² - 1² + 3

  = (x - 1)² + 2

10 - 12)

<u>Vertex to standard for conversion by opening parenthesis and simplification</u>

y = (x - 11)² + 15

  = x² - 22x + 121 + 15

  = x² - 22x + 136

13-15)

<u>Same as above</u>

y = (x - 4)² + 11

  = x² - 8x + 16 + 11

  = x² = 8x + 27

Find the inverse of the following function. f(x) =^3squareroot x + 12<br><br> I NEED AN ANSWER NOWW
makkiz [27]

Answer:

(x - 12)²/9

Step-by-step explanation:

y = 3sqr(x) + 12

Make x the subject:

y - 12 = 3sqrt(x)

(y - 12)/3 = sqrt(x)

Square both sides

(y - 12)²/9 = x

Interswitch variables

inverse function is:

(x - 12)²/9

If f(x) = (x + 12)^⅓

Then,

y = (x + 12)⅓

y³ = x + 12

y³ - 12 = x

f inverse:

x³ - 12

A group of 50 New York psychology students got a mean score of 530 on the psychology GRE with a standard deviation of 80. These
lesantik [10]

Answer: No, New York students are not truly more nerdy than the California students.

Step-by-step explanation:

Since we have given that

Number of students in a group = 50

Mean score of New York psychology = 530

Mean score of California psychology = 515

Standard deviation = 80

So, we will find t-distribution first.

t=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\t=\dfrac{530-515}{\dfrac{80}{\sqrt{50}}}\\\\t=1.32

Let α = 5% = 0.05

So, t_{\alpha,2}=2.920

Since t < t(critical value)

No, New York students are not truly more nerdy than the California students.
