Rewrite the function by completing the square.<br><br> f(x)=x^2-4x-26

Radda [10]

Answer:

$(x-2)^2-30$

Step-by-step explanation:

use the form $ax^2+bx+c$ to find the values of a, b, and c.

$a=1, b= -4, c = -26$

consider the vertex form of a parabola

$a(x+d)^2+e$

substitute the values of a and b into the formula $d=\frac{b}{2a}$

$d=\frac{4}{2(1)}$

simplify the right side.

find the value of e using the formula $e=c-\frac{b^2}{4a}$

$e=30$

how would you solve 4c + 11 = -25? explain how in complete sentences and list the solution. (yall im so lost in class rn, i need

hichkok12 [17]

Answer:

Step-by-step explanation:

4c + 11 = -25

4c = -25 - 11

4c = -36

c = -36 : 4

c = -9

4c + 11 + 25 = 0

4c + 36 = 0

c = (-36)/4

c = -9

-------------------

check

4 *(-9) + 11 = -25

-36 + 11 = -25

-25 = -25

the answer is good

Despite tuition skyrocketing, a college education is still valuable. Recent calculation by the federal reserve bank in San Franc

insens350 [35]

Answer:

The variance is: $169,367,949

Step-by-step explanation:

Given

Tuition: $40,632, $35,554, $42,192, $33,432, $69,479, and $43,598

Required

Determine the variance

First, calculate the mean

$\bar x = \frac{\sum x}{n}$

Where

$n =6$

$\bar x = \frac{40,632+35,554+42,192+33,432+69,479+43,598}{6}$

$\bar x = \frac{264,887}{6}$

$\bar x = 44147.8333333$

$\bar x = 44148$ --- approximated

The sample variance (s^2) is calculated using:

$s^2 = \frac{\sum(x - \bar x)^2}{n-1}$

This gives:

$s^2 = \frac{(40,632-44148)^2+(35,554-44148)^2+(42,192-44148)^2+(33,432-44148)^2+(69,479-44148)^2+(43,598-44148)^2}{6-1}$

$s^2 = \frac{846839745}{5}$

$s^2 = 169367949$

<em>The variance is: $169,367,949</em>
