Answer:

yearly cost for housing expenses = $11,400, average monthly cost for food = $650

yearly clothing cost = $900,

average monthly cost for transportation= $500,

Yearly cost for insurance & medical= $14,400

yearly cost for emergency fund = $600

average monthly college saving = $50

Step-by-step explanation:

Yearly housing = monthly cost * 12 = 950 * 12 = 11400

Food, monthly = 7800 /12 = 650

Clothing, yearly = 75 * 12 = $900

Monthly transport = 6000 / 12 = $500

Insurance and medical = 1200*12 =14400

Emergency fund = $50 * 12 = $600

College saving = $600 / 12 = $50

Answer:

(y,z)=(3,5)\\\\ |(y,z)|=\sqrt{34}

Step-by-step explanation:

Given y(3, 1), z(0, 4)

-The ordered pair is written by summing their corresponding coordanates as below:

(y,z)=y(3,1)+z(0,4)\\\\=(3+0,1+4)\\\\=(3,5)

-We then calculate the magnitude of this ordered pair as following:

|y,z|=\sqrt{y^2+z^2}\\\\=\sqrt{3^2+5^2}\\\\=\sqrt{34}\\\\\therefore |(y,z)|=\sqrt{34}

Hence, the magnitude of the ordered pair is \sqrt{34}

Which of the following is an extraneous solution of mc015-1.jpg? x = –12 x = –3 x = 3 x = 12
kramer
The answer
the full the question is as follow:
<span>Which of the following is an extraneous solution of (45 - 3x)^1/2 =x -9

for solving such an equation, this is the method:

finding the squared value of each member of the equation
</span>[(45 - 3x)^1/2 ]²  = (x -9)²   (E)
<span>
extend each value of the member
</span>[(45 - 3x)^1/2 ]² = 45 - 3x, because   (sqrt a )² = a
the condition is 45 - 3x≥0 ( because of the square root)
it means  - 3x≥ -45 and  x ≤ 15

(x -9)² = x²-18x + 81
<span>
so </span>45 - 3x = x²-18x + 81, this is equivalent to x² - 15x  +36 =0
<span>
this equation should solve for x, for finding the help

Delta = 15² - 4*36 = 81, so x = - (-15) - sqrt (81)  /  2 *1=15-9 /2= 3

                                      and </span>x = - (-15) +sqrt (81)  /  2 *1= 15 +9/2= 24/2=12
<span>
for x= 12, the equation given above ( equation E) has no solution, because 
we can find 3=9

so </span><span>an extraneous solution is x = 12</span><span>

</span>
