Answer:

x=9

Step-by-step explanation:

(x+3)/2=6​

A company pays $3.91 million to air a 30- second commercial during a football game that is watched by approximately 115 million
Radda [10]

Answer:

Part 1) The cost per second is \$130,333.33

Part 2) The cost per customer is \$0.034

Step-by-step explanation:

Part 1) Calculate the cost per second

we know that

To find out the cost per second, divide the total cost by the time

Let

x ----> the total cost

y ----> the time in seconds

we have

x=\$3,910,000

y=30\ sec

\frac{\$3,910,000}{30}=\$130,333.33

therefore

The cost per second is \$130,333.33

Part 2) Calculate the cost per customer

we know that

To find out the cost per customer, divide the total cost by the number of customers

Let

x ----> the total cost

y ----> the number of customers

we have

x=\$3,910,000

y=115,000,000\ customers

\frac{\$3,910,000}{115,000,000}=\$0.034

therefore

The cost per customer is \$0.034

If x=3+root8 and y =3- root 8 find 1/x^2+1/y^2
KonstantinChe [14]

Answer:

34

Step-by-step explanation:

x=3+√8

y =3-√8

now,

1/x^2+1/y^2

=1/(3+√8)² + 1/(3-√8)²

= [(3-√8)²+(3+√8)²] / (3+√8)²(3-√8)²            [L.C.M  = (3+√8)²(3-√8)² ]

=[(3-√8+3+√8)²-2(3-√8)(3+√8) ] / [(3+√8)(3-√8)]²  

=[6²-2.(3²-√8² )] / (3²-√8²)²                 [ a²+ b²=(a+b)²-2ab]

=[36-2(9-8) ]/ (9-8)²

=[36-2.1] / 1²

=34
