Answer:

17/50

Step-by-step explanation:

3/10 is equivalent to 30/100. 30/100+4/100=34/100. Both numbers are divisible by two, so you can get 17/50.

Letter A company charges a flat rate of $129 (yearly) for AP and $7.99 for each HD movie rental.
Arada [10]

c) You must rent 5 movies from each company to have equal bills.

d) The dollar amount would be $168.95 when the bills are equal which can be determined by putting x=5 in both function.

Step-by-step explanation:

Given,

Yearly charges of Letter A = $129

Per movie rent = $7.99

Let,

x be the number of rental movies.

A(x) = Yearly charges + Per movie rent*Number of movies rented

A(x) = 129 + 7.99x

Yearly charges of YR = $144

Per movie rent = $4.99

Y(x) = 144+4.99x

c) Solve the system of equations to determine how many movies you must rent from each company to have equal bills.

For equal bills;

A(x) = Y(x)

129+7.99x=144+4.99x\\7.99x-4.99x=144-129\\3x=15

Dividing both sides by 3

\frac{3x}{3}=\frac{15}{3}\\x=5

You must rent 5 movies from each company to have equal bills.

d) What would be the dollar amount when the bills are equal? How did you get that answer?

We will use x=5 to check the dollar amount.

A(5)=129+7.99(5)\\A(5)=129+39.95\\A(5)=168.95

Y(5) = 144+4.99(5)\\Y(5) = 144+24.95\\Y(5) = 168.95

The dollar amount would be $168.95 when the bills are equal which can be determined by putting x=5 in both function.

If a = 5+2√6 then find a²-1÷a²
Umnica [9.8K]

Answer:

a²+1/a² = 7

Step-by-step explanation:

Given, a = (3+√5)/2

We have to find the value of a² + 1/a².

1/a = 1/((3+√5)/2) = 2/(3+√5)

By taking conjugate,

2/(3+√5) = 2/(3+√5) × (3-√5)/(3-√5)

= 2(3-√5) / (3+√5)(3-√5)

By using algebraic identity,

(a - b)(a + b) = a² - b²

(3+√5)(3-√5) = (3)² - (√5)²

= 9 - 5

= 4

2(3-√5) / (3+√5)(3-√5) = 2(3-√5) / 4

So, 1/a = (3-√5)/2

Now, a² = [(3+√5)/2]²

= (3+√5)²/4

By using algebraic identity,

(a + b)² = a² + 2ab + b²

(3+√5)² = (3)² + 2(3)(√5) + (√5)²

= 9 + 6√5 + 5

= 14 + 6√5

a² = (14+6√5)/4

= 2(7+3√5)/4

a² = (7+3√5)/2

Now, 1/a² = [(3-√5)/2]²

= (3-√5)²/4

By using algebraic identity,

(a - b)² = a² - 2ab + b²

(3-√5)² = (3)² - 2(3)(√5) + (√5)²

= 9 - 6√5 + 5

= 14 - 6√5

1/a² = (14-6√5)/4

1/a² = (7-3√5)/2

a²+1/a² = (7+3√5)/2 + (7-3√5)/2

= 7/2 + 3√5/2 + 7/2 - 3√5/2

= 7/2 + 7/2

= 7

Therefore, a²+1/a² = 7
