Question 9 (1 point)

Likurg_2 [28]

Answer:

A piece of Jewelry costs $4.5 and a hair accessory costs $1.5.

Step-by-step explanation:

Let the price of a piece of jewelry is $x and that of a piece of hair accessories is $y.

So, from the given conditions we can write two different equations as

5x + 8y = 34.5 ............ (1) and

2x + 16y = 33 ............... (2)

Now, solving the equations (1) and (2) we get

2x + 2(34.5 - 5x) = 33

⇒ 8x = 36

⇒ x = $4.5

Again, from the equation (2) we can write

2(4.5) + 16y = 33

⇒ 16y = 24

⇒ y = $1.5

Therefore, a piece of Jewelry costs $4.5 and a hair accessory costs $1.5. (Answer)

Find the first six terms of the sequence described by the following recursive formula: an = an – 1 + an – 2 where a3 = -5 and a4

solmaris [256]

Answer:

Now we have: -13, 8, -5, 3, -2, 1

Step-by-step explanation:

This is a Fibonacci sequence.

though modified.

so a_n = a_(n-1) + a_(n-2)

with a_3 = -5,

a_4 = 3

a_3 = -5 = a_2 + a_1

a_4 = 3 = a_3 + a_2 = -5 + a_2

then a_2 = 3 + 5 = 8

then.

a_3 = -5 = a_2 + a_1 = 8 + a_1

a_1 = -5 - 8 = -13

We now have: -13, 8, -5, 3, ....

Now we can find a_5 and a_6

a_5 = a_4 + a_3 = 3 + -5 = -2

a_6 = a_5 + a_4 = -2 + 3 = 1

Now we have: -13, 8, -5, 3, -2, 1
