Answer:

The first six numbers are -2,1,-2,1,-2,1

Step-by-step explanation:

First term is -2

The term to term rule is 'square and subtract 3'

Second term=(-2)^{2} -3=1

Third term=(1)^{2} -3=-2

Fourth term=(-2)^{2} -3=1

Fifth term=(1)^{2} -3=-2

Sixth term=(-2)^{2} -3=1

The first six numbers are -2,1,-2,1,-2,1

Assume Pina Colada Corp. uses the periodic inventory system and has a beginning inventory balance of $5800, purchases of $65000,
babymother [125]

The inventory account expected to have by December 31 is more than $5800. Option C

<h3>How to calculate the end inventory</h3>

The formula for end inventory is given as ;

Ending inventory = Beginning inventory + net purchases –sales

Beginning inventory = $5800

Net purchases = $65000

Sales = $112000

Put into the formula

Ending inventory = $ 5800 + 65000 - 112000

Add first,

Ending inventory = $ 70800 - 112000

Ending inventory = $ -41, 200

Thus, the inventory account expected to have by December 31 is more than $5800. Option C

What is the product of all constants $k$ such that the quadratic $x^2 + kx +15$ can be factored in the form $(x+a)(x+b)$, where
Setler79 [48]

Answer:

k=-16,k=-8,k=8,k=16

Step-by-step explanation:

We are given quadratic equations as

x^2+kx+15

and it can be factored as

=(x+a)(x+b)

now, we can multiply factor term

(x+a)(x+b)=x^2+(a+b)x+ab

now, we can compare

x^2+(a+b)x+ab=x^2+kx+15

so, we get

k=a+b

ab=15

we are given that

'a' and 'b' are integers

so, we can find all possible factors

15=(-1\times -15),(1\times 15)

15=(-3\times -5),(3\times 5)

so, we can find k

At (-1\times -15):

k=a+b

we can plug values

k=-1-15

k=-16

At (1\times 15):

k=a+b

we can plug values

k=1+15

k=16

At (-3\times -5):

k=a+b

we can plug values

k=-3-5

k=-8

At (3\times 5):

k=a+b

we can plug values

k=3+5

k=8

So, values of k are

k=-16,k=-8,k=8,k=16
