The supply equation for an olive oil press is
vovangra [49]

Answer:

12 units

Step-by-step explanation:

The given function is

S(q) = 5q^2 + 1000q + 100

where, S(q) is the price in dollars at which q units are supplied.

We need to find the quantity supplied in a month when the company sets the price of its olive oil press at $12,820.

Substitute S(q)=12820 in the given function.

12820 = 5q^2 + 1000q + 100

Subtract both sides by 12820.

0= 5q^2 + 1000q - 12720

Taking out GCF.

0= 5(q^2 + 200q - 2544)

Now solve the equation for q by splitting the middle term.

0= 5(q^2 + 212q-12q - 2544)

0= 5(q(q + 212)-12(q + 212))

0= 5(q + 212)(q-12)

Using zero product property we get

q + 212=0\Rightarrow q=-212

q-12=0\Rightarrow q=12

q is number of units. So the value of q can not be negative.

Therefore the quantity supplied in a month when the company sets the price of its olive oil press at $12,820 is 12 units.

  • <em>Please complete the following sentence by writing the number in the blank.   Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.</em>

<u>Candle looses 10% of 8 inches, it equals:</u>

  • 8*0.1 = 0.8 inches an hour

<u>Let x be required time, then:</u>

  • 8 - 0.8x > 7
  • 0.8x <  8 - 7
  • 0.8x  < 1
  • x  < 1/0.8
  • x  <  1.25
  • or 1 hour 15 minutes

Write the equation 9y = 12x + 0.2 in standard form. Identify A, B, and C.
uysha [10]

Answer:

A = -12, B = 9 and C = .2

Step-by-step explanation:

So it just looks like we need to use algebra to move everything around to get it in the form Ax + By = C

So, let's start with 9y = 12x + 0.2.  From standard form we have all terms wth variables on one side, so let's do that.  the right sie has both a variable term and non variable term, so let's get rid of the variable term.  The variable term is 12x, so to get rid of it you subtract 12x from both sides.

9y = 12x + 0.2

9y - 12x = 0.2

To make it exactly in standard form just rarrnge.

-12x + 9y = 0.2

So now we have A = -12, B = 9 and C = .2

17. A disposable camera costs $6.95. A party planner wants to buy 100 cameras for an
natima [27]

Answer:

$695

Step-by-step explanation:

So if each camera costs $6.95 snd he wants 100 you would multiply by 100. And that would be 6.95×100=695 and a good trick I've learnt is that you just move the numbers 1 column to the left for each zero so if it was 10 you'd move all the numbers 1 column to the left. It is abit hard to explain but you're answer is there just thought that'd help in future.
