Rewrite as x2 -8x +7 > 0

so, (x-7)(x-1)>0

clearly the product would be >0 either when both are +ve or when both are -ve

both positive⇒x>7
both negative⇒x<1
so, "x<1 and x>7" is the answer

Digital music distribution provides an opportunity for everyone to get their music heard. In order to get on a service like iTun
Fiesta28 [93]

Based on the charge to the artist and the amount the streaming services pay, the following are true:

  1. -50.
  2. 5.
  3. y = 5x - 50
  4. .
  5. 10,000 streams.
  6. 190,010,000 streams

<h3>What model can be derived for the streaming data?</h3>

The y-intercept would be the amount that the artist has before they start making any money. In this case that amount is -$50 because they will owe the distributor.

The slope is the change per unit which is $5.00 here.

The formula is therefore:

y = mx + b

y = Slope × x + b

y = 5 × x + (-50)

y = 5x - 50

The number of streams to pay off the distributor is when the profit is $0:

0 = 5x - 50

50 = 5x

x = 10 units

Number of streams:

= 10 units x 1,000

= 10,000 streams

To make a profit of $950,000, the units are:

950,000 = 5x - 50

5x = 950,000 + 50

x = (950,000 + 50) / 5

= 190,010 units

Number of streams is:

= 190,010 x 1,000

= 190,010,000 streams

At what point on the curve x^2 + y^2 = 9 is the tangent line vertical?
Gemiola [76]

x² + y² = 9 is the equation of a circle with center (0, 0) and radius 3.

This puts the vertices at (-3, 0), (3, 0), (0, -3), and (0, 3).

When is the tangent line vertical? <em>when it passes through the x-axis.</em>

Answer: (-3, 0), (3, 0)

ollegr [7]
Using Pythagoras’ theorem a2 + b2 = c2 you can find out the third (longest) side. (6x6) + (8x8) = 100 (the square root of 100 is 10) so ur final sum is 6+8+10 = 24 mm
