Answer:

600

Step-by-step explanation:

p(x) = 1 + 6x - 5x^2

x max = -b/2a

a = -5

b = 6

-6/2(-5) = 6/10 = 3/5 = .6

.6 thousand = 600

600 speakers should be sold.

A Web music store offers two versions of a popular song. The size of the standard version is 2.3 megabytes (MB). The size of the
tamaranim1 [39]

Let x = download size of the standard version.

4515 - x = download size of high quality version.

High quality was downloaded 4 times more so 4 x 4.8 = 19.2 = downloads of high quality versions.

Set up a ratio:

2.3 / 19.2 = x / 4515-x

Cross multiply:

2.3(4515-x) = 19.2x

10384.50 -2.3x = 19.2x

Add 2.3x to both sides:

10384.50 = 21.5x

Divide both sides by 21.5:

X = 10384.50/21.5

X = 483

There were 483 downloads of the standard version.
