I need help with questions 1,2, and 3. Would gratefully appreciate it (:

Answer:

Step-by-step explanation:

(2):

First let's organise the data:

33 miles ... x mph ... 4h - downstream

33 miles ... y mph ... 7h - up the stream

x = 33/4 = 8.25 mph

y = 33/7 = 4.71 mph

(3)

P(x) = x^2 - 2x - 3

To find the amount of key rings sold when the profit is 5000$ we have to equate P(x) with 5, because in the problem the profit of the key rings is displayed in terms of thousands.

x^2 - 2x - 3 = 5\\x^2 - 2x - 8 = 0\\x_1 = 4, x_2 = -2

Since the number of keyrings sold has to be positive the only answer is 4 thousand key rings.

A file that is 256 megabytes is being downloaded. If the download is 18.6% complete, how many megabytes have been downloaded? Ro
GenaCL600 [577]
<span>If A file that is 256 megabytes is being downloaded and the download is 18.6% complete, then you just need to multiply the 256 megabytes with 18.6%

The calculation would be: 256 megabytes x 0,186= 47.616 megabytes. 
If you round up the answer to nearest tenth it will be 47.6 megabytes</span>
