<span>going downstream - 

t = 14/(2 + v) 

going upstream - 

t = 7/(2 - v) 

14/(2 + v) = 7/(2 - v) 

(2 + v)/2 = 2 - v 

v = 2/3km/h</span><span>

Answer:

C.

discrete data

Step-by-step explanation:

The given function is:

                                                  C(p) = 0.95p

Where p represents the number of bolts purchased. We can calculate the cost based on the number of bolts purchased.

An important distinction between discrete and continuous data is that the continuous data is measured while discrete data is calculated or counted. Since we are obtaining the data by calculation, it must be discrete data.

The function can take on only specific values. For example for p=0, C is 0 and for p=1 the value of C is 0.95. The function cannot take any value in between 0 and 0.95. This is a characteristic of discrete function. A continuous function can take all possible values in an interval.  

Therefore, the answer to this question is: The Function models discrete data.

Answer:

233.19 inch³

Step-by-step explanation:

Volume of prisms: Length * Width * Height

given for first prism: Length = 7 cm  Width = 3.25 cm Height = 7 cm

given for second prism: length = 7 cm width = 3.25 height = 3.25

using the formula:

Total volume: prism 1 volume + prism 2 volume

Total volume: 7 * 3.25 * 7 + 7 * 3.25 * 3.25

                     : 159.25+ 79.9375

                     : 233.1875 inch³

                     : 233.19 inch³ .........rounded to nearest hundredth
