Step-by-step explanation:
<u>Step 1: Define</u>
Point (5, 5)
Point (5, -8)
<u>Step 2: Identify</u>
(5, 5) → x₁ = 5, y₁ = 5
(5, -8) → x₂ = 5, y₂ = -8
<u>Step 3: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
- Substitute in points [Slope Formula]:

- [Slope] Subtract:

Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.

Answer:
Rate in still water = 27.5 mph
Current's rate = 12.5 mph
Step-by-step explanation:
Let
x mph = row team rate in still water
y mph = current's rate
<u>Upstream:</u>
Distance = 30 miles
Time = 2 hours
Rate = x - y mph
Then

<u>Downstream:</u>
Distance = 30 miles
Time = 45 minutes
hour
Rate = x + y mph
Then

From the first equation:

From the second equation:

Add these two equations:

Subtract these two equations:

Answer:
51*pi or 160.221
Step-by-step explanation:
total volume = volume of a cone + volume of a cylinder
total volume = 1/3* pi*r^2* height(of cone) + pi* r^2 *height(of cylinder)
total volume = 1/3 * pi * 3^2 * 5 + pi * 3^2 * 4
total volume = 51*pi = 160.221
