Let
t = time, hours
h = height, feet
At 1 PM, the time and height are respectively
t₁ = 1 hour
h₁ = 4400 feet
At 4 PM, the time and height are respectively
t₂ = 4 hours
h₂ = 5600 feet
By definition, the mean hourly change in elevation is
Answer: 400 feet per hour
Answer:
You are correct. The answer is 
Step-by-step explanation:
First, we need to plug in our x value to the derviative's equation to find the slope of the line tangent to the graph, f
Now that we have found the slope and have a given point: (-1,6) we can use the point slope formula to find the equation of the line tangent to the graph f.
This problem is an example of ratio and proportion. A ratio is a comparison between two different things. You are given the height and weight of a man at 6 feet and 165 pounds. Also you are given 5 ½ feet. You are required to find the weight of the man at 5 ½ feet. So,<span> </span>
<span>6 feet/165 pounds = 5 ½ feet/ weight </span>
<span>Weight = 5 ½ feet/ (6 feet/165 pounds) </span>
<u>Weight = 151.25 pounds</u>
Answer:
this is the answer
Step-by-step explanation:
hope this will help you
Answer:
Look at the explanation
Step-by-step explanation:
after the second line (4x-2x) +20= 2
--------------
after the 3rd line
2x=2-20=-18
-------------------
after 4th line x=-18/2
-----------------------------------------------------------------------------
At the end
4(-9+5)=2(-9)+2
-36+20=-18+2
-16=-16 so it is right
