Answer:
So, how do we check to see if two functions are inverses of each other? Well, we learned before that we can look at the graphs.
Step-by-step explanation:
Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
We are basically given most of what we need to calculate the height of the cannonball.
We use the formula h = –16t+ vt + s to find the height requested.
Let v = 160
Let s = 10
Let t = time in seconds
Was the value of t included? We need to know t to plug into our formula.
You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.
Answer:
<u><em>1</em></u>
Step-by-step explanation:
That's like asking "What's the dollar amount of one half ?"
"Half" is not an amount. It's half of some amount that's been
previously described.
8.15% isn't an amount of anything.
It's 0.0815 of some amount that's already been described.
Answer:
(-2,0)
Step-by-step explanation:
We can just use the formula for finding the midpoint, as shown below:
So i.e. we just take the average of the two x-coordinates, and similarly, the average of the two y-coordinates.
This gives:
midpoint = ((2+ -6)/2 , (10 +-10)/2)
= (-2, 0)
