The vertex of a parabola occurs at 
.
Let's find 
first.
Now we can obtain 
which is 
in this case:
.
The vertex is (-1,-6).
Cf=cold faucet rate
hf=hot faucet rate
cf*18min=1 tub
(cf+hf)*8min=1 tub
cf+hf=1tub/8min
cf=1tub/18min
hf=(1/8-1/18)tubs per minute
hf=5/72
It takes 14.4 minutes.
This question uses a dotplot graph from which you have to extract the information.
I have attached the dotplot graph in a pdf file. You can open the file to see the graph if you do not have it.
The graph shows with dots (they use this mark +) the 51 states. Every dot means that one state has the number of license drivers per 1000 residents given by the line. For example, you can see that just above the mark of 700 therer are two dots, meaning that two states have 700 licensed drivers per 1000 residents.
Now you can see that there are 5 dots "close" the 800 mark.
That means that 5 out of 51 states "seem to have close to 800 licensed drivers per 1000 residents".
The percentage is calculated as [5/51]*100 = 9.804 %, which rounded to one decimal place is 9.8%.
Answer: 9.8%
Answer:
14/3a²
Step-by-step explanation:
-6a × 7/-9a³
(7 × 6a) / 9a³
42a / 9a³
14a / 3a³
14/3a²
X=5.4 and Y=10.5.
Used the law of cosine equation, then SOHCAHTOA, and then Pythagorean theorem.
