Y(-2) = 3 (x - 4)
Y = 3 (-2 - 4)
Y = 6 + 12
Y= 18
Answer:
2.72 hours
Step-by-step explanation:
Data provided:
Time taken by Huck Finn to paint the fence = 5 hours
Time taken by Tom to paint the fence = 6 hours
Now,
Fence painted in 1 hour by Huck Finn =
of total fence
and,
Fence painted in 1 hour by Tom =
of total fence
Therefore,
Total fence painted together by Huck and Tom in 1 hour =
+![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
or
Total fence painted together by Huck and Tom in 1 hour = ![\frac{5+6}{5\times6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2B6%7D%7B5%5Ctimes6%7D)
or
Total fence painted together by Huck and Tom in 1 hour = ![\frac{11}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B30%7D)
Hence,
Time taken by Huck and Tom to together paint the fence = ![\frac{1}{\frac{11}{30}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Cfrac%7B11%7D%7B30%7D%7D)
= 2.72 hours
The answer is positive 13
Hello,
x²-16x+y²+6y+53=0
==>x²-2*8*x+8² + y²+2*3*y+3²+53-64-9=0
==>(x-8)²+(y+3)²=20
Center is (8,-3) and radius =√20
348
Multiply by 180/pi
As a check: 2pi equals 360 degrees and your almost at 2pi
