A^2 plus b^2 = c^2
so square 15 and 17, add them, and then do the square root of what you get.
They earned 1800 in the five hours. First you need to multiply 12 by 10 and the 12 by 20 which will equal to 360 all together and then you need to multiply that by 5 which equals 1800.
Answer:


Step-by-step explanation:
Let the speed of faster plane be x
therefore ,
speed of slower plane = x - 20
As the time taken is same ,

therefore ,
faster plane travels at a speed of 190 miles/hr
while..
the slower plane travels at a speed = ( 190-20 ) miles/hr
=> 170 miles/hr

The domain of the function is (-♾️, 1) (1,2]
Let x = 0.9
Let y = 0.6
f(0.9, 0.6) = e(0.9)^2(0.6)
