Step-by-step explanation:
Answer:
irrational number
Step-by-step explanation:
Irrational numbers are not repeating or terminating.
These type of numbers are called irrational numbers.
So it is an irrational number
Just graph it... Firstly though, do you know what a function is?
Google linear function, parabolic function, exponential function etc. to get familiar with what a function looks like.
Firstly, no function that I know has
(4, 5) and (4, -4) where there are two y coordinates for 1 x coordinate.
It is not linear, parabolic, or exponential, it could be some other type of function. But assuming you're in high school i'd say its safe to bet the answer is FALSE.
Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)
1134.6x + 30634.2 = 1469.4x - 39673.8
334.8x = 70308
x = 210 mph
