Y=65+40x, i believe this is it im not to sure
The odd one out would have to be 7:41 because 7x6 is 42 which is the pattern thats happening
Answer:
The speed of the plane in still air is 89.83 mph and the speed of air is 8.17 mph.
Step-by-step explanation:
Let the speed of the plane in still air is u mph and the speed of the wind is v mph.
Now, the aircraft flew 490 miles in 5 hours with the wind.
Hence, ........ (1)
Now, the aircraft flew 490 miles in 6 hours against the wind.
So, ............ (2)
Now, adding equations (1) and (2) we get,
2u = 179.67
⇒ u = 89.83 mph
Now, from equation (1) we get,
v = 98 - u = 98 - 89.83 = 8.17 mph.
Therefore, the speed of the plane in still air is 89.83 mph and the speed of air is 8.17 mph. (Answer)
Answer:
10 x 3 = 30 and 10 + 3 = 13
To find the inverse, we need to solve for x in term of f(x)
f(x) = 5x + 4
5x + 4 = f(x)
Solve for x
5x + 4 = f(x)
5x = f(x) - 4
x =
x acts as the invers of f(x), and f(x) is the invers of x, so the inverse function will be
f⁻¹(x) =
