Answer:
415.7 mph or mph
Step-by-step explanation:
Did you make a sketch and got a right-angled triangle?
let the horizontal distance between the plane and the station be x miles
let the distance between the plane and the station be y miles
given: dx/dt = 480 mph
find: dy/dt when y = 6
y^2 = x^2 + 3^2
when y = 6
36 = x^2 + 9
x = √27
2y dy/dt = 2x dx/dt
dy/dt = (x/y)dx/dt
= √27(480)/6
= 415.7 mph or 416 mph
i think i hope this helps
Answer:
50
Step-by-step explanation:
If everyone scored 50, the average is just 50.
The math would also be:
50 + 50 + 50 + 50 + 50 / 5 = 250 / 5 = 50
