Agolf ball，thrown upwards ，rises at a speed of v metres per second the ball reaches a maximum height of h metres. h is proportional to the square of v.
when v =20, h=8
work out the maximum height reached by the golf ball when v =35

24.5m

Step-by-step explanation:

given h is proportional to v² or

h ∝ v²

we can write this in terms of constant k

h = kv²

given h = 8 when v = 20

h = kv²

8 = k 20²

8 = 400k

k = 8/400 = 0.02

hence our equation becomes

h = 0.02v²

when v = 35

h = 0.02 (35²)

h = 24.5 meters

answer: i guess 5 units?

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
