A diver dives from a 10m springboard. the equation f(t) = -4.9t² + 4t + 10 models her height above the pool at time t. When will
Gennadij [26K]

Answer:

At time t = 0.408 sec diver will be at maximum height

Step-by-step explanation:

We have given equation of the height f(t)=-4.9t^2+4t+9

We know that velocity is the rate of change of distance with respect to time

So v=\frac{df(t)}{dt}=\frac{df(-4.9t^2+4t+10)}{dt}=-9.8t+4+0=-9.8t+4

At maximum height velocity will be zero

So -9.8t+4=0

t = 0.408 sec

So at time t = 0.408 sec diver will be at maximum height

Which number is greater 20% or 0.02
mylen [45]
To compare these two values, we need them to be in the same form.  

To convert 20% into a decimal, we divide 20/100, or 0.20.  

When comparing decimals, we know that 0.2 > 0.02. 

Therefore, 20% > 0.02.  (20% is greater than 0.02)
