Find the coordinate of the midpoint of GH with endpoints G(-5,4) and H (-5,8)
Yuri [45]

Answer:

(-5,6)

Step-by-step explanation:

G(-5,4)=(x1,y1)

H(-5,8)=(x2, y2)

midpoint=?

now,

(x,y)= x1+x2/2     y1+y2/2

         -5-5/2        4+8/2

           -10/2          12/2

             -5              6

therefore the co ordinates of midpoint are(-5,6)

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
