Answer:

h(0)=400

The above function value for h(0) shows that height of the ball before it was dropped i.e. at time = 0 seconds.

The height of the ball above the ground before it was dropped = 400 ft.

Step-by-step explanation:

Given:

The quadratic function that models the height of the baseball above the ground in feet , t seconds after it was dropped is given as:

h(t)=-16t^2+400

To find h(0) and interpret the meaning of the function value in contect of the problem.

Solution:

In order to find h(0), we will replace t=0 in the given function as h(t) is a function of time t.

Thus, we have:

h(0)=-16(0)^2+400

h(0)=16(0)+400

h(0)=0+400

h(0)=400  (Answer)

The above function value for h(0) shows that height of the ball before it was dropped i.e. at time = 0 seconds.

The height of the ball above the ground before it was dropped = 400 ft.

Answer:

a ) 2 / n,

b ) 15

Step-by-step explanation:

This is a nice and short question we have here.

Given that a bag has n counters, and that one counter is blue, respectively the rest is red, if two counters are taken at random there isn't a definite percentage that one of the counters chosen is red or blue, but there is a fractional representation of this.

We could express n ( number of counters ) to form a probability of 2 / n. As you can see, two counters are taken at random over n counters, and thus we derived this fraction.

a ) 2 / n

____

Now we have this second part -

2 / n = 2 / 16,\\16 - 1 = 15

Therefore, there are 15 red counters. Hope that helps!
