Answer:

3

Step-by-step explanation:

the initial statement is  

y ∝ 1 /x

 to convert to an equation multiply by k the constant

of variation

y = k × 1 /x = k /x

to find k use the given condition

y = 5  when  x = 6

y = k/ x ⇒ k = y x = 5 × 6 = 30

y = 30 /x

when  

x = 10

then

y = 30 /10 = 3

Answer: y = 3

Step-by-step explanation:

In inverse variation, as one variable increases, the other variable decreases and as one variable decreases, the other increases.

We would introduce a constant of proportionality, k. Therefore,

y = k/x

When y = 5 , x = 6

Therefore,

5 = k/6

Cross multiplying by 6, it becomes

k = 6 × 5 = 30

The expression becomes

y = 30/x

Therefore, when x is 10,

y = 30/10

y = 3

A person standing close to the edge on the top of a 400-ft building drops a baseball. The quadratic function h left parenthesis
swat32

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.
