17. A golfer takes a swing from a hill twenty feet above the cup

Mathematics
1 answer:
nadya68 [22]3 years ago
4 0

Answer:

The height as a function of time is

h(t) = -(1/2)gt2 + v0t + h0

h(t) = -16t2 + 32t + 20

The ball reaches the ground when h(t) = 0

-16t2 + 32t + 20 = 0

Solve this quadratic equation for t.  You will get a positive solution and a negative solution.  Discard the negative solution, since time begins at t=0 at the moment the ball is struck.  Can you finish from here?

It takes three identical water pumps 8 hours to fill a pool, What is the constant of variation?
BaLLatris [955]

Answer:

Constant of variation is 24.

Step-by-step explanation:

Inverse variation states that a relationship between two variables in which the product is remain constant.

If one variable increases then, the other one decreases in proportion so that the product is unchanged,

if y is inversely proportional to x i.e y \propto\frac{1}{x} or

y =\frac{k}{x} ;where k is the constant of variation.

It is given that 3 identical water pumps takes 8 hours to fill a pool,

since, it will take less time with  more pumps, so it is an inverse variation.

By definition of inverse variation;

time = \frac{k}{pump}

Substitute the values to solve for k;

8 = \frac{k}{3}

Multiply by 3 to both sides we get;

8 \times 3 = \frac{k}{3} \times 3

Simplify:

k = 24

Therefore, the constant of variation is, 24
