Sea World has 9 aquariums with small fish in them and the number of fish in each tank are shown below: 45, 10, 48, 19, 36, 25, 6

crimeas [40]

Answer:

Step-by-step explanation:

To find the range, subtract the lowest number from the highest number

Arrange the numbers from least to greatest

45, 10, 48, 19, 36, 25, 63, 14, 37

10, 14, 19, 25, 36, 37, 45, 48, 63

The highest number is 63, and the lowest is 10

Now, subtract the lowest (10) from the highest (63)

highest - lowest

63-10

So, the range of the number of fish is 53

A ball, thrown vertically upwards, from the ground, has its height h (in meters) expressed as a function of time t (in seconds),

Over [174]

Answer:

a. 15 meters.

b. 20 meters.

Step-by-step explanation:

a. The height of the ball at 3 seconds. 20 * 3 - 5 * (3)^2 = 60 - 5 * 9 = 60 - 45 = 15.

The ball will be 15 meters high.

b. The maximum height reached by the ball.

To get that, we need to find the vertex of the parabola. We do so by doing -b/2a to find the x-coordinate of the vertex.

In this case, a = -5 and b = 20.

-20 / 2(-5) = -20 / -10 = 20 / 10 = 2.

Then, we find the y-coordinate by putting 2 where it says "t".

h(2) = 20(2) - 5(2)^2 = (40) - 5(4) = 40 - 20 = 20 meters.

Hope this helps!
