A watermelon is launched from a 25-foot tall platform at a carnival. The watermelon's height h (in feet) at time t seconds can b

Nataly [62]

Answer:

The maximum height of the watermelon is 74 feet.

Step-by-step explanation:

The watermelon reaches its maximum height when its velocity is zero. Mathematically speaking, velocity is the first derivative of the function height, that is:

$v(t) = \frac{d}{dt} h(t)$ (1)

Where $v(t)$ is the velocity, in feet per second.

If we know that $h(t) = -16\cdot t^{2}+56\cdot t +25$ and $v(t) = 0\,\frac{ft}{s}$ , then the time associated with maximum height is:

$v(t) = -32\cdot t +56$ (2)

$-32\cdot t + 56 = 0$

$t = 1.75\,s$

Now we evaluate the function height at time found in the previous step: ( $t = 1.75\,s$ )

$h(t) = -16\cdot t^{2}+56\cdot t +25$

$h(1.75) = 74\,ft$

The maximum height of the watermelon is 74 feet.

The carousel at a local theme park has a diameter of 32 feet. each ride last three minutes and the speed of the carousel is 4.3

Liula [17]

Answer:

1297.37 feet.

Step-by-step explanation:

Given:

The carousel at a local theme park has a diameter of 32 feet.

Each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute.

Question asked:

What is the maximum distance riders travel in one full ride? Round to the nearest hundredth.

Solution:

First of all we will find the radius of the carousel:-

Diameter = 32 feet

Radius, r = $\frac{Diameter}{2} =\frac{32}{2} =16\ feet$

Now, we will find distance covered by the carousel in one ride that means its circumference;

$Circumference\ of \ the \ circle=2\pi r$

$=2\times\frac{22}{7} \times16\\ \\ =\frac{704}{7} \\ \\ =100.571\ feet$

In 1 minute, number of revolution taken by carousel = 4.3

As each ride last for 3 minutes:-

In 3 minutes, number of revolution taken by carousel = 3 $\times$ 4.3 = 12.9

In 1 revolution, distance covered by carousel = 100.571 feet

In 12.9 revolution, distance covered by carousel = 100.571 $\times$ 12.9

= 1297.365 feet

Thus, the maximum distance riders travel in one full ride is 1297.37 feet.
