A raindrop falls at 200m per minute. how long will it take a raindrop to travel 6000m?
Kryger [21]
The first thing you should know is that by definition:
 d = v * t
 Where
 d: distance
 v: speed
 t: time
 We then have to clear the time:
 t = (d) / (v)
 Substituting the values:
 t = (6000) / (200)
 t = 30 minutes
 Answer: 
 It will take a raindrop to travel 6000m about: 
 t = 30 minutes

Find the area of a circle whose circumference is 18.84.
ivann1987 [24]

Answer:

310.23

Step-by-step explanation:

circumference is radius * 2

to get radius from circumference, divide circumference by 2

18.84 / 2 =9.42

area for circle:

pi * r^2

3.14 * 9.94^2

3.14 * 98.8

3. A model rocket is launched from the ground with an initial velocity of 352 ft/sec.
Hoochie [10]

Answer:

e. It will take 11 seconds to reach the maximum height of 1,936 feet.

f. It will take 22 seconds to return to the earth.

Step-by-step explanation:

Given:

Initial velocity v_0 = 352 ft/sec

Solving for question e.

To find the time required to reach the maximum height we will use the formula,

h(t) = -16t^2+v_0t+h_0,

where v_0 is the starting velocity

h_0 is the initial height.

Using the velocity and starting height from our problem we have,

h(t) = -16t^2+352t+0,

The path of this rocket will be a downward facing parabola, so there will be a maximum.

This maximum will be at the vertex of the graph.

To find the vertex we start out with x= \frac{-b}{2a} which in our case is,

x=\frac{-352}{2(-16)}=\frac{-352}{-32}= 11

So, It will take 11 seconds for the rocket to reach its maximum height.

We will find maximum height using the formula by substituting value of t we get,

h(11)=-16(11^2)+352(11)+0\\h(11) = -16 \times121+ 352 \times 11 = -1936+3872= 1936 \ ft

Hence the maximum height will be 1936 \ ft

Now Solving for question f.

To find the time required for rocket to reach earth.

We will set our formula to 0 to find the time.

0= -16t^2+352t+0\\-16t(t-22)=0

Using the zero product property, we know that either -16t = 0 or t - 22 = 0.  When -16t = 0 is at t = 0, when the rocket is launched. t - 22 = 0 gives us an answer of t = 22.

So the rocket reaches the Earth again at 22 seconds.
