What is the domain of f(x)= 3squareroot x?

Mathematics

Vinvika [58]3 years ago

Answer:  Domain: x ≥ 0    Interval Notation: x = [0, ∞)

<u>Step-by-step explanation:</u>

f(x) = 3√x

There IS a restriction on x because it is inside the square root symbol.

In order for the radical to be a real number, the expression under the radical must be greater than or equal to 0. The value inside the radical is "x".

So, x ≥ 0       <em> It is already solved for x so no further work is needed.</em>

A cat falls out of a tree and takes 1.4 seconds to land safely on its paws on the ground how many meters did the cat fall ?
lutik1710 [3]
To solve this, we are going to use the distance of a free fallen object: d=0.5gt^2
where
d is the distance 
g is the gravity of the Earth 9.8m/s^2
t is the time in seconds 

We know form our problem that a cat falls out of a tree and takes 1.4 seconds to land, t=1.4. Lets replace that value in our formula to find d:
d=0.5gt^2
d=0.5(9.8)(1.4)^2
d=9.604 meters 

We can conclude that the cat fell a distance of 9.604 meters.

#!). Two planes leave New York at 10am, One heading for Europe at 600mph and one heading in the opposite direction at 150mph. At
timurjin [86]

Speed = Distance / time

Distance = Speed x time

In t hours, first plane travels = 600 t miles

In t hours, the second plane travels =150 t miles

After t hours the distance between the two planes is:

(600t+150t)= 750t ( since both travel in opposite directions)

When the distance is 900 miles:

750t= 900

Solve for t:

t= 900/750

t= 1.2 hours

After 1.2 hours.

1.2 x 60 = 72 minutes = 60 +12 = 1 hour and 12 minutes

Since both leave at 10 pm:

10am + 1 hour and 12 minutes : 11:12 am

They will be 900 miles apart at 11:12 am

Each one traveled:

Plane 1:

Distance: Speed x time = 600 mph x 1.2 = 720 miles

Plane 2:

Distance = Speed x time = 150 mph x 1.2 = 180 miles
