NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by

The sea level is represented by h = 0, therefore, to find the corresponding time when h splashes into the ocean we have to solve for t the following equation:

Using the quadratic formula, the solution for our problem is

The rocket splashes after 26.845 seconds.
The maximum of this function happens at the root of the derivative. Differentiating our function, we have

The root is

Then, the maximum height is

1029.99 meters above sea level.
Answer:
36 degrees for each angle.
Step-by-step explanation:
If you divide 180 by 5 (for each point in the star) you get 36 degrees.
Answer:
--- function
The monthly rate is 10%
Step-by-step explanation:
Given
Let

So, we have:
--- Monday
--- One month later
Required
The function
The function is represented as:
In
, we have:




In
, we have:


Substitute: 

Solve for b


So, the function is:


To calculate the monthly rate (r), we have:

Compare to: 

Make r the subject

Substitute 


Express as percentage


Answer:
30 square millimeters
Step-by-step explanation:
3 x 3 = 9
3 x 1 = 3
there are two sides with the area 9 therefore...
9 x 2 = 18
There are four sides with the area 3 therefore...
3 x 4 = 12
Therefore the suface area is
12 + 18 = 30
He can make a 70 or higher to keep a B avg.
