Step-by-step explanation:
hahahahahaha I finished math I don't want to see that
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.
x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.
Answer:
The amount of money you will receive is $927.419
Step-by-step explanation:
Consider the provided information.
A youth group has a yard sale to raise money for a charity. The group earns $800 but decides to put its money in the bank for a while.
We need to calculate the amount of money if hot bank pays an interest rate of 3% compounded annually, and the youth group leaves the money in for 5 years.
Future value can be calculated as:

Substitute PV=800, r=0.03 and n=5 in above equation.


Hence, the amount of money you will receive is $927.419
Answer:
5%
Step-by-step explanation:
Divide the commission by the selling price of the car:
$500
------------- = 0.05.
$10,000
This 0.05 translates into 5%. That's the commission rate.
