Ax+By+C=0. Standard form of a linear equation.
Use C= (B/2)^2. To complete the square.
D=RxT. Distance = (Rate)(Time
y = mx + b. Slope-intercept form ( easy to graph)
Descriptive statistics uses data to provide descriptions of populations. Often this data is represented in the form of tables, charts, graphs, or even just numbers. Here, we organize (visual representation) and analyze data to describe a population.
Inferential statistics utilizes data in such a way that allows us to make predictions, generalizations, and inferences about a population from samples taken. Here, we can compare, predict, and test data in order learn about a population.
Hope this helps.
<h2>
a. What is your equation?</h2>
This is a problem of projectile motion. A projectile is an object you throw with an initial velocity and whose trajectory is determined by the effect of gravitational acceleration. The general equation in this case is described as:

Where:

So:

Finally, the equation is:

<h2>b. How long will it take the rocket to reach its maximum height?</h2>
The rocket will reach the maximum height at the vertex of the parabola described by the equation
. Therefore, our goal is to find
at this point. In math, a parabola is described by the quadratic function:

So the x-coordinate of the vertex can be calculated as:

From our equation:

So:

So the rocket will take its maximum value after 1.99 seconds.
<h2>
c. What is the maximum height the rocket will reach?</h2>
From the previous solution, we know that after 1.99 seconds, the rocket will reach its maximum, so it is obvious that the maximum height is given by
. Thus, we can find this as follows:

So the maximum height the rocket will reach is 66.68ft
<h2>
d. How long is the rocket in the air?</h2>
The rocket is in the air until it hits the ground. This can be found setting
, so:

We can't have negative value of time, so the only correct option is
and rounding to the nearest hundredth we have definitively:

Answer:
We know that 30/25 is 1.2 or 1 1/5. SO if we divide 20 by that then we'll get 16.6667. So I won't give you the answer because its best that you learn to do this yourself because its more beneficial than telling you. What you have left is 16.6667=4x-4. Combine like terms and you'll get your answer. But if your still stuck then you can just let me know and I'll help you as much as I can.
