Part A
Suppose a rocket is being launched into outer space. On its way up, several different forces act on the rocket. One of these forces, thrust, is
applied by the rocket's engines.
The rocket's engines apply a constant upward force to a rocket on its way to outer space. In the absence of other forces, the upward force on the
rocket would cause it to accelerate up at a constant rate of a meters/second.
Still ignoring any other forces, the height of the rocket can be expressed as a function of the time elapsed in seconds after the launch, t. This
function, ft), is equal to half the product of the rocket's acceleration and the square of the time after launch. Write the equation for ft).
The speed of the rocket is able to increase with time in the upward
direction because the rocket has an upward acceleration.
[tex]\displaystyle \mathrm{The \ function \ that \ gives \ the \ height \ of \ the rocket \ is \ }\underline{f(t) = \frac{1}{2} \cdot a \cdot t^2}[/tex]Reasons:
The acceleration of the rocket = a
According to Newton's Law of motion, the height reached by the rocket with time can be found by the formula;
[tex]\displaystyle f(t) = u \cdot t - \frac{1}{2} \cdot a \cdot t^2[/tex]
Where;
u = The initial velocity of the rocket = 0
Which gives;
[tex]\displaystyle f(t) = 0 \times t - \frac{1}{2} \cdot a \cdot t^2 = \mathbf{ \frac{1}{2} \cdot a \cdot t^2}[/tex]

Please help with my portfolio question. I have to select the slope per equation
Try this option, all the details are in the attachment.
Answer:
like 1 - y=-5x + 10
line 2 - y=2x + 4
line 3 - y=4x + 3
line 4 - y=8
Step-by-step explanation:
y = mx + b means y equals the slope times x, plus the y intercept, in this case they all had different y intercepts so you just had to look and where the line touches the y axis

Domain (value of x) is any real value except x=13 or x=−25
The domain is the value of x in the function.
Here the denominator must not be zero.
What is the domain?
The domain of a function is the set of inputs accepted by the function.
6x^2+13x−5≠0
or 6x^2+15x−2x−5≠0
or 3x(2x+5)−1(2x+5)≠0

An airplane starts to descend from an altitude over 30,000 feet at what rate is the airplane descending?
Answer:
20,000 feet
Step-by-step explanation:
Based on the initial altitude and the rate that the plane is descending, the relevant equation is = 30,000 - 2,000x. The altitude after 5 minutes is 20,000 feet above sea level.
The plane begins at 30,000 feet above ground and is descending at 2,000 feet per minute. The relevant equation after x minutes is:
= Initial altitude - (Descent in feet per minute x Number of minutes)
Plugging in the values gives:
= 30,000 - (2,000 × x)
= 30,000 - 2,000x
