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]

Find the discount for a stereo that is on sale for 12% off. The
original price is $200.00.
Answer:
$176
Step-by-step explanation:
$200 x 12%
12% --> 0.12
200 x 0.12 = 24 --> discounted off amount
200 - 24 = 176

Answer:
50
Step-by-step explanation:
x=30/0.6 = 50
Answer:
50
Step-by-step explanation:
30÷60=0.5
0.5×100=50
you can reverse it so
50÷100 is 0.5
so 1 percent of 50 is 0.5
so 60 percent of 50 is 30
0.5×60=30

Who is Correct. Please i need help it is for school.
Answer:
neither of them
Step-by-step explanation:
1. To prove that neither of them are correct, we have to work on the equation 2/5(b) + 1 = -11 ourselves.
2. (Solving)
Step 1: Subtract 1 from both sides. (This is where Tyler got it wrong)
[tex]\frac{2}{5}b + 1 - 1 = -11 - 1[/tex] [tex]\frac{2}{5}b = -12[/tex] (this is where Mai got it wrong)Step 2: Multiply both sides by 5/2.
[tex]\frac{2}{5}b * \frac{5}{2} = -12 * \frac{5}{2}[/tex] [tex]b = \frac{-60}{2}[/tex] [tex]b = -30[/tex]Step 3: Check if solution is correct.
[tex]\frac{2}{5}(-30) + 1 = -11[/tex] [tex]\frac{-60}{5} +1 = -11[/tex] [tex]-12 + 1 = -11[/tex] [tex]-11 = -11[/tex]3. As you can see, our solution is correct, but it doesn't match with either Mai or Tyler's works.
Therefore, the answer is neither of them are correct.

$815. Find the amount of each paycheck.
Your coworker's paycheck = $
Your paycheck = $
Answer:
Step-by-step explanation:
100% - 15% = 85% = 0.85
2 × ( 0.85x ) = 815
x = $479.41 ( coworker's paycheck )
479.41 × 0.85 = 407.5
Your paycheck = $407.50

What is the value of this expression? 3(6/8−1/2)+0.25 Enter your answer, in simplest form, in the box.
Answer:
1
Step-by-step explanation:
6/8 - 1/2 can be changed to 6/8 - 4/8
This shows us we have 2/8 or 1/4 left
We then turn 3 into 3/1 for the multiplication
3/1 x 1/4 = 3/4
If we change 0.25 into 1/4 we now have 3/4 + 1/4 (or 0.75 + 0.25)
This gives us a solid answer of 1
