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]

Your weekly paycheck is 15 percent less than your coworker's. Your two paychecks total
$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
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
Tom has 28 milk chocolates and Emily has 24 dark chocolates. They have to divide these chocolates into small packets that each have the same
number of dark chocolates and the same number of milk chocolates. They also want to use all of the chocolates,
The maximum number of packets they can make is
To make the maximum number of packets, each packet should have
milk chocolates and
dark chocolates
Answer:
The answer is 4.
Step-by-step explanation:
Answer:
4 milk chocolatero need to be removed to have even amounts
24+24= 48
24 packets with 1 of each(2 count) is one possibility.
You can have less packets with more chocolates inside like 12 packets with 4 count(2 of each)
Any combination with result 48. To use al chocolatesl : 4 packets:Each packet has 6dark and 7milk choc

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.

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
