Answer:
t = 8/5
Step-by-step explanation:
I'm assuming the equation given is the velocity of the particle
Derive the equation
[tex]5t^4 - 8t^3[/tex]
Set it equal to 0 & solve for t
[tex]0 = 5t^4 - 8t^3\\8t^3 = 5t^4\\8 = 5t\\\frac{8}{5} = t[/tex]
The value of time at which acceleration is zero is required.
The required value of [tex]t=1.2\ \text{s}[/tex]
The function of motion is
[tex]s=(t)^5-2t^4[/tex]
Differentiating with time we get velocity
[tex]s'=5t^4-8t^3[/tex]
Again differentiating with time we get acceleration
[tex]s''=20t^3-24t^2[/tex]
Now acceleration [tex]s''=0[/tex]
[tex]0=20t^3-24t^2\\\Rightarrow 20t^3=24t^2\\\Rightarrow t=\dfrac{24}{20}\\\Rightarrow t=1.2\ \text{s}[/tex]

If the area of a circle measures 25 pi cm², what is the circumference of the circle in terms of pi?
Answer:
10π cm
Step-by-step explanation:
Given
Area of the circle=25π cm^2
Solution
πr^2=25π
r^2=25
r=√25
r=5
So circumference of the circle=2πr
=2π×5
=10π cm
So the answer is 10π cm

A man, a woman, and their four children randomly stand in a row for a family picture. What is the probability that the parents will be standing next to each other?
Answer:
Required probability = 2 / 11
Step-by-step explanation:
Sample space of 5 person = 11!
One woman one man arrangement = 2!
Arrangement without woman = 10!
Required probability = [2!][10!] / [11!]
Required probability = 2 / 11
The probability that the parents will be standing next to each other is 2/11
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Sample spaceGiven a woman, man and their four children, if their parents will be standing next to each other, that makes it 5 people. The sample space for 5 people is 11!
The parent arrangement is 2!If they are arranged without the woman, the expected event will be 10!Pr(parents standing next to each other) = 2!10!/11!
Pr(parents standing next to each other) = 2*10!/11*10!
Pr(parents standing next to each other) = 2/11
Therefore the probability that the parents will be standing next to each other is 2/11

The price of a new computer is $1,449 at your local store. This is 18% less than what it costs at the Brownstone Mall. How much should it cost at the Brownstone Mall?
Given:
Price of new computer at local store = $1,449
This is 18% less than what it costs at the Brownstone Mall.
To find:
The cost of new computer at the Brownstone Mall.
Solution:
Let x be the cost of new computer at the Brownstone Mall.
According to the question,
[tex]x-18\%\text{ of }x=1449[/tex]
[tex]x-\dfrac{18}{100}x=1449[/tex]
[tex]x-0.18x=1449[/tex]
[tex]0.82x=1449[/tex]
Divide both sides by 0.82.
[tex]x=\dfrac{1449}{0.82}[/tex]
[tex]x=1767.07317[/tex]
[tex]x\approx 1767.07[/tex]
Therefore, the cost of new computer at the Brownstone Mall is $1767.07.
