(y-p)^y. (y-p)^y-1. (y-p)^y-2
Answers
Answer:
(2p(p - y - 1) + y^2)) / (y - p)^y.
Step-by-step explanation:
p^2 / (y - p)^y - 2p / (y - p)^y + 1 / (y - p)^y-2
The LCD is (y - p)^y
NOTE : (y - p)^y / (y - p)^y-2 = (y - p)^(y - (y - 2)) = (y - p)^2
So we have
(p^2 - 2p + 1( (y - p)^2) / (y - p)^y
= ( p^2 - 2p +y^2 - 2py + p^2) / (y - p)^2
= (2p^2 - 2py - 2p + y^2) / (y - p)^y
= (2p(p - y - 1) + y^2)) / (y - p)^y.

Alice has 3 pieces of cloth she embroiders different types of designs on each piece of cloth so that each design covers 1/16 of the cloth. How many types of designs can Alice embroider on the three pieces of cloth?
Answers
Answer:
48 designs
Step-by-step explanation:
Total pieces of clothes = 3
Area covered by each design on a piece of cloth = 1/16
How many types of designs can Alice embroider on the three pieces of cloth
Number of designs Alice can embroider on 3 pieces of cloth = Total pieces of cloth / area covered by each embroidery
= 3 ÷ 1/16
= 3 × 16/1
= 48
Therefore, Alice can embroidery 48 types of designs on the 3 pieces of clothes

Given :
The square of a number, x, is 16 less than eight times the number.
To Find :
The value of x .
Solution :
The mathematical equation with all given data is :
[tex]x^2=8x-16\\\\x^2-8x+16=0\\\\x^2-4x-4x+16=0\\\\x(x-4)-4(x-4)=0\\\\(x-4)^2=0\\\\x=4[/tex]
Therefore , the value of x is 4 .
Hence , this is the required solution .
The number is 4.
Given that,
The equation is [tex]x^2 = 8x - 16[/tex]Based on the above information, the calculation is as follows:
[tex]x^2 = 8x - 16\\\\x^2 - 8x + 16 = 0\\\\x^2 -4x - 4x + 16 = 0\\\\x (x - 4) - 4(x - 4) = 0\\\\(x - 4)^2 = 0\\\\x = 4[/tex]

An elevator ascends from rest with an acceleration of 0.6 ms^2 before slowing down with a decelleration of 0.8 ms^2 for the next stop. The total time taken is 10 seconds. Find the distance between the stops. The answer is 17.1 but I dont understand how to get it . Dont answer if you dont know or I will report you.
Answers
I'll be using the following variables and values
t = duration of time from rest to max speed (before it starts to decelerate). This means the other portion of the trip takes 10-t seconds a1 = 0.6 = acceleration when elevator is speeding up a2 = -0.8 = acceleration when elevator is slowing down VS1 = start velocity #1 = 0 = elevator is at rest VF1 = final velocity #1 = final velocity when acceleration process stops VS2 = start velocity #2 = starting velocity when deceleration kicks in VF2 = final velocity #2 = final velocity when deceleration is done = 0 d1 = distance from rest to max speed (acceleration) d2 = distance from max speed to 0 (deceleration)I will also be using the two kinematics equations
Vf = Vi + at x = Vi*t + 0.5*at^2where Vi and Vf are the initial and final velocities respectively, 'a' is the acceleration, t is time, and x is displacement.
----------------------------------------------------------------------------------------------
To start, let's focus on just the accelerating portion of the journey.
The elevator starts at rest, so VS1 = 0. It reaches some current unknown final velocity, but we can calculate that as such
Vf = Vi + at
VF1 = VS1 + a1*t
VF1 = 0 + 0.6*t
VF1 = 0.6t
The elevator reaches a top speed of 0.6t meters per second after traveling and accelerating t seconds.
----------------------------------------------------------------------------------------------
Let's see how much the elevator is displaced after those t seconds (again only focus on the journey where the elevator is speeding up for now)
x = Vi*t + 0.5*at^2
d1 = VS1*t + 0.5*a1*t^2
d1 = 0*t + 0.5*0.6*t^2
d1 = 0.3t^2
The elevator travels 0.3t^2 meters when it is speeding up. We'll use this later.
----------------------------------------------------------------------------------------------
Now onto the portion where the elevator is slowing down.
The starting speed for this portion is VS2 = VF1 = 0.6t because the transition from the last bit of the accelerating portion to the decelerating portion has no gaps. Let's assume it's a smooth transition without any sudden bumps to make the ride uncomfortable.
Let's find the displacement for this portion.
x = Vi*t + 0.5*at^2
d2 = VS2*(10-t) + 0.5*a2*(10-t)^2 .... note the 10-t terms
d2 = 0.6t*(10-t) + 0.5*(-0.8)(100-20t+t^2)
d2 = 6t-0.6t^2 - 40+8t-0.4t^2
d2 = -t^2 + 14t - 40
This is the distance it travels from its top speed, decelerating all the way down to rest.
----------------------------------------------------------------------------------------------
Add the two distances
d = total distance
d = d1+d2
d = ( d1 ) + ( d2 )
d = ( 0.3t^2 ) + ( -t^2 + 14t - 40 )
d = 0.3t^2 - t^2 + 14t - 40
d = -0.7t^2 + 14t - 40
If we knew the value of t (as defined at the very top of this solution), then we could find the total distance traveled.
----------------------------------------------------------------------------------------------
Let's find that value of t.
Recall the following three items
Vf = Vi + at VS2 = VF1 = 0.6t VF2 = 0So,
Vf = Vi + at
VF2 = VS2 + a2*(10-t) ..... note the 10-t portion
0 = 0.6t + (-0.8)(10-t)
0 = 0.6t - 8 + 0.8t
0 = 1.4t - 8
8 = 1.4t
1.4t = 8
t = 8/1.4
t = 5.714 approximately
It takes about 5.714 seconds for the elevator to go from rest to its top speed, before the elevator starts the deceleration process.
----------------------------------------------------------------------------------------------
We can now find the value of d
d = -0.7t^2 + 14t - 40
d = -0.7(5.714)^2 + 14(5.714) - 40
d = 17.1411428
d = 17.1 is the approximate total distance traveled (in meters)
