Pls rest brotherly,but always remember u are the realest MVP

I stit dey learn I don solve two more on paper make I quickly type am

The equation is y =mx + c m is the slope = tan 135 = tan45=-1 (y - y¹)/(x - x¹) = m (y-3)/(x-2)=-1 y - 3 = -(x - 2) y-3=-x+2 y+x=2+3 x+y=5

you can do justice to the fraction question by applying the rules of bodmas or better still use the calculator

Thank you very much sir, I still have more tho

sir? I'm a very young boy.post the questions,I will try to solve them if I can.

Increase in radius dr/dt = 0.5
Area of the circular disc = πr
Increase in area: dA/dr = 2πr
Rate of increase in area: dA/dt = dA/dr * dr/dt
when r = 6cm
= 2πr * 0.5
= 2 * π * 6 * 0.5
2 * π * 6 * / = 6 π cm /s

Wow,I had no idea there was a thread like this,I need someone to solve these questions

1.nth term =3^(n-1)
1st term =3^(1-1)=3°=1

number of sides =12
each angle=1800/12=150°

Derive the rules of pascal triangle and solve this using pascal triangle and correct to 2d.p
(1.01)4

(a+b)⁴=a⁴+4a³b+6a²b²+4ab³+b⁴
(1.01)=(1+0.01)
1=a
0.01=b
(1.01)⁴=1⁴+4(1³)(0.01)+6(1²)(0.01)²+4(1)(0.01)³+(0.01)⁴
will modify this later, I'm typing on the road

mathefaro:
what I meant was that. It is not really correct to say
e^ln = 1
There has to be an argument to the log function.

you are right

mathefaro:
Fixed e^x and lnx are the inverses of each other

yeah In(e^x)=e^(Inx)

Fixed e^x and lnx are the inverses of each other

Solve for X anyone. I have already given the answer, but solve to get it.
Lets see how good you are

x^(1/√x)=2
applying natural log
In(x^(1/√x)=In2
(1/√x)Inx=In2
(x^-1/2)Inx=In2
since e^In=1
(e^In(x^-1/2)Inx=In2
(e^-1/2Inx)Inx=In2
multiplying both sides by -1/2
(e^-1/2Inx)(Inx*-1/2)=(-1/2)(In2)
(e^-1/2Inx)(-1/2Inx)=-1/(2In2)
since. W(xe^x)=x
adding W to both sides
-1/2Inx=W(-1/(2In2))
multiplying by -2
Inx=-2W(-1/(2In2)
e^Inx=e^-2W(-1/(2In2)
x=e^-2W((-1/2In2))
x will have 4 solutions including 2 complex solutions
don't have the Wolfram alpha but I'm sure x=4

ReignDigitals:
The best app to download for android is Qpython3. Its a python IDE developed by jet brains. It will help you understand python codes on your phone.
To start with python, run this example on your phone.

name = input("What is your name: ?" )
print("Hello", name)

Run the above example code on your Qpython3 and save it test.py

thanks boss, I'm using both pydroid3 and qpython 3l

randomShek:
Download SoloLearn and use the book “Automate the boring stuff with python”

If you use them side by side while completing the exercises in both, you’ll be fine

thanks boss, I'm really grateful

Najdorf:
Pydroid is much better than Qpython but they both can get the job done.

I'll suggest imo one of the best books for learning python

Python Programming for the Absolute Beginner 3 by Mike Dawson

You can get it at www.b-ok.xyz.

alright boss,I have both.Thanks
