I have a problem bringing out the equations here

It t akes a student 12minutes to et to the class from the sporting groung if she waks at 1.5m/s and runs at 3m/s. Had she walked half as far, she should have taken 8minutes. Find the di stance between the school and the classroom.

Pls can i have some help?Thanks in advance

Pls can anyone help indicate a site that has multiple choice questions(mcq) for secondary and high school Maths?I' ll be grateful

I'll like we have a section for wise asayings, be them Mathematical or others.

Ex "A man is not rewarded for having a brain, but for using it".

I'm not very sure of that.

In my opinion I do think (x,y,z) = [z - g(x,y)]/3 is coorect.Since we shall be integrating

S(x+L) is S*(x+L) and not a function, right? Using y as f(x) (as it's easier):

y = S(x+L)/x²

yx² = Sx + SL

yx² - Sx - SL = 0

Using quadratic equation:

x = (S ± √(S² - 4ySL) ) / 2y, y sholud not be 0.

That is ok now, i think

And z/6z=x+yi/6(x+yi).

Rationalise:x+yi(x-yi)/6(x+yi)(x-yi)

= (x^2+y^2)/6(x^2+y^2)

=1/6

NB!!! This is if you saw this under complex numbers.

Pls help me solve for x in 4x^3-3x=1/2. leave answers to 4decimal places. Thanks in Advance

Thanks ery much> I just discovered there's more in Linear Programming than I thought of.

Please LI'll like to know the meaninings of these terms as applied in Linear Programming:

Objective function, Contraints, feasible solution, feasible region, optimal solution, raetest and Least values.

Thanks

Write each equation in the form y=mx+c:

where m is the gradient.

px+4y-2=0

y=-(p/4)x+1/2......., m1=-p/4

2x-y+p=0

y=2x+p.........., m2=2

m1*m2=-1...., (-p/4)*2=-1....p=2

When a polynomial is divided by x-3, the remainder is 3 and when it is divided by x+2, the remainder is 13. Find the remainder when it is divided by(x-3)(x+2)> Hence write out the polynomial.

where the inv of tan:

sin,cos and tan are +ve at 1st quandrant(angle=@°),sin +ve at 2nd(angle=180°-@),tan+ve at 3rd(angle=180°+@°) and cos+ve at 4th(angle=360°-@°).

Invtan(-1/2)=26.6° and Intan(-3°)=71.6°

Therefore required angles are

(180°-26.6)°, (360-26.6)°,(180-71.6)°and(360-71.6)°

Sorry I don't haveagood programthat illustrate Maths symbols.

Thanks for the clues.

How can Basic Algebra be introduced successful to year one students in secondary schools?

Can one start with

3bannanas+4bannanas=7bannanas

3pears+4pears=7pears

In general,3a+4a=7a?
