You've made a slight error with that second line. You discarded the square root.

The sum of the first n term of a series
is given by:
Sn = 5n^2 - 2n
A sequence U1, U2, U3,........ is
defined by
Ur = Sr - Sr - 1
Express Ur in terms of r in its
simplest form and show that the
sequence is linear (a.p).

Find:
(1) the sum Sn of the of the first n
terms of the sequence whose
rth term is 4 x 2^-r
(ii) the value of n for which the
difference between S and 4 is
less than 10^-4

Good afternoon math guru. I will appreciate if this can solve now. Thanks

Prove that the relation R in the set of non zero integers Io defined by aRb if a^b = b^a for every a,b element of Io is reflexive and symmetry.

By definition, the relation is symmetric, because aRb implies that a^b = b^a which in turn implies that b^a = a^b that is, bra.

Also, R is reflexive because, a^a = a^a, hence aRa.

Can you explain how you came about the answer 24?

Please, help with this question:

A ship 'A' steaming due north at 10 km/hr sight at noon, a second ship 'B' in a direction due east and 1⅔ km away, steaming north east at 8 km/hr. Calculate to the nearest degree the bearing of A from B at 12:15 pm.

Check the algebra I did it in a hurry but I think it should be correct

Re: Nairaland Mathematics Clinic by Abbeycaesar(m): 7:56am On Feb 05, 2022
Well done Sir. The question's from MAN Mathematics for Senior Secondary Schools, Book 2. I arrived at the same answer but the answer at the back of the textbook is different (N60.5°W). That could be a mistake from the author.

MrEDUCATION:
Please, I need explanations to the correct answer.

Let the square root be sqrt(a)-sqrt(b)
Continue with squaring it and equating to the original expression

a-2sqrt(ab)+b=28-10sqrt(3)

collecting like terms, we have
a+b=28................(i)
a=28-b.........(ii)
-2sqt(ab)=-10sqt(3).......(iii)

simplify (iii), ab=75..,.(iv)
sub (ii) into (iv)

you have,
28b-b^2=75
solving the equation, you get b=25 or 3
i.e when b=25, a=3 and vice-versa

hence, your final answer is 5-sqt(3) or sqt(3)-5

X is 40°
AEB =180-(70+60+20)=30°
BDE=90°
X=180-(90+30+20)=40°
You can't use sine rule without any given side.

Your answer is wrong.
Does that look like a right angle to you in your wildest imagination??
A mathematician solved it and solution is attached.

All the angles were solved for.
An when you sum up individual triangles, they ALL give you 180 degrees.

x is 50°

Re: Nairaland Mathematics Clinic by Tradegood: 11:30pm On Apr 13, 2022

Hello house,

Can you kindly help to find x from the diagram?

That is not a 90°

Someone helped out.
All the angles were solved for and when you sum all the angles of all the triangles in the diagram, they all give 180° by the solution below
