n+(n+1)+(n+2)+(n+3)=4n+6
4n+6=2(2n+3)
this is a multiple of two so therefore must be even
area of triangle = 1/2 * base * height
area of traingle = 1/2 * 5 * 9
area of traingle = 1/2 * 45
area of triangle = 22.5
triangle * number of triangles that can fit in square will give you the area of the square
it is not shown below?
(i) n(n-1)
If n-1 is odd, then n is even. n(n-1) is the product of an even number and an odd number, so the product is even.
(ii) 2n=2*n Multiplying any whole number by 2 gives an even number, so 2n is an even number. So 2n+1=even number +1=odd number 2n+1 must always be an odd number.
what is it?
what about the index?
√ [ 567 * x^2 * y^4 * z^2]
√567 * √x^2 * √y^4 * √z^2
9 * √7 * √x^2 * √y^4 * √z^2
9 * √7 * x * y^2 * z
9xy^2z√7
(9xy^2z√7)^2
=81x^2y^4z^2*7
Ans:567^4x^8y^16z^8
d is directly proportional to the square of t
d=k*t^2
80=k*4^2
80=k*16
k=80/16
k=5
d=5*t^2
8+4=12
d=5*12^2
d=5*144
d=720m
See u later CPhill
Nevermind I got it.
question 1:
2/n
question 2:
15
no prob
See you soon bro
The Angle Addition Postulate states that: If point B lies in the interior of angle AOC, then. . The postulate describes that putting two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles.
Additive Property of Equality. The formal name for the property of equality that allows one to add the same quantity to both sides of an equation.
So...... yeppers
Nevermind it's definitely C, thanks guys!
Uhh are you sure though?
The answer is 'c' I believe....
Uhh okay i'll try
Here is the image again:
If you can't see that then I can't exactly um post the question, only the answers...
i cant see it post the questions
Never mind it showed up
Thanks Cphill for all the help.
Sorry.....I thought you knew I was being fecitious.
The engine does (3850j - 2250j) of work = 1600 j (or 1600 N-m)
The thermal efficiency is the amount of work produced divided by the heat provided.....
1600j / 3850j x 100% = 41.6 %
Alright sure! Take care CPhill
