How many integer points lie within area bounded by x = |7| and y = |9| ?
In a trapezium, it was found that the sum of the squares of the diagonals is less than the sum of the squares
of the sides by 144 cm2. If the shorter of the parallel sides is 9 cm long, then find the length of the longer of
the parallel sides (in cm).

If x, y, z are the angles (in degrees) of the triangle ABC, where x, y, z are integers, then what is the number of
values that (x - y - z) can take?
90, 179, 178, 177
but i am getting 179x178/2
plz explain
Seven students - A, B, C, D, E, F and G calculated the sum of the marks of six students of their class. The following are the statements made by them.
A: Five of them scored a total of 32 marks
B: Five of them scored a total of 35 marks
C: Five of them scored a total of 37 marks
D: Five of them scored a total of 31 marks
E: Five of them scored a total of 36 marks
F: Five of them scored a total of 34 marks
G: Five of them scored a total of 33 marks
During the calculation, exactly one of them made a mistake in adding the marks.
1.Which student made the mistake in adding the marks?
a) D (b) E (c)F (d) NOne of these
2.What is the highest marks of any student among the six students?
(a) 8 (b)9 (c)10 (d)11
please solve this question and provide explanation....
if 2f(x)-3f(1/x)=x^2 (xi s not equal to 0) then f(2) is equal to
-7/4
5/2
-1
NOT
The sides of triangle ABC are a cm, b cm and c cm. The sides of triangle DEF are d cm, e cm and f cm. And
a (a + b + c) = d2 ; b (a + b + c) = e2 ; c (a + b + c) = f2; Then triangle DEF is
acute, obtuse, right angled or isoceles
I think it was in AIMCAT
If f(x)=log (1+x/1-x) then f(2x/1+x^2) is equal to
(f(x))^2
(f(x))^3
2f(x)
3f(x)
Which SIMCAT (Unproctored) should I prefer now....I have my D-Day on 5th Nov.
If x is not equal to 1 and f(x) = x+1/x-1 is a real function then f(f(f(2))) is
1
2
3
4
If 4f(1-x)-5f(x)= x^2+1..then f(3)?
