Answer:
( 2x - 1 ) ( x + 3) / ( 2x - 3 ) ( x + 1 )
Step-by-step explanation:
(x - 2) / (x + 1) - 3(1 - 4x) / ( 2x - 3 ) ( x + 1 )
{ ( x - 2 ) ( 2x - 3) - 3 ( 1- 4x) } / ( 2x - 3 ) ( x + 1 )
{ 2x^2 - 7x - 3 + 12x} / ( 2x - 3 ) ( x + 1 )
{ 2x^2 + 5x - 3 } / ( 2x - 3 ) ( x + 1 )
( 2x - 1 ) ( x + 3 ) / ( 2x - 3 ) ( x + 1 )
Answer:
1 4/5
Step-by-step explanation:
Answer:
Step-by-step explanation:
first term = a = 352
Common difference = d = second term - first term
= 345 - 352
= (-7)
nth term = a + (n-1)*d
43rd term = 352 + (43-1)*(-7)
= 352 + 42 *(-7)
= 352 - 294
= 58
Answer:
C) {(3, 4), (3, 5)}
Step-by-step explanation:
We know that,
<em>'Function is a relation in which every element of the domain is mapped to a unique element in the co-domain'.</em>
So, we get that,
<em>In the ordered pair (x,y), the if 'x' is mapped to two values say y and z, then for the relation to be a function, y must be equal to z.</em>
So, according to the options, we see that,
In option C i.e. the relation {(3,4), (3.5)}, we have that, 3 does not have unique image i.e. it is mapped to 4 and 5 both.
Thus, this relation does not satisfy the definition of a function.
So, option C will not represent a function.
V (cone) = (1÷3) × (r×r×h) л cm3
3 cone = 1 cylinder (if "h" and "r" is same)
There is two cone...
1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3
2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3
15 + 24 = 39л cm3
