1. As x approaches 1, f(x) approaches 3-1, that is 2.
If a = 2 and b = 3, f(1) = 2(1)^2 + 3(1) = 5
So there is a 'jump' in values of x at x = 1. So its not continuous at x=1.
2. For continuity at x = 1, ax^2 + bx must = 2 that is when a + b = 2.
3. for continuity at x = 2 , ax^2 + bx must be = 0 that is when a*2^2 + 2b = 0
- that is 4a + 2b = 0.
4. we have system of equations:-
a + b = 2
4a + 2b = 0
this gives a = -2 and b = 4 So f(x) is continuous when a = -2 and b = 4.
First lets simplify both side of this equation.
2 + 7 + ♢ = 3 + 6 + 5
Subtract 9 from both sides of the equation.
9 + ♢ = 14
Answer (C)
♢ = 5
Answer:57
Step-by-step explanation:
Conversion factor is
1 US bushel = 4 US pecks
76 rows x 3 pecks= 228 pecks
228 pecks / 4 = 57
Answer:
Number of bricks require to make the walls
Step-by-step explanation:
The number of bricks needed to make the wall:
= Volume of the wall/volume of one brick
The wall and the brick are in the shape of a cuboid:
Volume of the Cuboid=
For wall:
Volume of the wall=
For one Brick:
Volume of one brick=
Number of bricks required to make the wall:
