Chemical Engineering / Q&A, MCQs / Q&AWhich of the following must be done in order to connect data from some data resource to Repeater control ?
A. Call the DataBind method
B. Set the DataSource property
C. Both A and B (Correct)
D. None of these
I. x2 – x – 42 = 0, II. y2 – 17y + 72 = 0 to solve both the equations to find the values of x and y?
II. y2 – 17y + 72 = 0 to solve both the equations to find the values of x and y?
A. If x < y (Correct)
B. If x > y
C. If x ≤ y
D. If x ≥ y
E. If x = y or the relationship between x and y cannot be established.
Explanation:
I. x2 – 7x + 6x – 42 = 0
=> (x – 7)(x + 6) = 0 => x = 7, -6
II. y2 – 8y – 9y + 72 = 0
=> (y – 8)(y – 9) = 0 => y = 8, 9
=> x < y

C. Lower capacity
D. No effect on economy

Mostly bank notes in the world are made of what?
A. Cotton (Correct)
B. Paper
C. Cellulose
D. Wood
