CHOICES: a May 15 b. June 1 c. June 15 d. July 1

4.If f(x)= 2x + 5, find f(a + b)

CHOICES: a. 4a-7 b. 2a+2b+5 c. 2a + 5b c.none

5. If 2-i is a zero of P(x)= x^3 - 3x^2 + x + 5, factor P(x) completely

CHOICES:

a. (x+2+i)(x+2-i)(x+1)

b. (x-2+i)(x+2-i)(x+1)

c. (x-2+i)(x-2-i)(x+1)

d. (x-2+i)(x-2-i)(x-1)

Answer 1

1. x^2 = x^3

x = 0, 1

ans: C

.. . .

2. 0.694 * 42 = 29

3. May 15 → 60cm

June 15 → 100cm

thus the middle occurs at the middle .. . .. . that is 80cm will happen on June 1

4 . b

5. c
