Check all conditionals that are a tautology. a. (p → q) v (p → -q) b. (p → q) v (-p → -q) c. (p → q) ^ (p → -q) d. (p → q) ^ (-p → -q) e. (p → q) v (-p → q) f. (p → q) ^ (-p → q)

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
