A. Very Short Questions
Define cardinal number of set.
Fill in the gaps.
i. If n(A) = 50, n(B) = 40 and n(A - B) = 20, then n(AUB) =
n. (A) = n(A) -
iii. n(U)= n(A U B) + ).

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

y= -2x+4, have a great day

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3
