We have to find the number of significant figures in the product of 1.6 cm and 2.4 cm.
Let us first find the product of 1.6 cm and 2.4 cm.
= 3.84 square cm.
Now, we have to determine the number of significant figures in 3.84
The significant digits of a number are the digits have meaning or they contribute to the value of the number. All non-zero digits are significant
, any zeros between significant digits are also significant figures and the trailing zeros to the right of a decimal point are significant figures.
Therefore, in 3.84, there are 3 significant figures in this number.
So, there are 3 significant figures in the product of 1.6 cm and 2.4 cm.
Answer:
(a) 4.148 x 10^(12) ways
(b) 5,827,360 ways
Step-by-step explanation:
Number of Demonstrators (D) = 44
Number of Repudiators (R) = 56
(a)
5 senate members must be Repudiators and 5 must be demonstrators, assuming that the order at which they are selected is irrelevant:
(b)
Since there are two different positions, (speaker and vice speaker), order is important in this situation, and the total number of ways to select two senators from each party is:
Log5(x)+log5(4x-1)
As the bases are the same the number doesn't matter
Log (a) + log(b) =log (ab)
Log(4x^2-x)
(x )(4x-1)
x=0.25 or x=0
Log(4×0.25^2-0.25) = log(0) = Infinity
Same with 0. So no answer

5
