Answer and Step-by-step explanation:
So to figure out the Sales tax column, you make the percentage into a decimal. 7.25% into 0.0725
Then multiply 0.0725 by the cost of the item to get the sales tax. For example, 0.0725 * 8 = 0.58

Solution :
Given that the expression is :
This can be written as,
a). Therefore the exponent in the power of 10
= 0
b). Factors of 10 in
= 10 x 10 x 10
= 1000
=
So there are 3 factors of 10 in
c). If we compare the exponent of power of 10 in 1000 and factors of 10 in 1000, then both of them will be same.
But in part a), we are finding exponent in the power of 10 in the expression which is equal to 0. And in part b), we are finding the factor of 10 in 1000, which is equal to 3, as 10 x 10 x 10 = 1000.
d). The value of the expression is 6.
Answer:
Option (2)
Step-by-step explanation:
Given functions are,
c(x) =
d(x) = x + 3
Equation of the composite function will be,
(cd)(x) = c(x) × d(x)
=
=
This function is defined only when denominator is not equal to zero.
(x - 2) ≠ 2
Therefore, for real numbers except x = 2 will be the domain of the composite function.
Option (2) will be the answer.
