Answer:

25

Step-by-step explanation:

First you have to understand what f(3) means.

f(x) = x^3 - 2

f(3) means that wherever you see and x, you put in a 3.

f(3) = 3^3 - 2

f(3) = 3*3*3 - 2

f(3) = 27 - 2

f(3) = 25

Answer:

L = 10.20

w = 5.51    Do the doubling before the rounding. The zero is needed in the length.

Step-by-step explanation:

Area = 52 in^2

Area = L * w

L = 2*w

Area = 2w * w = 52

2w^2 = 52                   Divide by 2

w^2 = 26                     Take the square root of both sides

sqrt(w^2) = sqrt(26)

w = 5.5099

L = 10.198

Answer:

It is B

Step-by-step explanation:

[tex] ln(x) + ln(y) - ln(z) [/tex]

from law of logarithms:

[tex]{ \bf{ ln(a) + ln(b) = ln(ab) }} \\ and \\ { \bf{ ln(a) - ln(b) = ln( \frac{a}{b} ) }}[/tex]

so, in the question:

[tex] ln(x) + ln(y) - ln(z) \\ \\ = \{ ln(xy) - ln(z) \} \\ \\ = ln( \frac{xy}{z} ) [/tex]

The required logarithmic expression is ln(xy/z). Option B is correct.

Given that
To simplify ln x + ln y + ln z

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.

A logarithmic function can be defined as the function inverse of the exponential function is a logarithmic function.

In the question, an algebraic expression of the log function is given a simplified form of the expression to be determined using the logarithmic property.

Simplification,
= ln x +ln y + ln z
Since log A  + log B = log(A.B)
and log A - logB = log(A/B)

From above properties
= ln (x . y) - ln z
= ln [(x. y )/z]

Thus, the required logarithmic expression is ln(xy/z). Option B is correct.
