Answer:

Option c - The domain of the logarithmic function f(x)=\log_5x  is all positive real numbers.

Step-by-step explanation:

Given : Following statements.

To find : Which of the following is true?

Solution :

a. The base of a logarithmic function can be a negative number.

False, because the base of a logarithmic function is greater than 1.

b. A logarithmic function is the inverse of a rational function.

False, because the inverse of the logarithmic function is an exponential function.

c. The domain of the logarithmic function f(x)=\log_5x  is all positive real numbers.

True, because the domain of the logarithmic function  y=\log_bx  is the set of positive real numbers and the range is the set of real numbers.

d. The base of a logarithmic function can be zero.

False, because the base to zero is when solved by exponent then it became 0 to the power which is always zero.

Therefore, Option c is true.

How do i do this ???
Westkost [7]

a peculiar thing about the centroid of a triangle, is that it cuts all the medians in a 2:1 ratio, so JP : PM are on a 2:1 ratio, thus

\bf JP:PM\qquad 2:1\qquad \cfrac{JP}{PM}=\cfrac{2}{1}\implies \cfrac{27}{PM}=\cfrac{2}{1}\implies \cfrac{27}{2}=PM\\\\-------------------------------\\\\JM=JP+PM\implies JM=27+\cfrac{27}{2}\implies JM=\cfrac{54+27}{2}\\\\\\JM=\cfrac{81}{2}\implies JM=40\frac{1}{2}

briana house is at (1,6) and jordan house is(5,3) what is one possible path from brianna house to jordan house
Maurinko [17]

Answer:

see the explanation

Step-by-step explanation:

Let

A (1,6)------> location Brianna's house on a map

B (5,3)------> location Jordan's house on a map

we know that

One possible path from Brianna's house to Jordan's house it's a straight line  ( the shortest distance)

using a graph tool

see the attached figure

<em>Find the distance points AB</em>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the values

d_A_B=\sqrt{(3-6)^{2}+(5-1)^{2}}

d_A_B=\sqrt{(-3)^{2}+(4)^{2}}

d_A_B=\sqrt{25}

d_A_B=5\ units

The distance from Brianna's house to Jordan's house is 5 units
