Answer:

Step-by-step explanation:
By definition, we can write ln instead of log. WHEN??
Whenever the base of the logarithm is the number "e".
Hence, when we have:

We can write it in shortcut as:

Hence, ln x can also be written as 
Fourth answer choice is right.
Answer:
- Population: Soil around a former waste dump
- Parameter: Concentrations of toxic chemicals
- Sample frame: Accessible soil around dump
- Sample: 16 soil samples
- Method: Unclear
- Bias: Uncertain if soil samples were randomly chosen
Step-by-step explanation:
The above answer explanation can be more clear by understanding that the population is the soil around the former waste dump and the samples are 16 which were taken from EPA.In report, the method is unclear too.
Answer:
Side length and perimeter of 1 face
Area of 1 face and surface area
Step-by-step explanation:
Suppose you are given cube with side length of x units.
Then
Side length = x units
Perimeter = 4x units
Area of 1 face
square units
Surface area
square units
Volume
cubic units
A linear relationship is any equation that, when graphed, gives you a straight line.
Consider all options:
A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function
is a straight line.
B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation
.
C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation
.
D. Area of 1 face and surface area is a linear relationship, because the graph of the function
is a straight line.
E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation
.
Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle. The height from the ground to the top of the ramp 6. 0 ft. Option D is correct.
<h3>What is the Pythagoras theorem?</h3>
Pythagoras theorem is a basic relationship in geometry between the three sides of a right triangle.
It indicates that the area of the hypotenuse square is equal to the sum of the areas of the squares on the other two sides.
The given data in the problem will be;
L is the length of ramp= 10 feet
x is the horizontal distance from the bottom of the ramp = 8 feet
h is the height from the ground to the top of the ramp=?
According to Pythagoras theorem,

Hence the height from the ground to the top of the ramp 6. 0 ft. Option D is correct.
