Answer:
D
Step-by-step explanation:
6.8 = (6/5)^x
6.8 = 1.2^x
x ln 1.2 = ln 6.8
x = ln 6.8 / ln 1.2
= 10.513966
Answer: 3.9ft²
Step-by-step explanation:
Find the area of the rectangle first:
= Length * Width
= 2 * 1.5
= 3 ft²
Find the area of the semi-circle by finding the area of a circle and dividing it by 2:
= πr²
= 3.14 * 1.5/2 * 1.5/2
= 1.76625ft²
Divide by 2:
= 1.76625/ 2
= 0.88 ft²
Add the area of the rectangle to the semi-circle:
= 3 + 0.88
= 3.9ft²
The line is y = x also called the diagonal.
If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope
The equation of the graph is given as:
The above equation is a linear equation, which is represented as:
Where m represents the slope of the linear equation.
By comparison, we have:
i.e. the slope of the equation is -0.14
When -0.14 is replaced with 2, the equation becomes
And the slope of the new equation is
2 is greater than -0.14, and 2 is positive.
This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope

Density = mass/volume
the mass is 10578.9 pounds
the volume of a sphere is v = 4/3 πr^3
v = (4/3) (π) (4.3)^3
v = 333.04
10578.9 / 333.04 = 31.76
the final density is 31.76!!
