We are given a circle with a diameter of 72 ft. We are asked to determine its area. To do that we will use the following formula:
[tex]A=\frac{\pi D^2}{4}[/tex]Where "D" is the diameter. Replacing the values:
[tex]A=\frac{(3.14)(72ft)^2}{4}[/tex]Solving the operations:

For an angle a in the fourth quadrant, the reference angle is given by:
360º - a
The angles in the fourth quadrant are those between 270º and 360º. So, 342º is in the fourth quadrant, and its reference angle is:
360º - 342º = 18º
Therefore, the third option is correct.

A plane has one dimension, length A line has a define begging and end A plane consists of an infinite set of lines. A line consists of an infinite set of points
Explanation:
Question:
What statements are true regarding undefine terms in geometry
A point has no length or width.
This is true because a point cannot have a dimension
A plane consists of an infinite set of lines.
This is not true because from the definition of a plane, it must have an infinite set of lines or points.
A plane has one dimension, length
This statement is not true because a line is a one dimensional object and as such can only have one dimension which is its' length.
A point indicates a location in a coordinate plane.
This statement is true because any point located on a plane must have an ordered pair of an x and y coordinate
A line has a define begging and end
This is not true because A distance along a line must have no beginning or end.
A line consists of an infinite set of points
This is not true becaue a plane consists of an infinite set of points
Hence,
The final answers are
A point indicates a location in a coordinate plane.
A point has no length or width.

The value of k associated to the cubic equation f(x) = x³ + k · x + 5 is equal to - 6.
What is the value of k of a cubic equation?
In this question we have a cubic equation of the form f(x) = x³ + k · x + 5 and we need to determine the value of k such that the binomial x + 1 is a factor of f(x). A value of x is a factor of the polynomial if and only if the following expression is observed:
f(x) = 0, for x = a
If we know that x = 1 and f(1) = 0, then the value of k is:
1³ + k · 1 + 5 = 0
k + 6 = 0
k = - 6
The cubic equation has a value of k equal to - 6.

please help me understand how to solve for the domain!
Given:
f(x) = x^2 + 4x + 4 and g(x) = x^2 - 2x - 8.
we are to find the domain of (f/g) (x)
before we find the domain of the function, its best we know what a domain is.
The Domain of a function is the set of all possible inputs for the function. it can also be seen as the set of input or arguement values for which the function is real and defined.
recall that we have x + 2 as our the simplest form
x - 4
so the domain we wil be looking for is x + 2
x - 4
so we have to take t denominator of the above and compare to zero
x - 4 = 0
x = 4
so this is undefined
the function domain
x < 4 or x > 4
so the domain is:
(- infinity, 4) U (4, infinity)

How do you answer these questions? How do you know whether a given value is a solution to the inequality?
We have the following inequality:
x > - 0.75
This is the same as state "x is greater than -0.75". Therefore, any value greater than -0.75 is a solution to this inequality
Considering this rule, we can answer each item:
a) The statement "-0.75 is a solution to the inequality" is FALSE, because, or rule states that x must be greater than -0.75.
b) The statement "There are many solutions to this inequality" is TRUE. Actually, there is an infinite number of solutions to this inequality (some of them can be expressed by -0.74, -0.73, -0.72...)
c) The statement "All the solutions to the inequality are negative" is FALSE, since any positive (or null) number is also greater than -0.75.
d) The statement "The inequality -0.75 < x is equivalent to the given inequality" is TRUE, since this inequality is tha same as the statement "-0.75 is less than x", which is a different form of express the original statement "x is greater than -0.75".
e) The statement "-4.5 is a solution to the inequality" is FALSE, because -4.5 is less than -0.75, which contradicts or rule.

Raina, Kevin, and Eric have a total of $66 in their wallets. Kevin has 3 times what Eric has. Raina has $9 less than Eric. How much does each have?
In order to determine the amount of money Rain, Kevin and Eric have, write the given situation as an algebraic equation.
If x is the money of Raina, y the money of Kevin and z the money of Eric, you have, based on the given problem, the following equations:
x + y + z = 66 All of them have a total of $66
y = 3z Kevin has 3 times what Eric has
x = z - 9 Raina has $9 less than Eric
Replace the expressions for x and y into the first equation and solve for z, as follow:
(z - 9) + (3z) + z = 66
z - 9 + 3z + z = 66
3z = 66 + 9
3z = 75
z = 75/3
z = 25
Next, replace the previous value of z into the expressions for x and y:
y = 3(25)
y = 75
x = 25 - 9
x = 16
Hence, the amount of money each of them has is:
Raina: $16
Kevin: $75
Eric: $75

F is the midpoint of EG. If F is at (2,-4) and G is at (8,2), where is E located?
geometry homework help line
Using midpoint of a line, the point at which E is located on the coordinates is (-4, -10)
Midpoint of a LineMidpoint refers to a point that is in the middle of the line joining two points. The two reference points are the endpoints of a line, and the midpoint is lying in between the two points. The midpoint divides the line joining these two points into two equal halves. Further, if a line is drawn to bisect the line joining these two points, the line passes through the midpoint.
The formula of midpoint is given as
(x, y) = (x₂ + x₁) / 2 , (y₂ + y₁) / 2
Taking x-coordinate
x = (x₂ + x₁) / 2
2 = (8 + x₁) / 2
x₁ = -4
Taking the y - coordinate
y = (y₂ + y₁) / 2
-4 = (2 + y₁) /2
y₁ = -10
The coordinate of E is (-4, -10)
