Step-by-step explanation:
The formula to calculate the circumference of a circle is:
Circumference = 2πr
where "r" is the radius of the circle and "π" is the mathematical constant pi, approximately equal to 3.14159.
Given that the circumference of the circle is 20 ft, we can plug in the values into the formula and solve for "r":
20 = 2πr
Divide both sides of the equation by 2π:
r = 20 / (2π)
Simplify the expression by using the approximation of π as 3.14159:
r = 20 / (2 x 3.14159)
r = 3.1831 ft (rounded to four decimal places)
Therefore, the radius of the circle is approximately 3.1831 feet.

Answer:
-27e^(-2).
= -3.654 to 3 decimal places.
Step-by-step explanation:
d/dx((3x^2 + 3)e^-x)
Using the Product Rule:
Derivative = (3x^2 + 3) d/dx(e^-x) + e^-x d/dx(3x^2 + 3)
= -e^-x(3x^2 + 3) + e^-x(6x)
= e^-x(6x -1*(3x^2 + 3))
= e^-x(6x - 3x^2 - 3)
= 3e^-x(2x - x^2 - 1)
= -3e^-x(x^2 - 2x + 1)
= -3e^-x(x - 1)^2

Solve the system of equations using substitution. y = 4x y = 8x + 8 (−3, −12) (−2, −8) (2, 8) (3, 12)
Answer:
(- 2, - 8 )
Step-by-step explanation:
y = 4x → (1)
y = 8x + 8 → (2)
substitute y = 8x + 8 into (1)
8x + 8 = 4x ( subtract 4x from both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2

A second polygon A prime B prime C prime D prime E prime with E prime at negative 3 comma negative 3. Reflection across the x-axis Reflection across the y-axis Reflection across y = −1 Reflection across x = −3
The line of reflection is y = -1, which is the equation of the horizontal line passing through the midpoint of the line segment joining E and E'.
A line section is what?Two different points on a line define the boundaries of a line segment in geometry. Or, a line segment is a section of the line that links two points, as another alternative. In contrast to a line, which has no endpoints and can go on forever, a line segment has two distinct endpoints that are set or identifiable.
According to the given information:From the given image, we can see that the original polygon ABCDE has point E at (-3, 1), and the reflected polygon A'B'C'D'E' has point E' at (-3, -3). This means that the reflection must have occurred across the horizontal line passing through the point (-3, -1), which is the midpoint of the line segment joining E and E'.

The radius of the circle is r = 3.75
What is the radius of a circle?The radius of a circle is the distance from its center to its circumference.
To find the radius of the circle, we see that there is a right-angle triangle there. So, using Pythagoras' theorem, we have that
AC² = AB² + BC²
(6 + r)² = 9² + r²
Expanding the brackets, we have that
36 + 12r + r² = 81 + r²
Cancelling out r², we have that
36 + 12r = 81
Subtracting 36 from both sides, we have that
12r = 81 - 36
12r = 45
r = 45/12
r = 15/4
r = 3.75
So, the radius is r = 3.75

What is surface area
Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².
What is the explanation for the above response?
Surface area is the measure of the total area that the surface of a three-dimensional object occupies.
To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:
Surface area = 2(lw + lh + wh)
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
So, if we have a rectangular prism with the following dimensions:
Length (l) = 3.5 inches
Width (w) = 4 inches
Height (h) = 6 inches
The surface area can be calculated as follows:
Surface area = 2(lw + lh + wh)
= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)
= 2(14 + 21 + 24)
= 2(59)
= 118In²
Therefore, the surface area of this rectangular prism is 118 In².

You may choose more than one correct answer. m 4 + m 5 + m 6 = 180. 1 and 4 are alternate interior angles. m 5 = m 3 + m 2. m 5 + m 1 = 180.
m4 + m5 + m6 = 2m4 + m5 = 180, which proves that the interior angles of a triangle have a sum of 180 degrees.
What is interior angles of a triangle?Interior angles of a triangle are the angles formed inside a triangle at each of its vertices. The sum of these angles is always 180 degrees in a Euclidean plane.
This statement can be used because lines l and m are parallel, which means that m4 and m6 are corresponding angles and are congruent. This means that m4 = m6. Also, m5 and m4 are alternate interior angles, which means that they are congruent as well.
we can substitute m6 with m4 in the first equation to get:
m4 + m5 + m4 = 180
2m4 + m5 = 180
Therefore, the equation simplifies to:
2(180 - m5) + m5 = 180
360 - 2m5 + m5 = 180
m5 = 180 - 360 + 2m5
m5 = 2m5 - 180

Ingrum Corporation produces and sells two products. In the most recent month, Product R38T had sales of $33,000 and variable expenses of $8,840. Product X08S had sales of $54,000 and variable expenses of $32,050. The fixed expenses of the entire company were $36,130. The break-even point for the entire company is closest to:
Answer:
Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.
Step-by-step explanation:
To calculate the break-even point, we need to find the total contribution margin, which is the difference between the total sales revenue and total variable expenses.
For Product R38T, the contribution margin is $33,000 - $8,840 = $24,160.
For Product X08S, the contribution margin is $54,000 - $32,050 = $21,950.
The total contribution margin for both products is $24,160 + $21,950 = $46,110.
To calculate the break-even point, we divide the total fixed expenses by the total contribution margin:
Break-even point = Total fixed expenses / Total contribution margin
= $36,130 / $46,110
= 0.784
Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.
You deposit $6000 in an account earning 6% interest compounded quarterly. How much will you have in the account in 15 years? Round your answer to the nearest cent.
Step-by-step explanation:
The formula to calculate the future value of a present value deposit with compounding interest is:
FV = PV × (1 + r/n)^(n*t)
Where:
PV = Present Value (the initial deposit)
r = Annual interest rate (as a decimal)
n = Number of compounding periods per year
t = Number of years
Using this formula, we can calculate the future value of the $6000 deposit after 15 years:
PV = $6000
r = 6% = 0.06
n = 4 (compounded quarterly, i.e. 4 times per year)
t = 15 years
FV = $6000 × (1 + 0.06/4)^(4*15)
FV = $6000 × 1.458^60
FV = $6000 × 6.2565
FV = $37,539.00
Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.

2. The value of x is 36
What is a polygon?A polygon can be defined as a flat or plane. The sum of a regular polygon is expressed as (n-2)180. The sum of exterior angle of a polygon is 360.
Therefore the sum of the interior is 5 times the exterior.
(n-2)180 = 5×360
180n - 360 = 1800
180n = 1800-360
180n = 1440
divide both sides by 180
n = 1440/180
n = 8

144 is 90% what is the other 10 percent
Answer:
the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.
Step-by-step explanation:
To find the missing 10%, you can use the fact that 100% is equal to the whole amount, and set up a proportion:
90/100 = 144/x
Simplifying this proportion, you can cross-multiply:
90x = 100 * 144
Then, you can solve for x:
x = (100 * 144) / 90
x = 160
Therefore, the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

The quadrilateral is most specifically a parallelogram because the opposite sides are parallel to each other
What is a parallelogram?
A parallelogram is a geometric shape with four sides, where opposite sides are parallel and congruent (having the same length), and opposite angles are also congruent (having the same measure).
In other words, a parallelogram is a quadrilateral (a polygon with four sides) where both pairs of opposite sides are parallel.
The opposite sides of a parallelogram are equal in length, and its diagonals bisect each other. The area of a parallelogram is equal to the product of its base (one of its sides) and its height (the perpendicular distance between the base and the opposite side).
