If a windmill with radius 26 feet makes 12 full revolutions every 1 minute, what is its linear speed?
The linear speed of the windmill is 1,960.35 feet per minute.
Given data:
To calculate the linear speed of the windmill, determine the distance traveled by a point on the circumference of the windmill in 1 minute.
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Given that the radius of the windmill is 26 feet, the circumference is:
Circumference = 2 * π * 26
Now, the windmill makes 12 full revolutions every 1 minute. Since one revolution is equivalent to one circumference, the total distance traveled in 1 minute is:
Distance = 12 * Circumference
Substituting the value of the circumference:
Distance = 12 * (2 * π * 26)
Simplifying this expression:
Distance = 24 * π * 26
Therefore, the linear speed of the windmill is equal to the distance traveled divided by the time taken, which is 1 minute:
Linear speed = Distance / Time
Linear speed = 24 * π * 26 / 1
Calculating this value, the linear speed of the windmill:
Linear speed ≈ 1,960.35 feet per minute
Hence, the linear speed is 1,960.35 feet per minute.

The sum of 2 times a number and twice its reciprocal is 20/3. Find the numbers.
Please show work because I am so lost.
Answer:
Let x represent the number from the sentence.
Step-by-step explanation:
2(x) + 2(1/x) = 20/3
2x + 2/x = 20/3
multiply both sides of the equation by 3x
6x + 6 = 20x
6x - 20x + 6 = 0
6x - 18x - 2x + 6 = 0
6x(x-3 -2(x-3) = 0
(6x-2 = 0 or x-3 = 0
6x = 2 or x = 3
x = 2/6
x = 1/3
Since x represented the number
Therefore x = 1/3 or 3

Shown here is a mathematical step taken when solving an equation. Identify the mathematical reason or property used to simplify from the first step to the second step. 8D=56. D=7
Answer:
D. Division Property of Equality
Step-by-step explanation:
Given that [tex] 8D = 56 [/tex], to find the value of D, the property of equality that needs to be applied here would be the one that would make both sides equal by performing the same operation on both sides of the equation.
Thus:
Applying the the Division Property of Equality, we would divide both sides by 8.
[tex] \frac{8D}{8} = \frac{56}{8} [/tex]
[tex] D = 7 [/tex]
This will leave you with D standing alone. Of which value is 7.

Encuentra la forma de la ecuacion de la recta que pasa por el punto P(-1,5) y que es perpendicular a la recta 2x + 3y - 8= 0
Responder:
2y-3x = 12
Explicación paso a paso:
La forma estándar de ecuación de una línea se expresa como;
y = mx + c
m es la pendiente
c es la intersección
Primero necesitamos la pendiente de la ecuación conocida;
Dada la ecuación 2x + 3y - 8 = 0
Vuelva a escribir en forma estándar;
2x + 3y = 8
3y = -2x + 8
y = -2x / 3 + 8/3
Por lo tanto, la pendiente de la línea dada es -2/3
Dado que la línea desconocida es perpendicular a la línea dada, el producto de sus pendientes será -1;
mM = -1
M = -1 (-2/3)
M = 3/2
La pendiente de la línea desconocida es 3/2
Obtener la intersección:
Sustituya m = 3/2 y el punto (-1, 5) en la expresión y = mx + cy obtenga c como se muestra;
5 = 3/2 (-1) + c
5 = -3/2 + c
c = 5 + 3/2
c = (10 + 3) / 2
c = 13/2
Obtenga la ecuación requerida;
Dado que y = mx + c
y = 3x / 2 + 13/2
multiplicar por 2;
2y = 3x + 12
2y-3x = 12
De ahí que la forma de la ecuación de la recta que pasa por el punto P (-1,5) y que es perpendicular a la recta 2x + 3y - 8 = 0 es 2y-3x = 12
