The large sphere has a diameter of 20 feet. Which expression represents the volume, in cubic units, of the shaded part of the sphere? 4f 0 (106) + M4 ㅇ (10) - [4) ㅇ (20) + (4) ㅇ (20) - (43)
Answer:
it would be (10)- (4)
Step-by-step explanation:
The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.
What is diameter?Diameter is a straight line passing through the centre of a circle or other safe, or the length of first as millimetre centimetre inches and feet.
here, we have,
The expression that represents the volume of the shaded part of the sphere is (4/3)πr³,
where r is the radius of the sphere,
which is 10 feet (1/2 the diameter).
Therefore, the expression for the volume of the shaded part of the sphere is
(4/3)π(10)³,
or 4,188.7902 cubic feet.
Hence, The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.

An event management company purchases a new van. The value of the van, x years after the purchase, is shown in the table.
Time (years) 0 1 2 3
Value (dollars) 20,000 18,000 16,200 14,580
Which statement is true?
A.
The situation can be modeled by an exponential decay function with a percent change of -10%.
B.
The situation can be modeled by an exponential growth function with a percent change of 11%.
C.
The situation can be modeled by an exponential decay function with a percent change of -11%.
D.
The situation can be modeled by an exponential growth function with a percent change of 10%.
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

Resolver las siguientes inecuaciones cuadráticas y presentar el conjunto solución en forma de intervalo y gráficamente. 1) X2 < 10 – 3x 2) 2x2 + 3x ≥ 2
Respuesta:
1) (-5,2)
2) [tex](-\infty,-2]U(\frac{1}{2},\infty)[/tex]
Explicación paso a paso:
1)
[tex]x^{2}<10-3x[/tex]
Para comenzar este problema, debemos moverlo todo al lado izquierdo de la inecuación, por lo que obtenemos:
[tex]x^{2}+3x-10<0[/tex]
Ahora podemos factorizar el lado izquierdo para obtener:
[tex](x+5)(x-2)<0[/tex]
Ahora podemos cambiar el símbolo < por un = para encontrar los valores de x en los cuales la inecuación es igual a cero.
(x+5)(x-2)=0
Y luego despejamos x.
x+5=0
x=-5
y
x-2=0
x=2
Ahora construimos nuestros intervalos posibles.
[tex](-\infty,-5)[/tex]
(-5,2)
y
[tex](2,\infty)[/tex]
Y escogemos algunos valores de prueba. Estos nos ayudarán a determinar si cada intervalo hace que la inecuación sea verdadera o falsa.
[tex](-\infty,-5)[/tex]
Para este intervalo escojamos -6 y evaluemoslo en la inecuación.
(x+5)(x-2)<0
(-6+5)(-6-2)<0
(-1)(-8)<0
8<0
falso, así que este intervalo no es parte de nuestra respuesta.
(-5,2)
para este escojamos x=0 y probémoslo en la inecuación.
(x+5)(x-2)<0
(0+5)(0-2)<0
(5)(-2)<0
-10<0
verdadero, así que este intervalo es parte de nuestra respuesta.
[tex](2,\infty)[/tex]
Para este escojamos 3 y probémoslo en unestra inecuación.
(x+5)(x-2)<0
(3+5)(3-2)<0
(8)(1)<0
8<0
falso, así que este intervalo no es parte de nuestra respuesta.
así que nuestra respuesta es: (-5,2)
Vea imagen adjunta para representación gráfica.
2)
[tex]2x^{2}+3x\geq2[/tex]
Para resolver este problema, comenzamos moviéndolo todo al lado izquierdo de la inecuación.
[tex]2x^{2}+3x-2\geq0[/tex]
Ahora podemos factorizar el lado izquierdo de la inecuación para obtener:
[tex](2x-1)(x+2)\geq0[/tex]
Ahora podemos cambién el símbolo ≥ por un símbolop de = para obtener los valores de x que hacen que la inecuación sea igual a 0.
(2x-1)(x+2)=0
y ahora despejamos x.
2x-1=0
[tex]x=\frac{1}{2}[/tex]
y
x+2=0
x=-2
Ahora construimos nuestros intervalos posible.
[tex](-\infty,-2][/tex]
[tex][-2,\frac{1}{2}][/tex]
y
[tex][\frac{1}{2},\infty)[/tex]
Ahora escogemos los valores de prueba correspondientes.

para este, escojamos -3 y probémoslo en la inecuación.
[tex](2x-1)(x+2)\geq0[/tex]
[tex](2(-3)-1)(-3+2)\geq0[/tex]
[tex](-7)(-1)\geq0[/tex]
[tex]7\geq0[/tex]

[tex][-2,\frac{1}{2}][/tex]
para este, utilicemos 0 como valor de prueba.
[tex](2x-1)(x+2)\geq0[/tex]
[tex](2(0)-1)(0+2)\geq0[/tex]
[tex](-1)(2)\geq0[/tex]
[tex]-2\geq0[/tex]

Jordan places two boards end to end to make one shelf. The first board is 47/100 meter long, the second board is 5/10 meter long. What is the total length, in meters, of the two boards?
A. 9 7/10
B. 5 2/10
C. 97/100
D. 52/100
Please help ASAP!
Answer:
97/100 meters
Step-by-step explanation:
here's the link
=> the measure of first board = 47/100 meters
=> the measure of second board = 5/10 meters
=> total length = 47/100 + 5/10
=> length = (47+50)/100
=> length = 97/100 meters

What is the area of the following circle?
r = 4
Answer:
The area of this circle is 50.27
Step-by-step explanation:
The area of this circle is 50.3 units² or 16π
What is incircle?The incircle is defined as the largest circle that can be made in a triangle and is tangent to each side of the triangle.
The area of the circle is the product of the pie and the square of the radius.
The area of the circle = πr²
We are given that radius of the circle as r = 4.
Then we know that
Area = πr²
Substitute the values r = 4
π = 3.14
Area = 3.14(4)²
Area = 3.14 × 16
Area = 50.3
