El radio de la base de un cono circular recto mide 18.8 cm. ¿Cuál es el mayor valor que se puede tomar la altura h, para que el volumen sea máximo 416.4 centímetros cúbicos?

Answers

Answer 1

Respuesta:

21,16cm

Explicación paso a paso:

Volumen de un cono = 1 / 3πr²h

r es el radio de la base del cono

h es la altura del cono

Dados los siguientes valores

radio r = 18,8cm

Volumen = 416,4 centímetros cúbicos

Sustituir en la fórmula y obtener la altura.

Volumen de un cono = 1 / 3πrh

416,4 = 1 / 3π (18,8) h

416,4 = 1/3 * 3,14 * 18,8 h

416,4 = 19,6773h

Intercambio

19,6773h = 416,4

h = 416,4 / 19,6773

alto = 21,16 cm

Por lo tanto, el valor más grande que se puede tomar para la altura h, por lo que el volumen es un máximo de 416,4 centímetros cúbicos es 21,16 cm.

In the diagram, AP is a tangent and PBC is a secant in a circle O. If PC = 12 and BC = 9, what is AP?

Answers

Answer:

6

Step-by-step explanation:

AP^2 = PC * PB

We have PC and BC. We need PB.

PC = 12

BC = 9

PB + BC = PC

PB + 9 = 12

PB = 3

AP^2 = 12 * 3

AP^2 = 36

AP = 6

Answer: 6

Answer:

Hey!

AP will be 6cm.

Step-by-step explanation:-

to solve this, the equation  PB X PC = [tex]AP^{2}[/tex]  can be used

In the ques, its given that PC= 12cm and BC = 9.

To solve this, WE NEED TO FIND PB, SO:-

PB + BC = PC

PB + 9 = 12

PB = 3cm.

Now, we can substitute this in the equation:- PB X PC = [tex]AP^{2}[/tex]

[tex]AP^{2}[/tex] = PB x PC

[tex]AP^{2}[/tex] = 3 X 12

[tex]AP^{2}[/tex] = 36

AP = [tex]\sqrt{36}[/tex]

AP = 6cm.

Volume of Cylinders, Cones, and Spheres

I NEED HELP ASAP!!

Answers

Answer:

8) 144pi

9) 196pi

11) 18pi

12) 298.67pi

Step-by-step explanation:

Cylinders

The volume of a cylinder is [tex]V = \pi r^{2} h[/tex], where r represents the radius of the base and h represents the height.

For the first cylinder, the radius of the base is 4 and the height is 9.

[tex]V = \pi (4)^{2} (9)\\V = \pi(16)(9)\\V = 144\pi[/tex]

For the second cylinder, the diameter is 6 and the height is 2. Since the radius is half the diameter, the radius is 3.

[tex]V = \pi (3)^{2} (2)\\V = \pi(9)(2)\\V = 18\pi[/tex]

Sphere

The volume of a sphere is [tex]V = 4\pi r^{2}[/tex], where r is the radius of the sphere.

The diameter is 14, meaning the radius must be 7.

[tex]V = 4\pi (7)^{2} \\V = 4\pi (49)\\V = 196\pi[/tex]

Cone

The volume of a cone is [tex]V = \pi r^{2} (h/3)[/tex], where r is the radius and h is the height.

The radius is 8, and the height is 14.

[tex]V = \pi (8)^{2} (14/3)\\V = \pi (64) (14/3)\\V = \frac{896}{3} \pi\\V = 298.67\pi[/tex]

Hallar la ecuación de la recta que pasa por el punto P(-3,-1) y por el punto de intersección de las rectas 2x − y = 9 y 3x − 7y = 19

Answers

Answer:

y = -1

Step-by-step explanation:

The standard form of equation of a line is y = mx+b

m is the slope

b is the y intercept

Get the coordinate of the point of interception of the line 2x - y = 9 and 3x - 7y = 19

Make y the subject of the formula in both expressions

For 2x  - y = 9

- y = 9- 2x

y = 2x - 9

Similarly for 3x - 7y = 19

-7y = 19 - 3x

7y = 3x - 19

y = 3/7 x - 19/7

Equating both expressions

2x - 9 = 3/7 x - 19/7

Multiply through ny 7

14x - 63 = 3x - 19

14x - 3x = -19 + 63

11x = 44

x = 44/11

x = 4

Since y =2x - 9

y = 2(4) - 9

y = 8-9

y = -1

Hence the coordinate of intersection is at (4, -1)

Get the equation of the line passing through (-3, -1) and (4, -1)

Slope m = -1+1/4+3

m = 0/7

m = 0

Get the intercept

Substitute m = 0 and (-3, -1) into y = mx+b

-1 = 0(-3) + b

-1 = b

b = -1

Get the required equation

Recall that y = mx + b

y = 0x + (-1)

y = -1

Hence the required equation is y = -1

Answer:

y = -|x-3|+2

Step-by-step explanation:

The y-intercept is 2, because absolute value takes values from 0 to infinity, and minus absolute value (as we have here) takes values from 0 to -infinity, so wee need to shift 2 upwards.

We can notice that the 0-point of the absolute value (without intercept) is at x=3, so we need |x - ?| to equal 0 when x = 3, so ? is 3.

y = -|x-3|+2

Domain: It is the set of inputs. These are the x-values for which the function is defined.

Range: It is the set of outputs. These are the y-values for the function.

Asymptote: The function approaches to a line as x approaches to -∞ or ∞ but not intersect the line, then the line is known as asymptote.

y-intercept: It is the intersection point of the function and the y-axis.

From the given graph it is clear that the function approaches to the blue line as x approaches to -∞ but not intersect the blue line.

So, the blue line is an asymptote of the function.

QX = 5.7

Step-by-step explanation:

Here, we want to get QX

For a rectangle, the length of the parallel sides are equal

Thus,

SR will be 8 too

Since x is the midpoint of SR, we have it that RX is 4 too

The angle at each corner of the rectangle is 90 degrees each

Thus,

QRX is a right triangle

Mathematically, QX is the hypotenuse of this triangle as it is the side that faces the right angle

According to Pythagoras’ ; the square of the hypotenuse of a right triangle equals the sum of the squares of the two other sides

thus;

Qx^2 = 4^2 + 4^2

QX^2 = 32

QX = √(32)

QX = 5.7 units
