Step-by-step explanation:

A Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case you know that the triangle ABC was dilated by this scale factor:

With the origin as the center of dilation.

Since:

It is a Reduction.

You can identify that the vertices of the triangle ABC are:

So you need to multiply the coordinates of each vertex  of the triangle ABC by , in order to get the coordinates of the triangle A'B'C. Then, you get:

The value of [tex]a_{4} = 37[/tex].

Here,

The value of [tex]a_{1} = 4[/tex]

And,  [tex]a_{n} = 2 a_{n-1} -1[/tex]

We have to find value of [tex]a_{4}[/tex].

What is Sequence?

A sequence is a collection of elements that are arranged according to a specific pattern.

Now,

The value of [tex]a_{1} = 4[/tex]

And,  [tex]a_{n} = 2 a_{n-1} -1[/tex]

Then to find value of [tex]a_{4}[/tex], we can find [tex]a_{2} , a_{3}[/tex] as;

[tex]a_{2} = -2(a_{1} ) - 1\\a_{2} = -2(4) - 1\\a_{2} = -9[/tex]

And,

[tex]a_{3} = -2(a_{2} ) - 1\\a_{3} = -2(9) - 1\\a_{3} = -19[/tex]

Hence, the value of [tex]a_{4}[/tex] is;

[tex]a_{4} = -2(a_{3} ) - 1\\a_{4} = -2(-19) - 1\\a_{4} = 37[/tex]

Therefore, The value of [tex]a_{4} = 37[/tex].

Answer:

V=39.25. the height is not 6.25, 6.25 is the slope. you have to use Pythagoras theorem to find the height, then you can find the volume.

The surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².

Volume of cones the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

Volume of cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

The height of the cone is 6.5 cm and the radius is 2.5 cm. Put the values in the above formula,

[tex]V=\dfrac{1}{3}\pi r^2h\\V=\dfrac{1}{3}\pi (2.5)^2(6.5)\\V=\dfrac{1}{3}\pi (6.25)^2(6.5)\\V=\dfrac{40.625\pi }{3}\\V\approx42.5\rm\;cm^3[/tex]

The surface area of cone can be find out by the following formula,

[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]

Again put the values in this formula,

[tex]A=\pi \times2.5(2.5+\sqrt{(6.5)^2+(2.5)^2})\\A=\pi \times2.5(2.5+\sqrt{48.5})\\A=\pi \times2.5(2.5+6.96)\\A=\pi \times2.5(9.46)\\A=74.33\rm\; cm^2[/tex]

Thus, the surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².

Thanks in Advance For Brainiest

Step-by-step explanation:

First, we want to find the area of the circle at the top of the cylinder, so we want to do πr^2 so 3.14x(11.4/2)^2

This is = to 102.0186

Then we do 102.0186 times the height or 10.7 to get 1091.59902

We simplify to get 1091.6

Answer:

m∡B = 55°

AB = 5.2

AC = 7.4

Step-by-step explanation:

m∡B = 180-(90+35)

use Law of Sines to find AB and AC:

sin 90° / 9 = sin 35°/AB

AB = .57(9) = 5.2

sin 90° / 9 = sin 55°/AC

AC = .82(9) = 7.4

The solution is,

m∡B = 55°

AB = 5.2

AC = 7.4

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

from the given figure, we get,

m∡B = 180-(90+35)

        =55

use Law of Sines to find AB and AC:

sin 90° / 9

= sin 35°/AB

AB = .57(9)

     = 5.2

sin 90° / 9 = sin 55°/AC

AC = .82(9

     = 7.4.

Answer:

The circumference of the circle has a measurement of 44 inches

Step-by-step explanation:

From the question, as we can see, the given length represents the diameter of the circle

To get the circumference of the circle, we use the formula for the circumference

this is;

C = pi * d

in this case, d = 14 in

Thus, we have it that;

C = pi * 14 = 14 * 22/7 = 44 in
