Mathematics
1 answer:
oksano4ka [1.4K]2 years ago
5 0

Answer:

Step-by-step explanation:

1. Move circle with center X, 2 units to the right and 8 units down to produce circle with radius 6 and center at the origin

2. Dilate this circle with a factor of 1/2 (or compress this circle with a factor of 2) to produce a circle with radius 3

3. Now move this circle 4 units to the right and 2 units up to produce circle Y.

 

CircleX can be transformed into circle Y by translations and a dilation, therefore the two circles are similar

Find the domain and range for the following functions:
Andreyy89

Answer with Step-by-step explanation:

Since we have given that

a. f: ℝ → ℝ given by f(x) = x + 2

Domain would be all real numbers i.e. (-∞, ∞)

Range would be all real numbers i.e. (-∞, ∞)

b. g: ℝ → ℝ given by g(x) = √x − 1

Domain would be all positive numbers i.e. [0,∞)

Range would be [-1,∞)

c. f(g(x))

f(g(x))=f(\sqrt{x}+1)=\sqrt{x}+1+2=\sqrt{x}+3

Domain would be  [0,∞)

Range would be [3,∞)

d. g(f(x))

g(x+2)=\sqrt{x+2}-1

Domain would be [-2,∞)

Range would be (0,∞)

The volume of a cone-shaped dessert is 10 CUBIC CENTIMETRES.
allochka39001 [22]

Answer:

3. 2.4 c.m

The height of the cone 'h' = 2.4 c.m

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given radius of the cone = 2 cm</em>

Given data

The volume of a cone-shaped dessert is 10 cubic centimetres

<em>The Volume of the Cone </em>

<em>                           </em>V = \frac{1}{3} \pi r^{2}h<em></em>

                        10 = \frac{1}{3} X 3.14 X (2)^{2} X h

  cross multiplication , we get

                  h = \frac{ 3 X 10}{3.14 X 4}

                 h =  2.388 ≅ 2.4 c.m

<em>The height of the cone 'h' = 2.4 c.m</em>
