<h2>Question:</h2>

The sum of three consecutive odd numbers is 63. Find the numbers.

<h2>Given:</h2>
  • sum of three consecutive odd numbers = 63
<h2>Let:</h2>

Three consecutive odd numbers be:

  • x
  • x+2
  • x+4
<h2>A/Q</h2>

sum of three consecutive odd numbers is 63

.°. x+(x+2)+(x+4)=63

→x+x+x=63-2-4

→3x=63-6

→3x=57

→x=57/3

→x=19

<u>We get value of x → 19</u>

Now put values in each number

First odd number= x

.°.<u>First odd number=19</u>

Second odd number =x+2

.°. Second odd number= 19+2

<u>Second odd number = 21</u>

Third odd number =x+4

.°.Third odd number=19+4

<u>Third odd number=23</u>

hope it helps!♡

Answer:

19, 21, 23

Step-by-step explanation:

Let the first odd number be n.

Then the second, consecutive odd number will be (n+2).

And the third will be (n+4).

We know that they sum to 63. Hence, we can write the following equation:

n+(n+2)+(n+4)=63

Solve for n. Combine like terms:

3n+6=63

Subtract 6 from both sides:

3n=57

Divide both sides by 3:

n=19

Hence, the first odd number is 19.

Therefore, our sequence is: 19, 21, 23.

Note: If we get an even or non-integer value for our n, then there are no three consecutive odd integers that exists that sum to 63.

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2. Determine the new coordinat
o-na [289]

Given:

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.

To find:

The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.

Solution:

If a figure is dilated by factor k with origin as center of dilation, then

(x,y)\to (kx,ky)

Where, 0<k<1 is reduction and k>1 is enlargement.

The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:

(x,y)\to (2x,2y)

Using this rule, we get

S(4,-2)\to S'(2(4),2(-2))

S(4,-2)\to S'(8,-4)

Therefore, the new coordinates of point S' are (8,-4).

If the graph of y=cos⁡θ has a change in amplitude and a vertical translation, the equation becomes y=acos⁡θ+d, where a,d∈N and 0
worty [1.4K]

Answer:

The amplitude is 3 and the downward vertical translation is 4 ⇒ 3rd answer

Step-by-step explanation:

* Lets revise some facts about the cosine function

- The Amplitude of cos(x) is the height from the center line to the

 peak (or to the trough). Or we can measure the height from

 highest to lowest points and divide that by 2.

- The Vertical Shift is how far the function is shifted vertically from

  the usual position.

* Now lets solve the question

∵ y = cos(Ф)

- There is a change in amplitude, it becomes a

- There is a vertical translation by b units

∴ y = a cos(Ф) + d

* Now lets look to the graph to find a and d

- From the graph:

∵ The highest value is -1

∵ The lowest value is -7

∴ The amplitude a = (-1 - -7)/2 = (-1 + 7)/2 = 6/2 = 3

∵ The highest value of y = cos(Ф) is 1

∵ The amplitude is 3

∴ The highest value of y = acos(Ф) = 3

∵ The highest value of y = acos(Ф) + d is -1

∴ d = 3 - (-1) = 4 ⇒ means downward vertical translation by 4

∴ y = 3 cos(Ф) - 4

* The amplitude is 3 and the downward vertical translation is 4

Find the area of a semicircle
Furkat [3]

Answer:

18pi, or 56.52

Step-by-step explanation:

To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle

However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:

(pi x radius^2)/2 = area of semi-circle

(pi x 6^2)/2 = area of semi-circle

(36 x pi)/2 = area of semi-circle

18 x pi = area of semi-circle

18 x 3.14 = area of semi-circle

56.52 = area of semi-circle
