Answer:

36(x + 1)^2 = 0 or 36x^2 + 72x + 36

Step-by-step explanation:

s^2 = area of a square

(6x + 6) (6x + 6)

6x*6x = 36x^2

6x*6 = 36x

6*6x = 36x

6*6 = 36

36x^2 + 36x + 36x + 36

36x^2 + 72x + 36

36(x + 1)^2 = 0

The value of x is given from proportion and x = 9

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the first polygon and second polygon be similar

So , the ratio of their corresponding sides will also be similar

Substituting the values in the equation , we get

( x -1 ) / 6 = 16 / 12   be equation (1)

On simplifying the equation , we get

Multiply by 6 on both sides of the equation , we get

( x - 1 ) = ( 16 x 6 ) / 12

( x - 1 ) = 16 / 2

On simplifying the equation , we get

x - 1 = 8

Adding 1 on both sides of the equation , we get

x = 9

And ,

( y + 1 ) / 21 = 32 / 24   be equation (2)

On simplifying the equation , we get

Multiply by 21 on both sides of the equation , we get

( y + 1 ) = ( 4 x 21 ) / 3

y + 1 = 4 x 7

y + 1 = 28

Subtracting 1 on both sides of the equation , we get

y = 27

Hence , the value of x is 9

Question 1

The distance between the chords is sum of the distances between the center and the midpoint of the chords

The segments between the center to the midpoints of the chords for right triangles with one side being the radius.

The distance is:

------------------------------------------

Question 2

Midpoint of the side, the center and the vertex form a right triangle with 30° angle at the vertex.

Let the radius be r, the distance from the center to the side be h

Then we have:

As per property of 30°-60°=90° triangle, the side opposite to 30° is half of the hypotenuse. In this case, h = r/2 or r = 2h

Substitute r into equation above and solve for h:

Answer:

  s(t) = 2^(t-1)

Step-by-step explanation:

The amount in the account is the sum of the series ...

  1 + 1 +2 +4 +8 +16 +...

We note that terms after the first are a geometric sequence with a first term 1 and a common ratio 2. The sum of such a sequence is ...

  Sn = a1×(r^n -1)/(r -1) . . . . where n is the number of terms being summed

For our values, this simplifies to ...

  Sn = 1×(2^n -1)/(2 -1) = 2^n -1

We notice here that the account balance is 1 more than this sum, and that n = t-1, so the balance a(t) is ...

  s(t) = 1 +(2^(t -1) -1)

  s(t) = 2^(t -1) . . . . . . the function showing how much Jerry has

Answer: y= 0.5x + 5.5

Step-by-step explanation: Y = mx + C

SLOPE INTERCEPT FORM:

First we need to find the slope of the two points. Which is y2-y1 / x2-x1.

8 is Y2 and 2 is Y1. 5 is Y2 and -7 is Y1. Plug those numbers into a calculator and solve. The slope (m) is 1/2 or 0.5

Then we have to find C as the slope intercept form is Y = mx + C. To find C we replace x and y with one of the points, and solve as an algebric equation. C will be 5.5

Given:

The function is

[tex]f(x)=2x^3+kx-9[/tex]

The remainder when f(x) is divided by x−2 is 23.

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).

It is given that, the remainder when f(x) is divided by x−2 is 23. By using remainder theorem, we get

[tex]f(2)=23[/tex]       ...(i)

Put x=2, to find the value of f(2).

[tex]f(2)=2(2)^3+k(2)-9[/tex]

[tex]f(2)=2(8)+2k-9[/tex]

[tex]f(2)=16+2k-9[/tex]

[tex]f(2)=2k+7[/tex]          ...(ii)

Using (i) and (ii), we get

[tex]2k+7=23[/tex]

[tex]2k=23-7[/tex]

[tex]k=\dfrac{16}{2}[/tex]

[tex]k=8[/tex]

Therefore, the value of k is 8.
