The diameter of the circle whose circumference is 47.1cm comes out to be 15cm

Let us assume the diameter of circle whose circumference be x

The formula for circumference of the circle is 2 r

As we are already been provided with the circumference of the circle in the question as 47.1 cm

The radius of circle is half of the diameter of the circle

So, the radius of the circle is x/2

 2 r = 47.1

We will use the value of as 3.14 as provided in the question

2 3.14 x/2 = 47.1

3.14x= 47.1

X=47.1/3.14

X= 15cm

So, the diameter of the circle whose circumference is 47.1cm comes out to be 15cm

The correct question is What is the diameter of a circle whose circumference is 47.1 cm? use 3.14 for pi and enter your answer as decimal

Simplifying the given polynomial expression is; -(1/4)x³ - (7/2)x² + (214/16)x + (7/2)

We want to simplify the polynomial expression;

((1/2)x + 2)((1/2) - 2x) + ((1/4)x + (7/2))

Let us expand the first bracket to get;

((1/2)x * (1/2) + (2 * (1/2)) - ((1/2)x * 2x) - (2 * 2x))

⇒ (1/4)x + 1 - x² - 4x

⇒ 1 + (15/4)x - x²

Thus, our expression is now;

(1 + (15/4)x - x²)((1/4)x + (7/2))

This can be multiplied out to give;

(1/4)x + (15/16)x - (1/4)x³ + (7/2) + (105/8)x - (7/2)x²

= -(1/4)x³ - (7/2)x² + (107/8)x + (15/16)x + (7/2)

x - intercept; (80, 0)

y - intercept; (0, ∞)

Step-by-step explanation:

Let Week be w and Amount be A;

We see an inverse proportionality;

[tex]{ \rm{w \: \alpha \: \frac{1}{A } }} \\ \\ { \rm{w = \frac{m}{A} }}[/tex]

m is a constant of proportionality;

When w is 1, A = 68

[tex]{ \rm{ 1 = \frac{m}{68} }} \\ \\ { \rm{m = 68}}[/tex]

Therefore;

[tex]{ \tt{w = \frac{68}{A} + c }} \\ [/tex]

c is a constant;

When w is 0, A is 80

[tex]{ \rm{0 = \frac{68}{80} + c}} \\ \\ { \rm{c = - \frac{17}{20} }}[/tex]

Overall equation:

[tex]{ \rm{y = \frac{68}{x} + \frac{17}{20} }} \\ [/tex]

For x-intercept, y = 0

[tex]{ \rm{ \frac{17}{20} = \frac{68}{x} }} \\ \\ { \rm{x = 80}}[/tex]

For y-intercept, x = 0

y = ∞

The length and width of the rectangle is 23 and 11 cm.

Given, perimeter = 68 cm

A rectangle's perimeter P is determined by the equation P=2l+2w, where l is the rectangle's length and w is its width. In the formula A=lw, where l is the length and w is the width, the area A of a rectangle is determined.

let the width of the rectangle be x.

and length of the rectangle be 12 ₊ x

Formula of the perimeter = 2l ₊ 2w

68 = 2(12 ₊ x) ₊  2x

68 = 2x ₊ 24 ₊ 2x

68 ₋ 24 = 4x

44 = 4x

x = 44/4

x = 11

Hence the width of the rectangle is 11 cm and length:

12 ₊ x

= 12 ₊ 11

= 23 cm

Hence we get the length and width of the rectangle as 23 and 11 cm.

In linear equation, S = x2 + 36/x  the surface area S of the box as a function of the length x of one of the sides.

What in mathematics is a linear equation?

Let x = length of the sides of the base, and h = the height.  The volume is given as 9 m3

Volume = area of base * height

9 = x2*h

So 9/x2 = h

The surface area, S, of the box is:

S = (Area of Base) + 4*(Area of a Vertical Side)

S = x2 + 4 * (xh)

Substitute 5/x2 in place of h:

S = x2 + 4 * x * (9/x2)

S = x2 + 36/x

The model is said to have a scale of 1/12 of the original stone landmark which means that if the original famous landmark weighs 86 tons, the tons of the model can be found by the formula:

12x = 86

When solving for x which is the tons of the completed sculpture, the weight would be:

12x = 86

x = 86 / 12

4) w(x) = 3x - 1 --> replace the x with -8

6) k(n) = 3n² - 1 --> replace the n with 4

8) g(a) = -2a² + 5 --> replace the a with 9

For example, for number 8, the answer would be -157 if you plug in the value.
