D. 1256 cm

Step-by-step explanation:

Divide the diameter by 2 to get the radius so 400/2 = 200

C = 2 π r = 2 · π · 200 = 1256.637

Answer:

x= 5

the length = 13 meters

the width = 7 meters

Step-by-step explanation:

(2x+3)(x+2)=91

2x²+7x+6=91

2x²+7x-85=0

(2x+17)(x-5) =0

x=-17/2 or x = 5

the length = 2(5)+3= 13 meters

the width = 5+2 = 7 meters

Answer:

D.

Step-by-step explanation:

when you plug in 1 to the denominator, 1 minus 1 becomes 0. a fraction with 0 as the denominator does not exist.

The limit of the function f(x)=[tex]x^{3}-1[/tex]/x-1 as x approaches 1 is 3.

Limit is the value that a function approaches as the value of variable approaches some value. They are essential to calculas and mathematical analysis and are use to define continuity , derivatives and integrals. It can change value of function at different values of x.

We have been given a function f(x)=[tex]x^{3}-1[/tex]/x-1 and we have to find the limit of function.

F(x)=[tex]x^{3} -1[/tex] /(x-1) [[tex]x^{3} -y^{3} =x^{2} +y^{2} +xy[/tex]]

[tex]\lim_{x \to \0}x^{3}-1/x-1[/tex]

[tex]\lim_{x \to \0} (x-1)(x^{2} +1+x)[/tex]/x-1

[tex]\lim_{x \to \0} x^{2} +x+1[/tex]

change limit by putting x=1-h

[tex]\lim_{h \to \0} (1-h)^{2} +1+1-h[/tex]

Put the value of h=0.

=1+1+1

=3

Hence the limit of the function [tex]x^{3}-1/x-1[/tex] is 3.

Answer:

y=7/4x–5/2

Step-by-step explanation:

You must find the slope first, let it be m

[tex]m = \frac{y2 - y1}{x2 - x1} \\ = \frac{8 - ( - 6)}{6 - ( - 2)} \\ = \frac{14}{8} \\ = \frac{7}{4} [/tex]

then insert tu the formula y=mx+c to find the c (c is the intercept of y axis) choose any point that you want. i use (6,8)

[tex]y = mx + c \\ 8 = \frac{7}{4} (6) + c \\ c = - \frac{5}{2} [/tex]

so the equation is

[tex]y = \frac{7}{4} x - \frac{5}{2} [/tex]

Answer:

where are the expressions??

Answer:

√29

Step-by-step explanation:

You would use the distance formula in this case to solve the problem:

(8-3)^2+(1-3)^2=29

Now square root 29, leaving you with √29.

Answer:

5.39

Step-by-step explanation:

√(x2 - x1)² + (y2 - y1)²

√(3 - 8)² + (1 - 3)²

√(-5)² + (-2)²

√25 + 4

√29

= 5.39

Step-by-step explanation:

The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:

y² + 15y + 56 = (y + 7)(y + a)

y² + 15y + 56 = y² + (7 + a)y + 7a

Step by step solution :

STEP  1 :

Trying to factor by splitting the middle term

1.1     Factoring  y2+14y+49  

The first term is,  y2  its coefficient is  1 .

The middle term is,  +14y  its coefficient is  14 .

The last term, "the constant", is  +49  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 49 = 49  

Step-2 : Find two factors of  49  whose sum equals the coefficient of the middle term, which is   14 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  7  and  7  

                    y2 + 7y + 7y + 49

Step-4 : Add up the first 2 terms, pulling out like factors :

                   y • (y+7)

             Add up the last 2 terms, pulling out common factors :

                   7 • (y+7)

Step-5 : Add up the four terms of step 4 :

                   (y+7)  •  (y+7)

The solution is:

  y  =  -7  

 The solution is:

 y = -14 / 2 = -7

A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number. By definition, for any number x, x% = x100.

Hi there!

I believe your answer is:  

Vertex: (0, 39)

Axis of Symmetry: x = 0  

»»————-　★　————-««  

Here’s why:

⸻⸻⸻⸻

⸻⸻⸻⸻

The 'x' value of the vertex is '0', so the axis of symmetry is [tex]x = 0[/tex].

⸻⸻⸻⸻

See the graph that I have attached.

Hope this helps you. I apologize if it’s incorrect.  

Answer:

For equation:

[tex]f(x)=x^2-16x+55[/tex]

Vertex: [tex](8,-9)[/tex]

Axis of symmetry, ([tex]x=8[/tex])

For equation,

[tex]f(x)=x^2-16+55[/tex]

Vertex:[tex](0,39)[/tex]

Axis of symmetry, ([tex]x=0[/tex])

Step-by-step explanation:

The x-coordinate of the vertex of a parabola indicates the line of symmetry of the parabola. Thus, to solve this problem, one must find the vertex of the parabola. This can be done through a process called completing the square.

Completing the square is a process that converts a quadratic equation in standard form into vertex form. The first step is to group the linear and quadratic terms. Then factor out the coefficient of the quadratic term. After doing so, add a term to make the group a perfect square trinomial, then balance the equation.

Possibility 1

If the given equation is the following,

[tex]f(x)=x^2-16x+55[/tex]

Group,

[tex]=(x^2-16x)+55[/tex]

There is no quadratic term, thus, complete the square,

[tex]=(x^2-16x+64)+55-64[/tex]

Simplify,

[tex]=(x-8)^2-9[/tex]

Vertex: [tex](8,-9)[/tex]

Axis of symmetry, ([tex]x=8[/tex])

Possibility 2

If the given equation is the following,

[tex]f(x)=x^2-16+55[/tex]

Combine like terms,

[tex]=x^2+39[/tex]

Put in vertex form,

[tex]=(x)^2+39[/tex]

Vertex:[tex](0,39)[/tex]

Axis of symmetry, ([tex]x=0[/tex])

Answer:

[tex]y = - \frac{7}{3} x + 4[/tex]

Step-by-step explanation:

I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
