A circular fountain has a drain in the center. The distance from the drain to the edge of the fountain is 3 feet. What is the circumference of the fountain? Round your answer to the nearest tenth of a foot.

Answers

Answer:

18.8 feet

Step-by-step explanation:

Since the drain is in the center, the distance between the drain and the edge is the radius of the circular fountain.

Use the circumference formula: C = 2[tex]\pi[/tex]r, and plug in 3 as r (the radius).

C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex](3)

Solve for C:

C = 6[tex]\pi[/tex]

C = 18.8

So, the circumference of the fountain is approximately 18.8 feet

How many solutions does this equation have?

–2 + 2s = –3s + 8

Answers

Answer:

Step-by-step explanation:

-2 + 2s = - 3s + 8

-2 - 8 = - 3s - 2s

-10 = - 5s

-10/-5 = s

2 = s

Answer:

2

Step-by-step explanation:

-2+2s=-3s+8

-2+2s-(-3s)=8

-2+2s+3s=8

-2+5s=8

5s=8-(-2)

5s=8+2

5s=10

s=10/5

s=2

f(x) = 2x2 + 12x + 1
Determine the vertex !

Answers

Answer:

(-3, -17)

Step-by-step explanation:

The best way to find the vertex is to rewrite the given quadratic in vertex form:  y - k = a(x - h)^2.

The given quadratic is f(x) = 2x2 + 12x + 1.  We will focus on the first two terms and "complete the square."  f(x) = 2x2 + 12x + 1 can be rewritten as

f(x) = 2(x^2 + 6x) + 1, which, after completing the square, is

f(x) = 2(x^2 + 6x + 9 - 9) + 1, or

f(x) = 2( (x + 3)^2  - 9 ) + 1, or

f(x) = 2(x + 3)^2 - 17

Comparing this to

f(x) = a(x - h)^2 + k, we see that the vertex is located at (h, k):  (-3, -17)

A hexagon is inscribed in a circle As see in the picture.Find the length of an arc between consecutive vertices. Round to the nearest hundred

Need help homework

Answers

Answer:

The length of the arc between consecutive vertices is:

[tex]S=8.38\: in[/tex]

Step-by-step explanation:

The angle between consecutive vertices is 60°, it is because it forms an equilateral triangle.

Now, the length arc is defined as:

[tex]S=R\theta[/tex]

Where:

R is the radius (R = 8 in)θ is the angle of the arc

We see the angle is in grades, but we need to convert it to radians.

[tex]\theta=\frac{60^{\circ}}{360^{\circ}}(2\pi)[/tex]

[tex]\theta=1.05\: rad[/tex]

Finally, the length of the arc between consecutive vertices will be:

[tex]S=8*1.05[/tex]

[tex]S=8.38\: in[/tex]
