a square figure with side 4 ft has a semicircle with radius 2ft at the top what is the perimeter of the figure ? what formula sh

andreyandreev [35.5K]

Answer:

~18.28 ft. / 12 + 2π ft. (Read explanation please!)

Step-by-step explanation:

<u>I) Find the square's perimeter:</u>

Obviously, a square's perimeter is its side length x 4. However, there would be a semicircle on top of it. So, to find it we use:

4 x 3 = 16 ft. (Since 1 of the sides is covered by the semicircle)

<u>II) Find the semicircle's perimeter:</u>

Finding the semicircle's perimeter is a bit more complicated, but no worries! We can use this formula:

<em>πr + 2r (pi x radius + radius x 2)</em>

But WAIT: We need to make sure we remove that one side of the square we mentioned earlier. So we would use:

<em>πr (pi x radius)</em>

In terms of π, the perimeter would be:

<em>2π = 2π ft.</em>

Or, if you used a standard approximation of π, let's say 3.14, it would be:

<em>2(3.14) = ~6.28 ft.</em>

<u>III) Add them up:</u>

If we wanted to state the total perimeter using 3.14 as π, we would say the formula is:

2(3.14) + 4(3) = 18.28 ft.

Or in terms of π:

2π + 4(3) = 12 + 2π ft.

Which statement is true about the factorization of 30x2 + 40xy + 51y2? The polynomial can be rewritten after factoring as 10(3x2

iragen [17]

Answer:

The greatest common factor of the terms is 1.

Step-by-step explanation:

The terms have no variables in common, and the coefficients have no factors in common. The greatest common factor of the terms is 1.

__

The discriminant is negative (40² -4(30)(51) = -4520), so any linear factors will be complex.

What are the vertical and horizontal asymptotes for the function f (x) =<img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%

yaroslaw [1]

Answer:

B. vertical asymptote: x = 1

horizontal asymptote: y = 0

Step-by-step explanation:

1) Vertical asymptotes of a function are determined by what input of x makes the denominator equal 0. So, let's set the denominator, $x^3-1$ , equal to 0 and solve for x:

$x^3-1= 0\\x^3 = 1\\\sqrt[3]{x^3} = \sqrt[3]{1} \\x = 1$

Thus, the vertical asymptote is x = 1.

2) If the degree of the polynomial in the denominator is greater than the one on the top, the horizontal asymptote is automatically y = 0. Thus, the horizontal asymptote is y = 0.
