Assume the 72-gon is a regular polygon. The measure of one interior angle is how manydegrees, and the measure of one exterior angle is how many degrees?

Answer:

interior: 175°
exterior: 5°

Step-by-step explanation:

The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.

exterior angle = 360°/72 = 5°

The interior angle is the supplement of this.

interior angle = 180° -5° = 175°

The measure of one interior angle is 175°; one exterior angle is 5°.

For what side length(s) is the area of an equilateral triangle equal to 30 cm?? Only enter the number, in centimeters, rounded to two decimal places. A cm ►

Answers

Answer: The sides length are 8.32 cm

Step-by-step explanation:

An equilateral triangle has all his sides of the same lenght, so we assume that the triangle has an L lenght in his sides.

The area of a triangle is $Area = (base * height)/(2)$ where the base is L, the Area is 30 and an unknown height.

To determine the height, we cut the triangle in half and take one side. By simetry, one side has a base of $(L)/(2)$ , a hypotenuse of L and a the unknown height.

Then we apply the Pythagoras theorem, this states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, or, $hypotenuse = \sqrt{c^(2) + c^(2) }$ Where one c is $(L)/(2)$ and the other is the height.

Then we find one of the c of the equation wich will be the height.

$height = \sqrt{hypotenuse^(2)-base^(2) }$

$height = \sqrt{ L^(2) -(L)/(4) ^(2)}\nheight = \sqrt{( 3L^(2))/(4) } \n\nheight = (√(3)L )/(2)$

Finally, we use the triangle area mentioned before an find the value of L.

$30 = (L*(√(3)L )/(2) )/(2) \n\nL = \sqrt{(120)/(√(3) ) } \n\nL = 8.32 cm$

Find the arc length of the curve below on the given interval. y equals one third (x squared plus 2 )Superscript 3 divided by 2y= 1 3x2+23/2 on [00,66]

Answers

Answer

$\int_(0)^(6)√(1+12x^4+8x^2)dx$

Step-by-step explanation:

We are given that

$y=(1)/(3)(3x^2+2)^{(3)/(2)}$

Interval=[0,6]

a=0 and b=6

Differentiate w.r. t x

$(dy)/(dx)=(1)/(3)(3x^2+2)^{(1)/(2)}* 6x=2x(3x^2+2)^{(1)/(2)}$

By using the formula ; $(dx^n)/(dx)=nx^(n-1)$

We know that arc length of curve

$s=\int_(a)^(b)\sqrt{1+((dy)/(dx))^2}dx$

Substitute the values

$s=\int_(0)^(6)\sqrt{1+(2x(3x^2+2)^{(1)/(2)})^2}dx$

$s=\int_(0)^(6)√(1+4x^2(3x^2+2))dx$

$s=\int_(0)^(6)√(1+12x^4+8x^2)dx$

Length of curve,= $s=\int_(0)^(6)√(1+12x^4+8x^2)dx$

Don completes the square for the function y = x2 + 6x + 3. Which of the following functions reveals the vertex of the parabola?A. y = (x + 3)2 – 3
B. y = (x + 3)2 – 6
C. y = (x + 2)2 – 6
D. y = (x + 2)2 – 3

Answers

The function that reveals the vertex of the parabola:is y = (x + 3)² - 6.

What is the general equation of a parabola?

The general equation of a parabola is: y = a(x-h)² + k, where (h, k) indicates the vertex.

The given function is

y = x² + 6x + 3

⇒ y = (x² + 2 × x × 3 + 3²) - 6

⇒ y = (x + 3)² - 6

Therefore, the function y = (x + 3)² - 6 indicates the vertex of the parabola.
