The arc length of the circle exists 846.65922 cm.

<h3>How to estimate the central angle in degree? </h3>

A unit circle by definition contains a radius of 1 unit.

We have to estimate the length of the arc subtended by an angle of $7\pi/2$ radians.

arc length = radius $*$ angle

s = r $$ * \theta$

Where s be the arc length

r be the radius of the circle

$\theta$ be the angle measured in radians

arc length = 77cm $$*7\pi/2$

arc length = 77 $*$ 7(3.14) / 2

arc length = 846.65922 cm

Therefore, the arc length of the circle exists 846.65922 cm.

Gwar [14]

Answer:

width = let width be w

area = 140

length = 2w-6

Area of a rectangle = l*b

⇒ 2w-6*w=140

⇒ $2w^2-6=140\\2w^2 = 146\\w^2 = 146/2\\w^2 = 73\\w = \sqrt{73}$

Find the zeros of the function.

vlabodo [156]

The answer is
f(x) = 9x3 + 18 x2 - 135x can be written as f(x) = x( 9x2+ 18 x - 135)
the first zero must be = 0
let's find the another zeros by solving 9x2+ 18 x - 135=0
f(-5)=135-135=0, so the answer is
<span>
0, -5, and 3

because </span><span>f(x) = 9x3 + 18 x2 - 135x =x (x+5)(x-3)</span>
