Given:
Radius = 7cm
Central angle (theta) = 40 degrees

Asked:
Arc length (s)

SOLUTION:
s = 2*pi*radius*(central angle/360)
s = 2(3.14)(7cm)(40 degrees/360 degrees)
s = 4.88 cm

Therefore, the arc length of the circle is 4.88 centimeters.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

State the range of possible values for x if (3x+5)(x-1) &lt; 2x+7
lara31 [8.8K]

we are given with the inequality

(3x+5)(x-1) < 2x+7\\ \\

Open the parenthesis we get on left side we get

(3x+5)(x-1) < 2x+7 =3x^2-3x+5x-5

Which function is a quadratic function? u(x) = –x 3x2 – 8 v(x) = 2x2 8x3 9x y(x) = x2 3x5 4 z(x) = 7x2 2x3 – 3.
Komok [63]

The function u(x)=-x+3x^{2} -8 is a quadratic function due to the highest exponent being 2.

Given functions are:

u(x)=-x+3x^{2} -8

v(x)=2x^{2} +8x^3+9x

y(x)=x^{2} +3x^5+4

z(x) =7x^{2} +2x^3-3

<h3>What is a quadratic function?</h3>

A function of the form f(x)=ax^{2} +bx+c with a\neq 0 is called a quadratic function means the highest exponent of polynomial should be 2.

Let us check one by one.

u(x)=-x+3x^{2} -8

Highest exponent =2

The function is also of form f(x)=ax^{2} +bx+c so u(x) is a quadratic function.

The functions v(x), y(x), and z(x) are having highest exponents as 3,5, and 3 respectively so they are not quadratic functions.

Hence, the function u(x)=-x+3x^{2} -8 is a quadratic function due to the highest exponent being 2.
