Before we do anything we must convert radians to degrees using a table. pi/3 radians equals 60 degrees, meaning the central angle of this arc is 60 degrees. This also tells us that the length of the arc is 1/6 of the whole circumference. All we have to do now is calculate the circumference which is diameter x pi.

arc = 1/6 pi x 36
arc = 6pi cm

Andrej [43]

The value of x is 4.

Step-by-step explanation:

Consider a Rectangle ABCD

AB as Top

CD as Bottom

AB = -1 + 4x

CD = 3x + 3

To Find:

x = ?

Solution:

In a Rectangle ABCD

Opposite sides of rectangle congruent,

AB = CD

Top = Bottom

A home-based sign company uses this function to model its monthly profit, where x is the price of each sign it sells.
kifflom [539]

Answer:

p(20) = 4460

Step-by-step explanation:

Given

p(x) = -10x^2 + 498x - 1500

Required

Evaluate p(x) when x = 20

To do this, we simply substitute 20 for x

p(x) = -10x^2 + 498x - 1500

p(20) = -10 * 20^2 + 498 * 20 - 1500

p(20) = -10 * 400 + 9960 - 1500

p(20) = -4000 + 9960 - 1500

p(20) = 4460
