Answer:

The radius of the sphere is 9 ft.

Step-by-step explanation:

Given : The volume of a sphere is 972π ft³.

To find : What is the radius of the sphere?

Solution :

The formula of volume of sphere is V=\frac{4}{3}\pi r^3

Where, Volume of the sphere is 972π ft³.

r is the radius of the sphere.

Substitute the value in the formula,

972\pi=\frac{4}{3}\pi r^3

r^3=\frac{972\pi\times 3}{4\pi}

r^3=729

r=\sqrt[3]{729}

r=9

Therefore, The radius of the sphere is 9 ft.

Trigonometry:
We know that   csc x = 1 / sin x    and π = 180°;
sin 5π/ 6 = sin 150° = 1/2
csc 2π / 3 = 1 / sin 120° = 1 / √3/2 = 2 / √3
Finally:
4 · 1/2 + 7 · ( 2 / √3 )² = 2 + 7 · 4/3 = 
= 2 + 28/3 = 2 + 9 1/3 =  11  1/3

2^x-4x=0 find the value of x in the equation
ella [17]

9514 1404 393

Answer:

  x ≈ 0.309906932381 or 4

Step-by-step explanation:

There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.

Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.
