X+ 1/x= 5
⇒ (x+ 1/x)^2= 5^2
⇒ (x+ 1/x)^2= 25
⇒ x^2+ 2(x)(1/x)+ 1/x^2= 25
⇒ (x^2+ 1/x^2)+ 2*1= 25
⇒ x^2+ 1/x^2= 25 -2
⇒ x^2+ 1/x^2= 23
The final answer is 23~
Any number race to the power zero is always 1 therefore the simplified form of p^0 is 1
I hope this helps you
x^2-6x+9=0
(x-3)^2=0
x=3
A. The volume of the spaceship is calculated through the equation,
V = 4πr³/3
Dividing the given diameter by 2 to get the radius will give us 13.4 ft. Substituting the known values to the equation,
V = 4π(13.4 ft)³/3 = 10078.64 ft³
b. If we let x be the number of people allowable in the spaceship, the equation that would best represent the scenario is,
1000x + 4073.5 = 10078.64
The value of x from the equation is 6.
