One that can’t be solved so D
By definition of #,
2 # 3 = 2•2 - 3 = 4 - 3 = 1
(2 # 3) # 4 = 1 # 4 = 2•1 - 4 = 2 - 4 = -2
1 # ((2 # 3) # 4) = 1 # (-2) = 2•1 - (-2) = 2 + 2 = 4
Answer: no solution
Step-by-step explanation:
The main formula is integr U^p du = (1/1+p)U^p+1
let be U=<span>(25 - 16x^2)^-1/2,
</span>1/sqrt(25 - 16x^2) = (25 - 16x^2)^-1/2
du= -1/2)(-32x)(25 - 16x^2)^-1/2dx
integ du/-1/2)(-32x)= integ(25 - 16x^2)^-1/2dx
nteg du/16x)=1/16xu+c=integ(25 - 16x^2)^-1/2dx
finally
integ 1 / sqrt(25 - 16x^2) dx = 1/16xu+c= (1/16x)(<span>(25 - 16x^2)^-1/2) +c
</span>
45% divided by 6 people will equal percentage per person (7.5% each). So, 100% divided by 7.5% will equal how many people (answer is 13.3333333333, but you can't have one third of a person, so round to 13). Answer = 13 people
