The number of balloons needed to fill the classroom are  46240 balloons (approx)

Concept: Fermi process is the technique that helps to formulate an answer to a problem based on a series of logical assumptions.

No. of balloons = Volume of rectangular prism/ Volume of each sphere (balloon)

Given: The classroom is a rectangular prism with a length of 38 ft, a width of 52 ft, and a height of 12 ft, and the balloons are spheres with a radius of 0.35 ft.

No. of balloons = Volume of rectangular prism/ Volume of each sphere (balloon)

No. of Balloons = 38*52*12/3.14*0.35*0.35*(4/3)

No. of Balloons = 23712/0.5128 = 46240 balloons (approx)

nadya68 [22]

Answer:

f'(x)=2(e^4^x)+(x^2+1)(4e^4^x)

Step-by-step explanation:

The derivative of the function:

(x^2+1)e^4^x

The rule for the product of two functions:

f'(x)=g'(x)h(x)+g(x)h'(x)

Therefore

g(x)=x^2+1

g'(x)=2

f(x)=e^4^x

f'(x)=4e^4^x

f'(x)=2(e^4^x)+(x^2+1)(4e^4^x)
