Hope my answer helps you! :D
Answer: a = 64
Step-by-step explanation: the equation for area is a=lw. a = 16(4) which is equal to 64.
To find the minimum value of n that guarantees an error of no more than 1/30000 in approximating integral 1/x dx from 3 to 4 by the trapezoidal rule with n so the answer to your question is N=71 and i hope you understand my answer.
F(x) = -2 (x-9)2 + 14
= -4(x-9) + 14
= -2 [ 2(x-9) -7 ]
= -2 (2x -18 -7)
= -2 (2x -25)
