George is solving the equation below by finding successive approximations. He started from a graph where he found the solution t
skelet666 [1.2K]

The mistake made by George is; D:George should have averaged the two differences instead of the two bounds.

<h3>How to Solve Successive Approximations?</h3>

In Mathematics, successive approximation can be defined as a classical method that is used in Calculus for solving integral equations or initial value problems.

In this question, George started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that George made a mistake instep 5 because he should have used x = 3/2 as the new upper bound.

Can someone please help me, I need step by step. Thank you

BCDE is a square of 576 square feet, so each side is √576=24 feet
BE=24
BF:FE=2:1, so BF=16, FE=8
Area of ABF is half of BE times AE (AE is the height): 1/2 of 16*12=96
the answer is 96 square feet

#6 :) :) how do you do this ?????
Romashka-Z-Leto [24]
The common difference is -5
right now, a₁₂ = 22

to get a₁, subtract 5 each time you subtract one from the subscript

so

a₁₁ = 17
a₁₀ = 12
a₉ = 7
a₈ = 2
a₇ = -3
a₆ = -8
a₅ = -13
a₄ = -18
a₃ = -23
a₂ = - 28
a₁ = -33



a₁ = -33

hope this helps
