The mistake made by Jacob is; D: Jacob made a mistake at step 5. He should have used x=32 as the new upper bound.
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, Jacob started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that Jacob made a mistake instep 5 because he should have used x = 3/2 as the new upper bound.

For plato users
D. Jacob made a mistake at step 5. He should have used x = 3/2 as the new upper bound.
Step-by-step explanation:
The pairs of numbers that multiply to 90 are (1, 90), (2, 45), (3, 30), (5, 18), (6, 15), and (9, 10).
To find two numbers that multiply to equal 90, we can look for pairs of factors of 90.
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
To determine the pairs of factors that multiply to 90, we can list the pairs:
1 × 90 = 90
2× 45 = 90
3 × 30 = 90
5 × 18 = 90
6 × 15 = 90
9 × 10 = 90
Therefore, the pairs of numbers that multiply to 90 are: (1, 90), (2, 45), (3, 30), (5, 18), (6, 15), and (9, 10).

An automated car wash can wash 120 carsin 20 hours.
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an automated car wash can wash 30 cars in 5 hours.
Now, an automated car wash can wash 30 cars in 5 hours.
Then, 1 car can be washed in (5/30) hours.
So, 120 cars will take (5/30 x 120) hours
(5/30 x 120)
5 x 4
20 hours
Therefore, an automated car wash can wash 120 carsin 20 hours.
