Jacob is solving the equation below using successive approximations.2^x-4=3^-x-2 He started from a graph where he found the solution to be between 1 and 2. Using the lower and upper bounds from the graph, Jacob did the following work for the first iteration. Step 1 Rewrite the equation so that it equals zero on one side. Step 2 Evaluate the rewritten equation at the lower and upper bounds. To find the solution that lies between 1 and 2, set these values as the lower and upper bounds while finding the solution. Step 3 Take the average of the lower and upper bounds. Step 4 Evaluate the rewritten equation at x = . Step 5 Since this value is positive, replace the previous lower bound so that the bounds are now x = and x = 2. Where did Jacob make a mistake, and what was the error?
Answers
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.
How to Solve Successive Approximations?
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.

following statements true about the sample?
It is not a valid sample because it is only a short study,
It is a valid sample because money is offered to participants.
It is a valid sample because the first 10 people were selected to participate.
It is not a valid sample because it is not a random sample of the population

Answer:
The correct answer is the last on that’s states: it is not a valid sample because it is not a random sample of the population.
Step-by-step explanation:
When a researcher wants to know about the same thing, he/she has to take a sample from the population.
Example, consider a researcher wants to know how many hours the students study at home in a week, so the researcher has to take the sample from the student population.
Here, he/she gives the advertisement and offers $10 for 10 people. Therefore for anyone can come they might not required for a particular study.
Therefore, the answer is the last one.

Answer: Hello there!
The pairs in the table are: 3 carrots to 9 cucumbers, (dividing both sides by 3, we get 1 carrot to 3 cucumbers) wich has a ratio of 1:3.
after we got 4 carrots to 12 cucumbers, we could divide both sides by 4, and we also get a ratio of 1:3
And we can see this for all the pairs in the table, you always need to use cucumbers equal to three times the amount of carrots tat you used.
So if you use one carrot you need to use 3 cucumbers; wich ads to a total of 4 vegetables.
This is the less amount of vegetables that you can use because you can't use less than one carrot. (because you need to use whole vegetables)
Then the correct option is C.
Answer:
4
Step-by-step explanation:
The ratio of carrots to cucumber is 1:3.
The sum of their fewest amount is 4

The area would be 144cm^2.
In order to find the area, we need to know the length of the rectangle. We can find that using the perimeter formula.
2l + 2w = P
2l + 2(36) = 80
2l + 72 = 80
2l = 8
l = 4
So now that we know the length is 4, we can find the area using that formula.
A = lw
A = (4)(36)
A = 144
