The human population of Earth was approximately 6 billion in 1998. If the rate ofpopulation growth from then on was 2.3% per year, what would be the best
approximation for the human population (in billions) of Earth in 2020?

Answers

Answer:

9.89 billion

Step-by-step explanation:

At that rate of growth, the population is multiplied by 1.023 each year. After 22 years, the population would be ...

6·1.023^22 ≈ 9.89 . . . billion

Answer:

Let the equation for the population (P) growth be given by

P = P0ert, where P0 is the initial population in billioins at time t,

t is the number of years since 1987,

r is the rate of growth of population/year

In this case P0 = 5 billion and r = 0.02. Putting these values into the equaation:

P = 5e0.02t

Year 1995 is 8 years after 1987, then the population would be

P = 5e0.02*8 = 5e0.16 ≈ 5.87 billion people

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.

Hi there!

Great question! :D

To figure out our unknown value, we can replace our unknown value, or blank space, with x.

So our equation would look something like $4x = 30$

We have a variable next to a number to show we are multiplying. But since we're figuring out an unknown, we'll do the opposite, which is division.

$4x = 30$

We'll divide both sides by our 4.

$(4x)/(4) = (30)/(4)$

We can eliminate the variable right away on our left side of our equation. This makes it look like there's not a lot of steps through solving.

$(30)/(4) = 7.5$

Final answer:

$x = 7.5$

When in doubt of your answer, we can multiply 4 by 7.5 and see what we get. We should get 30.

$4 * 7.5 = 30 :)$

We were right!

Hope this helps! :D

4x=30
4x/4=30/4
x=7.5

Hope this helps!!

The line passing through (11,y) and (2,0)is parallel to the line joining (7,5) and (-2,2). Find y.

Answers

Answer: y = 3

Step-by-step explanation:

Two lines are said to be parallel if they have the same slope. All we need to do is to find the slope of each line . The formula for finding slope is given as :

m = $(y_(2)-y_(1))/(x_(2)-x_(1))$
