Answer:
Euler's method is a numerical method used in calculus to approximate a particular solution of a differential equation. As a numerical method, we have to apply the same procedure many times, until get the desired result.
In first place, we need to know all the values the problem is giving:
- The step size is 0.2; h = 0.2. This step size is a periodical increase of the x-variable, which will allow us to calculate each y-value to each x.
- The problem is asking the solution y(1), which means that we have to find the y-value assigned for x = 1, through the numerical method.
- The initial condition is y(0) = 9. In other words,
.
So, if the initial x-value is 0, and the step size is 0.2, the following x-value would be:
; then
;
; and so on.
Now, we have to apply the formula to find each y-value until get the match of
, because the problem asks the solution y(1).
According to the Euler's method:

Where
, and
;
.
Replacing all values we calculate the y-value assigned to
:
.
Now,
,
. We repeat the process with the new values:

Then, we repeat the same process until get the y-value for
, which is
, round to four decimal places.
Therefore,
.
(x - 3)^2 + (y + 2))^2 = 49

Answer:
B the line goes down so its a negative gradient
and you do rise which is -1 over run which is 3
I can’t answer anything from my side so I will guide you the best I can! Measure the highlighted lines on the image. Then record the numbers into the correct areas(length,width,height). Then multiply all of the numbers above. That’s how you answer question 3. I’m sorry that I can’t do much more on my side.
