Please help me, I can't understand
2 answers:
check out the document I have uploaded, and the things I have done in blue; that's how you should show the inequality x>5/2
I have colored the right side because x is greater than 5/2, so instead of coloring the left side because if I color the left side it means that x is less but mow you get the inequality as x greater so you should color the side which increases
the left side means that it decreases
(I wanted to help you with the drawing since you already go help with solving and finding the inequality) Have a great day and I hope this helps

The picture of how the graph looks like is shown in the picture.
Part A. The correlation coefficient, R², is the quantitative evaluation of how the data points are well-fitted to a model. The closer it is to 1, the better. But a R²=1 is very ideal and rare. This can be only true if the points coincides exactly with the given model. Since we can see in the graph that the points are exaclty passed through by the linear model, the correlation coefficient is 1.
Part B. The slope of the graph is measured between two points as Δy/Δx. So, between 1 to 4 hours, the slope is: (85-100)/(4-1) = -5. The slope represents the instantaneous rate of change of surface area with time. It is called instantaneous because the change was only between than interval, not the whole set of data. Also, the negative sign signifies that the trend is decreasing.
Part C. The data represents causation if the time was the cause of the change of the pond's surface area. However, this is not technically true because there might be other factors to be considered like environmental conditions. But, definitely, these data are in correlation because together they show an observable trend.

Answer:
Step-by-step explanation:
To work out the volume you would need to multiply all the values together.
to work out the surface area you would
