This is a trapezoid and the trapezoid formula is b1 plus b2/ 2 times height.

17 plus 5 is 22. Divided by 2 is 11.

Now, we have to multiply 11 by the height : 5.

11 times 5 is 55 and that is your area. 55 units squared.

What is the average rate of change of the amount of the element over the 10-minute experiment? *

Dima020 [189]

Answer:

$-2.7 g/min$

Step-by-step explanation:

Given: a graph

To find: the average rate of change of the amount of the element over the 10-minute experiment

Solution:

A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.

From the graph,

change in x (time) = $10-0=10$ minutes
