Answer:
B, C, D, and F
Step-by-step explanation:
The graph is an exponential curve rising upwards. By looking at the graph we can tell that the graph is only increasing, it touches the y-axis at 30 and it lies in the 1st quadrant.
So, option A is wrong, as the graph is increasing.
Option B is correct. The point where graph crosses/touches the y-axis is the y-intercept. So the y-intercept is 30.
Option C is correct. As the graph lies in 1st quadrant and is positive over the entire range of values.
Option D is also correct as the graph is increasing over entire range of values.
Option E is incorrect as y-intercept is 30.
Option F is correct. Since the graph is increasing, this means with every passing year the number of dolphins is increasing.
Therefore, the correct options are: B, C, D, and F
You can solve it like this
2=milk (a); 1=milk (b)
9=tea (a); x= tea (b)
2:9=1:x (then multiply means and the extremes)
(means are 9 and 1; extremes are 2 and x)
9=2x
9/2= x
4.5 or 4 1/2=x
Therefore, using 1 litre of milk, we can have 4 1/2 tea.
