Step-by-step explanation:
3/4=9/12 CORRECT
2/3=6/12 FALSE
Step-by-step explanation:
What is done to top of the fraction must be done to the bottom as well in order for the renaming to be true.
3*3 = 9
4*3 = 12
Therefore proven to be true
However,
2*3 = 6
but 3*3 = 9
The second fractions is renamed incorrectly and should be either 2/4=6/12 or 2/3=2/9
Hope this helps!
Answer:
The answer is A
Step-by-step explanation:
Becouse the g doesnt has a answer for it,
Answer:
The slope is 0

<span>x - intercepts (0, 0) and (120, 0)
Vertex is at (60, 35).
Part A: What do the x-intercepts and maximum value of the graph
represent?
The x-intercepts represent the points at the ground, so with that you have the width of the tunnel at ground level is 120 ft - 0 ft = 120 ft..
The vertex represents the maximum height, which is at the center of the tunnel. So, you know that the maximum height is at x = 60 ft and it is 35 ft
What are the intervals where the function is increasing and
decreasing, and what do they represent about the distance and height?
The increasing interval is (0,60), and the decreasing interval is (60,120).
That represents that the height increase from the left border (x = 0) until the center of the tunnel (x = 60 ft), reaching a height of 35 ft, and starts to decrease toward the right border until the ground level (x = 120).
Part B: What is an approximate average rate of change of the graph from x = 20 to x = 35, and what does this rate represent?
</span>
Find the y -coordinate for x = 20 and for x = 35. Supposse they are (I do not have the figure, because you did not include it) y = 15 and y = 45.
Then the average rate of change is equal to [change in height] / [change in x] = [45 - 15] / [35 - 20] = 30 / 15 = 2.
Remember that you have to use the real approximate values for the height that you can read in the figure. If the number is positive means that the height is increasing in that interval.
1/5( 1/2 + 1/3)
1/5 (3/6 + 2/6)
1/5(5/6)
5/30
1/6
