Answer:
40.6 inches
Step-by-step explanation:
The plant's initial height is 7 inches tall.
It grows 1.3 inches each day for 27 days. This means that after 27 days, it must have grown an extra:
1.3 * 27 = 35.1 inches
It must have grown an extra 35.1 inches after 27 days. Therefore, its new height after 27 days is:
7 + 35.1 = 42.1 inches
The plant then begins falling over 0.5 inch for the next 3 days. After 3 days, it must have fallen over by a height:
0.5 * 3 = 1.5 inches
Therefore, after 30 days, the plant's new height is:
42.1 - 1.5 = 40.6 inches
The plant's height after 30 days is 40.6 inches
If you make the denominators all the same, the fractions are 3/12 , 3/12 , and 3/12. Then by simply adding them together you get that the mural is 9/12 painted. that then simplifies to 3/4 or 75%
Hope this helps :)

Step-by-step explanation:
It literaly says it in the question.
F(x) is continuous for all x.
Pick a point and show that f(x) is either negative or positive. Pick another point and show that f(x) is negative, if positive, or positive, if negative.
At x = 30, f(30) - 1000 = 900 + 10sin(30) - 1000 ≤ 0
Now, show at another point f(x) - 1000 is positive, and hence, there would be root between 30 and such point.
Let's pick 40.
At x = 40, f(40) - 1000 = 1600 + 10sin(40) - 1000 ≥ 0
Since f(x) - 1000 is continuous, there lies a root between 30 and 40, and hence, 30 ≤ c ≤ 40
