Step-by-step explanation:
3. The tree increased in height each month until the time period between month 9 and month 11.
Step-by-step explanation:
We have been given a table that shows the height of the tree that Margo planted over an 11-month period.
Let us see which of the given statement can be supported by the information in the table.
1. The tree increased in height each month during the entire 11-month period.
We can see from our table of data that Margo's tree increased till 9 months and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, first statement is not true.
2. The tree decreased in height each month during the entire 11-month period.
We can see from our table that height of Margo's tree increased till 9 months from 1.4 feet to 3 feet and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, second statement is not true.
3. The tree increased in height each month until the time period between month 9 and month 11.
We can see that height of tree increased for 9 months (1.4 ft to 3 ft) and between 9 to 11 months height decreased (3 ft to 1.8 ft), therefore, our 3rd statement is true and the information given in the table is supporting this statement.
4. The tree decreased in height each month until the time period between month 9 and month 11.
We have seen that the tree increased in height each month until the time period between month 9 and month 11, therefore, our 4th statement is not true.
i hope this helps
Answer:
![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
You can find arc length by finding the total circumference length, then multiply it by the arc angle divided by 360. The circumference is ![6*\frac{20}{360}=\frac{1}{3}](https://tex.z-dn.net/?f=6%2A%5Cfrac%7B20%7D%7B360%7D%3D%5Cfrac%7B1%7D%7B3%7D)
<span> 3(bx - 2ab) = b(x - 7a) + 3ab
<=> </span><span>3bx - 6ab = bx - 7ab + 3ab
<=> 3bx - bx = 6ab - 7ab + 3ab
<=> 2bx = 2ab
<=> x = a</span>
The given equation is a quadratic equation and we can find the solutions of the quadratic equation using the quadratic formula.
The Quadratic formula is:
![x= \frac{-b+- \sqrt{ b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B-b%2B-%20%5Csqrt%7B%20b%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D%20)
Here,
b = coefficient of x term = 9
a = coefficient of squared term = 2
c = constant term = -5
Using the values of, we get:
![x=\frac{-9+-\sqrt{81-4(2)(-5)}}{2(2)}\\\\x=\frac{-9+-11}{4}\\\\x= \frac{-9-11}{4}=-5, x= \frac{-9+11}{4}= \frac{1}{2}=0.5](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-9%2B-%5Csqrt%7B81-4%282%29%28-5%29%7D%7D%7B2%282%29%7D%5C%5C%5C%5Cx%3D%5Cfrac%7B-9%2B-11%7D%7B4%7D%5C%5C%5C%5Cx%3D%20%5Cfrac%7B-9-11%7D%7B4%7D%3D-5%2C%20x%3D%20%5Cfrac%7B-9%2B11%7D%7B4%7D%3D%20%5Cfrac%7B1%7D%7B2%7D%3D0.5)
Thus the values of x satisfying the given equation are x = -5, x = 0.5
