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:
40 mph
Step-by-step explanation:
To find the maximum speed at which the car can travel, as the distance it requires to stop is 168 feet, we just need to use the value of d = 168 in the equation, and then find the value of s:
168 = 0.05s^2 + 2.2s
0.05s^2 + 2.2s - 168 = 0
Using Bhaskara's formula: we have:
Delta = 2.2^2 + 4*0.05*168 = 38.44
sqrt(Delta) = 6.2
s1 = (-2.2 + 6.2)/0.1 = 40 mph
s2 = (-2.2 - 6.2)/0.1 = -84 mph (a negative value does not make sense as 's' is the speed of the car)
So the maximum speed of the car is 40 mph
Answer: this is rounded out, and an estimate but...
Step-by-step explanation:
It appears to be 14.03% I could be wrong, but this was calculated so maybe not.
Salma showed me how to do it.
Here are two ways:
8 times (5·3 - 2) = 8 times (15 - 2) = 8 times 13 = 104 .
8 times (5·2 + 3) = 8 times (10 + 3) = 8 times 13 = 104.
Thank you, Salma.
