9x^2+24x+16
Step-by-step explanation:
Answer:
y = 6 + 4x
After 4 years, the tree would be 22 ft tall.
Step-by-step explanation:
Hi there!
Let x = the number of years that pass
Let y = the height of the tree (ft)
We're given that the 6-foot tree grows at a rate of 4 ft per year. This means that the height of the tree will be equal to 6 ft, the original height, plus another 4 ft every year that passes.
Height of tree = 6 feet + 4 feet × number of years that pass
y = 6 + 4x
To solve for how tall the tree would be 4 years after Dina plants it, replace x with 4, since 4 years have passed:
y = 6 + 4(4)
y = 6 + 16
y = 22
Therefore, the tree would be 22 ft tall.
I hope this helps!
Answer:
1.50
Step-by-step explanation:
Answer:a)117 hours b)4.875days.
Step-by-step explanation:
Using the formula
Speed =Distance / Time
Given Distance = 3 3/5 -mile
and Speed=2/65 miles per hour.
Time =Distance / Speed
Time = (3 3/5)/(2/65)
Time =18/5÷2/65
Time =18/5 x 65/2 =117 hours
Now 24 hours =1 day
therefore 117hours =(117hours x 1 day )/ 24 =4.875days.
