Step-by-step explanation:
So, you need to add 
on both sides of the quadratic equation.
It would be 12 since the middle numbers are 11 and 13 you take the number in the middle
Answer:
h(1.5) = 7.3 ft
h(10.3) = 24.9 ft
Step-by-step explanation:
Given the function h(d) = 2d + 4.3,
where:
h = height of the water in a fountain (in feet)
d = diameter of the pipe carrying the water (in inches)
<h3>h(1.5)</h3>
Substitute the input value of d = 1.5, into the function:
h(1.5) = 2(1.5) + 4.3
h(1.5) = 3 + 4.3
h(1.5) = 7 feet
The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.
<h3>h(10.3)</h3>
Substitute the input value of d = 10.3, into the function:
h(10.3) = 2(10.3) + 4.3
h(10.3) = 20.6 + 4.3
h(10.3) = 24.9 feet
The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.
<h3>Context of the solutions to h(1.5) and h(10.3):</h3>
The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain. The height of the water in fountain increases relative to the diameter of the pipe. In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.
4b is equivalent to b+b+b+b
Answer:
B
Step-by-step explanation:
To answer this, we need to see the to see to the fact that they are both in the same unit before we can take the ratio.
Firstly, we know that 1 foot = 12 inches. 9 feet would this be 9 * 12 = 108 inches.
Now we are told to get the ratio of length of car to length of model.
This means 108:6 = 18:1
