Step-by-step explanation:
It is given that,
The length of section 1 is 0.75 m and the length of section 2 is 15/100 m. The total length of the section is equal to the sum of section 1 and section 2. So, we will add them as follows :
So, the length of the section is 0.9 m or 9/10 m
For the given function, the domain is D : { x ≥ 7} and the range is R: { y ≥ 9}
<h3>
How to get the domain and range?</h3>
Here we have a square root, remember that the argument of the square root must be equal or larger than zero, so the domain is such that:
x - 7 ≥ 0.
Solving for x we get:
x ≥ 0 + 7
Then the domain is:
x ≥ 7
To get the range, we evaluate in the minimum of the domain:
f(7) = √(7 - 7) + 9 = 9
Then the range is the set of all values larger than 9, because the function is increasing.
So the range is R: y ≥ 9.

Step-by-step explanation:
Answer: 70.00$
Step-by-step explanation:
The question states that it takes 20 gallons of gas to get there, and the cost of three gallons of gasoline is $10.50.
so
20/3 * 10.50=70$
The answer would be (-3+18) + (i +5i)
This is because changing the order of the numbers does not change the sum
