Answer:
L = 70 W = 40
Step-by-step explanation:
P = 220 ft
W = L - 30
I started guessing numbers for L that would work. When I did this, I made sure that all of the sides added up to 220 ft.
Where x is 4 the corresponding y is 5. Your answer is 5.
<span>Your answer is -0.5 hope it helps:)
Also, I changed my pfp so know it's not team 10 no more</span>
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.
