Answer:
A: g(x)
Step-by-step explanation:
The equation is technically in vertex form "y = a(x – h)² + k", where the vertex is (h, k).
For the domain and range to be as stated in the problem, your "vertex" needs to be (2, 3), and so you want y = a(x – 2)² + 3 which is answer choice A

Answer:
412.15 ft to the nearest hundredth
Step-by-step explanation:
You have to use the tangent function since you are given one leg of a right triangle and you are looking for the other leg
Let x = the distance from boat to lighthouse
So, tan 27 = 210/x
x tan 27 = 210
x = 210/tan 27
x = 412.14820 = 412.15 ft to the nearest hundredth
We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12
The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.
