Answer:

127 1/2 feet

Step-by-step explanation:

A model lighthouse uses a scale of 1/4 inch = 5 feet.

This means that 1/4 inch on the model represents 5 feet in actual life.

The height of the model lighthouse is 6 3/8 inches i.e. 51/8 inches.

The height of the actual lighthouse is:

1/4 inch = 5 feet

51/8 inches = x

Cross-multiply:

51/8 * 5 = 1/4 * x

=> x = 51/8 * 4 * 5

x = 127 1/2 feet

The height of the actual lighthouse is 127 1/2 feet.

1 + 1.5x - 3 is one possibility. That's what you get when you remove the brackets.

Is domain of f(x,y) = 1 + (4 -y^2)^1/2 open, closed or neither is it bounded or unbounded?

omeli [17]

Answer:

Closed and Bounded.

Step-by-step explanation:

Hi there!

1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:

$f(x,y) = 1 + (4 -y^2)^{\frac{1}{2}} \:id\:est\:f(x,y)=1+\sqrt{(4 -y^2)}$

Since every quadratic root are defined for values $\geq$ 0 then, this help us to understand that we need calculate what interval this Domain is:

$4-y^{2} \geq 0\\4-y^{2}-4\geq -4\\-y^{2}\geq-4 \\y^{2}\leq4\\-2\leq y\leq 2$

$D=[-2,2]$

2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.

Bounded functions have all of their points contained by some circle origin centered. Check it out below.
