X * .64 = 1200
x * .64/.64 = 1200/.64
x = 1875

When can you use the square roots of perfect squares to determine the perfect roots of decimals ?
Alika [10]
If you want to find the decimal value of a square root, you can use the 2 closest perfect squares to them.

Example

Approximate the value of sqrt20

Pick the 2 closest perfect squares, one before and one after 20:

16 and 25.

So, the square root of 20 has to be between 4 and 5.

Since 20 is closer to 16 than it is to 25,

We can estimate the decimal value of sqrt20 to be around 4.4

Is domain of f(x,y) = 1 + (4 -y^2)^1/2 open, closed or neither<br><br> 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.
