It would be 2^12 (to the twelfth power) What you do is you multiply the power that's inside of the parentheses and the one on the outside. Since they are both negative, the power will end up being positive. And if you need to multiply it out, it would be 4096.

A blueprint for a house has a scale of 1:5 feet. The living room has a length of 2.5 inches and a width of 3 inches. What is the

stiks02 [169]

Answer:

Step-by-step explanation:

Set this up as a proportion, with inches on the top and feet on the bottom for our scale. We will find the actual length first, then we'll find the width.

$\frac{in}{ft}:\frac{1}{5}=\frac{2.5}{x}$

Cross multiply to get that the actual length is 5(2.5) = 12.5 feet. Now for the width:

$\frac{in}{ft}:\frac{1}{5}=\frac{3}{x}$

Cross multiply to get that the actual width is 5(3) = 15 feet.

If you want the area of the room, multiply the length times the width to get

A = 15(12.5)

A = 187.5 feet squared

Answer:

Step-by-step explanation:

a) The domain is R- all real numbers.

b) The domain is R- all real numbers.

c) we need

$x^{2}-4\neq 0\\x^{2} \neq 4\\x\neq 2\\and\\x\neq -2$

So the domain is R\{-2, 2}

we need

$x^{2}+x-2\neq 0\\x\neq 1\\and\\x\neq -2$

So the domain is R\{-2, 1}

we need: x-1>0 or x> 1

So the domain is (1,+∞)
