Well us as kids are constantly on the computer and phones so google classroom is a great way to keep us connected with our teachers because we can communicate with them and they with us by posting assignments. Therefore we are less likely to forget what they told us in the classroom because it is just one click away.

HELP SOLVE THANK YOU!
Lera25 [3.4K]

Answer:

Solution 1: 1+1\sqrt{3}

Solution 2: 1-1\sqrt{3}

Step-by-step explanation:

x^2-2=2x

x^2-2x-2=0

Use quadratic equation.

(-b+-\sqrt{b^2-4ac})/2a

(2+-\sqrt{(-2)^2-4*1*-2})/2

(2+-\sqrt{(4+8}))/2

(2+-\sqrt{12})/2

Solution 1: (2+2\sqrt{3})/2=1+1\sqrt{3}

Solution 2: 1-1\sqrt{3}

Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has  only 1 cube, then there are 48 layers.

True or false: sec^-1(0.5) is undefined. explain your answer
ICE Princess25 [194]

Here we get the statement:

"sec^-1(0.5) is undefined"

And we want to see if this is true or false, so let's use the properties that we know to find that this is false.

Remember that the sec function is defined as:

sec(x) = \frac{1}{cos(x)}

Then we will have:

sec^{-1}(x) = (\frac{1}{cos(x)})^{-1} =  cos(x)

Then is really trivial to see that:

sec^{-1}(0.5) =  cos(0.5) = 0.878

Then we can conclude that the function is not undefined at 0.5, so the statement is false.

Below you can see the graph of the given function, and you will see that it is never undefined.
