If the domain of f(x)=-x² is integer values of x such that -3≤x<0, find the range.

slamgirl [31]

The range is the resulting y-values we get after substituting all the possible x-values.

$\text{The domain:}\\\\-3\leq x < 0\to\{-3,\ -2,\ -1\}\\\\\text{The range:}$

Substitute the values of x to the equation of the function:

$f(-3)=-(-3)^2=-9\\\\f(-2)=-(-2)^2=-4\\\\f(-1)=-(-1)^2=-1\\\\\boxed{\{-9,\ -4,\ -1\}}$

The two guy wires supporting a tower form an isosceles triangle with the ground. Each of the base angles of the triangle is 2 ti

agasfer [191]

Answer:

The measure of the vertex angle is 36 degrees.

Step-by-step explanation:

In order to find this, we set the vertex angle as x and the base angles as 2x. Now we can add all three angles together and set equal to 180.

x + 2x + 2x = 180

5x = 180

x = 36

think about the different things that 5- 2 could mean. using these meanings, what should - 2 -2 mean if u know the answer can u

vampirchik [111]

Is this what you are looking for?
So what I did was that I put the 5 and the two as a whole number, and I just put the minus sign in the middle. Then, I did the "change to the opposite" thing. What u do is u put the five normal then you put a plus sign then a - 2 (negative two), and at the end u just do 5 minus 2.
It's kind of confusing but You'll get it some day :)
