Answer:

It has the same domain as the function f(x)=-\sqrt{-x}

Step-by-step explanation:

we have

f(x)=\sqrt{-x}

we know that

The radicand cannot be a negative number

so

-x\geq 0

Solve for x

Multiply by -1 both sides

x\leq 0

The domain of the given function is the interval ----> (-∞,0]

All real numbers less than or equal to 0

The range of the given function is the interval ----> [0,∞)

All real numbers greater than or equal to zero

<u><em>Verify each statement</em></u>

Part 1) It has the same domain as the function f(x)=-\sqrt{-x}

<em>The statement is true</em>

The domain of the function f(x)=-\sqrt{-x} is

the interval ---> (-∞,0]

Part 2) It has the same range as the function f(x)=-\sqrt{-x}

The statement is false

The range of the function f(x)=-\sqrt{-x} is

the interval ---> (-∞,0]

Part 3) It has the same domain as the function f(x)=-\sqrt{x}

The statement is false

The domain of the function f(x)=-\sqrt{x} is

the interval ---> [0,∞)

Part 4) It has the same range as the function f(x)=-\sqrt{x}

The statement is false

The range of the function f(x)=-\sqrt{x} is

the interval ---> (-∞,0]

Answer:

Y=109 X=31

Step-by-step explanation:

Alright, so the angles that you have to find the values for make up 180 degrees. Since you have 71 degrees on the bottom, and according to a certain theorem I forgot about, that means that the angles you're solving for equal 109 degrees.

X= 31 because 4 x 31 = 124 and then 124 - 15 equals 109

find the missing angle and side measures of the triangle. The triangle has one angle that measures 90 degrees, and the other two
Tamiku [17]
Since we know that the measure of one of the angles is 90°, we know that we have a right triangle with legs 1 and \sqrt{3}. Now lets apply the Pythagorean theorem: hypotenuse= \sqrt{leg^{2}+leg^{2}  }, to find our hypotenuse:
h= \sqrt{1^{2}+ \sqrt{3}^{2}   }
h= \sqrt{1+3}
h= \sqrt{4}
h=2

Now that we know that the measure of the hypotenuse is 2, lets use the trig function sine to find one of the angles that we are going to call x.
Remember that sin(x)= \frac{opposite.side}{hypotenuse}, so:
sin(x)= \frac{1}{2}
x=sin^{-1} ( \frac{1}{2} )
x=30
Now that we have two angles, remember that the sum of the interior angles of a triangle is 180°; lets use that to find our final angle y:
y=180-(90+30)
y=180-120
y=60

We can conclude that the measure of the hypotenuse of our triangle is 2, and the measure of its missing angles are 30° and 60° respectively.
